This is an unofficial build of LineageOS 16.0 for the Motorola razr I, (XT890/SMI).
Lots of thanks to Hazou. This rom is based on his los-14 rom and I got help from him with los-16.
This rom has full hardware support and should run stable. It has been tested by me in daily use. I'm using the rom without google apps, but with microg. Installing google apps requires some apps to move to data partition because of limited system size. See install description for more info.
Special Features
-All features of Hazous 14.1 rom
-MicroG signature spoofing patch is included.
-Adaptive icons can be disabled in homescreen settings.
I can include more features if requested
Known Bugs
-The camera preview image sometimes shakes at random

Update
If you already run an earlier version of this rom, just boot to twrp and install the latest flashable zip file
Install
1. Backup everything you don't want to loose.
2. Download and install TWRP 3.2.3 (download in attachments. Can be flashed with fastboot or with another recovery)
3. If you come from another rom do a full wipe with twrp
4. Download and install the rom flashable zip (download from mega.nz link is in section download)
5. If you want to install opengapps or need system partition space for other things. Install the move_to_data.zip file from the attachments. This will move the Webview and the LatinIME app to data partition.
6. Choose one of the following options:
-either install google apps (download form https://opengapps.org/. Choose x86 9.0 nano or pico)
-or install MicroG (can be installed with the unofficial installer https://forum.xda-developers.com/android/development/microg-unofficial-installer-t3432360) this is lighter in ram and cpu usage but you will get problems with google chrome and other apps
7. If you want root access install the addonsu-16.0-x86.zip (download in the attachments)
8. Reboot the phone. First reboot will take some time

DATA Encryption
If you want to enable data encryption this would break the pds partition backup. To prevent this, the cache partition can be used as backup location:
-edit /system/bin/pdsbackup.sh
-change PDS_FILE=/data/misc/pds/pdsdata.img to PDS_FILE=/cache/misc/pds/pdsdata.img
-resize data partition in TWRP:
Code:
umount /data
umount /sdcard
e2fsck -f /dev/block/mmcblk0p17
resize2fs /dev/block/mmcblk0p17 1367079
-reboot the phone

This if I did not expect it, I'll try to see how it goes. Thank you.
Download links and install description are up now. Download from mega.nz because xda download section is broken at the moment. I'm waiting for your test reports
It's really great works, thank you!!
I quickly tried and found several points.
- USB connection with PC
All USB connection option including File Transfer, USB tethering, PTP are grayed out.
Disabling/Enabling android debug in setting didn't work.
- Wifi with storage encryption
When you enable storage encryption, WiFi always become disabled, not be able to enable.
Just FYI, it required deleting /system/bin/pdsbackup.sh AND reducing partition size of 'data' (/dev/block/mmcblk0p17).
- SElinux
Although it is designated as permissive in device.mk, it's actually worked as "disabled".
I'm not sure it's related or not, however, when building "user build", it's failed with "ERROR: permissive domains not allowed in user builds".
I know "user build" is not officially supported in Lineage release, however, it's really helpful if we can do it for AFW usage.
Previously I could use Lineage 14.1 smi build for AFW and safetynet app with user build.
BTW, performance is really great, seems to be almost same as Lineage 11.

I also noticed that. Will see how this can be fixed. It is just a problem with the option dialog. Usb connection works fine. As a workaround you can set a default USB configuration in developer options

I think lineage trust doesn't differentiate between permissive and disabled. Selinux support is planned for future releases
Thank you for quick check.
Regarding USB connection, I also confirmed that Ubuntu can recognize as external storage with above option, besides Windows still does not recognize. Maybe depending on my environment.
Also I noticed that Chrome, Chrome Beta and Chrome Canary (therefore another Chrome based apps such as Maps Go) always crash. This is also maybe my environment only, though. BTW, I could install MicroG, besides couldn't install OpenGapps 9.0 pico due to partition size limit.
Additionally, I couldn't find any LED settings, currently LED is always off during charge or any notification.

Notification Led should work. Can be configured under settings->apps and notifications->notifications->notification light. I don't know what happened with the battery light. It will hopefully come back if I upgrade the driver to hidl.
Google Chrome is a known problem with MicroG. It requires official gapps. I will check if some of the unprivileged lineage apps can be moved to data partition to make place for google apps
Newbie question
Hi all, I know someone who's selling her old RAZR i XT890 and I'm interested (for experimental reasons but also the oddity that it's Intel powered). I've never owned a RAZR i so I've got some questions:
-The phone is from 2012 so quite old and has 1GB RAM, does it work well with this Lineage 16? Because usually newer software would perform bad on older SoC (I used to have iOS 7 on iPhone 4 back in the day and it was painfully slow compared to 6).
-On Lineage 16, can it run any Android app as a standard new Android Pie phone? I ask because this is an Intel x86 CPU, so can it still run Android apps as normal or are most of them only designed for ARM and therefore unusable?
If I get the good news, I may buy the phone and try this Lineage OS custom ROM.
Regarding LED, maybe it became working after modifying some option of notification light. Battery connection light is still always off.
Regarding opengapps, I moved webview and LatinIME from app directory to external SD in TWRP, then installed as normal app after system boot. Webview worked fine besides LatinIME always crash. I'm using different IME, so it's no problem. With this environment, opengapps nano can be installed, then Chrome, Maps and other google apps worked.

That's good. Than we can make a flashable zip to automatically move and symlink them to data partition.
I will provide a new build till end of the week with improved usb and notification LED implementation. I already got it working in my local setup

Newer android versions have been designed while keeping low ram devices in mind. Ram hungry special features like the picture in picture mode are excluded from builds for older device. So the situation is much better then on iOS. But a newer phone would run better thought.
Most android apps are available for x86. But some are still arm only and get automatically emulated. The intel houdini emulator integrates these apps natively into the system but they are a bit slower then x86 apps. These are for example Skype and a few unity based games

Thanks for the response. So I should be alright with it then, hopefully. I just hope it won't lag on that old SoC. I'd love if you could upload a quick video of it in action.

Yes, system partition size is limited on this phone. To install GApps some files need to be moved to data partition.
I created a flashable zip to automate this process. Take a look at the modified install description in the first post

Sorry don't have enough time to make a video in the near future. Maybe someone else can record a video of it
I could confirm that notification LED and USB storage works fine with lineage-16.0-20190713-UNOFFICIAL-smi. Thanks.
Still WiFi with storage encryption does not work.

Alright, thanks. I bought my friend's RAZR i and I am planning to use it as a daily driver with this ROM (I'm a light user anyway), I can't thank you enough for making this LineageOS for such an old device. I wonder if such a recent Lineage has been developed for the 2011 Atrix, haven't seen one.
I have questions though, firstly I've never used a custom ROM before, can I simply follow the instructions on this thread to get it working, or is there anything that has to be done beforehand like rooting? Secondly, are any other OSs successfully booting on this x86 phone, as I can't find it on XDA? (it surprisingly hasn't gotten much attention as a hackable device like HTC HD2 or Nokia N900 got).

If the phone never had a custom rom yet, you have to unlock the bootloader first. Description is in this thread: https://forum.xda-developers.com/showthread.php?t=1928551

I'm not sure if I misunderstood but when you said "it required deleting....." and "reducing partition size of data", did you mean you can get WiFi to work if you do those things? I'm no expert at these but I can atleast apply the "fix" (if it really is) given that you guide me, if it's okay with you. Thanks!
Hi all:
Here is a LineageOS 17.1 ROM for Z5 compact (suzuran).
Download 2022-09-11
This is a 7z archive with the zip'ed rom and the md5 file in it. Please unpack this archive, copy the included two files somewhere to your device, reboot into TWRP and flash this zip file. Enable md5sum checking. The zip file itself is not signed, so you have to disable zip verification.
Kernel sources
Tree sources
Features:
OS Version: 10.0 (Q)
Kernel: Linux 3.10
Kernel 3.10.108
New: Android security patch level: 5 September 2022
Using sony blob's from stock version 32.4.A.1.54
Memory issues finally fixed!
Battery consumption significantly reduced! For further reduction, please follow these instructions.
Google Pay does not give an error when starting the app. This does not mean, that payment is working. I can't test it, because I don't use this feature at all. Please report if it's working or not.
Updated aptX encoder blobs.
P2P-Crashes fixed.
Important informations:
You should be familiar with general installation of custom ROMs.
Required for installation: TWRP 3.2.1 (pick the version from 2018-02-23!!!) There is a version 3.2.3 out there, but with that version I had problems to restore my backups. 3.2.1 is just working perfect for me!
OR use my self built TWRP-version 3.6.2!
This ROM needs a clean install, old /data may cause problems!
This ROM is NOT pre-rooted.
It is highly recommended that your device is running (or HAS RUN in the past!) the latest stock ROM from Sony (32.4.A.1.54) before flashing this ROM.
Otherwise the baseband files may not match.
Working:
Bluetooth
Camera; both built-in camera (Snap) and 3-rd party camera apps.
Snap may be a little bit laggy, please use 3-rd party camera app instead; for example OpenCamera. If you're running into errors, please report.
Enforced SELinux support (see attached screenshot)
Fingerprint
FM-Radio
GApps (pick this version: ARM64, 10.0, pico [tested])
German app AusweisApp2 working (see this post)
GPS
Headset
LiveDisplay (see attached screenshots)
Location services
Notification LED
Offline charging
Phone calls (see attached screenshot)
SafetyNet test passed successfully
Signed build
SMS
Torch
WiFi
These things are NOT (or badly) working:
Camera focus at low distances.
Encryption
Payment
Streaming (mirroring)
VoLTE
Maybe some more things are not working.
If you have problems with GApps:
Sometimes the SetupWizard of GApps crashes on and on. Then you have to boot into TWRP, mount system, and go into terminal, where you have to delete SetupWizard (see screenshots):
Code:
cd /system/system/priv-app
rm -rf SetupWizard
Reboot.
Use this rom at your own risk! It comes without any warranty! I'm not responsible for any damage! If you don't agree with that, don't try to flash this rom in any way.
Benefits:
Added F-Droid and UnifiedNLP! If you don't want this, simply de-install it.
I've set maximum speaker volume to a higher value.
I've increased microphone gain.
I've changed the microfone gain to avoid echo in phone calls.
Changelog
Troubleshooting:
If you're running into an error, please search in this thread if this error is already posted, before you post it again!
If not, I need a LOG to see what went wrong. Without a LOG I can't help you!
A LOG can be fetched by connecting the device with an USB cable to your PC and then by typing these commands line by line:
Code:
adb root
adb shell logcat -b all -d > logcat
Send my this LOG file via PM.
If you think this could be a SELinux related issue, please try to set the device to permissive mode first.
If the issue is gone, I need the policy file too (plus LOG). Fetch it by typing this line in a terminal:
Code:
adb pull /sys/fs/selinux/policy
If you stuck in a bootloop you can fetch a LOG with this trick:
Press the power button and the volume up button together until the device shuts down.
HOLD the power button.
Release the volume up button and press the volume down button immediately after releasing the volmue up button.
The device should start into TWRP recovery.
Tap on "Advanced", then on "Terminal" and enter these commands line by line:
Code:
cd sys/fs/pstore
cp * /sdcard
Send me the copied file(s), if any, via PM.
Hi Bernie,
First things first : Thank you so much for your amazing work on this device.:highfive:
So hard to find a good, compact and up to date smartphone.
So i tried your Los17.1 and i just noticed another issue : ram usage.
Without nor the gapps neither other apps installed, the system is using 1.6go ram (even the keyboard can take time to appear once you launch an app)
On your Los14.1 (i tried with the last one you created, a few days ago) : it would be something like 0.8go ram (so everything run smoother) still without gapps and other apps / settings.
Maybe, now our days, 3go ram is mandatory for android + gapps + 3rd party ...

I know about that. I've tried with gapps and I can confirm that ram is running out of free space. Sometimes the system is not responding any more (screen is flickering and it seems that nothing happens) and I have to restart it (press power button quite a long time until power menu appears).
It is indeed far away from being a daily driver... :angel:
Another issue: It seems that location services (gps) are not working.
Does anybody confirm that?
Although Bernard warmed us that this ROM is not precisely ready yet, I tried to give it a go, Twice, already. At each time, some variations: with and without gapps (Pico and Nano), via the recommended TWRP and the 3.3.1 one. The result is always the same: after the language selection, my phone reboots on the 'Just a sec', endlessly. I have to restore a nandroid backup, on order to have a working phone again.

Weird! At my device this popup comes in the moment when trying to make an outgoing call. And this call is not started! The other end does not ring!
Could you please tell us, which preferred network type is set in *#*#info#*#* "Phone info" and in "Mobile network settings" (see screenshots)?

Pretty strange, indeed.
The phone i tested with is on another provider than my z5c.
I got to say that i checked the apn before making my tests, and they were good.
I will retry with the new version tonight .
Thanks
The APN shouldn't matter for regular calls unless you're using Wifi calling or VoLTE, maybe disable both and see if it works.

You MUST READ posts 1-4 (about 10 minute read) before deciding to install this rom. If you think this is an unreasonable request, then stop reading now and find another rom. Thank you.
DISCLAIMER
I am not responsible for lost data, identity theft, lost money, security vulnerabilities, bricked devices or any other hardware or software malfunctions that comes as a result of flashing this rom.
All involved in bringing this build to you are working voluntarily on it in very limited spare time, and their other life commitments have much higher priority. Don't expect a prompt, or even any, response to questions and bug reports.
Before attempting to install this ROM
1. Ask yourself: would bricking your device be a disaster for you? If yes, don't try this ROM! It can't be guaranteed stable and reliable enough to depend on for daily use.
2. BACKUP YOUR DATA AND EXISTING ROM. Be prepared for a complete restore if anything goes wrong.
3. RESEARCH adb, fastboot, Odin/heimdall, and TWRP and how to use them, if not already familiar with these.
What works
1. bluetooth
2. wifi
3. brightness
4. external audio
5. GPS
6. audio through headphone jack
7. audio over bluetooth
8. selinux enforcing
9. DRM level 3 (SD definition)
10. deep sleep
What doesn't work
1. fingerprint. As I wrote in post 1891 at
https://forum.xda-developers.com/t/...t810-t815-t815y.3879302/page-95#post-85533725
I will not spend anymore time looking at fingerprint. If you need fingerpint to work, stay with stock Samsung rom.
2. DRM level 1 (no HD definition). There's more detail in post 1891 above. I will not be trying to achieve level 1 for HD definition. If you need HD definition for your $treaming media, stay with stock Samsung rom.
3. If you charge the device while it's powered off and then want to power it on, you MUST wait at least 30 seconds AFTER disconnecting the charger cable before pressing the power button otherwise you might run into strange boot problems such as the touch screen not working.
4. Possibly other features that I haven't tested or do not use.

Frequently Asked Questions. You MUST READ this before posting any questions. Thank you.
QuestionAnswerQ1. Can I build this ROM for myself? Where are the source and kernel source files?A1. Yes, you can. The source files are listed below.
Kernel
https://github.com/retiredtab/android_kernel_samsung_universal5433-selinux
Device Tree
https://github.com/retiredtab/android_device_samsung_gts2-common-selinux
https://github.com/retiredtab/android_device_samsung_gts210wifi
Vendor
https://github.com/retiredtab/proprietary_vendor_samsung-selinux
In addition, there is a repo diff file for device-specific tweaks needed to work and a roomservice.xml (local manifest file) file so you can build this rom yourself. The other patch required for tcp/ip is at https://github.com/DerpFest-11/pack...mmit/22fd53a977eeaf4e36be7bf6358ecf2c2737fa5eQ2. Is this ROM suitable as a daily driver?A2. It might be, depending on your requirements. You would need to try it yourself, with your preferred apps, to see if suits your purposes. I've been using it myself since mid August 2021 with no major issues.Q3. What do I do if my app xyz doesn't work?A3. I can't help diagnose problems with random apps I know nothing about. If the app is critically important to you and it doesn't work on this ROM, go back to a ROM where it did work.Q4. Why is this ROM laggy and/or buggy?A4. The device will be noticeably slower if you're using any Gapps package. Consider going gapps-free. A lot of apps will work without Google's services, or there exist alternatives that will. Check out F-Droid, Aurora Store, NewPipe, etc.Q5. What TWRP should I use?A5. You MUST use TWRP 3.5.2_9. Get it from
https://dl.twrp.me/gts210wifi/Q6. Why should I use this ROM?A6. You don't have to! If you don't like it, go back to your old ROM.Q7. Will you offer monthly updates with security patches?A7. We plan to do so. Yogi555 will try to update the ROM with the monthly security patches after LineageOS has released them, free time permitting. Each monthly build will be tested to make sure all the "What works" functionality listed in post #1 still works, before it's made available (which might in some cases delay the release).Q8. I'm a newbie. Can you provide step by step instructions?A8. We simply don't have the time to do this, but there are lots of tutorials, videos, etc online showing how to flash custom ROMs and how to deal with common problems. Newbie questions are also accepted in the XDA General Questions and Answers forum. Having said that, @pflyaz has kindly make a guide in in post #16.Q9. Can I report a bug with respect to the ROM?A9. Yes, but you need to supply the following information. If you don't, I won't look at it.
Provide an adb logcat of the problem, and if possible describe how to reproduce it. Note that I can't help if it involves downloading any app I don't already use that requires payment or creating a userid/password.
To get a logcat, open a terminal window on your PC, connect your device to it via USB, and do this:
Bash:
# clear the logcat first
adb logcat -c
# start logcat trace
adb logcat > problem.txt
# reproduce problem
# wait until problem has occurred,
# then stop trace by hitting ctrl-c then zip the problem.txt file
# before uploading it.
Q10. How long will you build 18.1 for this device?A10. For now, 18.1 will be built for all of 2022. After that, we will make a decision depending on a number of factors.Q11. Do I need to erase everything and format my data before installing this ROM for the first time?A11. Under most circumstances, yes.
If you're coming from stock Samsung Android, or an earlier version of LineageOS, or a different custom ROM, you MUST 'clean flash': boot to TWRP recovery, wipe system, data, dalvik/art cache, and cache partitions, then Format Data, then install this ROM.
If you don't do this you're likely to run into problems, such as getting stuck at the boot animation for more than 5 minutes.
The ONLY exception is that if you are coming from LOS 18.1 with the April 5 2022 security patch or later, you can dirty flash the latest security patch build.Q12. What Gapps should I use?A12. Your choice! There are several well-known Gapps packages, such as NikGapps, BiTGapps, OpenGapps, and MindTheGapps. OpenGapps is being removed as per post #14. Do your own research as to what is the most reliable gapps option for you.
I recommend installing the SMALLEST version of any of these, preferably with just the minimum Google services needed to access the Play Store and run apps that depend on Google services.
You could also consider Google alternatives, such as Aurora Store, which mirrors the Google Play Store apps but doesn't need any Google services itself. Many Play Store apps do not actually depend on Google services.
If you are going to install any Gapps package, follow the installation instructions given for that particular package.Q13. I'm having problems with Gapps. Can you tell me why it's not working?A13. I can't answer any questions about Gapps, because I don't use them. Ask your questions on the XDA thread for the Gapps package you're using.Q14. Why isn't my post answered?A14. There are several possible reasons: the question is answered in the FAQ (in which case it will be ignored completely); or it involves apps or operating systems that I don't use; or it's about Gapps, which I don't use; or I simply have not had time to answer any questions.Q15. What speed up/optimization tips do you suggest?A15. These steps can make a big difference to performance:
Turn off animations. Go to Settings > System > Developer options, scroll down to the Drawing section, and set Window, Transition and Animator scale all to "Animation off".
Don't install Gapps unless you depend on something that only Google is providing. Use Aurora Store to get your preferred Play Store apps - they will all be available on Aurora Store. You can choose to access this anonymously or use a Google account.
Don't run more than two apps at the same time. You can probably listen to music in the background and use a web browser at the same time.
Use a web browser with built-in adblock and privacy features, such as Brave.
Use NewPipe to watch your streaming content. It has built in adblock so you don't have to watch forced ads.
Look for apps that are open source, ad-free and lightweight.
Q16. Does this ROM support Magisk so I can root my device?A16. Magisk works with this ROM as reported by beta testsers, but that could change with any revision and changes by Google. However I don't use it myself and can't help with any related issues. Direct any questions about Magisk to the XDA Magisk forum.Q17. Will this ROM ever become official?A17. Never. Official maintainers have onerous responsibilities, and I know my device trees, code organization and git commits will NOT meet LineageOS standards. I'm not able or willing to take on the responsibilities and commit the extra time to supporting an official build.Q18. What is the difference between this ROM and others?A18. This ROM tries to be pure LineageOS with little or no modification. Other ROMs may come with a different UI, different bundled apps, etc.Q19. Will there be any major 18.1 code modifications in the future?A19. I don't anticipate any major modifications. There may be some slight tweaking to the SEpolicy, small bug fixes and minor code cleanup, but all the hard work - getting the rom up and running, and fixing all the major bugs - has been done. This doesn't mean the code is perfect or well organized, but I won't be making any major changes.Q20. Why did you fork the trees?A20. I wanted my own private branch where I could make changes that would only affect my own personal builds.Q21. Can you build a variant of this device? For example, a LTE or S-pen version?A21. I cannot and will not try to build for a variant device if I don't physically have that device. I have to be able to boot and test it myself, and there's no guarantee that I can get those variant features working. So I will NEVER build T715, T810 and T815.Q22. Can I load this ROM on a variant device like LTE or S-pen version?A22. This ROM is for the device explicitly listed and will only work on that device. Do not try to install it on any other device.
ONLY if you are an advanced user and understand TWRP, adb, odin, heimdall, etc, you could try loading it on a LTE or S-pen variant by modifying the updater-script, but be warned: there are likely to be problems, including a bricked device, bootloops, or the ROM not being able to support the functionality of LTE/S-pen.Q23. Does this ROM have any wifi connection issues?A23. This ROM's wifi has been stable on the specified device ever since lpedia and I determined the root cause of the wifi problems back in July 2021 and re-installed the original S2 network 'blobs' with LOS 17.1.Q24. Is this ROM secure so I can do financial transactions?A24. Although Android monthly security patches do improve general security, this ROM's outdated kernel and old proprietary vendor blobs/drivers will NEVER get updates of any kind, and could have significant security holes.
In addition, although the ROM is SElinux enforcing, there's a good chance that the rules written (about 800+ lines of code) have some errors.
If the device is rooted, this would further weaken the security.
With this information, it's up to you to make an informed decision about whether you trust this ROM to be secure enough for your financial transactions.Q25. Okay, I understand the consequences and willing to take the risks outlined, now where can I find the BETA rom?A25. Downloads are at

Tried the beta build and everything seems to be working. I'll observe once it goes into deep sleep and see if WiFi will lose connection (usually 24 hours) on the other 18.1 build. Loaded all my paid apps without issues. Only gripe is the Netflix with DRM L3. Will look into another thread where they spoofed it.
I'll give it a try. Other LOS 18.1 roms wifi not working.
@retiredtab, @ananjaser1211, @lpedia, @Yogi555 and @CuckooPenguin thx very much for your work.
Until yesterday mine was on ripees build from 20211103 which was stable and working but didn't seem to get any further updates than 20211208.
Clean installation went well although I didn't follow "Q5" and used latest TWRP which is 3.6.1_9-0.
Flashed it with Magisk 23. (wanted to make sure that Gapps didn't interfere)
1st boot was fast, setting it all up.
Looking in settings for button backlight duration but didn't find it (using it in the night and want them to light up as short as possible).
Wifi connection there as soon as it wakes up.
So I gave BitGapps a go and flashed ARM64 which worked (isn't specified in "Q12" and as far as I remember only ARM worked on ripees build).
Fiddling around a bit installing paid apps and others.
Everything seems to be fine especially for a beta version.
For others who want to change from ripees version to this one:
On mine it worked to restore "Data" via TWRP (partition got wiped again before) what makes it much easier to switch.
Each app I use seems to be working under the new ROM without problems.
Fun fact: button backlight after restoring is as short as it was set in the prior ROM.

The reason I write MUST is that not all TWRP from the official TWRP site work properly. For example, when I was initially building the 18.1 tree back in July/Aug 2021, I needed mtp and adbd to work in TWRP T710 for debugging purposes.
Despite the change log claiming both were fixed, not a single version worked wrt mtp and adbd. I knew this way back in Dec 2020 and you may have even seen my post #124 since you were post #122 and #126 in the same thread.
So in order to get 18.1 up and running, I fixed TWRP T710 myself as I explain at
https://forum.xda-developers.com/t/recovery-unofficial-twrp-3-5-2_9-for-samsung-sm-t710.4430335/
So for T710 users, I know my TWRP build is rock solid as I have easily used it more than 150 times when making the 18.1 rom.
Another example. During the summer of 2020, I upgraded the OS on a Samsung S4 phone for my friend. I went to official TWRP website, downloaded the latest and much to my surprise, the touchscreen didn't work at all. I used an older TWRP version and it worked fine.
Bottom line: even though it's on the official TWRP website does not mean it's tested or working properly. In the case of the S4 TWRP with the non working touchscreen, it's obvious there was zero testing done.
That's why we will test ALL our 18.1 builds for the "what works" functionality in post #1 before uploading to the general public.

By sheer coincidence, I already had the above in my private build on March 27 as I wanted to test it to make sure it works before adding it into github. Yes, I test even 1 line of code change myself no matter how trivial.
The 1 line of code needed is documented at
https://review.lineageos.org/c/LineageOS/android_device_samsung_s3ve3g-common/+/292889
I will put this change into my github so that it gets built with the May 5 security patches.

My github repo has always had the S2 wifi blobs after @lpedia and I fixed it on Aug 7, 2021 as per
https://github.com/retiredtab/propr...mmit/3984c2ef6852794a939b8eda689fc477705d5c86
As you can see in my github history, that reversion back to S2 wifi has never changed since Aug 7, 2021.

Without looking through the 1000's lines of code or more, the above functionality exists probably in the hardware/samsung repo
https://github.com/LineageOS/android_hardware_samsung/tree/lineage-18.1/hidl/light
and the settings are probably saved in some directory, but the display menu for the button backlights isn't shown until I put in that one commit above. That is, the OS knows to use the saved settings, but without the menu overlay, it doesn't show the menu itself.

Well I gotta admit I didn't check adb and mtp in that TWRP.
I probably saw your post but might not have paid attention as they referred to T710 and as I own T810 I judged them as not relevant for me.

The settings seem to be in the file /data_mirror/data_de/null/0/org.lineageos.lineagesettings/databases/lineagesettings.db
When opening in DB Browser I found:
In table "secure" the lines
46 "button_backlight_timeout" (value 1000 [probaly for milliseconds as I set it to 1s in ripees ROM]) and
47 "button_brightness" (value 1.0).
In table "system" the line
47 "button_backlight_only_when_pressed" (value 1).
Never worked with .db files myself before but for the knowing it might be interesting if they want to fiddle around a bit.

May 10, 2022 release notes
1. YOU MUST read posts 1-4 if you haven't already
2. Added overlay for led capacitive led buttons as per https://github.com/retiredtab/andro...mmit/83551570e4627a0e353e358787f83aa65484b528
3. Incorporates May 5th security patches as per https://review.lineageos.org/q/topic:R_asb_2022-05
4. If you are upgrading from the April 10 build, you may dirty flash the May 10 build. If you are NOT coming from the April 10th, 2022 build, you MUST BACKUP your data because YOU MUST wipe dalvik/cache, cache, system, data and internal storage partitions in TWRP and FORMAT DATA. You cannot dirty flash at all. See FAQ Q11.
@retiredtab just flashed it onto 20220410.
1st try very dirty (not wiping anything) resulting in bootloop.
2nd flash (after wiping system+caches) of ROM, Bitgapps28-arm, Magisk23 made it start.
Magisk had of course to patch boot.img again.
Thx very much.
Due to a post in the T710 regarding gapps, I will be removing opengapps from the FAQ because for several months now (starting around Oct 2021), the opengapps project has been releasing UNTESTED builds that results in bootloops or non working gapps services. Despite numerous requests/posts from the community to slow down the releases and actually TEST THEM BEFORE release, the latest May 3, 2022 shows there is still room for improvement.
This thread in the opengapps forum is just the latest example. Details of UNTESTED builds are also in the same megathread below.

This would be a good time for user to do their own research on which gapps is best for them or use NONE at all. I use Aurora Store myself.
Just a reminder that the builds we release are TESTED and verified to have all the functionality as listed in post #1.
T710 thread post #8, #9 and #10.
https://forum.xda-developers.com/t/...neageos-18-1-for-sm-t710-may-12-2022.4430339/
I wanted to express my sincere thanks to @retiredtab and @Ipedia for your work on the ROMs for the T710 and T810. I have both devices and had previously used the @ripee versions in thread (2) [ROM][UNOFFICIAL][11] LineageOS 18.1 [T710][T715][T715Y][T810][T815][T815Y] | XDA Forums (xda-developers.com). But that 18.1 version had some noticeable bugs and wasn’t being maintained.
Thanks to @bmwdroid ’s April 15 post directing us to this forum, I have been experimenting with this ROM since then on both the T710 and the T810. Based on my pretty heavy usage, I can declare both to be excellent. Most notably, the WiFi is rock solid. The T810 and the T710 (especially) are outstanding hardware, and being able to run Android 11 is a huge boost in the device’s intrinsic value.
I have experienced a couple of random BSOD-equivalent crashes over the past month, but the tablet always immediately restarted. I am going to try and learn how to provide the necessary to the developers so, if it happens again, they can have the necessary evidence. Since I am a decent techie, but not a developer, I decided to write up the complete upgrade procedure I followed so others who come to this forum may benefit. See my next post.
PS: I put this post on both the T710 and the T810 threads since I have both devices.
Tab S2 T710 and T810 Upgrade Procedure Using LineageOS 18.1 ROM by retiredtab
These installation instructions work for both Tab S2 T710 and T810. I have both devices and have tested on both. I am a Windows guy, so these instructions assume a Windows PC. I am a lifelong techie guy and an Android enthusiast. But I am not developer, so these instructions should work for any competent newbie who is a decent techie, but I realize there may be alternative approaches for those who have deeper tech knowledge than me.
Step 1 – Preparation
Update your Tab S2 to the latest stock software.
Install a micro-SD card into your Tab S2.
Enable Developer Options – tap Build Number seven times.
In Developer Options, turn on USB debugging.
Connect your TGab S2 to your PC via USB and download onto the micro-SD card three files:
Retiredtab’s latest Lineage 18.1 ROM from lpedia-sf - Browse /gts28wifi at SourceForge.net (T710) or retiredtab - Browse /SM-T810/18.1 at SourceForge.net (T810)
open_gapps-arm-11.0-pico-20220215.zip from The Open GApps Project
Magisk-v24.3.apk from Release Magisk v24.3 · topjohnwu/Magisk · GitHub
Download to your PC TWRP_3.5.2_9_SM-T710_20210719_Unofficial.tar from retiredtab - Browse /SM-T710/TWRP at SourceForge.net (T710) or twrp-3.5.2_9-0-gts210wifi.img.tar from Download TWRP for gts210wifi (T810)
Download to your PC Odin, from https://technastic.com/wp-content/uploads/2020/02/Odin3_v3.14.4.zip, and extract the zip.
Comments:
I saw retiredtab’s comments about OpenGApps quality. However, this version works well for me. I had previously tried the latest MindTheGapps (which hung) and BiTGapps (which doesn’t include the Google restore functionality that I use.)
Magisk is optional if you want/like root. I do!
Step 2 – Install TWRP Recovery
Power off your Tab S2.
Launch Odin on your PC and press OK.
Power up your Tab S2 into Download mode by holding down Home+VolDown+Power.
Then at the Warning screen hit VolUp.
Connect your Tab S2 via USB to your PC, and you should see Added!! in Odin.
Click AP in Odin and select the downloaded TWRP.
In Odin Options, uncheck Auto Reboot.
Click Log tab again.
Click Start in Odin.
Installed TWRP only takes a couple of seconds.
You will see progress in the Log, and Pass at the top of Odin when done.
Step 3 – First boot into TWRP.
This part is tricky!
Power down your Tab S2 by holding down VolDown+VolUp+Power.
IMMEDIATELY the screen goes blank, hold down Home+VolUp+Power.
Keep holding down until you see the TWRP home page.
If you end up booting into Android rather than TWRP then you will have to repeat steps 2 and 3 again.
Step 4 – Backup your stock ROM
In TWRP, select Backup, Select Storage to choose your micro-SD card, check all the boxes, and then swipe Backup.
Step 5 – Install ROM and GApps.
In TWRP, select Wipe, then Advanced Wipe.
Select all partitions except Micro SD Card.
Swipe to Wipe.
Back, Back again, then Format Data
Type yes, and hit check.
Back, Back, Back, and select Install.
Select your micro-SD storage.
Select the Lineage-18.1 ROM.
Add more Zips, and select open_gapps.
Swipe to confirm Flash.
Installation took about 3 minutes.
Wipe Cache/Dalvik, and Swipe to Wipe
Reboot System
Step 6 – Build your Android 11 Tab S2
First boot into Lineage was less than a minute, and then the Lineage boot animation took less than 2 minutes before “Hello” appeared.
On each build I’ve done I see “Speech services by Google keeps stopping” error once Hello appeared.
I assume this is one of the known OpenGApps bugs.
Clicking Close App makes it go away, and later Google replaces the module anyway.
Set up your Android device per your preference. I have loads of Apps so it takes me a long time. If you are less of a pack-rat, it shouldn’t take long!
At the end of the initialization process, be sure not to choose the Replace Lineage recovery option, otherwise TWRP goes away.
I have found that, by not installing Magisk initially, Google restores all my Apps, including the sensitive ones such as Peacock, Netflix, Disney+, etc. And when I check Google Play/Settings and scroll to the bottom, I see “Device is certified”.
I recommend leaving tablet completely alone until Google has finished its “Copy Apps and Data” from my other tablet. When I get impatient and fiddle around as it’s copying I’ve seen crashes.
Once all copying is done, do your unique Android setup. My go-to Android settings are:
Nova Prime Launcher (actually, gets selected during the copy process, but I load my layout from backup at this time)
Microsoft Swiftkey
Default USB = File Transfer
Window/Transition/Animator Scale all set to Animation Off
Screen timeout 30 minutes, and screen saver Clock
Battery %age next to icon
FX File Explorer
Microsoft Edge as default browser (with AdBlock enabled and Google as search and sync to my PC)
Raindrop, for all my bookmarks
Advanced restart menu (to allow reboot into TWRP).
Step 7 – Make Root
Restart Tab S2 into TWRP.
In TWRP, Install Magisk-v24.3.apk.
Reboot System
In Android install Magisk-v24.3.apk.
Open Magisk and select zygisk in settings.
Restart again.
You now have root. I test by enabling root in FX File Explorer and granting root.
Step 8 – All done!
I do a final and full TWRP backup once the device is solid.
Note:
I found the fingerprint reader sometimes works to unlock the Tab S2. Per other discussions on this thread, looks like I got lucky!

Thanks. I updated FAQ to point to post #16 for newbies.
Hi just a question regarding Q5
A5. You MUST use TWRP 3.5.2_9.
Is there a reason for this! I'm only asking because I have 3.6.0.9-0 installed so just wondered why its a must.
Edit - ignore the message above I didn't see post 9 when reading this on my tablet but do now I am on PC.
Had this running now for the last 5 hours, everything seems to be fine but I'm seeing very slow WiFi speeds. Coming straight from (lineage-18.1-20211103-UNOFFICIAL-gts210wifi) where I was getting a constant speed over 330mb I'm now only getting 110 dropping down to 70 at best.

@retiredtab Maybe just a wild guess, but might this commit be related? In my understanding argosd is a daemon that controls the CPU governor so that CPU performance can be adopted to network bandwith requirements. Shouldn't that be activated for Wifi models as well?
LineageOS 19.1 UNOFFICIAL for 2015 Samsung Galaxy Tab S2 SM-T810 ONLYModel: SM-T810 (wifi) - gts210wifi - 9.7" screen, Exynos 5433 SoC, no LTE
This is the ONLY model that the ROM will work on.
There is NO ROM for the T715 or T815 in this thread. Questions about T715 or T815 will be completely IGNORED.
You MUST READ posts 1-4 (about 10 minute read) before deciding to install this rom. If you think this is an unreasonable request, then stop reading now and find another rom. Thank you.
DISCLAIMER
I am not responsible for lost data, identity theft, lost money, security vulnerabilities, bricked devices or any other hardware or software malfunctions that comes as a result of flashing this rom.
All involved in bringing this build to you are working voluntarily on it in very limited spare time, and their other life commitments have much higher priority. Don't expect a prompt, or even any, response to questions and bug reports.
Before attempting to install this ROM
1. Ask yourself: would bricking your device be a disaster for you? If yes, don't try this ROM! It can't be guaranteed stable and reliable enough to depend on for daily use.
2. BACKUP YOUR DATA AND EXISTING ROM. Be prepared for a complete restore if anything goes wrong.
3. RESEARCH adb, fastboot, Odin/heimdall, and TWRP and how to use them, if not already familiar with these.
What works
1. bluetooth
2. wifi
3. brightness
4. external audio
5. GPS
6. audio through headphone jack
7. audio over bluetooth
8. selinux enforcing
9. DRM level 3 (SD definition)
10. deep sleep
11. camera
What doesn't work
1. fingerprint is completely removed in 19.1. When I tested it in March 2022, it wasn't compatible with keystore2 and as I wrote in post 1891 at
https://forum.xda-developers.com/t/...t810-t815-t815y.3879302/page-95#post-85533725
it never worked properly after deep sleep. If you need fingerpint to work, stay with stock Samsung rom.
2. DRM level 1 (no HD definition). There's more detail in post 1891 above. I will not be trying to achieve level 1 for HD definition. If you need HD definition for your $treaming media, stay with stock Samsung rom.
3. workaround to disable scoped storage. In 18.1 there was a workaround to disable scoped storage, but that no longer works in 19.1. So if you have a lot of apps or data on an external microsd, the performance may be severely degraded.
4. If you charge the device while it's powered off and then want to power it on, you MUST wait at least 30 seconds AFTER disconnecting the charger cable before pressing the power button otherwise you might run into strange boot problems.
5. keyboard bug workaround. When prompted to enter something like a Bluetooth pin or text based password, sometimes the keyboard is not shown on the screen or off screen. The workaround is to goto settings, system, languages & input, on-screen keyboard, Android Keyboard (AOSP), appearance & layout, theme and choose "Material - follow system settings".
This keyboard bug is a LineageOS bug as per
https://review.lineageos.org/c/LineageOS/android_packages_inputmethods_LatinIME/+/325438
6. There has no been no fix for the “Connected to device. Can’t provide internet”. DO NOT ASK when this will be fixed. If/when it is fixed, it will be announced public in this thread.
If this is problem for you, go back to 18.1. In addition, the problem might be a memory leak so the less apps you have installed (like gapps), the better. I rarely see this problem as my setup is very simplistic. I just have Brave browser, Newpipe and Aurora Store.
7. Possibly other features that I haven't tested or do not use.

Frequently Asked Questions. You MUST READ this before posting any questions. Thank you.
QuestionAnswerQ1. Can I build this ROM for myself? Where are the source and kernel source files?A1. Yes, you can. The source files are listed below.
Kernel
https://github.com/retiredtab/android_kernel_samsung_universal5433-selinux
Device Tree
https://github.com/retiredtab/android_device_samsung_gts2-common-selinux
https://github.com/retiredtab/android_device_samsung_gts210wifi
Vendor
https://github.com/retiredtab/proprietary_vendor_samsung-selinux
The build manifest and instructions on how to compile from source are at
https://github.com/retiredtab/LineageOS-build-manifests
The other patch required for tcp/ip is at https://github.com/DerpFest-11/pack...mmit/22fd53a977eeaf4e36be7bf6358ecf2c2737fa5eQ2. Is this ROM suitable as a daily driver?A2. It might be, depending on your requirements. You would need to try it yourself, with your preferred apps, to see if suits your purposes. I've been using it myself since July 1, 2022 with no major issues.Q3. What do I do if my app xyz doesn't work?A3. I can't help diagnose problems with random apps I know nothing about. If the app is critically important to you and it doesn't work on this ROM, go back to a ROM where it did work.Q4. Why is this ROM laggy and/or buggy?A4. The device will be noticeably slower if you're using any Gapps package. Consider going gapps-free. A lot of apps will work without Google's services, or there exist alternatives that will. Check out F-Droid, Aurora Store, NewPipe, etc.Q5. What TWRP should I use?A5. You MUST use TWRP 3.6.2_9. Get it from
https://dl.twrp.me/gts210wifi/Q6. Why should I use this ROM?A6. You don't have to! If you don't like it, go back to your old ROM.Q7. Will you offer monthly updates with security patches?A7. We plan to do so. We will try to update the ROM with the monthly security patches after LineageOS has released them, free time permitting. Each monthly build will be tested to make sure all the "What works" functionality listed in post #1 still works, before it's made available (which might in some cases delay the release).Q8. I'm a newbie. Can you provide step by step instructions?A8. We simply don't have the time to do this, but there are lots of tutorials, videos, etc online showing how to flash custom ROMs and how to deal with common problems. Newbie questions are also accepted in the XDA General Questions and Answers forum.
Having said that pflyaz has kindly provided instructions in post #7.Q9. Can I report a bug with respect to the ROM?A9. Yes, but you need to supply the following information. If you don't, I won't look at it.
Provide an adb logcat of the problem, and if possible describe how to reproduce it. Note that I can't help if it involves downloading any app I don't already use that requires payment or creating a userid/password.
To get a logcat, open a terminal window on your PC, connect your device to it via USB, and do this:
Bash:
# clear the logcat first
adb logcat -c
# start logcat trace
adb logcat > problem.txt
# reproduce problem
# wait until problem has occurred,
# then stop trace by hitting ctrl-c then zip the problem.txt file
# before uploading it.
Q10. How long will you build 19.1 for this device?A10. For now, 19.1 will be built for all of 2022. After that, we will make a decision depending on a number of factors.Q11. Do I need to erase everything and format my data before installing this ROM for the first time?A11. If you're coming from stock Samsung Android, or an earlier version of LineageOS, or a different custom ROM, you MUST 'clean flash': boot to TWRP recovery, wipe system, data, dalvik/art cache, and cache partitions, then Format Data, then install this ROM.
If you don't do this you're likely to run into problems, such as getting stuck at the boot animation for more than 5 minutes.Q12. What Gapps should I use?A12. Your choice! There are several well-known Gapps packages, such as NikGapps, BiTGapps, OpenGapps, and MindTheGapps. Do your own research as to what is the most reliable gapps option for you. As a courtesy to gapps users, I opened a thread at
https://forum.xda-developers.com/t/...on-for-19-1-roms-sm-t710-and-sm-t810.4480041/
for you to discuss gapps. Do not discuss gapps in this thread. Thank you.
You could also consider Google alternatives, such as Aurora Store, which mirrors the Google Play Store apps but doesn't need any Google services itself. Many Play Store apps do not actually depend on Google services.
If you are going to install any Gapps package, follow the installation instructions given for that particular package.Q13. I'm having problems with Gapps. Can you tell me why it's not working?A13. I can't answer any questions about Gapps, because I don't use them. Ask your questions on the XDA thread for the Gapps package you're using.Q14. Why isn't my post answered?A14. There are several possible reasons: the question is answered in the FAQ (in which case it will be ignored completely); or it involves apps or operating systems that I don't use; or it's about Gapps, which I don't use; or I simply have not had time to answer any questions.Q15. What speed up/optimization tips do you suggest?A15. These steps can make a big difference to performance:
Turn off animations. Go to Settings > System > Developer options, scroll down to the Drawing section, and set Window, Transition and Animator scale all to "Animation off".
Don't install Gapps unless you depend on something that only Google is providing. Use Aurora Store to get your preferred Play Store apps - they will all be available on Aurora Store. You can choose to access this anonymously or use a Google account.
Don't run more than two apps at the same time. You can probably listen to music in the background and use a web browser at the same time.
Use a web browser with built-in adblock and privacy features, such as Brave.
Use NewPipe to watch your streaming content. It has built in adblock so you don't have to watch forced ads.
Look for apps that are open source, ad-free and lightweight.
Q16. Does this ROM support Magisk so I can root my device?A16. Magisk works with this ROM as reported by beta testsers, but that could change with any revision and changes by Google. However I don't use it myself and can't help with any related issues. Direct any questions about Magisk to the XDA Magisk forum.Q17. Will this ROM ever become official?A17. With 19.1, legacy devices like ours will NEVER be official due to lack of ebpf support. See https://lineageos.org/Changelog-26/Q18. What is the difference between this ROM and others?A18. This ROM tries to be pure LineageOS with little or no modification. Other ROMs may come with a different UI, different bundled apps, etc.Q19. Will there be any major 19.1 code modifications in the future?A19. There may be some major modifications along with some slight tweaking to the SEpolicy, small bug fixes and minor code cleanup, but all the hard work - getting the rom up and running, and fixing all the major bugs - has been done.Q20. Why did you fork the trees?A20. I wanted my own private branch where I could make changes that would only affect my own personal builds.Q21. Can you build a variant of this device? For example, a LTE or S-pen version?A21. I cannot and will not try to build for a variant device if I don't physically have that device. I have to be able to boot and test it myself, and there's no guarantee that I can get those variant features working.Q22. Can I load this ROM on a variant device like LTE or S-pen version?A22. This ROM is for the device explicitly listed and will only work on that device. Do not try to install it on any other device.
ONLY if you are an advanced user and understand TWRP, adb, odin, heimdall, etc, you could try loading it on a LTE or S-pen variant by modifying the updater-script, but be warned: there are likely to be problems, including a bricked device, bootloops, or the ROM not being able to support the functionality of LTE/S-pen.Q23. Does this ROM have any wifi connection issues?A23. This ROM's wifi has been stable on the specified device ever since lpedia and I determined the root cause of the wifi problems back in July 2021 and re-installed the original S2 network 'blobs' with LOS 17.1.Q24. Is this ROM secure so I can do financial transactions?A24. Although Android monthly security patches do improve general security, this ROM's outdated kernel and old proprietary vendor blobs/drivers will NEVER get updates of any kind, and could have significant security holes.
In addition, although the ROM is SElinux enforcing, there's a good chance that the rules written (about 800+ lines of code) have some errors.
If the device is rooted, this would further weaken the security.
With this information, it's up to you to make an informed decision about whether you trust this ROM to be secure enough for your financial transactions.Q25. How do I turn off the taskbar at the bottom of the screen?A25. Goto settings, system, buttons and disable taskbar.Q26. Okay, I understand the consequences and willing to take the risks outlined, now where can I find the ALPHA rom?A26. Downloads are at https://sourceforge.net/projects/retiredtab/files/SM-T810/19.1/
NOTE: All builds that I upload have been personally tested on my device to boot and function as described in post #1. Having said that, there's still a chance it won't work on your device due to human error, your configuration, your apps, etc. If it won't boot, always start with a complete wipe of everything and format your data in TWRP. This is known has a clean install. Backup your data before a clean install.

@retiredtab imho you can add back and front camera to the "What works" list.
I recommend to use OpenCamera but built in one works as well.

Tab S2 T810 Upgrade Procedure for the LineageOS 19.1 ROM by retiredtab
These installation instructions work for both Tab S2 T710 and T810, starting from a device running stock Android 7.0. I have both devices and have tested the procedure on both. I am a Windows guy, so these instructions assume a Windows PC. I am a lifelong techie guy and an Android enthusiast. My current “production” devices are Samsung S22 Ultra and Samsung Tab S7, but I do love the size and performance of the Tab S2 T710 so am extremely happy that @retiredtab and @lpedia have been successful at making Lineage 19.1 run on the Tab S2. But I am not developer, so these instructions will work for any competent newbie who’s looking for LOS 19.1 on their Tab S2 tablet. I do realize there may be alternative approaches for those who have deeper Android tech knowledge than me, but this procedure does work every time.
Step 1 – Preparation
Update your Tab S2 to the latest stock software.
Install a micro-SD card into your Tab S2.
Enable Developer Options – tap Build Number seven times.
In Developer Options, turn on USB debugging.
Connect your Tab S2 to your PC via USB and download onto the micro-SD card three files:
Retiredtab’s latest Lineage 19.1 ROM from lpedia-sf - Browse /gts28wifi-19.1 at SourceForge.net (T710) or retiredtab - Browse /SM-T810/19.1 at SourceForge.net (T810)
NikGapps-core-arm64-12.1-20220709-signed.zip from https://sourceforge.net/projects/nikgapps/files/Releases/NikGapps-SL/
Magisk-v25.2.apk from https://github.com/topjohnwu/Magisk/releases
Magisk is optional if you want/like root.
Download to your PC TWRP_3.5.2_9_SM-T710_20210719_Unofficial.tar from retiredtab - Browse /SM-T710/TWRP at SourceForge.net (T710) or twrp-3.5.2_9-0-gts210wifi.img.tar from Download TWRP for gts210wifi (T810)
Download to your PC Odin, from https://technastic.com/wp-content/uploads/2020/02/Odin3_v3.14.4.zip, and extract the zip.
Step 2 – Install TWRP Recovery
Power off your Tab S2.
Launch Odin on your PC and press OK.
Power up your Tab S2 into Download mode by holding down Home+VolDown+Power.
Then at the Warning screen hit VolUp.
Connect your Tab S2 via USB to your PC, and you should see Added!! in Odin.
Click AP in Odin and select the downloaded TWRP.
In Odin Options, uncheck Auto Reboot.
Click Log tab again.
Click Start in Odin.
Installing TWRP only takes a couple of seconds.
You will see progress in the Log, and Pass at the top of Odin when done.
Step 3 – First boot into TWRP
This part is tricky!
Power down your Tab S2 by holding down VolDown+VolUp+Power.
IMMEDIATELY the screen goes blank, hold down Home+VolUp+Power.
Keep holding down until you see the TWRP home page.
If you end up booting into Android rather than TWRP then you will have to repeat Step 2 and Step 3 again.
Step 4 – Backup your stock ROM
In TWRP, select Backup, Select Storage to choose your micro-SD card, check all the partition boxes, and then swipe Backup.
Confirm your backup is good
In TWRP, select Wipe, then Advanced Wipe.
Select all partitions except Micro SD Card (and USB OTG).
Swipe to Wipe.
Back, Back again, then Format Data
Type yes, and tap check.
Back, Back, Back, and select Restore.
Select Micro SD card and your backup.
Restore all partitions and allow restore to complete.
Reboot to System, and confirm you are back to stock.
Step 5 – Install ROM and NikGApps
In TWRP, select Wipe, then Advanced Wipe.
Select all partitions except Micro SD Card (and USB OTG).
Swipe to Wipe.
Back, Back again, then Format Data
Type yes, and tap check.
Back, Back, Back, and select Install.
Select your micro-SD storage.
Select the Lineage-19.1 ROM.
Add more Zips, and select nikgapps.
Swipe to confirm Flash.
Install takes about 3 minutes.
Wipe Cache/Dalvik, and Swipe to Wipe.
Reboot System.
Step 6 – Build your Android 12 Tab S2
First boot into Lineage is less than a minute, and then the Lineage boot animation takes less than 1 minute before “Welcome to LineageOS” appears.
At the end of the initialization process, be sure not to choose the Replace Lineage Recovery option, otherwise TWRP goes away.
Set up your Android device per your preference. I am a mainstream Google/Google Play Apps user, and I have loads of Apps, so it takes me a long time to install my Apps and set the tablet up for daily use. If you are less of a pack-rat, it shouldn’t take long!
I have found that, by not installing Magisk initially, I can restore all my Apps, including the sensitive ones such as Peacock, Netflix, Disney+, etc. All Apps run normally, and when I check Google Play/Settings and scroll to the bottom, I see “Device is certified”.
I recommend leaving tablet completely alone during the initial Apps and Data restore process. When I get impatient and fiddle around as it’s copying I’ve seen crashes.
Once all copying is done, do your unique Android setup. My go-to Android settings are:
Nova Prime Launcher (actually, gets selected during the initialization process, but I load my layout from backup at this time)
Microsoft Swiftkey
Screen timeout 30 minutes, and screen saver Clock
Dark theme off
Disable taskbar.
Plain dark blue wallpaper
Touch, screen locking, and charging sounds off
Battery %age next to icon
Default USB = File Transfer
Developer Options enabled, and USB and Rooted debugging selected
Window/Transition/Animator Scale all set to Animation Off
FX File Explorer
Microsoft Edge as default browser (with AdBlock enabled and Google as search and sync to my PC)
Raindrop, for all my cross-platform/device bookmarks
Advanced restart menu (to allow reboot into TWRP).
Step 7 – Make Root – Optional
Restart Tab S2 into TWRP.
In TWRP, install Magisk-v25.2.apk.
Reboot System
In Android install Magisk-v25.2.apk.
Open Magisk and select zygisk in settings.
Restart again.
You now have root. I test by enabling root in FX File Explorer and granting root.
Step 8 – All done! Enjoy!
I do a final and full TWRP backup once the device is solid on Lineage 19.1.

No Keyboard at first boot -fix:
This is an excellent ROM !! So thank you for these detailed instructions and links.
I just want to add my experience with a small issue of no keyboard showing up. I fixed this here: https://forum.xda-developers.com/t/...oms-sm-t710-and-sm-t810.4480041/post-87316675
With that fix, this ROM runs without any hitch. I am now fully running this ROM and all apps and settings like I want.
Don't use anything above Basic in NikGapps (see my fix post). Above that one of the Gapp kept crashing and the tablet did not go through set up but stuck on "Tablet starting........"
Once Gboard is working, you can then set up and download any other keyboard you want.

LineageOS 19.1 UNOFFICIAL for 2015 Samsung Galaxy Tab S2 SM-T810 ONLYModel: SM-T810 (wifi) - gts210wifi - 9.7" screen, Exynos 5433 SoC, no LTE
This is the ONLY model that the ROM will work on.
There is NO ROM for the T715 or T815 in this thread. Questions about T715 or T815 will be completely IGNORED.
You MUST READ posts 1-4 (about 10 minute read) before deciding to install this rom. If you think this is an unreasonable request, then stop reading now and find another rom. Thank you.
DISCLAIMER
I am not responsible for lost data, identity theft, lost money, security vulnerabilities, bricked devices or any other hardware or software malfunctions that comes as a result of flashing this rom.
All involved in bringing this build to you are working voluntarily on it in very limited spare time, and their other life commitments have much higher priority. Don't expect a prompt, or even any, response to questions and bug reports.
Before attempting to install this ROM
1. Ask yourself: would bricking your device be a disaster for you? If yes, don't try this ROM! It can't be guaranteed stable and reliable enough to depend on for daily use.
2. BACKUP YOUR DATA AND EXISTING ROM. Be prepared for a complete restore if anything goes wrong.
3. RESEARCH adb, fastboot, Odin/heimdall, and TWRP and how to use them, if not already familiar with these.
What works
1. bluetooth
2. wifi
3. brightness
4. external audio
5. GPS
6. audio through headphone jack
7. audio over bluetooth
8. selinux enforcing
9. DRM level 3 (SD definition)
10. deep sleep
11. camera
What doesn't work
1. fingerprint is completely removed in 19.1. When I tested it in March 2022, it wasn't compatible with keystore2 and as I wrote in post 1891 at
https://forum.xda-developers.com/t/...t810-t815-t815y.3879302/page-95#post-85533725
it never worked properly after deep sleep. If you need fingerpint to work, stay with stock Samsung rom.
2. DRM level 1 (no HD definition). There's more detail in post 1891 above. I will not be trying to achieve level 1 for HD definition. If you need HD definition for your $treaming media, stay with stock Samsung rom.
3. workaround to disable scoped storage. In 18.1 there was a workaround to disable scoped storage, but that no longer works in 19.1. So if you have a lot of apps or data on an external microsd, the performance may be severely degraded.
4. If you charge the device while it's powered off and then want to power it on, you MUST wait at least 30 seconds AFTER disconnecting the charger cable before pressing the power button otherwise you might run into strange boot problems.
5. keyboard bug workaround. When prompted to enter something like a Bluetooth pin, sometimes the keyboard is not shown on the screen or off screen. The workaround is to bring up the built in browser, touch the url panel where the http address is and then press the number key when the keyboard pops up. Leave this browser open like that, then press the home button and try your Bluetooth pairing again.
This keyboard bug is a LineageOS bug as per
https://review.lineageos.org/c/LineageOS/android_packages_inputmethods_LatinIME/+/325438
6. Possibly other features that I haven't tested or do not use.

That's been reported already, but "fast charging" doesn't work anyway.
At least not on my device.
5.23V and max. 1.2A (getting down to 0.9A reaching full capacity)

This "fast charge" commit was introduced April 22, 2021 in 17.1.
https://github.com/universal5433/an...mmit/c70731b9a69523eaa30c1d0c12d26938e4a4c373
I never really ran 17.1 other than to solve the wifi and random reboot problems so I never tested it to see if it worked or not.
However, I don't think it ever worked in 18.1 when I looked at it and definitely not in 19.1. I'll put a note in post #1 to say it doesn't work. When I have time, I'll do some more research and see what it's supposed to do. If it is not meant for our device, I'll remove it from the code in a future update.
Let's also remember that the S2 was released in 2015 and I believe it came with a 2A 10W charger. In this post,
https://forum.xda-developers.com/t/...t810-aug-10-2022.4430349/page-3#post-87309527
I wrote that it took about 3 hours to charge to full from 12% battery remaining.
With a 5870mAh battery in the T810 and assuming perfect charging conditions with no loss due to heat, cable resistance, etc, then (3 hours x 2000mA = 6000mAh) is enough to charge a 5870mAh battery to 100%.
Today's definition of "fast charge" with flagship devices and > 10W chargers is probably getting 60% charge in 15 minutes.
I don't purposely feel the tablet's battery for heat, but I do notice that the ac/usb adapter does get quite warm when it's charging. However, my Apple Ipad ac/usb adpater also gets probably a little bit warmer than the Samsung ac/usb adapter. So if it happens on the stock Apple Ipad, then it likely normal for the Samsung as well.
It's not hot enough to burn your fingers when charging, but I do notice it especially when the ambient temperature is warmer too like during hot summer days. On those days, I try to charge the devices during night time when it's cooler and I never leave them charging if I have to leave the house.
One other thought is that our devices are 7 years old with a 7 year old battery. Depending on how much you have used the device, the battery could be getting to near end of life and that might explain why your battery is getting hot when charging.
I suggest you download devcheck by flar2. It's an excellent ad-free program that helps with developing and testing.
https://play.google.com/store/search?q=devcheck&c=apps&hl=en&gl=US
It has a battery tab which shows the current temperature of the battery, charging or discharging, health, voltage, etc. Maybe you can use it to monitor the battery temperature and report back what it is? If you have an external usb power/amp monitor, that would also help show you how much the device is drawing. Something like this
https://www.electroschematics.com/wp-content/uploads/2019/01/1-USB-Power-Monitor-550x550.jpg
With all the crap features that newer Android versions keep coming out with, it would help everyone if there was a built in battery lifecycle reader that showed how many cycles your battery has gone through and when your battery needs replacing (assuming manufacturers don't glue the crap out their devices).

Thanks!
I realized it was getting hot because I was browsing while it was charging. If I stopped and just did reading, it cooled off. The right side of the screen was getting hot enough otherwise, and I think there is where battery is?
Overnight on silent charge it charged and is fine. I'll leave it at that.
I confirmed with ananjaser1211 that "fast charging" is not supported by the S2 devices. Our S2 devices charge at the normal rate 2A (or less) over 5V. So this code and it's menu option will be removed in the next build.
I will give more details when I write the release notes and it will also be documented in the github commit.
New build called lineage-19.1-20220911-UNOFFICIAL-gts210wifi.zip
NOTE: All builds that I upload have been personally tested on my device to boot and function as described in post #1. Having said that, there's still a chance it won't work on your device due to human error, your configuration, your apps, etc. If it won't boot, always start with a complete wipe of everything and format your data in TWRP. This is known has a clean install. Backup your data before a clean install.
19.1 has been my daily driver since July 2022.
Sept 11, 2022 release notes
1. YOU MUST read posts 1-4 if you haven't already.
2. Sept 5 security patches as per https://review.lineageos.org/q/topic:S_asb_2022-09
3. Removed settings menu option for fast charging. S2 tablet devices do not support this.

Thx again
Fantastic and totally not count on: a smooth android 12 rom on my tab s2!! All smooth so far. Wifi download is just fine (and stable ). And keyboard present.
Coming from Ripees L18. Already had the right TWRP. Wiped all (except ext. storage) installed rom and NikGapps-core-arm64. After boot also magisk 25.2.
Thanks a lot!
Like everyone else has said this is a nice ROM running so smooth.
Only 1 problem that I need to stop the backup option I need to disabled I don't really use it. I try to change it but it won't let me it keeps reverting back to Seedvault and I don't use it.

I fixed this by explicitly changing my backup provider to my Google account during the initial setup. I believe this is a LineageOS "feature", but I can't for the life of me understand why any backup provider needs me to enter and remember twenty words just to do a backup - it's crazy! This is a case of Lineage folks way over-engineering something that should be simple. I suggest trying to change your backup provider in settings as a first step. But I have a vague memory from an early testing cycle that I somehow got Seedvault running and I couldn't stop it. The only fix was to completely rebuild the ROM from scratch and then do the Google backup setup early before Seedvault jumped in. Good luck!
LineageOS 19.1 UNOFFICIAL for 2015 Samsung Galaxy Tab S2 SM-T710 ONLYModel: SM-T710 (wifi) - gts28wifi - 8" screen, Exynos 5433 SoC, no LTE
This is the ONLY model that the ROM will work on.
There is NO ROM for the T715 or T815 in this thread. Questions about T715 or T815 will be completely IGNORED.
You MUST READ posts 1-4 (about 10 minute read) before deciding to install this rom. If you think this is an unreasonable request, then stop reading now and find another rom. Thank you.
DISCLAIMER
I am not responsible for lost data, identity theft, lost money, security vulnerabilities, bricked devices or any other hardware or software malfunctions that comes as a result of flashing this rom.
All involved in bringing this build to you are working voluntarily on it in very limited spare time, and their other life commitments have much higher priority. Don't expect a prompt, or even any, response to questions and bug reports.
Before attempting to install this ROM
1. Ask yourself: would bricking your device be a disaster for you? If yes, don't try this ROM! It can't be guaranteed stable and reliable enough to depend on for daily use.
2. BACKUP YOUR DATA AND EXISTING ROM. Be prepared for a complete restore if anything goes wrong.
3. RESEARCH adb, fastboot, Odin/heimdall, and TWRP and how to use them, if not already familiar with these.
What works
1. bluetooth
2. wifi
3. brightness
4. external audio
5. GPS
6. audio through headphone jack
7. audio over bluetooth
8. selinux enforcing
9. DRM level 3 (SD definition)
10. deep sleep
11. camera
1. fingerprint is completely removed in 19.1. When I tested it in March 2022, it wasn't compatible with keystore2 and as I wrote in post 1891 at
https://forum.xda-developers.com/t/...t810-t815-t815y.3879302/page-95#post-85533725
it never worked properly after deep sleep. If you need fingerpint to work, stay with stock Samsung rom.
2. DRM level 1 (no HD definition). There's more detail in post 1891 above. I will not be trying to achieve level 1 for HD definition. If you need HD definition for your $treaming media, stay with stock Samsung rom.
3. workaround to disable scoped storage. In 18.1 there was a workaround to disable scoped storage, but that no longer works in 19.1. So if you have a lot of apps or data on an external microsd, the performance may be severely degraded.
4. If you charge the device while it's powered off and then want to power it on, you MUST wait at least 30 seconds AFTER disconnecting the charger cable before pressing the power button otherwise you might run into strange boot problems.
5. keyboard bug workaround. When prompted to enter something like a Bluetooth pin or text based password, sometimes the keyboard is not shown on the screen or off screen. The workaround is to goto settings, system, languages & input, on-screen keyboard, Android Keyboard (AOSP), appearance & layout, theme and choose "Material - follow system settings".
This keyboard bug is a LineageOS bug as per
https://review.lineageos.org/c/LineageOS/android_packages_inputmethods_LatinIME/+/325438
6. Possibly other features that I haven't tested or do not use.

Frequently Asked Questions. You MUST READ this before posting any questions. Thank you.
QuestionAnswerQ1. Can I build this ROM for myself? Where are the source and kernel source files?A1. Yes, you can. The source files are listed below.
Kernel
https://github.com/retiredtab/android_kernel_samsung_universal5433-selinux
Device Tree
https://github.com/retiredtab/android_device_samsung_gts2-common-selinux
https://github.com/retiredtab/android_device_samsung_gts28wifi
Vendor
https://github.com/retiredtab/proprietary_vendor_samsung-selinux
The build manifest and instructions on how to compile from source are at
https://github.com/retiredtab/LineageOS-build-manifests
The other patch required for tcp/ip is at https://github.com/DerpFest-11/pack...mmit/22fd53a977eeaf4e36be7bf6358ecf2c2737fa5eQ2. Is this ROM suitable as a daily driver?A2. It might be, depending on your requirements. You would need to try it yourself, with your preferred apps, to see if suits your purposes. I've been using it myself since mid April, 2022 with no major issues.Q3. What do I do if my app xyz doesn't work?A3. I can't help diagnose problems with random apps I know nothing about. If the app is critically important to you and it doesn't work on this ROM, go back to a ROM where it did work.Q4. Why is this ROM laggy and/or buggy?A4. The device will be noticeably slower if you're using any Gapps package. Consider going gapps-free. A lot of apps will work without Google's services, or there exist alternatives that will. Check out F-Droid, Aurora Store, NewPipe, etc.Q5. What TWRP should I use?A5. You MUST use TWRP 3.5.2_9. Get it from https://github.com/retiredtab/android_device_samsung_gts28wifiQ6. Why should I use this ROM?A6. You don't have to! If you don't like it, go back to your old ROM.Q7. Will you offer monthly updates with security patches?A7. We plan to do so. We will try to update the ROM with the monthly security patches after LineageOS has released them, free time permitting. Each monthly build will be tested to make sure all the "What works" functionality listed in post #1 still works, before it's made available (which might in some cases delay the release).Q8. I'm a newbie. Can you provide step by step instructions?A8. We simply don't have the time to do this, but there are lots of tutorials, videos, etc online showing how to flash custom ROMs and how to deal with common problems. Newbie questions are also accepted in the XDA General Questions and Answers forum.
Having said that pflyaz has kindly provided instructions in post #5.Q9. Can I report a bug with respect to the ROM?A9. Yes, but you need to supply the following information. If you don't, I won't look at it.
Provide an adb logcat of the problem, and if possible describe how to reproduce it. Note that I can't help if it involves downloading any app I don't already use that requires payment or creating a userid/password.
To get a logcat, open a terminal window on your PC, connect your device to it via USB, and do this:
Bash:
# clear the logcat first
adb logcat -c
# start logcat trace
adb logcat > problem.txt
# reproduce problem
# wait until problem has occurred,
# then stop trace by hitting ctrl-c then zip the problem.txt file
# before uploading it.
Q10. How long will you build 19.1 for this device?A10. For now, 19.1 will be built for all of 2022. After that, we will make a decision depending on a number of factors.Q11. Do I need to erase everything and format my data before installing this ROM for the first time?A11. If you're coming from stock Samsung Android, or an earlier version of LineageOS, or a different custom ROM, you MUST 'clean flash': boot to TWRP recovery, wipe system, data, dalvik/art cache, and cache partitions, then Format Data, then install this ROM.
If you don't do this you're likely to run into problems, such as getting stuck at the boot animation for more than 5 minutes.Q12. What Gapps should I use?A12. Your choice! There are several well-known Gapps packages, such as NikGapps, BiTGapps, OpenGapps, and MindTheGapps. Do your own research as to what is the most reliable gapps option for you. As a courtesy to gapps users, I opened a thread at
https://forum.xda-developers.com/t/...on-for-19-1-roms-sm-t710-and-sm-t810.4480041/
for you to discuss gapps. Do not discuss gapps in this thread. Thank you.
You could also consider Google alternatives, such as Aurora Store, which mirrors the Google Play Store apps but doesn't need any Google services itself. Many Play Store apps do not actually depend on Google services.
If you are going to install any Gapps package, follow the installation instructions given for that particular package.Q13. I'm having problems with Gapps. Can you tell me why it's not working?A13. I can't answer any questions about Gapps, because I don't use them. Ask your questions on the XDA thread for the Gapps package you're using.Q14. Why isn't my post answered?A14. There are several possible reasons: the question is answered in the FAQ (in which case it will be ignored completely); or it involves apps or operating systems that I don't use; or it's about Gapps, which I don't use; or I simply have not had time to answer any questions.Q15. What speed up/optimization tips do you suggest?A15. These steps can make a big difference to performance:
Turn off animations. Go to Settings > System > Developer options, scroll down to the Drawing section, and set Window, Transition and Animator scale all to "Animation off".
Don't install Gapps unless you depend on something that only Google is providing. Use Aurora Store to get your preferred Play Store apps - they will all be available on Aurora Store. You can choose to access this anonymously or use a Google account.
Don't run more than two apps at the same time. You can probably listen to music in the background and use a web browser at the same time.
Use a web browser with built-in adblock and privacy features, such as Brave.
Use NewPipe to watch your streaming content. It has built in adblock so you don't have to watch forced ads.
Look for apps that are open source, ad-free and lightweight.
Q16. Does this ROM support Magisk so I can root my device?A16. Magisk works with this ROM as reported by beta testsers, but that could change with any revision and changes by Google. However I don't use it myself and can't help with any related issues. Direct any questions about Magisk to the XDA Magisk forum.Q17. Will this ROM ever become official?A17. With 19.1, legacy devices like ours will NEVER be official due to lack of ebpf support. See https://lineageos.org/Changelog-26/Q18. What is the difference between this ROM and others?A18. This ROM tries to be pure LineageOS with little or no modification. Other ROMs may come with a different UI, different bundled apps, etc.Q19. Will there be any major 19.1 code modifications in the future?A19. There may be some major modifications along with some slight tweaking to the SEpolicy, small bug fixes and minor code cleanup, but all the hard work - getting the rom up and running, and fixing all the major bugs - has been done.Q20. Why did you fork the trees?A20. I wanted my own private branch where I could make changes that would only affect my own personal builds.Q21. Can you build a variant of this device? For example, a LTE or S-pen version?A21. I cannot and will not try to build for a variant device if I don't physically have that device. I have to be able to boot and test it myself, and there's no guarantee that I can get those variant features working.Q22. Can I load this ROM on a variant device like LTE or S-pen version?A22. This ROM is for the device explicitly listed and will only work on that device. Do not try to install it on any other device.
ONLY if you are an advanced user and understand TWRP, adb, odin, heimdall, etc, you could try loading it on a LTE or S-pen variant by modifying the updater-script, but be warned: there are likely to be problems, including a bricked device, bootloops, or the ROM not being able to support the functionality of LTE/S-pen.Q23. Does this ROM have any wifi connection issues?A23. This ROM's wifi has been stable on the specified device ever since lpedia and I determined the root cause of the wifi problems back in July 2021 and re-installed the original S2 network 'blobs' with LOS 17.1.Q24. Is this ROM secure so I can do financial transactions?A24. Although Android monthly security patches do improve general security, this ROM's outdated kernel and old proprietary vendor blobs/drivers will NEVER get updates of any kind, and could have significant security holes.
In addition, although the ROM is SElinux enforcing, there's a good chance that the rules written (about 800+ lines of code) have some errors.
If the device is rooted, this would further weaken the security.
With this information, it's up to you to make an informed decision about whether you trust this ROM to be secure enough for your financial transactions.Q25. How do I turn off the taskbar at the bottom of the screen?A25. Goto settings, system, buttons and disable taskbar.Q26. Okay, I understand the consequences and willing to take the risks outlined, now where can I find the ALPHA rom?A26. Downloads are at https://sourceforge.net/projects/lpedia-sf/files/gts28wifi-19.1/
NOTE: lpedia has personally tested each build on his device to boot and function as described in post #1. Having said that, there's still a chance it won't work on your device due to human error, your configuration, your apps, etc. If it won't boot, always start with a complete wipe of everything and format your data in TWRP. This is known has a clean install. Backup your data before a clean install.

Tab S2 T710 Upgrade Procedure for the LineageOS 19.1 ROM by retiredtab
These installation instructions work for both Tab S2 T710 and T810, starting from a device running stock Android 7.0. I have both devices and have tested the procedure on both. I am a Windows guy, so these instructions assume a Windows PC. I am a lifelong techie guy and an Android enthusiast. My current “production” devices are Samsung S22 Ultra and Samsung Tab S7, but I do love the size and performance of the Tab S2 T710 so am extremely happy that @retiredtab and @lpedia have been successful at making Lineage 19.1 run on the Tab S2. But I am not developer, so these instructions will work for any competent newbie who’s looking for LOS 19.1 on their Tab S2 tablet. I do realize there may be alternative approaches for those who have deeper Android tech knowledge than me, but this procedure does work every time.
Step 1 – Preparation
Update your Tab S2 to the latest stock software.
Install a micro-SD card into your Tab S2.
Enable Developer Options – tap Build Number seven times.
In Developer Options, turn on USB debugging.
Connect your Tab S2 to your PC via USB and download onto the micro-SD card three files:
Retiredtab’s latest Lineage 19.1 ROM from lpedia-sf - Browse /gts28wifi-19.1 at SourceForge.net (T710) or retiredtab - Browse /SM-T810/19.1 at SourceForge.net (T810)
NikGapps-core-arm64-12.1-20220709-signed.zip from https://sourceforge.net/projects/nikgapps/files/Releases/NikGapps-SL/
Magisk-v25.2.apk from https://github.com/topjohnwu/Magisk/releases
Magisk is optional if you want/like root.
Download to your PC TWRP_3.5.2_9_SM-T710_20210719_Unofficial.tar from retiredtab - Browse /SM-T710/TWRP at SourceForge.net (T710) or twrp-3.5.2_9-0-gts210wifi.img.tar from Download TWRP for gts210wifi (T810)
Download to your PC Odin, from https://technastic.com/wp-content/uploads/2020/02/Odin3_v3.14.4.zip, and extract the zip.
Step 2 – Install TWRP Recovery
Power off your Tab S2.
Launch Odin on your PC and press OK.
Power up your Tab S2 into Download mode by holding down Home+VolDown+Power.
Then at the Warning screen hit VolUp.
Connect your Tab S2 via USB to your PC, and you should see Added!! in Odin.
Click AP in Odin and select the downloaded TWRP.
In Odin Options, uncheck Auto Reboot.
Click Log tab again.
Click Start in Odin.
Installing TWRP only takes a couple of seconds.
You will see progress in the Log, and Pass at the top of Odin when done.
Step 3 – First boot into TWRP
This part is tricky!
Power down your Tab S2 by holding down VolDown+VolUp+Power.
IMMEDIATELY the screen goes blank, hold down Home+VolUp+Power.
Keep holding down until you see the TWRP home page.
If you end up booting into Android rather than TWRP then you will have to repeat Step 2 and Step 3 again.
Step 4 – Backup your stock ROM
In TWRP, select Backup, Select Storage to choose your micro-SD card, check all the partition boxes, and then swipe Backup.
Confirm your backup is good
In TWRP, select Wipe, then Advanced Wipe.
Select all partitions except Micro SD Card (and USB OTG).
Swipe to Wipe.
Back, Back again, then Format Data
Type yes, and tap check.
Back, Back, Back, and select Restore.
Select Micro SD card and your backup.
Restore all partitions and allow restore to complete.
Reboot to System, and confirm you are back to stock.
Step 5 – Install ROM and NikGApps
In TWRP, select Wipe, then Advanced Wipe.
Select all partitions except Micro SD Card (and USB OTG).
Swipe to Wipe.
Back, Back again, then Format Data
Type yes, and tap check.
Back, Back, Back, and select Install.
Select your micro-SD storage.
Select the Lineage-19.1 ROM.
Add more Zips, and select nikgapps.
Swipe to confirm Flash.
Install takes about 3 minutes.
Wipe Cache/Dalvik, and Swipe to Wipe.
Reboot System.
Step 6 – Build your Android 12 Tab S2
First boot into Lineage is less than a minute, and then the Lineage boot animation takes less than 1 minute before “Welcome to LineageOS” appears.
At the end of the initialization process, be sure not to choose the Replace Lineage Recovery option, otherwise TWRP goes away.
Set up your Android device per your preference. I am a mainstream Google/Google Play Apps user, and I have loads of Apps, so it takes me a long time to install my Apps and set the tablet up for daily use. If you are less of a pack-rat, it shouldn’t take long!
I have found that, by not installing Magisk initially, I can restore all my Apps, including the sensitive ones such as Peacock, Netflix, Disney+, etc. All Apps run normally, and when I check Google Play/Settings and scroll to the bottom, I see “Device is certified”.
I recommend leaving tablet completely alone during the initial Apps and Data restore process. When I get impatient and fiddle around as it’s copying I’ve seen crashes.
Once all copying is done, do your unique Android setup. My go-to Android settings are:
Nova Prime Launcher (actually, gets selected during the initialization process, but I load my layout from backup at this time)
Microsoft Swiftkey
Screen timeout 30 minutes, and screen saver Clock
Dark theme off
Disable taskbar.
Plain dark blue wallpaper
Touch, screen locking, and charging sounds off
Battery %age next to icon
Default USB = File Transfer
Developer Options enabled, and USB and Rooted debugging selected
Window/Transition/Animator Scale all set to Animation Off
FX File Explorer
Microsoft Edge as default browser (with AdBlock enabled and Google as search and sync to my PC)
Raindrop, for all my cross-platform/device bookmarks
Advanced restart menu (to allow reboot into TWRP).
Step 7 – Make Root – Optional
Restart Tab S2 into TWRP.
In TWRP, install Magisk-v25.2.apk.
Reboot System
In Android install Magisk-v25.2.apk.
Open Magisk and select zygisk in settings.
Restart again.
You now have root. I test by enabling root in FX File Explorer and granting root.
Step 8 – All done! Enjoy!
I do a final and full TWRP backup once the device is solid on Lineage 19.1.
On lineage-19.1-20220811-UNOFFICIAL-gts28wifi.zip I don't have an onscreen keyboard. I rebooted into TWRP and tried the GBoard Add On, but after that stil no onscreen keyboard. Installed it with NikGapps core and retried with full. If you use full, something from Google keeps crashing.
In system settings with full NikGapps, only keyboard available is Google speak option.
Both were Clean Installs.

We found another way to workaround the missing on screen keyboard. @lpedia tested with the Google login accounts and I tested it with Bluetooth numeric PIN. It's documented back in post 1 to say
=== begin ===
keyboard bug workaround. When prompted to enter something like a Bluetooth pin or text based password, sometimes the keyboard is not shown on the screen or off screen. The workaround is to goto settings, system, languages & input, on-screen keyboard, Android Keyboard (AOSP), appearance & layout, theme and choose "Material - follow system settings".

I can try again. However, I went to languages and input and there was no keyboard option whatsoever. I tried manage keyboards, but could not activate one as well. To me it looked like there was no onscreen keyboard installed at all. So I couldn't use this workarround.
Update:
So I reinstalled, but one thing I didn't do is change initial language to Dutch. So now I am going see if I can restore my device, but so far it hasn't found my backup. Or asked to restore it. Don't know how I can reinitilaze that if not asked at setup.
Update 2: Reinstalled with NikGapps Omni this should have google setup and google restore. But didn't get question to add google account during setup. After adding account didn't get a question to restore data.

Thanks for the charging fix. Now my tablet does not get hot while charging. That's great!
But the charge does not show more than 76%. I have left it for 2 days untouched but it does not go above 76%. It did this even before the 9/11/22 version. Unless I need to recalibrate battery??? Never had to do that before.

I suggest the following:
1. boot into TWRP and see what the battery % is. If it's not 100%, let it charge to 100%.
2. After charged to 100%, boot into OS and see if it's at 100%.
3. If OS shows 100%, it's fixed. If not, repeat steps 1 and 2 at least 3 more times.

Still does not charge to 100% outside Twrp.
OK. So in Twrp it goes to 100% and on reboot it says 100% . But then again when it discharge, it will not charge above 76%. I repeated the process, but outside Twrp it does not charge above 76%.
Any ideas??

I'll answer the above in the T810 thread since that's what you have, but @lpedia and I have been using the 19.1 T710 since mid April and we would have noticed if it stops charging at 76%. I'll let lpedia comment since he uses the 19.1 T710 as a daily driver more than I do.
New build called lineage-19.1-20221010-UNOFFICIAL-gts28wifi.zip
NOTE: lpedia has personally tested each build on his device to boot and function as described in post #1. Having said that, there's still a chance it won't work on your device due to human error, your configuration, your apps, etc. If it won't boot, always start with a complete wipe of everything and format your data in TWRP. This is known has a clean install. Backup your data before a clean install.

Just for reference, the charging weirdness was not a device or ROM issue. It was on a T810 (the report of the issue was posted to this thread by accident), and was discussed on the T810 LOS 19.1 thread. It turned out that the device had an app that was interfering with battery charging. Removing that app fixed the problem.
Its working so smooth I like it! The only problem I found is the audio when I play videos in VLC player, didn't play the audio. Can't hear anything. ah! And sometimes my tablet reboots

@Kyrat - does VLC audio work otherwise, eg to play music? If not, you probably have the same problem as I came across with some versions of VLC. There's no audio output at all with VLC's default audio output method, AudioTrack. Changing that to OpenSL ES fixed the problem for me.
That setting is in VLC Settings > Extra settings > Audio > Advanced > Audio output.
