Hi,
this thread aims at keeping the LineageOS 13.0 version alive for the Moto G 2015 (osprey) device with current security patches from LineageOS (branch 'cm-13.0'). The build here has already a history in this thread on XDA - it may be worth to scroll through it to find additional information.
The build has got the following features:
LineageOS 13 with current security patches
Patched for microG (see https://microg.org, signature spoofing as switchable permission)
Squid kernel for the Osprey device (own fork)
LineageOS Jelly Browser
Current Android System Webview
CMUpdater is not part of this build
Renewed CA-certificates from AOSP master branch
VoLTE (may not work in all cases!)
Current build data
Download here
AOSP tag android-6.0.1_r81

Installation instructions
YOU ARE RESPONSIBLE SOLELY YOURSELF FOR ANY ACTIONS YOU DO WITH YOUR DEVICE !!!
Please note - I won't explain any single aspect (e.g. how to install 'fastboot' on your PC or troubleshoot USB connectivity issues under Windows). Search the net and consult the search engine of your choice or look here in XDA, there is plenty information available.
Pre-Requisites
Get familiar with the hardware keys of the Motorola Moto G 2015 (osprey) device, especially how to enter fastboot mode (switch phone off hold power + volume down together for about 3 seconds) and recovery mode (in fastboot mode, switch with volume key to the reboot recovery option and select with power key)
Have fastboot and adb installed on your PC and make sure, you can connect via USB to your device in fastboot mode and via adb
Download the most current .ZIP file of this ROM and place it to your phone's internal memory or SD card
If you wish to install Google apps (GApps), please refer to the GApps section further below
An unlocked bootloader (read the warnings carefully and backup your data!
Install TWRP recovery
If you come from stock ROM and have just unlocked your boot loader, this is the next thing to do. If you have already a working custom recovery on your device, there is no necessity to replace it.
However - I recommend to use the TWRP recovery linked here. The following instructions are based on TWRP.
To install TWRP, download the TWRP.img file (Note: replace "TWRP.img" in the following instructions with the real file name) from this section to your PC, get it into 'fastboot mode', connect the device via USB to your PC and enter the following command on your PC:
Code:
fastboot flash recovery TWRP.img
Afterwards, directly boot into 'recovery mode' (see above) - I recommend not to boot the phone's Android system after having flashed TWRP. Once TWRP has been launched, you may decide to reboot your phone and install the ROM at any time later. But the first boot after flashing TWRP should be TWRP in recovery mode.
Advanced Wipe
ONLY perform the steps described here, if you come from Stock ROM or a different Custom ROM!
Boot into recovery mode. In TWRP, choose "Wipe", "Advanced" and spefify "Dalvik", "System", "Cache" and "Data" to be wiped.
Make sure NOT to wipe "Internal memory" or "SD Card". Swipe to confirm the deletion and get back into the main menu.
GApps
The following instructions only apply for the 1st variant, do not flash Gapps over the "microG build":
You do not need to install GApps, but you may wish to do so. In that case, download GApps from here and put the .ZIP also to the SD card or Internal memory of your device.
Choose ARM as platform, Android 6.0 and the flavor of your choice. I recommend "pico", as this leaves you the most freedom to only install, what you really need; you can later still install all the Google products you want and do not need to live with pre-installed Google applications you have no use for. The 'microG patch' in this ROM has no negative impact on installing Gapps.
Install the ROM
In the TWRP main menu, choose "Install". A file manager appears to let you navigate to your internal memory (path /sdcard) or your SD card (path /external_sd).
Choose the .ZIP file of this ROM and swipe to flash. If you update from a previous version of this ROM, you don't need to perform a wipe.
If you had GApps already installed before the update, there is no need to flash them again. They will be automatically restored during the flash process.
(Note: If you wish to get rid of GApps, navigate to TWRP's file manager in the Advanced section of the main menu, go to path /system/addon.d and delete the file 70-gapps.sh, before flashing the ROM update)
If you come from a different ROM (or stock firmware), make sure that you have performed the Wipe steps above.
If you wish to install GApps, select the respective .ZIP file directly afterwards, do not boot into Android before having flashed GApps. When finished flashing, return to the main menu, choose "Reboot" and then "System", which will cause your phone to boot into Lineage OS 13.0 - be patient, the first boot after flashing a new ROM takes quite long!
microG Installation
These instructions apply to the 1st 'default' variant, not the 'microG build' (which has already microG installed)
The ROM is patched for the use of microG, but it does not contain the microG system components.
The best way to obtain them is to include the microG repository into the F-Droid store as described on the microG Download page, where you will also find links for the direct download of the .apk files.
Please refer to the official installation instructions. However, there are three pieces of information, which are explained on the microG pages, but unfortunately not directly in the installation instructions, so I would like to point them out here:
Download the 'unstable' Gms Core version 0.2.4-105-... to avoid "outdated play services" warnings
The Location Provider functionality is included in Gms Core, but also available as separate application. I recommend Gms Core - however, the explanation is not included in Gms Core, but only here
To grant the signature spoofing permission, go to Settings - Apps - Advanced (the 'gear' icon) - App Permissions - Spoof package signature; it is not possible when you enter the individual app's permissions menu

Security Hardening (microG build)
Details about additional security hardening in the "microG build"
1. SQLite 'Secure Delete' feature
This sanitizes deleted data by overwriting it with zeroes, rather than having it persist within SQLite's free list.
Backport from Oreo, see https://android-review.googlesource.com/q/topic:"secure_delete"
2. Restrict SET_TIME_ZONE permission to system apps
Backport from Oreo, see here
3. Enhanced Privacy Guard (1) - Sensor permission switches
An own sensor template to control access to motion sensors (ask mode) and all other sensors (allowed by default, but can be restricted) has been implemented into the Privacy Guard. Commits: (1), (2), (3)
4. Enhanced Privacy Guard (2) - Switches for 'Read phone state' and 'Storage'
The existing AppOps to read the phone's IMEI and to control access to the SD card have been made accessible.
This is a cherry-pick of the proposed LineageOS change here
5. Restrict access to /proc/net for user apps
An adapted SELinux policy prevents user apps from accessing the /proc/net pseudo file system, which can be misused to monitor and track the phone's internet traffic. For technical backgrounds, see here. This is the main commit. For the legitimate use case of the smart phone owner him/herself monitoring the network traffic to see, what the installed apps do, the app Privacy-Friendly Network Monitorhas been bundled
6. Access to timing information in /proc restricted
To prevent side-channel attacks as described here, the respective Oreo patch has been back-ported.
7. Cloudflare (instead of Google) default DNS
Cloudflare DNS has a better privacy policy than Google Public DNS and has DNS-over-TLS and DNS-over-HTTPS. In the deafult DNS settings (as fallback) and network diagnostics, the Cloudflare DNS adresses 1.1.1.1 and 1.0.0.1 are specified as defaults (instead of Google's 8.8.8.8 and 8.8.4.4)
8. Privacy-preferred default settings
When newly installed, the below settings are defaulted, different from standard LineageOS 14.1 (all setting can be changed at any time later):
Privacy Guard is enabled on install (proposal during Setup)
Anonymous LineageOS statistics disabled (proposal during Setup)
The standard browsing app does not get the location runtime permission automatically assigned
Sweet..
Nice. Good to see this as separate post.
Every time the ambient display lights up the screen, it is in on a high brightness mode. And the moment I tap, it gets back to normal brightness. I know this could be a cm13 issue but, any way to resolve this ?

Sure thing.
Also, is this volte supported or should I flash the volte patch ? Because I can't seem to get it work. I am on the latest build.
VoLTE
As you can see in the old thread, there have been some discussions about VoLTE support (and also some attempts from my side to get it running).
Let me quickly summarize:
I have tried the VoLTE patch(es) from XDA - VoLTE menu was there but no VoLTE calls on my phone
I have tried to create a test build with the contents of those patches and also looked at what was done in cm-14.1 - same result: menu there, but no VoLTE calls (LTE symbol disappears when calling)
Got mixed feedbacks from people using the test build - works well for the ones and does not work or stops working after reboot for others . . .
LineageOS 14.1 is supposed to have VoLTE support f. osprey - same story, not on my phone (menu entry there, but *#*#4636#*#* menu and IMS status there tells VoLTE not available - tested with SIM cards from different carriers)
So I'm having trouble to get it working on my device (XT1541 16GB) at all. On my repo's at github, the msm8916 device and vendor tree have two volte branches for testing.
Any insight, advice and/or build suggestions welcome

Hi, haven't really noticed anything unusual in the log, I also use afwall and Xprivacy. Only noticed you use a battery app, but log does not indicate any issues... So I am afraid I can't really help, as I can't reproduce this behavior on my device.

Yeah, I use the betterbatterystats from xda. I guess I will try and do a dalvik cache clear and if possible do a clean rom flash in the near future and try again. Else, it must be some device specific issue.
Anyway thanks a lot for your time. I appreciate it.
My daily ROM, please update.

LineageOS 18.1 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
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_gts28wifi
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 my unofficial TWRP 3.5.2_9. Get it from
https://sourceforge.net/projects/retiredtab/files/SM-T710/TWRP/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. lpedia 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's working" 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 post #37.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 #11. 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

https://github.com/retiredtab/andro...mmit/9d019f0a3be789850a9add18d042990631f05b44
Previously, if the device was off and you plugged in a charger, it would show a battery icon and this would display indefinitely giving no sign of charging animation. With this workaround, the battery icon is displayed for a few seconds and then a white circle with a charge symbol inside it is shown to indicate it's charging.
After a few seconds, the screen will go blank and continue charging. The side effect of this workaround is that in order to turn on the device, you first must unplug the charger and then turn on your device. If you try to turn on the device with the charger cable plugged in, it won't turn on.

Hi there, thanks for your ROM. I would like to report a bug with using it.
May 12, 2022 release "lineage-18.1-20220512-UNOFFICIAL-gts28wifi" with "open_gapps-arm-11.0-pico-20220503".
All factory resetted through TWRP, after flashing and booting the device it is stuck on "Just a sec..." when selecting set up offlie. If you try to set it up over wifi it is stuck on "Getting your tablet ready."
I've included my logcat, if you need more info or another reproduction please let me know.
Thanks!

Hi, @kimrosebush. Thank you for sending a logcat.
This kind of problem is often because the gapps package isn't quite right for some reason. Google Setup needs the underlying Google Play services to be present and working properly. This line from your logcat suggests they are not:
Code:
05-12 22:29:54.077 4147 4225 W GooglePlayServicesUtil: com.google.android.setupwizard requires Google Play services, but they are missing.
A few questions about the process you followed:
1. What OS was on the T710 before you began? If it was stock Android, was it the latest version available?
2. Did you install the correct version of TWRP (see Q5 in the FAQ)?
3. When you say "All factory resetted through TWRP", what did you actually do?
4. When did you install the gapps package? Just after the ROM, before first boot?
Have you checked whether everything else is working? In particular, is wifi connecting and working properly? [Pressing the Home button should get you out of the stuck Google Setup.]

Hey @lpedia thanks for the reply.
1. LineageOS 17.1 I believe was the build.
2. Yes I installed the provided version.
3. I formatted all partitions except SD, flashed the images and then formatted the SD to ensure a completely wiped device.
4. Just after the ROM.
I tried a few times further, then I decided to go for the 'full' OpenGApps package; once I used this one and attempted the offline setup again I was able to proceed further in configuring the tablet.
Thanks for the hint in the right direction. Am glad to be on Android 11 now.
Kind Regards,
Kim
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.
https://forum.xda-developers.com/t/...rsions-devices.3098071/page-367#post-86885091
It's also shown up in other roms like
https://forum.xda-developers.com/t/...7-1-04-30-2022.3937956/page-100#post-86885353
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.

Good to hear!
Note that you don't have to be quite so brutal about wiping absolutely everything for a 'clean' flash. I manually wipe Dalvik / ART Cache, Cache, and System, and then Format Data. I have never reformatted the SD.
If you have any further trouble, I suggest you try starting again with a clean flash and a different gapps package, or try doing without any gapps, as @retiredtab has recommended in the post above.
In my experience, some gapps packages, or sometimes just a particular version of a gapps package, don't work with some ROMs. I have not tried opengapps, but I can confirm that BiTGApps-arm-11.0.0-R45_signed.zip does work on my T710 with this particular ROM version.
I personally like BiTGapps because it installs only the bare minimum needed (Google services and Play Store; doesn't even automatically run Google Setup) and doesn't have to be installed before first boot. So it's possible to install LOS, boot the system, make sure everything's working, then go back into TWRP and install gapps. If any problems turn up, this approach also makes it easier to tell whether it's something to do with LOS or with gapps.
You could also try running LOS without any gapps, and if you decide you want gapps after all, install BiTGapps without having to clean-flash and start again.
I just installed this rom two days ago. It has been working great. Today, however, I noticed that Trust gave me a message about the build having public keys. Yesterday, I don't recall getting that message. Also, root checker says "root access is not properly installed." The last time I checked, it was not rooted. Finally, my CRAVE (a Canadian streaming service) app won't play videos but gives a "device is rooted" message. Netflix works however.
Would you have any idea what is going on or how I should deal with this?
Thanks,
MC

On April 6, @lpedia and I had a PM discussion about signing builds.
lpedia wrote
Code:
"About signing builds ... an issue with just using the default test-keys signature is that someone can easily create
their own builds and pass them off as someone else's, possibly adding malicious or just plain bad code, and their
package would look just like the original."
I replied
Code:
"For our purposes, maybe we should just include the sha256sum and recommend that the users verify
them to ensure the file downloaded correctly and it wasn't modified?"
To get stop seeing that trust message, goto settings, privacy, trust, turn off build signature.

I can't see the Crave app in Aurora Store. I use the app devcheck to check for root access and the screenshot clearly shows it's not rooted.
There's nothing in my code to enable root. In fact, I don't even want root on my devices.
For Crave, you can try using Magisk and it's hide root function to see if that will fool Crave into thinking the device is not rooted.

I did installed the above root checker app and got the same message. That is, the T710 rom, by default is NOT rooted. I don't know why Crave would say it's rooted.
I believe root checker's main function is to verify that your rom is "rooted" so when it says "root access is not properly installed.", it's trying to tell you that your attempt to use Magisk or similar type app to root the rom was unsuccessful.
BTW, you are better off using devcheck as it's an excellent ad-free utility that I use on a regular basis to help develop this rom vs the ad-infested root checker app. While devcheck isn't open source, it's written by flar2 who is a xda member here.

Root Checker Basic says "Sorry! Root access is not properly installed on this device" when asked to confirm root status on an unrooted device. So as far as that app's concerned, it just means "I can't confirm it's rooted". Which is to be expected if it isn't rooted and you haven't even tried to root it.
If that isn't the app you're using, see if you can find out what it means to your particular root-checker app.

Did the CRAVE app work on this device when it had the stock Samsung ROM? Do you have to register devices to receive this service? If so, might it need to be re-registered? Because its device ID will have changed.
Thanks for suggesting devcheck. It says I'm unrooted. Perhaps Crave noticed the unlocked bootloader or the custom ROM.
It did work with stock. It was registered, twice in fact. I deleted both, registered it again. The ap still says I'm rooted. Oh well, that's ok, I can use crave through a browser.
BTW do you know where I can find the stock keyboard?
Thanks

If you mean the Samsung keyboard - sorry, no, I don't. I switched to a different keyboard years ago. Google's GBoard has similar functionality, I think. MS SwiftKey is OK, too - has the best (most relevant) suggested text of any of the keyboards I've tried.
ROM working fine for me after trial and error with various gapps. FWIW I ran into the "just a sec " with opengapps. I finally had some joy by flashing the rom, but not gapps. Boot the ROM and completely setup it up Lineage. Then I restarted and flashed open gapps. When I rebooted everything came uo fine and has been solid eversince. Kudos your you gentlemen for fixing the Wifi ! Its been nice to have it work stably.
LineageOS 18.1 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
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
https://sourceforge.net/projects/retiredtab/files/SM-T810/18.1/

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.

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.
https://forum.xda-developers.com/t/...rsions-devices.3098071/page-367#post-86885091
It's also shown up in other roms like
https://forum.xda-developers.com/t/...7-1-04-30-2022.3937956/page-100#post-86885353
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?
I'm NOT a gapps user so I will NOT be participating in this thread. I'm not supporting or answering any gapps project questions.
This thread is for users who want/need to run gapps with 19.1 on exynos5433 devices like SM-T710 and SM-T810
I opened this thread as a courtesy for users who want/need gapps.
At last count there were 5 gapps projects and they are in various states of "working" wrt to 19.1. It's your responsibility to put in some hours of research to find out what gapps works for you.
All I can say is that some testers report that NikGapps 12.1L arm64 core (May 1, 2022) work. Despite the arm64 name, that version WILL work on exynos5433. Your mileage may vary.
https://sourceforge.net/projects/nikgapps/files/Releases/NikGapps-SL/01-May-2022/
Reserved.
I can confirm that I have successfully installed NikGapps Core along with @retiredtab's T170 and T810 LOS19.1 ROMs. I have my complete set of Google Play Apps available to me on the tablet after installing them, including 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've tried to install BitGapps pico + Flamegapps basic (both ARM and ARM64 versions).
NikGapps64 finally worked.

Installed the ROM on clean wipe on Galaxy Tab S2 T810. Then NikGapps Full thru Basic in different tries.
1. With NikGapps Full to Basic there is no onscreen keyboard that comes up to set up wifi or PIN. Only a Google Voice typing error shows up. How is this solved?
2. After set up without Wifi, the tablet says "Tablet starting....." and does not go further.
Any ideas welcome....

Did you "format data"?
That solved it on mine (with the 2nd flash) testing the prealpha build.
I took only core instead of basic.
I had this in my 19.1 msm8916 post #1, but forgot to add it to exynos5433 post #1. The following is now added to 19.1 T710 and T810 post #1. This would also apply to things like wifi password, etc, not just bluetooth pin.
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.

I figured this out and everything runs good.
I used two files (one file in attachment). The zip file is flashed from TWRP. I also installed the Gboard apk from :
Gboard - the Google Keyboard 12.1.06.463429027-beta (arm-v7a) (nodpi) (Android 6.0+) APK Download by Google LLC - APKMirror
Gboard - the Google Keyboard 12.1.06.463429027-beta (arm-v7a) (nodpi) (Android 6.0+) APK Download by Google LLC - APKMirror Free and safe Android APK downloads
www.apkmirror.com
and apk was installed normally. Gboard gets installed and all is good. I think the apk alone should do it, but I did not try that alone. (For some reason attaching the apk file to this post fails). Once this is done and the Wifi is set up one can then download any other keyboard they want from app store.
Also, I don't recommend using NikGapps above "basic", on Tab S2 T810. A Gapp keeps crashing and the tablet is stuck on "Tablet starting.....".
I downloaded Basic NikGapps from here: https://sourceforge.net/projects/nikgapps/files/Releases/NikGapps-SL/09-Jul-2022/

Please see my post above.
I struggled with Installing Gapps on the latest Nov 11, 2022 release.
Tried:
NikGapps NikGapps-core-arm64-12.1-20220908-signed.zip and NikGapps-basic-arm64-12.1-20220908-signed.zip - both installs without issues in TWRP but no Play store or any other apps in the system.
BiTGApps-arm64-12.1.0-v1.7_signed.zip - fails with error "unsupported platform"
BiTGApps-arm-12.1.0-v1.7_signed.zip - installed and Play Store is visible. Get it here https://bitgapps.github.io/download.html

I installed NikGapps-omni-arm64-12.1-20220709-signed.zip from twrp and it is working well. I have the play store.
I was surprised to see that it is an arm64 version even though ( I thought that) the t710 (exynos) has an arm32 processor.
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.

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.
