Install PixelExperience on barbetWARNING: I copy and pasted thes instuctions. Please go to the offical guide for your device Barbet https://wiki.pixelexperience.org/devices/barbet/install/
WARNING: These instructions only work if you follow every section and step precisely.
Do not continue after something fails!
Basic requirements
Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
Make sure your computer has adb and fastboot. Setup instructions can be found here.
Enable USB debugging on your device.
warning
WARNING: Before following these instructions please ensure that the device is on the latest Android 13 firmware.
This is not necessarily the newest available version! Please up- or downgrade to the required version before proceeding (guides can be found on the internet!).
Flashing the vendor boot partitionwarning
WARNING: This platform requires the vendor boot partition to be flashed for recovery to work properly, the process to do so is described below.
Download this vendor_boot.img file.
Power off the device, and boot it into bootloader mode:
With the device powered off, hold Volume Down + Power.
Flash a the downloaded images to your device by typing (replace <vendor_boot> with the actual filename!):
fastboot flash vendor_boot <vendor_boot>.img
Unlocking the bootloaderinfo_outline
NOTE: The steps below only need to be run once per device.
warning
WARNING: Unlocking the bootloader will erase all data on your device! Before proceeding, ensure the data you would like to retain is backed up to your PC and/or your Google account, or equivalent. Please note that OEM backup solutions like Samsung and Motorola backup may not be accessible from PixelExperience once installed.
Enable OEM unlock in the Developer options under device Settings, if present.
Connect the device to your PC via USB.
On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
adb reboot bootloader
You can also boot into fastboot mode via a key combination:
With the device powered off, hold Volume Down + Power.
Once the device is in fastboot mode, verify your PC finds it by typing:
fastboot devices
If you don’t get any output or an error:
on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable and port!
Now type the following command to unlock the bootloader:
fastboot flashing unlock
info_outline
NOTE: At this point the device may display on-screen prompts which will require interaction to continue the process of unlocking the bootloader. Please take whatever actions the device asks you to to proceed.
If the device doesn’t automatically reboot, reboot it. It should now be unlocked.
Since the device resets completely, you will need to re-enable USB debugging to continue.
Flashing the vendor boot partitionwarning
WARNING: This platform requires the vendor boot partition to be flashed for recovery to work properly, the process to do so is described below.
Download this vendor_boot.img file.
Power off the device, and boot it into bootloader mode:
With the device powered off, hold Volume Down + Power.
Flash a the downloaded images to your device by typing (replace <vendor_boot> with the actual filename!):
fastboot flash vendor_boot <vendor_boot>.img
Temporarily booting a custom recovery using fastboot
Download the PixelExperience Recovery. Simply download the latest recovery file.
Connect your device to your PC via USB.
On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
adb reboot bootloader
You can also boot into fastboot mode via a key combination:
With the device powered off, hold Volume Down + Power.
Once the device is in fastboot mode, verify your PC finds it by typing:
fastboot devices
If you don’t get any output or an error:
on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable (preferably use a USB Type-A 2.0 one or a USB hub) and port!
check
TIP: Some devices have buggy USB support while in bootloader mode, if you see fastboot hanging with no output when using commands such as fastboot getvar ... , fastboot boot ..., fastboot flash ... you may want to try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub.
Temporarily flash a recovery on your device by typing (replace <recovery_filename> with the actual filename!):
fastboot flash boot <recovery_filename>.img
info_outline
NOTE: Outdated fastboot releases dropped legacy A/B support, so it might attempt to flash to boot__a / boot__b rather than boot_a / boot_b if you try to flash boot. In this case, you must update fastboot to a release newer than or equal to 31.0.2. Alternatively, you can manually specify which slot to flash to based on what slot fastboot failed to flash to. For example, if fastboot fails to flash to boot__a, you must flash to boot_a.
Installing PixelExperience from recovery
Download the PixelExperience installation package that you would like to install or build the package yourself.
If you are not in recovery, reboot into recovery:
With the device powered off, hold Volume Down + Power. Then use the menu to select Recovery Mode.
Now tap Factory Reset, then Format data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage, as well as format your cache partition (if you have one).
Return to the main menu.
Sideload the PixelExperience .zip package:
On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
On the host machine, sideload the package using: adb sideload filename.zip.
check
TIP: Normally, adb will report Total xfer: 1.00x, but in some cases, even if adb: failed to read command: Success/No error. In some cases it will report adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.
Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.
info_outline
NOTE: The first boot usually takes no longer than 15 minutes, depending on the device. If it takes longer, you may have missed a step, otherwise feel free to get assistance
check
TIP: If the installation process reports the message "(~47%) adb: failed to read the command: No error", do not worry, the process was completed successfully and you can restart the device.

Just creating a thread to spread the word my friends

Thanks for this, exactly what I've been looking for (stock ROM with volume button playback control, let's go!)
Flashed using instructions (factory reset, sideload). No issues, things seem to be working smoothly. Will observe battery life over the next few days but not expecting much difference either way.

Thanks for the nice Rom
Is there a version of PixelExperience for Pixel 5a Barbet but Android 11 (Plus edition)?

you might be able to build your own rom and switch to the branch eleven-plus, but not sure if it would actually work or not. also i am sure it would be outdated for kernel security patches and other updates. build time on my dual cpu e5-2667v2 (32 cores total), 160gb of mem, WD SN750 1tb nvme and 1gbp internet running debian bookwork with tkg kernel is about 2hrs from start to finish. i just build a twelve-plus yesterday and i was surprised that everything worked out of the box using adb sideload on the unoffical twrp. the experience recovery actually installed and worked this time. rom is very smooth or i should say smoother than it was. a few new features were added. some were moved to a different spots. magisk install was easy with the working experience recovery allowing adb sideload to flash magisk. i might actually stick with this rom for a while.

yeah.
steps
1. unlocked bootloader
2. flashed fresh factory image (12.1.0 (SP2A.220405.003, Apr 2022)) from google dev site (check marked full wipe & force flash all partitions)
3. waited for phone to fully boot up. did offline setup skipping everything until i hit home screen
4. went to settings enabled developer mode & usb debugging
5. rebooted to bootloader (adb reboot bootloder)
6. toggled bootloader until i seen recovery then booted into stock reocovery
7. power + vol up for 3 sec then release you should get the stock recovery menu. do a factory reset / wipe data
8. reboot back to bootloader in the menu options of stock recovery
9. boot unoffical trwp from nijel8 (fastboot boot twrp-3.6.0_11-0-barbet.img)
10. in twrp go to advanced and adb sideload. set twrp to adb sideload
11. download https://drive.google.com/file/d/1yJdmMDap95-vYVZEhUUrZ2m3E45Y6ARg/view?usp=sharing (sha-256 checksum) or https://drive.google.com/file/d/1yJdmMDap95-vYVZEhUUrZ2m3E45Y6ARg/view?usp=sharing (untouched rom direct from pixel experience) if you don't care about checksum you can skip it.
12. adb sideload the rom (PixelExperience_Plus_barbet-12.1-20220423-2211-UNOFFICIAL.zip) note it fails at 47% and you might see a bunch of red warning on twrp. just ignore them and reboot the phone. pixel experience is now loaded on the phone. i had to do the whole process twice because twrp messed up the first time due to it not being officially up to 12 and sideload sometimes being flaky.
13. after setup was done i enabled debugging again and booted to bootloader, then recovery mode. pixel experience recovery should now be loaded. its touch screen or volume controlled. select adb sideload and side load magisk 24.3.apk or you can rename it to zip. doesnt matter. reboot phone. check app drawer. magisk will be there. if not give it a second it will pop up. tap the app to download full version. enjoy rooted & pixel experience
the rom is compiled directly from pixel experience source. i do not mod or edit anything. i just let my computer sweat at 100% usage for 2hrs and hope like hell the rom works.
i can try an eleven-plus build if you want but i doubt it will work and would probably end up bricking your phone.
this is the process i used. i take not responsibility if you brick your phone.
usually your brick is a soft brick holding power + vol up + vol down for 30sec will force restart your phone. then power off then power + vol dow to get back to bootloader so you can work with it again (factory flash or whatever)
android base is 12.1.0_r4

How is fingerprint sensor working, does it also have lag if AOD is not enabled? March update introduced 2 seconds delay after FP sensor registers your finger before it shows you your home screen. If you use AOD that issue is not present.

I noticed that sometimes the scanner simply refuses to understand the finger, I also noticed that when AOD is on, if you put the phone with the screen down, it does not go out, but if you turn up the screen and close the proximity sensor, it goes out

[RECOVERY][TB-X505F][UNOFFICIAL] TWRP 3.6.x for Lenovo Tab M10 HD

This version of TWRP works on the Lenovo TB-X505F (wifi).
For the TB-X505X, see this thread. For the TB-X605F/L, see this thread.
For the TB-X606F/L, see this thread. The X606F/L is the second gen M10 and it uses a Mediatek SOC.
Code:
#include <std_disclaimer.h>
/*
* We are not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at us for messing up your device, we will laugh at you.
*/
Working:
AFAIK, everything is working including:
data decryption
MTP
Known issues:
time not adjusting for Daylight Saving
OTA (for a workaround see this post)
Before installing TWRP
Before you install TWRP, upgrade your tablet to the Android 9 (Pie) or Android 10 (Q) stock ROM.
This tablet shipped with Android 8 (Oreo), in which the bootloader did not allow unlocking. When you tried to unlock the bootloader, it gave this error message:
Code:
fastboot oem unlock-go
FAILED (remote: 'unknown command')
fastboot: error: Command failed
Installation
It is recommended that you also install Magisk. This will ensure TWRP remains your default recovery.
Step-by-step guide
download TWRP to your PC (see the Download section below)
download magisk.apk to your MicroSD or OTG device. Get the latest Magisk apk file here. Rename the filetype from apk to zip (for example Magisk-v22.0.zip)
if your bootloader is already unlocked, go to step 4. To unlock bootloader:
on tablet: go to Settings->System->About and press "Build number" 7 times to enable Developer Options.
on tablet: go to Settings->System->DeveloperOptions. Turn on: "OEM unlocking" and "USB debugging".
connect tablet to your computer. Tablet will ask for permission to "Allow USB debugging". Tick "always allow" and select "OK".
backup any files you want to keep to an external device (MicroSD/OTG/computer), because the next step will wipe all your photos, files, google account etc on the tablet.
Now unlock the bootloader:
Code:
adb reboot bootloader
fastboot oem unlock-go
fastboot reboot
flash the twrp image:
Code:
adb reboot bootloader
fastboot flash recovery twrp.img
if you haven't loaded Magisk yet, go to step 6. If you have already loaded Magisk, you can just reboot and you're finished:
Code:
fastboot reboot
adb reboot recovery
load Magisk (step one): reboot to recovery. Do not reboot into the system, because it will over-write TWRP with stock recovery. If that happens, go back to step 4 and start again. When you issue the reboot command (below), you have to immediately press the button combination to reboot to recovery (TWRP). Here are the steps:
issue the reboot command:
Code:
fastboot reboot
immediately press and hold all three buttons (Pwr+VolUp+VolDown). The tablet might reboot twice. Release all the buttons when you see the TWRP screen, or hear your PC acknowledge that ADB is connected.
load Magisk (step two): flash Magisk. In TWRP:
select "Install"
use "select storage" to locate device you stored magisk.zip on.
press the OK button
select the Magisk zip file
swipe to confirm Flash
when Magisk is finished, hit the "Reboot System" button
finished!
If you prefer to use button combos, rather than fastboot/ADB commands:
Vol Down + Power = fastboot mode
Vol Up + Vol Down + Power = recovery mode

Not that I know of. The bootloader accepts the command fastboot reboot recovery, but boots to system anyway.

Hello there, I've been looking how to install this on my slow tablet for almost like an hour. Could there be some tutorial or extended explanation to the process and installation, I'm such a noob, sorry.

This worked for me. Thank you for your effort and the TWRP!

Worked for me too - many thanks!
Can't wait for a custom ROM!
TWRP Recovery Installation Steps
1. Download android platform tools
2. Unlock developer mode on the M10
3. Enable USB debugging on the M10
3. OEM unlock enable on the M10
4. XDA download TWRP copy to sd
5. Download Magisk app (from Github!!! johnwu), change extension to .zip
6. Adb to fastboot
7. fastboot flash recovery [filename.img]
8. Turn off device
9. Turn on device holding all 3 buttons, release when see Lenovo splash screen
10. In TWRP find Magisk zip
11. Install Magisk
Stock ROM Recovery
1. Download qualcomm drivers 64 bit install
2. Download Lenovo recovery and image tool windows app from Lenovo support website
3. Fastboot oem edl
4. Turn off M10
5. Start recovery windows app, wait till instructions
6. Hold volume up (up is the side of the button closest to the front camera) and insert cable
7. Release button after windows app detects device
8. Troubleshoot by checking windows device manager for the M10 appears as a Qualcomm device

I'm thinking about getting one of these tablets, but before I do so I'd like to know that the screen lock still works after installing TWRP.
This might sound like a crazy question, but my Samsung Tab A won't set a screen lock - pattern, PIN or password - once TWRP has been installed, and I'd rather not run into the same issue again.

Many thanks.

Thank you! TWRP is working fine!
Stupid me flashed before I installed the Android 10 OTA, so I had to temporarily go back to stock recovery. Unfortunately beamingbadger's method didn't work for me.
This is how it worked for me:
Download the OTA via Lenovo's "Rescue And Smart Assistant"
The stock recovery image will be in the Download folder (default path: C:\ProgramData\LMSA\Download\RomFiles) called "recovery.img"
Flash the recovery.img the same way as you would with the twrp img (adb reboot bootloader -> fastboot flash recovery recovery.img)
fastboot reboot
Install OTA
Flash TWRP recovery + Magisk again (follow the steps from the first post, skip bootloader unlock)

The method I use to install OTAs is:
open Magisk App
select "Uninstall Magisk", then the "Restore Images" option
reboot to Android (you will have no root access and stock recovery is restored)
apply OTA
re-flash twrp and install Magisk
NOTE 1: if you've unencrypted your data partition, it will be re-encrypted by this process.
NOTE 2: the new Magisk App (v22) can be installed in TWRP by renaming the *.apk to *.zip. See the new install instructions.

What's involved with running gsi ROMs on this device? It's got the same SoC as my Samsung Tab, which runs them well, so I'm assuming that this tab will also, but I'd like to know if there are any traps that I need to be aware of.

I can partly answer my own question. It all went more smoothly than I expected: installing TWRP, Magisk and then LineageOS R Mod //LiR, followed by Disable_Dm-Verity_enfec.zip.
If I want to try other GSI ROMs, do I need to flash stock before trying another one? I've had some trouble doing that (won't boot) and it's possibly to do with encryption.

On my X605F I do this in twrp for a new GSI install:
format (not wipe) data partition. This is the option where you have to confirm by swiping.
factory reset. This clears the caches.
restore the stock boot and vendor partitions (from a backup I made). This is because Magisk can touch these partitions.
install the GSI system image
install anything else I need like disable_Dm-Verity, Magisk, gapps etc
I don't know what LOS R Mod //LiR does to your system. If it touches any other partitions, you should restore those to stock too.

Thanks for that. It gives me something to go on with. I've downloaded the stock ROM from lolinet, so I can grab the boot and vendor images from that.

I was able to try a couple of other GSI ROMs and I've settled on AndyYan's LineageOS 17.1 for now. The only serious installation issue I had - which I can laugh about in hindsight - was thinking I'd got myself into a very bad bootloop, when all I needed to do was let go of the power button after the Lenovo logo appeared.
On this tablet, there is no navigation capability at all (no navbar, no gestures, no setting to configure them) on installation, and I have to set it using adb. I suspect it goes back to PHH basic ROMs, but I don't feel like doing yet another install and testing right at this moment. Is this happening on the other tablets that you're testing, or is it unique to this one?

I just posted the v3.5.1 update to twrp.
It's also changed to landscape mode, as many of you requested.

Quick question, how do i apply new system updates with twrp installed? Should i not bother? Also, i forgot how to block check for updates!

will this allow flashing of stock roms download from lenovo recovery? ive been stuck on an ancient android 9 version because the ota updater fails.

I would like to express special thanks to all the developers who contributed to the LineageOS port for Galaxy Tab S6 Lite + all the other developers who contributed to sepolicy & hardware parts for Samsung SLSI (Exynos) devices. Porting LineageOS to A21s would have been much harder without them.

Patch the boot.img with magisk app. Then reboot fastboot and flash the patched.img with fastboot.
This is, and will always be, the recommended way of installing magisk and getting root.

If we already have LOS 19.1 and recovery, do we still need to install the new recovery and factory reset?
edit: I renamed the new recovery image to recovery.img and then used 7zip to make recovery.tar and flashed it with Odin. But when I booted to recovery, all I got was a blank screen. Had to reflash the 19.1 recovery to get it back.

It appears the dev wants you to use Telegram for support and doesn't answer questions here in XDA. But I didn't get much support there either. When I asked what gapps to use, It just pointed to the Nikgapps site. But when I flashed the CORE version for T, Play Store didn't recognize the internet connection. Tried to revert to 19.1 and it wouldn't let me. Claimed it was a downgrade and not allowed. Had to flash the latest stock version via Odin, with all of the Samsung and Google bloat.

Well, I got it to work in spite of the lack of support. Had to use the OMNI version of Nikgapps instead to CORE. One little nit pick discovered so far. /Setup/System/Status Bar setting to change the battery icon to text and show percent doesn't work. But that is easy to live with.

If we already have LOS 19.1 and recovery, do we still need to install the new recovery and factory reset?
edit: I renamed the new recovery image to recovery.img and then used 7zip to make recovery.tar and flashed it with Odin. But when I booted to recovery, all I got was a blank screen. Had to reflash the 19.1 recovery to get it back.

LOS 20 recovery here. I do think we have to use same recovery version as the instructions say.
The image has been updated today and now I see the lineage OS 20.0 recovery.

if flashed it with the old recovery but the zip check false and then you have to flash anyway
i check and the file size of both recovery where the same thought that is just for the ones that need it for flash for the first time

Just downloaden every thing with a AVG Antivirus alert.
For now I'll wait and maybe test later.
edit: the alert was from a know false positive.
For me better safe than sorry.

Well I built that zip myself, I can assure you there's no malware.
BTW Antivirus apps on android are only a waste of resources.

Updated with September securitypatch and more lineage features

Is the changelog link broken? When I try it to see if I want to flash the latest version, it just times out.

You're not owed support by anyone. OP could flip off every user and **** off forever, but they'd still have done their work for the community. Thanks for the tips, though!

I didn't claim I was owed support. I merely stated that I didn't get any and that I was able to get it working in spite of that.

Device reboots after opening camera. Probably issues with camera hal

So far so good, except I cannot for the life of me get the Google keyboard to work...all other gapps are fine...

Well, the dev for this ROM has convinced me to sell my S6 and buy a newer tablet that has support here in XDA. Apparently, he will only offer support in Telegram because, in that app, he can ban anyone who disagrees with him. So, no support if you want, TWRP, Magisk, Nixgapps, custom kernels or anything else he doesn't like.

What reason would we have to ban people who want support? He doesn't provide support for TWRP because it's a discontinued project and because it worked terribly on the tablet. That's like asking Samsung for help on a flip phone you bought in 1994 that's been discontinued for quite a while. I don't think I recall him actively rejecting people's technical support for Magisk, NikGapps, or Custom Kernels when I was in his Telegram, he only said that he recommends alternatives to Magisk and NikGapps. I don't know if you're writing this after you were banned but the only time he proactively rejected support in people's devices is when TWRP was in the equation.

{Mod edit: Quoted post has been deleted}
It is being actively supported by legacy devices that can't handle encryption and on ROMs made by unknowingly devs.
Also you were told multiple times that encryption is not an optional thing, especially on T. And some users do care about their data not being just accessible when the device gets stolen.

Installation instructions
Spoiler: Installation instructions
Installation requirements
- A computer
- ADB installed on the computer, you can find a guide here
- Odin (v3.14.1 is verified to work fine), you can find it here
- A decent battery level on the device
Step 1 - Unlocking the bootloader
You may skip this section if you have already unlocked your device
- Enable developer options
- In developer options, toggle the "Allow OEM unlocking" setting
- Reboot into download mode following the instructions below
- Once into download, long press the volume up button and follow the instructions on the screen
- After the bootloader is unlocked, your data will be erased, so make sure to back it up first.
- Now, once the system has finished booting, you MUST connect to a WiFi network, enable developer options again, and make sure that the OEM unlocking toggle is on and grayed out. If you do not see the toggle on the developer settings, close the settings and try again a few times.
- Once you see the toggle greyed out, all is set.
Step 2 - Installing the LineageOS recovery
In order to flash the ROM, you need a custom recovery, which you can find on the downloads section.
For installing the recovery:
- Boot into download mode as described below
- Press the volume up button a single time to fully enter download mode
- Connect your device to your computer
- Once you are in download mode, open Odin and make sure that it detects your device
- Go to options on Odin, and disable auto-reboot (DO NOT ENABLE ANY OPTIONS OTHER THAN F. Reset Time and Auto-Reboot)
- Download the vbmeta.tar file from the downloads section
- Select on the "Ap" button the vbmeta.tar file and then click "Start"
- Download the recovery.tar file from the downloads section
- Select on the "Ap" button the recovery.tar file and then click "Start"
If Odin gets stuck (specially when flashing recovery.tar), you might try the following:
- After you flash vbmeta, reboot into download again, and directly flash the recovery (once you have flashed the vbmeta once you shouldn't need to flash it again)
- Try a different PC or USB cable
- Try a different version of Odin
Click to expand...
Click to collapse
- Once the flashing completes, power off your device by pressing power + volume down, and after the screen turns off, quickly press the key combination for booting into recovery
- If everything went fine, you should be now on the LineageOS recovery
Warning: if you boot into the OneUI again, it will overwrite the custom recovery and you'll need to install it again!
Step 3 - Installing the ROM
- Download the ROM from the downloads section (make sure you download the .zip file and not the .sha256sum file)
- Once in recovery, go to the "Apply update" section, and click "ADB sideload"
- Connect your device to the computer, and sideload the update with adb sideload path/to/file
An example of the command on Windows can be adb sideload C:\Users\myuser\Downloads\lineage-20.0-20230223-unofficial-gta4xlveu.zip
Click to expand...
Click to collapse
- Your device should start verifying and installing the update
- After the installation has finished, you need to format the data partition (Factory reset -> Format data/factory reset)
- Now, click "Reboot to system"
- If everything went correctly, you should be booting LineageOS
How to boot into recovery/download modes:
Spoiler: Booting into recovery/download
Download
- For booting into download, you will have to press at the same time the power and the two volume buttons until the "Download" screen shows up.
- If you want to boot into download with the device powered on, you have to press the reboot option and right after that, press the key combination as mentioned above.
Recovery
- First, make sure to connect the device to a computer, otherwise the tablet won't allow you to boot into recovery (it's a Samsung restriction).
- For booting into recovery, just press the power and volume up buttons. Once the Samsung logo / bootloader unlocked warning has appeared, you can release the buttons and press the power button to skip the warning screen.
- Just like with the download mode, if you want to boot into recovery with the device powered on you just have to press the keys right after pressing the reboot button.
DownloadsAll files (ROM, recovery and vbmeta) are available at https://files.danielml.dev/android/gta4xlveu/.
Both models (WiFi and LTE) are compatible with the same ROM zip (gta4xlveu).

Thank you very much, i will test it next week.

Testing out the new ROM, glad to see one for the Qualcomm 2022 version.
Battery stats works
Camera works
Using lawnchair 2 and it works! Pixel keeps crashing (?)
Thanks!

Glad to see that you liked the ROM.
Here Pixel launcher works, not sure why it doesn't there.
Anyways, I'll remove GApps by default on future builds so the Pixel launcher won't be present. (Of course, you'll be able to install a custom GApps package).

Thank you! Also started to test now. I disabled most of google app from the start and went fdroid/aurora way (waiting with anticipation for no google version). Nothing crashed yet.

btw, how to root this image? is patching boot.img and replacing it in zip and then flashing as above enough, or is there any changes required for vbmeta?

Well, I didn't try, but just flashing Magisk *should* be enough.

unfortunately this method does not work: during sideload it fails with `Unable to repack boot image` and recovery logs are somehow empty, but still managed to boots after this error
i will try with patching boot.img when i will have more time

ok, i managed to flash image with patched boot.img (extract zip, uload boot.img to device, patch with magisk, download patched boot.img, remake zip image),
but just flashing patched image from recovery made my existing system unbootable
and i had to reflash stock firmware and then repeat flashing steps from scratch
(flash vbmeta/recovery, and then flash patched image),
with this the device is booting and root is working
notes:
- the unbootable state from above was device going into black screen just after samsung logo, with no hints of activity (10 min was max i waited)
- only pressing all tree keys (power, volume up and down) made it reboot with about one second of turn off state (so one can't actually power off the device, it just boots up again into black screen after logo)
- after reboot i was not able to enter recovery or download mode by just pressing known combinations of buttons, and the only way to enter download mode was: during this 1 second power off state to press volume up and down keys and connect usb cable (spend some time finding this solution)
- during flashings after uploading vbmeta i could not flash recovery right after vbmeta (it gets stuck during upload) and i had to reboot again into download mode and then flash recovery (this happened both during my first try to install this image, and with the patched image)
- for some reason in this image i have two sets of navigation buttons at the bottom of the screen (the triangle, circle and square buttons), one is standard android set and one compressed to the right side of nav.bar; stopping pixel launcher removes the compressed one, but the square button (task switching) stops working
- after installing patched image i also noticed (in hindsight) that actually during first install the scroll was very choppy (and the system was kind of slow), but in second install this problem went away

Thanks a lot for the ROM. The following steps for rooting lead to success for me:
1. flashing according to the instructions as described by daniml3.
2. copy Magisk 25.2 to the external SDCARD and rename to .zip
3. reboot in recovery
4. factory reset -> format data/factory reset
4. do not boot, but install Magisk from tablet via ADB from SDCARD
5. reboot
6. rename magisk to .apk again and install the app
7. set up Magisk
8. after reboot be sure to complete ANDROID setup
It rocks!
The navigation buttons are also duplicated for me.
I hope I could help.
I wish a LineageOS without Google.

Thanks everyone for the feedback! There are a few notes:
- I'll release a version without Google Apps as soon as possible (most likely this weekend).
- The lag when booting is caused due to some overlay issue, I still have to look into it, but as it doesn't affect much to the functionality after a few seconds its not a "priority".
- The duplicated navigation buttons are actually an issue from the Google Apps (maybe the Pixel Launcher?). This will be fixed with the Google app-less version of the ROM. If you switch to gesture navigation this issue dissapears.

Is there a possibility for SM-P619 LTE version?

As I said on the post, if you have the LTE model, and want to try a build, just let me know (preferably by Telegram).

Uninstalling the pixel launcher via adb removes the extra icons.
Small lag at start-up but other wise a smooth-running rom.
Thanks!

Today (if everything goes as planned) I'll publish a new update for the WiFi-only model, including:
- Enforcing SELinux
- Removed GMS by default (you can install them as a separate package, personally BitGapps worked perfectly)
- Fixed some background services crashing
This will probably be the last update in a (few) week(s), as I'm working on an source-built-vendor device tree, which may take some time.
I'm also working on a build for the LTE variant, which will be published as soon as I verify that it works correctly.

At the moment I am not at home. After my short vacation I am looking forward to try it at the end of the week.
Many thanks for your work.

A new update for the SM-P613 (gta4xlvewifi) was published just now with the following changes:
- Enforcing SELinux
- Removed GMS by default (you can install them as a separate package, personally BitGapps worked perfectly)
- Fixed some background services crashing
Download it at https://sourceforge.net/projects/gta4xlve-dev/files/gta4xlvewifi/lineage-20.0/
Warning: If you used GMS, you'll need to manually install them (I use BitGapps and they work correctly).

Latest update runs really smooth with bitgapps. Lawnchair works with no problems. Thanks again for this ROM!

Bit of a stretch to ask, but would it be possible for the build to identify itself as a tablet, rather than a phone? And the possibility of defaulting the orientation to landscape? (90 degree rotation as default rather than 0)

Introduction
LineageOS, an open-source Android distribution, is available for several devices,
with more being continuously added thanks to the biggest, yet ever growing, Android open-source community.
Join us and breathe new life in your device, be it old or new.

Click to collapse
To find out more about LineageOS visit the official Website.
All the source code for LineageOS is available in the LineageOS Github organization. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.
Installation
Warning: These instructions only work if you follow every section and step precisely.
Do not continue after something fails!
Basic requirements
Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
Make sure your computer has adb and fastboot. Setup instructions can be found here.
Enable USB debugging on your device.
LineageOS is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!
Warning: Before following these instructions please ensure that the device is currently using Android 13 firmware.
If the vendor provided multiple updates for that version, e.g. security updates, make sure you are on the latest!
If your current installation is newer or older than Android 13, please upgrade or downgrade to the required version before proceeding (guides can be found on the internet!).
Unlocking the bootloaderNote: The steps below only need to be run once per device. They require a machine running Windows 7 or newer.
Warning: Unlocking the bootloader will erase all data on your device! Before proceeding, ensure the data you would like to retain is backed up to your PC and/or your Google account, or equivalent. Please note that OEM backup solutions like Samsung and Motorola backup may not be accessible from LineageOS once installed.
Tip: It is highly recommended to have the latest official MIUI stable package installed on the device, before proceeding with unlock.
Create a Mi account on Xiaomi’s website. Beware that one account is only allowed to unlock one unique device every 30 days.
Add a phone number to your Mi account.
Insert a SIM into your phone.
Enable developer options in Settings > About Phone by repeatedly tapping MIUI Version.
Link the device to your Mi account in Settings > Additional settings > Developer options > Mi Unlock status.
Download the Mi Unlock app (Windows is required to run the app).
Run the Mi Unlock app and follow the instructions provided by the app. It may tell you that you have to wait up to 30 days. If it does so, please wait the quoted amount of time before continuing to the next step!
After device and Mi account are successfully verified, the bootloader should be unlocked.
Since the device resets completely, you will need to re-enable USB debugging to continue.
Flashing additional partitionsWarning: This platform requires additional partitions to be flashed for recovery to work properly, the process to do so is described below.
Download the following files from the download section below.
boot.img
dtbo.img
vendor_boot.img
Power off the device, and boot it into bootloader mode:
With the device powered off, hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
Flash the downloaded image files to your device by typing (replace <...> with the actual filenames!):
fastboot flash boot <boot>.img
fastboot flash dtbo <dtbo>.img
fastboot flash vendor_boot <vendor_boot>.img
Booting a custom recovery using fastboot
Download Lineage Recovery from the download section below. Simply download the latest recovery file, named recovery.img.
Important: Other recoveries may not work for installation or updates. We strongly recommend to use the one linked above!
Connect your device to your PC via USB if it isn’t already.
If your device isn’t already in fastboot mode, on the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
adb reboot bootloader
You can also boot into fastboot mode via a key combination:
With the device powered off, hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
Once the device is in fastboot mode, verify your PC finds it by typing:
fastboot devices
If you don’t get any output or an error:
on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable (preferably use a USB Type-A 2.0 one or a USB hub) and port!
Tip: Some devices have buggy USB support while in bootloader mode, if you see fastboot hanging with no output when using commands such as fastboot getvar ..., fastboot boot ..., fastboot flash ... you may want to try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub.
Flash a recovery on your device by typing (replace <recovery_filename> with the actual filename!):
fastboot flash recovery <recovery_filename>.img
Note: Outdated fastboot releases dropped legacy A/B support, so it might attempt to flash to recovery__a /recovery__b rather than recovery_a / recovery_b if you try to flash recovery. In this case, you must update fastboot to a release newer than or equal to 31.0.2. Alternatively, you can manually specify which slot to flash to based on what slot fastboot failed to flash to. For example, if fastboot fails to flash to recovery__a, you must flash to recovery_a.
Now reboot into recovery to verify the installation.
With the device powered off, hold Volume Up + Power. Keep holding both buttons until the “MI” logo appears on the screen, then release.
Note: If your recovery does not show the LineageOS logo, you accidentally booted into the wrong recovery. Please start at the top of this section!
Installing LineageOS from recovery
Download the LineageOS installation package from the download section below that you would like to install or build the package yourself.
(Optionally): If you want to install an application package add-on such as Google Apps (use the arm64 architecture), please read and follow the instructions on Google Apps page
If you are not in recovery, reboot into recovery:
With the device powered off, hold Volume Up + Power. Keep holding both buttons until the “MI” logo appears on the screen, then release.
Now tap Factory Reset, then Format data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage.
Return to the main menu.
Sideload the LineageOS .zip package but do not reboot before you read/followed the rest of the instructions!
On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
On the host machine, sideload the package using: adb sideload filename.zip.
Tip: Normally, adb will report Total xfer: 1.00x, but in some cases, even if the process succeeds the output will stop at 47% and report adb: failed to read command: Success. In some cases it will report adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.
All set!Once you have installed everything successfully, you can now reboot your device into the OS for the first time!
Click the back arrow in the top left of the screen, then “Reboot system now”.
Note: The first boot usually takes no longer than 15 minutes, depending on the device. If it takes longer, you may have missed a step, otherwise feel free to get assistance.

This thread is for discussion about the build from a user-perspective while the other thread aims to bring the build process closer to other developers and discussion about the source code.
GApps situation on the vanilla build is still the same but i have also built one with google apps integrated.
The relevant files can be downloaded here.

Gapps.
Yep, I had seen it but it dated back to February and now it's up to date.
You worked hard, thanks.

God bless you

Nice working bro.
Waiting for too long to use the stable aosp ROM

I have created a magisk module to get the MiuiCamera application working on LineageOS.
I missed two libs in vendor which are meant to be in the ROM, i have added them into the magisk module for now so that bokeh mode works.
If the module does not work for you please run the following commands, clear the app data and reboot
Code:
adb shell restorecon vendor/lib64/libmibokeh_mask.so
adb shell restorecon vendor/lib64/libmiphone_capture_bokeh.so
edit:// seems like you need to clear the apps data everytime you use the app. I forgot to include the fix in source of the ROM. The next lineage build will fix this issue!
Please use v1.08 on builds that are newer than 20230625.

Thank you for your efforts！

Thank you! You made this device 10x better!

First of all superb job on first AOSP rom for Zeus, or atleast what I know. Nearly perfect from the start. However I've noticed very minor bugs (wont affect use) like time untill fully charged on lockscreen is missing 2nd digit of the time and back gesture doesnt work properly when keyboard open (I'm using GSM release so I have GBoard). Other than that I've found 0 major issues so far and everything seems to work as it should. Keep up the good work, and THANKS for saving Xiaomi 12 Pro.

Battery usage seems to be reported wrongly, not a big deal.

Few issues so far:
AptX Adaptive bluetooth codec doesn't seem to be present at all
Brave Browser (could also be any chromium based browser but unsure) freezes once in a while and completely dies with Sync Chain on (also read this might be a Magisk issue so this may be unrelated)
There are a few stutters and lag spikes here and there when the screen is transitioning to 120Hz
No way to change resolution to 1080p to save battery life
Either way, amazing work and thank you for everything!

I have the same issue when using browser to view page with too much text or js. I have solve by deactivating the auto frame rate, it makes my screen 60 Hz always. I think the problem is cause of kernel.

Forgot a few:
Sometimes a random flicker occurs at the left side of the status bar, very weird graphical issue (Was downloading songs from Tidal during this)
Animations and UI elements that are usually tied to where the physical buttons are (volume slider, AOD off animation) are not placed correctly
Sorry if these are issues already known or to be considered as cherry pick issues!

GMS version:
Connecting earphones to usb, the headphone icon is displayed but indicates that the device is charging.
Only the links sent by my banking application on Google messages are inactive (not this problem with the previous version 20230606).
The association of my GTR4 require 2 Bluetooth associations, concerning the second,for calls, the code is indeed sent to the watch and the phone but during the association, it returns a second code, which causes the association to fail (same on the previous version).
Browser freeze more frequent than the previous version.
Call recorder"Basic Call Recorder" (Magisk) works perfectly.
Basic Call Recorder is a no-nonsense call recording solution for rooted devices
Thanks to this Magisk module, you can now enable the call recording feature on any Android device running Android 10-13. Read on!

Introduction
To find out more about LineageOS visit the official Website.
All the source code for LineageOS is available in the LineageOS Github organization. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.
Installation
Warning: These instructions only work if you follow every section and step precisely.
Do not continue after something fails!
Basic requirements
Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
Make sure your computer has adb and fastboot. Setup instructions can be found here.
Enable USB debugging on your device.
LineageOS is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!
Warning: Before following these instructions please ensure that the device is currently using Android 13 firmware.
If the vendor provided multiple updates for that version, e.g. security updates, make sure you are on the latest!
If your current installation is newer or older than Android 13, please upgrade or downgrade to the required version before proceeding (guides can be found on the internet!).
Unlocking the bootloaderNote: The steps below only need to be run once per device. They require a machine running Windows 7 or newer.
Warning: Unlocking the bootloader will erase all data on your device! Before proceeding, ensure the data you would like to retain is backed up to your PC and/or your Google account, or equivalent. Please note that OEM backup solutions like Samsung and Motorola backup may not be accessible from LineageOS once installed.
Tip: It is highly recommended to have the latest official MIUI stable package installed on the device, before proceeding with unlock.
Create a Mi account on Xiaomi’s website. Beware that one account is only allowed to unlock one unique device every 30 days.
Add a phone number to your Mi account.
Insert a SIM into your phone.
Enable developer options in Settings > About Phone by repeatedly tapping MIUI Version.
Link the device to your Mi account in Settings > Additional settings > Developer options > Mi Unlock status.
Download the Mi Unlock app (Windows is required to run the app).
Run the Mi Unlock app and follow the instructions provided by the app. It may tell you that you have to wait up to 30 days. If it does so, please wait the quoted amount of time before continuing to the next step!
After device and Mi account are successfully verified, the bootloader should be unlocked.
Since the device resets completely, you will need to re-enable USB debugging to continue.
Flashing additional partitionsWarning: This platform requires additional partitions to be flashed for recovery to work properly, the process to do so is described below.
Download the following files from the download section below.
boot.img
dtbo.img
vendor_boot.img
Power off the device, and boot it into bootloader mode:
With the device powered off, hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
Flash the downloaded image files to your device by typing (replace <...> with the actual filenames!):
fastboot flash boot <boot>.img
fastboot flash dtbo <dtbo>.img
fastboot flash vendor_boot <vendor_boot>.img
Booting a custom recovery using fastboot
Download Lineage Recovery from the download section below. Simply download the latest recovery file, named recovery.img.
Important: Other recoveries may not work for installation or updates. We strongly recommend to use the one linked above!
Connect your device to your PC via USB if it isn’t already.
If your device isn’t already in fastboot mode, on the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
adb reboot bootloader
You can also boot into fastboot mode via a key combination:
With the device powered off, hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
Once the device is in fastboot mode, verify your PC finds it by typing:
fastboot devices
If you don’t get any output or an error:
on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable (preferably use a USB Type-A 2.0 one or a USB hub) and port!
Tip: Some devices have buggy USB support while in bootloader mode, if you see fastboot hanging with no output when using commands such as fastboot getvar ..., fastboot boot ..., fastboot flash ... you may want to try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub.
Flash a recovery on your device by typing (replace <recovery_filename> with the actual filename!):
fastboot flash recovery <recovery_filename>.img
Note: Outdated fastboot releases dropped legacy A/B support, so it might attempt to flash to recovery__a /recovery__b rather than recovery_a / recovery_b if you try to flash recovery. In this case, you must update fastboot to a release newer than or equal to 31.0.2. Alternatively, you can manually specify which slot to flash to based on what slot fastboot failed to flash to. For example, if fastboot fails to flash to recovery__a, you must flash to recovery_a.
Now reboot into recovery to verify the installation.
With the device powered off, hold Volume Up + Power. Keep holding both buttons until the “MI” logo appears on the screen, then release.
Note: If your recovery does not show the LineageOS logo, you accidentally booted into the wrong recovery. Please start at the top of this section!
Installing LineageOS from recovery
Download the LineageOS installation package from the download section below that you would like to install or build the package yourself.
(Optionally): If you want to install an application package add-on such as Google Apps (use the arm64 architecture), please read and follow the instructions on Google Apps page
If you are not in recovery, reboot into recovery:
With the device powered off, hold Volume Up + Power. Keep holding both buttons until the “MI” logo appears on the screen, then release.
Now tap Factory Reset, then Format data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage.
Return to the main menu.
旁加载 LineageOS .zip 包，但在阅读/遵循其余说明之前不要重新启动 ！
在设备上，选择“应用更新”，然后选择“从 ADB 应用”以开始旁加载。
在主机上，使用 adb sideload filename.zip 旁加载包。
提示： 通常情况下，adb 会报告 Total xfer: 1.00x，但在某些情况下，即使进程成功，输出也会停止在 47% 处并报告 adb: failed to read command: Success。在某些情况下，它会报告 adb: failed to read command: No error 或 adb: failed to read command: Undefined error: 0 这也可以。
可以了，好了！成功安装所有内容后，您现在可以首次重新启动设备进入操作系统！
单击屏幕左上角的后退箭头，然后单击“立即重新启动系统”。
注意： 首次启动通常不会超过 15 分钟，具体取决于设备。如果需要更长的时间，您可能错过了某个步骤，否则请随时寻求帮助。

版本在此处发布：GitHub 上的版本
警告：这些版本包括针对我拥有的其他设备的构建，请确保从小米 12 的版本下载文件，例如：“ LineageOS 20.0 forxiaomi 2201122G (zeus) ”
注意：有两个变体不一定同时发布。Vanilla 版本是纯粹的 LineageOS，无需额外的应用程序，而 GMS 版本则包含 Google 服务。GMS 版本对于 github 版本来说太大，因此它们将被上传到Google Drive 上的此共享文件夹

Beberapa masalah sejauh ini:
AptX Adaptive bluetooth codec sepertinya tidak ada sama sekali
Peramban Berani (bisa juga peramban berbasis krom apa pun tetapi tidak yakin) membeku sesekali dan benar-benar mati dengan Rantai Sinkronisasi aktif (baca juga ini mungkin masalah Magisk jadi ini mungkin tidak terkait)
Ada beberapa gagap dan lonjakan lag di sana-sini saat layar beralih ke 120Hz
Tidak ada cara untuk mengubah resolusi ke 1080p untuk menghemat masa pakai baterai
Either way, kerja luar biasa dan terima kasih untuk semua
