LineageOS is a free, community built, aftermarket firmware distribution of Android 12, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

Instructions:
  • Follow the instructions here

Downloads:

Reporting Bugs
  • DO NOT Report bugs if you're running a custom kernel or you installed Xposed
  • DO NOT Report bugs if you're using TWRP
  • Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
  • If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
  • If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log

Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.

Requirements:
  • Any R based firmware installed on your device.

Pre-Install Instructions

Warning: The following instructions will unlock the bootloader and wipe all userdata on the device.

  1. Connect the device to a Wi-Fi network.
  2. Enable Developer Options by pressing the “Build Number” option in the “Settings” app within the “About” menu
    • From within the Developer options menu, enable OEM unlock.
  3. Power off the device, and boot it into download mode:
    • With the device powered off, hold Volume Down + Volume Up and connect USB cable to PC.
    • Now, click the button that the onscren instructions coorelate to “Continue” and/or “Unlock Bootloader”.
  4. Your device will reboot, you may now unplug the USB cable from your device.
  5. The device will demand you format userdata, please follow the onscreen instructions to do so.
  6. Run through Android Setup skipping everything you can, then connect the device to a Wi-Fi network.
  7. Re-enable Development settings by clicking the “Build Number” option 10 times, in the “Settings” app within the “About” menu, and verify that “OEM Unlock” is still enabled in the “Developer options” menu.

Installing LineageOS for the first time
  1. Flash lineage recovery
    Only the provided lineage recovery will be supported,
    using TWRP might result in a possible data loss!!

    If using Odin rename the lineage recovery image for your model to recovery.img and add it to a .tar archive using e.g 7zip.
    If using Heimdall use: heimdall flash --RECOVERY recovery.img --no-reboot
  2. Boot lineage recovery
    IMPORTANT: Do not boot into system again before booting recovery, or system will restore stock recovery!
    If using Odin untick auto-reboot before flashing.
    After flashing reboot by pressing Volume Down and Power for approximately 7 seconds,
    immediately hold Volume Up and Power to boot recovery
    IMPORTANT: As of OneUI 3 your device needs to be connected to a PC via USB cable in order to be able to
    boot recovery via Volume Up, Bixby and Power.
  3. Factory reset using Factory reset -> Format data/factory reset
    Warning: Unlike TWRP this will also erase internal storage!
  4. Sideload LineageOS by enabling sideload via Apply Update -> Apply from ADB
    Then run adb sideload <path to your lineage.zip> on your PC
    Optional:
  5. Sideload GApps and magisk by repeating above step
    with their zip/apk

Magisk
I strongly recommend to use Lygisk instead,
which is a fork of Magisk that aims to improve support for devices with FBE that can't (and shouldn't anyways!) decrypt userdata in recovery,
this will also fix OTAs getting stuck while having installed Magisk.

I am on your unofficial 18 and this just pop up in updater, is it safe to do OTA? Thanks for your efforts!

Always follow this rule of thumb: it is never safe to dirty flash a completely different build on top of an older build (i.e. flashing 19.0 on top of 18.1, or 18.1 on top of 17.1, etc.). At best, you'll find yourself having random problems all over the place; at worst, the ROM will refuse to load. Best thing to do whenever going from one major release to another (or from one completely different ROM to another) is backup your apps and data, wipe data and caches and perform a clean flash, then restore your apps and data. It's a fair bit of work, to be sure, but it's the best way to avoid problems.

Sim card dont work, IMEI dont show, gapps cant install. Any ideas?
About the SIM issue, there's two things:
1. (more likely) You flashed the wrong build (gta4xlwifi instead of gta4xl) or in other words, flashed the WiFi only version firmware.

2.(Unlikely but could happen) You corrupted your baseband somehow as I had a similar situation with my Redmi Note 9 with a corrupted baseband so basically the IMEI was all zeros. That was also the reason why the SIM card didn't work.
You could try to install the original firmware with odin and check functionality and try again.

About the gapps issue

Did you install it for the correct architecture (arm64 not arm)?
Does it show error messages?

With the latest build, it's all fixed!

Installed Lineage 19 last weekend on my P-610. You can flash the rom.zip, GApps and Magisk in Recovery from SD-card, so no need to sideload with adb. I have a problem with Google Playstore, it lags a lot (pending...) and installing an app like Gmail takes a long time. Now it even stopped working. Will try it later with NikGApps for Android S

Hi, it seems audio is not working.
It's just me?
Any help please.

M

Are you on today's build already?
If so try again with that please - your device might be hw revision 9 which uses different audio drivers and wasn't supported in my kernel until today
Also could check the output of adb shell getprop ro.boot.revision to confirm it's rev 9

First of all, I want to say thank to @Linux4 for this release :) Secondly, I want to ask comrads how to install MicroG on this build? If you can step by step, I'm new to custom firmware :)

Working nicely, I'm currently getting a weird issue with the 2021-11-27 gta4xl build.

It's extremely weird but with quiet songs there's some kind of audio ducking going on.
Song it was most obvious on was Air - Bad and Sad 4.2 Vagabond Demo for example but it sounds like it's trying to cut out the audio or something.

Device was bought a few days ago so I'm guessing it'll be the latest hw revision.

I have the same thing with any sound on the tablet :( This is especially noticeable when playing songs on spotify.
