LineageOS is a free, community built, aftermarket firmware distribution of Android 10, 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:

  • Make sure you're already unlcoed your bootloader
  • Make sure you're already flash Lineage Recovery made by me
  • Reboot to recovery
  • flash lineageos build
  • flash "stock-a71n" zip ( i will explain it why in second post
  • flash gapps
  • reboot
If you gapps, magisk or any zip showing "failed to mount system" please reboot the recovery.

Downloads:



Known issues:
Fingerprint not working
Wireless Earphone not working



Reporting Bugs:

  • Make sure the bug you want to report isn't already known
  • DO NOT Report bugs if you're running a custom kernel or you installed Xposed
  • 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.

Here is the current situation. I've made this ROM running with stock vendor, so that we need to use stock "image kernel" to works.
if you're curious to know what will happen if you're not using stock "image" kernel i am allowing you to not flash "stock-a71n.zip"


feel free to contribute to this project.

Awesome. i just tried it out on my Samsung galaxy a71 and everything seems to be working OK. however i have noticed a few small issues. the proximity sensor when making phone calls does not work and double tap to wake is not present in settings. also the WiFi network signal is rather weak compared to the Stock Rom. if you need me to send over some logs i would be happy to

Crap OS.....it's not that bad.....

Trust me it is, I have 8gb ram variant and the ui is laggy AF, I can only run 4 apps on the memory more than that it will start closing apps and refreshing. So much lag with gestures, recent menu, notification panel, games runs slower than my xiaomi mi a2 which has sd 660!!

I've downloaded the latest official A71 build via Frija, took your Recovery.img (made it a tar / tar.md5 file), added it to AP in Odin (the other files are from the Frija download - although, in my despair, I tried just to flash the recovery file on its own ?) --> "recovery error" when booting up.

Made it only once to your recovery, wipe/..., flashed the Lineage os build, the stock-A71n-zip, plus the gapps from sd card... when trying to reboot, same recover error messages as before.

you're not read it properly. it stated you need to use oneui 2.0 U2. you haven't unlocked and disable vbmeta aren't you?

I''m sorry, but I have no idea, if I've done something to vbmeta. Just unlocked the bootloader and followed the steps explained earlier. Before I make another mistake: you (yep, already in your first post, I noticed it just now) mentioned a "U2 OneUi 2.0" firmware... My plan was to just download an oneui 2.0 build without thinkin 'bout the "U2...". Which exact firmware do I have to use? And THANK YOU for your help.
Will this be ok? https://boycracked.com/portfolio/sm-a715f-ds-firmware-for-samsung-galaxy-a71-in-europe/
