About LineageOS

LineageOS is a free and open-source operating system for set-top boxes, smartphones and tablet computers, based on the Android mobile platform. It is the successor to the custom ROM CyanogenMod, from which it was forked in December 2016 when Cyanogen Inc. announced it was discontinuing development and shut down the infrastructure behind the project. Since Cyanogen Inc. retained the rights to the Cyanogen name, the project rebranded its fork as LineageOS.

LineageOS was officially launched on December 24, 2016, with the source code available on GitHub. Since that time, LineageOS development builds now cover more than 185 phone models with over 1.9 million active installs,having doubled its user base in the month February–March 2017 And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

Is step #5 really necessary? If in step #1 a fastboot ROM is used it already contains the firmware.

Also what's the status on SeLinux and SafetyNet?

Very nice and good job!

Hello Compass,

Step #5 isn't necessary to do so, but some users ping about the brick they faced while shifting from any other rom so i usually Suggest Users to flash FW too

For now SELinux is permissive & Cts fails by default but can be fixed using mods & hide props.

I hate Android 11/12 but this looks promising.

Also can't we just use Dynamic TWRP? (Yes we can)

Installed it and the issues are:

1)From restoring a backup,it may say it can't contact google servers,in that case re-login and it should be solved.

2)I can't find OEM unlocking in the settings

3)Can't change button shortcuts.They always stay the same

Also DON'T use UnicornHorn Kernel on this ROM due to the Android version,though you'll most likely end up in a soft-brick (Learned that the hard way)

Im so curious about battery life. I've tried couple of A12 rooms for N8P and all of them had the worst battery stats. I would only get 3and half SOT which is so bad.

Based on my experience,it's better than MIUI 12 (no battery drainage happened to me in both versions)

Hello! How to build this ROM? Is there an instruction?

 

[Spleeny97]

Hi my wifi sharing connection is connected but cannot access internet
Notifications works, Facebook app too, but Chrome doesn't neither Google Play store
So weird...

 

[Inled]

Why is "Material You" theming system not working? Is this something about this particular ROM? Or is it an app problem? Or is it just for me?

 

[Spleeny97]

Can someone help ?

Hello, I've tested the ROM and it looks good 'till now. The only problems I had were:
- first time I've installed it from stock ROM (MIUI 12.5.x) I've soft-bricked it (dunno how) - [after installing the ROM]. I couldn't get to the recovery. I mean, I've got there, but the slider didn't showed up (only the twrp banner), stayed like this for ~1 min and then automatically rebooted and then back again and so on. I've unbricked it by reflashing `boot.img` (I could get into fastboot mode). Still, after reflashing I couldn't get to the recovery (same story but not bootloop).
P.S: I've also tried a dozen other TWRPs, none worked.

I've installed the stock ROM again and reinstalled the custom one (this time the recovery problem is not present, I can access TWRP now).
- It lags a bit sometimes, for instance when you unlock it and move between screens.
- Can't adjust the volume of call when on speaker (it stays the same - loud enough).

I would like to know how to set SELinux to enforcing. `echo 1 > /sys/fs/selinux/enforce` didn't worked out.

Edit: Also, alongside the SELinux notification that pops up when the phone starts, I get another notification from Trust that says that this build was signed with public keys.

Update: I've managed to set SELinux to Enforcing mode by editing this Magisk module, but...
1. The fingerprint sensor didn't worked after that
2. Files app crashed at open
3. Couldn't take screenshots
and probably there were more issues to be discovered.

I wouldn't suggest enabling SELinux on this ROM because it's doesn't work properly. Try using Dynamic TWRP for the recovery and flash a fastboot stock ROM instead of recovery ROM because recovery ones do not contain the proper firmware.
