FAQ

Reporting Bugs
  • 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.

Code:
What is your--
LineageOS version:

Galaxy Tab S6 Lite WiFi: lineage-17.1-20200923-UNOFFICIAL-gta4xlwifi.zip


INSTALLATION

If coming from stock or the other LineageOS ROM (GSI) you need to format /data with TWRP

Put the ROM zip onto your external sdcard (if you are already on my LineageOS and have decrypted /data you might also put it in internal storage) and flash it using TWRP.

Installed Lineage and it was booting, but had some problems with installing Gapps.
After 3 attempts succeeded with installing Open Gapps pico from sd-card.
In the first 2 attempts, TWRP gave error "failed to mount '/system_root"
I found this: https://github.com/topjohnwu/Magisk/pull/2496 , probably due to dynamic partitions.

Wifi, Bluetooth, pen are working, but gps is not working.

Yes, TWRP's support for dynamic partitions is still not fully finished.
Gps is working for me, but it takes a very long time initializing, that should be fixed with the next update (I'm currently working on including Samsung's september secpatch update on which gps seems to work faster)

It can be changed using an overlay, but that would also change the pointer when using e.g Bluetooth mouse because both use the same pointer. I'll probably add that in the next build.

I think for most people using a mouse is not really important on this device (due to the s pen), thank you very much tho

btw, do I need to clean flash the next build or could I just dirty flash it + magisk when the next build rolls out (I don't particularly like google, so no Gapps for me) ?

Dirty flash should work but you should still make a backup! The other user only had to wipe because gapps failed to install and removing gapps requires a wipe.

Of course, a backup is always important for everything

Will await for your next release then, keep up the good work

on an unrelated note, SElinux is disabled on mine, is it because of magisk or is it because I haven't yet encrypted my device ?
