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.

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)

Thx, keep up the good work!

 

[Linux4]

I have uploaded an updated version with september vendor security patch which should also fix the gps issues

 

[Iceman66]

Dirty flashed the 0924 version, but i ran into the issue with system_root and got a bootloop.
After format with TWRP, clean flashed from SD-card and booted successful.
GPS is fixed!

 

[Linux4]

I have uploaded a new version which fixes the /system_root mounting issues in TWRP (yes it was caused by LineageOS) but (only for this update, for the next ones it will work without reboot) you will have to reboot to recovery once the update finished to be able to install e.g GApps.

MicroG nanodroid doesn't work yet ? any alternative ?

MicroG nanodroid doesn't work yet ? any alternative ?

I think nanodroid patcher is not supported on Q yet. You can build this rom yourself with signature spoofing patch or you can also use xposed + fakegapps module, but I dont know if it works on Q, you can try it out.

 

[Deleted member 10905451]

Fakegapps with microg via magisk worked wonders

Are there any way to customise the cursor? It's quite hard to see using the default cursor

It don't think it can be changed by user. Btw do you really mean cursor or the pointer used for spen?

The S-pen pointer
I found this guide https://daniel-baker.photography/asus-fonepad-7-change-mouse-cursor/ , but I don't want to revert to stock and don't understand how to extract the image file

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 ?
