Hmm , after downgrading tab encrypting data started , after that stuck in bootloop.
Oh, I hope you have a backup of your data... Can you at least access them from TWRP?
By the way, is there a reason to downgrade to Android 10? If it's because of random freezes, I've probably fixed them (it hasn't happened to me for 2 days yet) and I'm going to upload the update in a few days.

Yes i had already taken the backup , random freeze happens but rarely.
Main reason to downgrade is low memory(ram).
Edit : i always use bitgapps instead of opengapps.

Download
  • September 2022 security patch.
  • Reverted unneeded CAF merge in kernel.
  • Merged wlan driver with LA.UM.7.6.2.c25 (should fix random kernel panics and freezes).
Hello Dev,

I tried this rom and Lineage rom with the same problem. I used it normally and have a random freezes.

I tried to wipe all and reinstalling with the same result.

I use flameapps.

Thx!

Are you sure that you're using the latest build? I have had the latest build booted for a week without a reboot and it hasn't happened yet.
You can try to get logs by rebooting to TWRP after the freeze happens and then run on your computer:
Code:
adb shell cat /sys/fs/pstore/console-ramoops

Hi, I got another set of logs from the device crashing earlier today...
Edit: This was taken immediately after the crash unlike the other one, which was taken a few minutes later...

Thanks for sending the logs. It seems that the kernel panic is caused by SELinux denials spamming the kernel. Try to boot the ROM, log in as root and execute setenforce 0 and if this is the case, it shouldn't crash.

Is it a good idea, setting selinux to permissive...
Edit: can I use a magisk module to do it?
Edit 2: I'll try it for a day and I'll let you know...
