Hello Brother, I am facing an issue which is error 7 while trying to flash your rom. I have twrp installed and everything setup, need your help. I also tried to check the Assert line in the extracted files from the "updater-script" but could not find it. Any help would be appreciated!!!

    If anyone face issue like me. please remove screen lock/pin/password before flashing new kernel. I was unable to unlock the phone though I was entering correct PIN. I tried restarting, clearing cache but nothing worked.

    Then I found a solution to remove the password through twrp without deleting or formating your phone.

    Reboot to twrp and go to advanced>file explorer and go to /data/system folder;
    delete these files:

    • password.key
    • pattern.key
    • locksettings.db
    • locksettings.db-shm
    • locksettings.db-wal
    and reboot to recovery. you will be able to unlock your phone without any password. (No data loss).
    this is really helpful even for those who forgot their PIN/password/pattern.
    Thanks for the guide mate or else you can simply flash the pass reset zip file in TWRP and done your lock is removed.
    Currently working on V2 based on latest A50s firmware with August security patch, stay tuned!
    Finally I was able to fix my issue. Thanks to the developer again. here is how I fixed it;
    1) I flashed twrp.tar (for m30s one UI 3.1) in magisk
    2) magisk created a new tar file "magisk_patched-23000_nUMDh.tar" in download folder
    3) I used odin to flash this newly created file in AP.
    4) then go to twrp and reboot to recovery.
    5) done
    thus i was able to obtain stock kernel. AFter this other issues such as logd are gone. CPU usage is also normal.
    Amazing mate :>
    Stock kernal is best! Still I'm trying to build a more powerful kernal for the coming updates.
