Few posts above I have listed my steps for flashing new firmware on my S22 Ultra hoping someone confirm if it should work allowing me to preserve my data.UPDATE - I tried to update to latest update available which is September patch tried first with magisked AP to gain root with no luck (bootloop) again.
....tries again with original AP and it's good to go no problems at all.
I'm starting to think that the problem is from magisk or its necessary to wipe everything
any help is appreciated, knowing that the bootloader is unlocked and been rooted before just need to regain root access without losing data.
Unfortunately no one responded and I followed these steps getting a bootloop. Finally I had to wipe data within stock recovery.
Then i have opened a discussion on Telegram and got this procedure that should work if you don't want to loose data:
Extract vbmeta.img from patched by Magisk AP tar file
Extract recovery.img from TWRP tar file
Create new tar TWRPWithVBMETAPatched.tar from both extracted files vbmeta.img and recovery.img
In ODIN put:
AP stock file into AP slot,
BL stock file into BL slot,
CP stock file into CP slot,
HOME_CSC into CSC slot,
TWRPWithVBMETAPatched.tar file into USERDATA slot.
UNSELECT "Auto reboot" in ODINS' Options tab and start flashing.
When completed reboot into TWRP recovery (Power + Volume Up buttons with phone plugged to PC)
In TWRP run multidisabler in Terminal (if needed twice until Finished is displayed)
The most important step is to reboot into TWRP once the flashing is completed. If you boot into system then you have bootloop.
