I am on DUJ5 Firmware (last Android 11) on G981B (S20 5G) and am trying to use this tutorial to get to the last Android 12 version. In order to do so, I first want to upgrade to the first Android 12 Firmware for the S20 (EUL7) and in a second step from there to the last one (FVIB).
But already at the first upgrade I get into a bootloop, even though I follow the instructions step by step:
- Put AP, BL, CP files in their Odin slots.
- Put HOME_CSC file in CSC slot
- Put vbmeta_disabled file in USERDATA slot
-> press START and flash.
Already at this point, rebooting results in a bootloop. Luckily I can get back to DUJ5 by reflashing that, but the update won't work. I completely uninstalled Magisk from DUJ5 and tried the whole procedure again, resulting in a bootloop again.
Any ideas, anyone?
