I'm very familiar with installing TWRP on a new Samsung phone. But this time it's not working, and I don't know why.
The phone is a Samsung S9+ (SM-G965F). Bootloader unlocked, data wiped and reformatted. All confirmed. Odin is working. I can flash lastest TWRP with odin, and reboot into it at first reboot. So far everything is as normal.
It should offer an option to prevent the stock rom from replacing it with the default recovery, or automatically do so. But whatever I do, it doesn't happen. First reboot to system, and I go back to default recovery. Things tried:
- flash TWRP -> reboot directly to TWRP -> select "allow mods" -> reboot to system. (This has always been all that's needed, before now)
- flash TWRP -> reboot directly to TWRP -> select "allow mods" -> flash multidisabler (never had to use that before) -> reboot to system
What am I missing? Why isn't it working? What else should I do?
