I got the FP6 and manually installed /e/os and it went smoothly, but when I wanted to go to Android 15 I followed the instructions written on the fairphone website and it went smoothly until the final step that stated to lock the bootloader.
Before locking the bootloader the phone booted into android 15 without any issues however the moment I locked the bootloader the phone refused to boot into android 15 and I tried everything from:
Trying to unlock the bootloader and reinstalling android 15
Removing the battery
Restarting the phone
Countless commands in the terminal
All resulted with the same issue, returning to the bootloader.
Can anyone please help with this issue?
