Having recently received my FP5, I’ve been playing around with it a bit and, above all, I wanted to transfer my data from my old phone.
To do this I use Neo Backup.
It needs root rights to work properly. So I followed the official procedure for unlocking the bootloader, then the instructions in the following post to install Magisk.
Out of ignorance of the risks, I wanted to relock the boot. When I rebooted, I got a warning message saying that the system had been altered and that it would not boot again.
Since then it has been stuck on the bootloader.
I did try to re-unlock the boot with the commands
fastboot flashing unlock
fastboot flashing unlock_critical
But every time I get the message :
FAILED (remote: ‘Flashing Unlock is not allowed’)
Do you have a solution?
Thanks in advance
