Hi all! I tried to flash 5.1 retus on a 5.0.2 retla variant (as the tutorial said it would work on all variants, and both are for XT1527) without unlocking the bootloader.
Sadly it won't boot (boots directly to bootloader) and can't go back to stock.
It says: 'version downgraded for boot' 'failed to validate boot image'
This is a problem because everything I find about it says that I should either unlock the bootloader or find a newer retla ROM to flash over. Sad part is that this version is not coming any soon.
I tried to unlock bootloader afterwards but since I've never checked the option inside Dev Options this is like a no-go.
Any ideas?
