Hi There,
I hope someone can advise and possibly provide help resolving this problem.
The Moto G4 is not able to boot to OS, It only boots into bootloader, cannot go into recovery and cannot go into Factory Mode etc.
The error i get on the phone is....
"Start Up Failed"
Failed to verify hab image boot
Failed to verify boot image
ERROR: Failed to pass validation, backup to fastboot
Fastboot Reason: Fall-through from normal boot mode
I have tried to clear fb_mode and tried to unlock the bootloader without success.
I have tried various stock roms to get this fixed. The phone has never been unlocked and not been rooted.
