[Moto Z2 Play  Questions & Answers] rembick:
Hello guys,

I need a help. I was trying to update my moto using this thread: https://xdaforums.com/z2-play/how-to/fastboot-rom-oreo-retail-via-fastboot-t3786153

Everything seemed to be fine until the restart. Phones starts imidately in Fastboot mode with ERROR: Failed to pass validation, backup to fastboot. Now I can't do anything. I've tried to flash other roms, using also that thread: https://xdaforums.com/z2-play/how-to/close-bootloader-lineageos-losing-imei-t3769479 but during the installation it gives many error about downgrading to older security version. Any Ideas? I was trying to find blanckflash but qboot doesn't see the phone. What can I do with that?

with command getvar all I get this. Maybe it will be helpfull.
