[Moto G Power Questions & Answers] Constantinologia:
I have the same problem. Tried to install a stock rom, then i did "fastboot oem lock", now i get the message "your device is corrupted. It cannot be trusted and will not boot". In the Fastboot Flash Mode it shows "Flashing... Locked".

Tried to run Fastboot oem unlock <Code Provided>, but i get the error:

(bootloader) Check 'OEM unlocking' in Android Settings > Developer

(bootloader) Options

FAILED (remote failure)

finished. total time: 0.011s

Tried to boot most recent Stock Rom, but get "Permission Denied" errors.
