FASTBOOT MODE LOCKED

[eirick1]

My phone is stuck on the fastboot mode screen, with error messages in DEVICE STATE: ERROR! and NOS PRODUCTION: ERROR! (-7)
HOW CAN I FIX IT?
All the options I can use with the volume up or down return to the FASTBOOT MODE screen, and I'm in infinite looping.

Ty for help me

try this command to enter in recovery mode
fastboot reboot-recovery
if it enters in recovery mode then you can flash firmware via adb sideload method.
