Phone stuck in fastboot, no recovery or ROM.

It just did this all the sudden. Seemed to be working fine and then it wont even go into the default recovery.
Worst yet is I just got the unlock code for it, so i could unlock the phone, So that could flash TWRP, and CM12.

Wondering if anyone knew how to unlock and flash from fastboot.

EDIT: Its saying flash failure, but unless it decided to update itself it should not have been flashed.
