I do suspect that the firmware is corrupt as it won't boot into android and none of the bootloader options work. If i select recover or factory reset or whichever it just vibrates and goe back to fastboot screen.
I have a stock rom that it loads up but fails all but one file when updating. Didn't think bootloader needed to be unlocked to use a stock rom so don't know why that is happening. Phone did boot up once the other day after constantly trying to load up a diff rom but only stayed on for 15-20 min before it locked up and restarted back in fastboot screen. Wtf is wrong with this thing? I should mention it did this randomly from the start.
