I've got a friend's HTC One M8 that's stuck in HBOOT. I can't flash a new recovery, I've tried both TWRP and CWM. Either time I get an error message "FAILED (remote: image update error)"
I'm at the end of my thread here with things I can try to fix it. I've searched almost all topics to no avail.
Here's the getvar dump:

Device says *** UNLOCKED *** on screen, doesn't say TAMPERED (not sure what this is).
Anything fastboot commands usually result in a failed message but the device is recognized if I type "fastboot devices".
Here's a sample when trying to use Squabbi's toolkit:
target reported max download size of 1830727680 bytes
sending 'recovery' (24576 KB)...
OKAY [ 1.607s]
FAILED (remote: image update error)
finished. total time: 1.678s
I've tried using an ATT RUU, various recovery files, etc. The phone boots straight into HBOOT. Any other commands apart from fastboot on the device result in a quick flash of another screen and returns to the fastboot USB screen.
What can I do to get this device back up and running? For some reason I just can't get the recovery file to flash so I can move forward already. Am I missing something? I just got the device from a friend. He mentioned he was watching YT when all of a sudden the device went into this boot loop.
Thanks in advance!
