FIRMWARE UPDATE FAILURE

Roofel

My GX-785-UR16 failed to update and has now bricked itself. It turns on for about 5 seconds and then shuts off and repeats until I unplug it from the psu. Is there anything I can do to fix it without sending it in.

try a CMOS reset.
unplug the power cable, open the left side of your case (front looking), take off the CMOS battery (it's the silver button battery under the GPU), press the power button twice and wait 5 minutes before putting everything back.

try to boot.

if it doesn't boot, you can only call Acer support service.
