Hi,
During firmware update my dash cam died (someone asked me to update A139 firmware and boot loader), is there anyway to make it alive again?
Dash cam is not turning on and there is no sign of life.
I had to use the reset as unit didnt like 2.5 and wouldn't power up after attempting to update firmware. Battery pack and PC wouldn't power it but when I put it back into car it powered on and the update installed.

OP flashed the A139 bootloader into the A129 Pro, which will allow flashing of A139 firmware.
If you still have your device you can try to flash back the A129 Pro boot loader, then flash back A129 Pro firmware.
You may need to rename the A129 Pro Bootloader to a A139 bootloader for it to be accepted.
