Power failure during firmware update

… now USB is not detected on PC.

How can I resolve this?

Any details on unit type, upgrade method, what version were you going from to, is there any activity on any of the other interfaces such as UART CTS line toggling on power up?



During a firmware upgrade from 3.2 to 4.04 using odin, there was a power failure in my building

Still no details on unit type, method, etc.
