Is it possible to format the storage on an 8821 using the power on keypad sequence and then install firmware via USB?

What are you trying to accomplish?

You can do a factory reset using the power on  keypad sequence. video  link attached below. installing the firmware using USB, asper my knowledge it not possible. you need to use local TFTP method  or try registering with Callmanager and upgrade it.

Trying to recover an 8821 that fails to boot. Have tried factory reset key sequence and boot alternate firmware key sequence without success. It may be a hardware fault, but just wondered if there was a way to wipe and flash firmware onto it in case it was a corrupt firmware issue. Thanks.
