Hi!

I think your only chance is to hope the failure is caused by damaged software not by the hardware. Let's try a software update:

1. remove the battery
2. wait some seconds
3. reconnect the battery
4. turn your ipronto on an press "mute" and "channel +". Pressing those keys at the beginning of the bootprocess calls the Menu titled "manual configuration"

If the menu doesn't apear i don't know what to do:

do next steps if the menu apears
5. go to "restore" and activate "flag for update"
5. "done"
6. resume.

If all works fine the ipronto will now download the latest software.
