GH13 body bricked?

[mr bill]

A disaster - i accidentally nudged the lens release button on my GH13 body whilst applying a hack patch. Firmware upgrade froze, turned off camera, took out battery, body now lifeless. Can the body be brought back from the dead if I get a dealer service or is now useless?

thanks

Maybe via Panasonic service (afterwards unhackable) or a JTAG cable but the later one is very complex.
