not charging or connecting after iOS upgrade to 6

Hi,

I have upgraded my old 3GS iOS to 6.1, after the upgrade it rebooted correctly but stayed on iTunes logo and stopped charging good, is not recognized anymore by iTunes and even by the computer.

I tried DFU mode and reset mode with no success.

So there is no way to recover it with iTunes.

It recognizes the SIM card but will not connect to the operator, signal stays on 1 bar.

thank You
