Is there a way to update/reset the USB via a pc as I can't update/reset the firmware for it on the ps3 as it doesn't recognise it.
Forget about it
As i suggested yet, i would repeat my best advice: Put some electric tape on the second half, at the end of your dongle. I suppose your asshole friend touching the dongle received a tiny electric shock. Dongle is dead for electrical failure, surely. Send it back to your reseller, if Lighttake they will send you a new one. Dunno about other resellers. Most could ignore you.
Yeah, it's me Dj Barth "One TrueBlue to rule them all, One Browser to find them,
One TB CFW to bring them all and in the Internal HDD bind them
