Don't do that. T2 with 1.0.03.09110 is a very valuable device.
Once you upgrade to 1.0.05.11130 it becomes worthless.
1.0.03.09110 is the firmware everybody dreams about when attempting to buy T2.
Once upgraded to a newer firmware, it is not possible to downgrade back, unless you already jailbreaked your T2 before upgrading.
I hope you somehow failed to upgrade. Not sure about the usb problem, though.
