well dropping it didnt help, but it sounds like the temperature change has caused some condensation which in turn has corrupted the rom, or at the very least stopped it from booting correctly. if you didnt wait for it to equilize to room temperature it will be like any electronic device operating below its temperature threshhold, that combined with condensation makes one funky acting device. ive seen this before even with my devices i just shut them off and let them warm up.

that said. it seems you have relocked it and had a botched rom flash because there was not sufficient time to let the device warm up and lose the moisture it has gathered in the form of condensation from the rapid temperature change. which means................ its boned... take it back he has a brick. and how they replace it.
