I've made a severe mistake. I restarted my 2G Touch in order to install some stuff from Cydia. Then I was trying to boot it with iRecovery, but unfortunately one of the 3 files was missing and I needed to extract it from a firmware, however, I couldn't find it so I downloaded it again. But I was in a hurry and I could not finish the reboot process and I think I've left the Touch for a day in DFU mode. Now, it's completely bricked, I cannot even hear any sign of the USB activity, so I think it has completely run out of battery. I can't put it into DFU now either, and the cable is not charging the battery. What do you suggest me to do? Please help!
