Hi ,I have an iphone 3g, jailbroken running on 3.1.3 firmware. Last night, after trying to open cydia, it crashed. So i googled up "how to fix cydia crashing etc..." so this guy said to go into the root from ifile (/, private, var, lib, apt, lists) and the guy said to delete everysingle file there except for folders, and so i did. and i only had one folder left. I restarted my iphone, and it was turning on. First the apple logo, then the apple logo with a spinning wheel. This spinning wheel would normally freeze, but today it kept on going, and then the iphone shut down. it stays on the spinning icon, for around 1min then shuts down. Have entered DFU mode but no use... Unfortunately, i dont have a computer backup, and without turning the iphone on, i cant use alternative software to back it up... HELP!!!
