Help! My DFU is messed up and I am locked out!
Hello! I recently started a project to fix an iPhone 3GS for a friend. I repaired it just fine, but then to boot it up and find that there is a passcode on it! Yaaaaay..... :( My friend does not know the passcode, and my iTunes is not synced with the device, so my only option was to use DFU mode, one problem though, when I try to enter DFU mode, the phone just straight up refuses! It will boot up, and stay at the apple logo for a couple of seconds after vibrating (beacuse it is plugged in to my PC). I cannot try to guess the password as the phone just says "Phone Disabled, Connect to iTunes". If anyone knows how to fix this, please help. Thanks!
