So, I did some searching and was unable to find a solution to this problem, sorry if it's a repeat. So earlier today I was using SMSbite on my iPhone 4 when the phone suddenly crashed. Since that point, the phone has not been able too boot up fully. It will get past the apple logo and will sit and hang on the lock screen for about 5-15 seconds before it crashes and reboots itself. Here's the problem: it just keeps doing this. I have tried to put the phone in DFU mode, but the phone seems to crash before I can fully reset the phone. I have held the sleep/home button down on it's own for over a minute, the phone shut down but then rebooted. I have pressed the sleep/home button and then pressed the home button to try and place it into DFU mode. The same thing happens, the phone crashes before it can take the command and simply stays in the loop. The phone is completely dead now, I plugged it in to the wall to give it a charge but it did the same thing and I was unable to stop the loop that it was in. Any advice on how to make it so I can get iTunes to read my phone so I can restore it?
