I haven't seen anything like this before. Okay, so I boot like normal today - put it in DFU, use 1clickboot or the manual commands that we know have always worked. Now, there's a problem. Recently, whenever I try to boot, it goes to the silver apple logo for 10-15 seconds, right? Then once the Apple logo comes up, like normal, it stays that way for 15 seconds then shuts off instead of booting up. By shuts off I mean goes into tethered off mode where THE USE DEVICE CAN NOT BE RECOGNIZED, you all know what I mean. I'm no noob, I know how to do this right and have been doing it a while since jailbreak. Why is it doing this suddenly? What do I do? And restoring is not a valid answer. Before it started doing this is it was fully charged too, so that's not the problem.
