Hi, so I have an iPhone 3G jailbroken at 4.2.1. It was working fine until my STUPID brother decided to STUPIDLY press "Restore all Content and Settings" on the iPhone. Now it's stuck in the death loop.
WORST OF ALL, MY POWER BUTTON DOESN'T WORK.
Is there anyway I could get it into DFU or Recovery Mode without the Power Button?
Nope! You have to use the power button and home button so unless you can access cydia there's probably not much you can do. You may be able to restore it using iTunes just by plugging the iPhone in and going to restore/update but apart from the above I can't think of much else.
