I have an iPhone 4 that has a broken power button. There is no warranty because I bought it from my friend.
It has never been a problem because I had AssistiveTouch, until now.
I went to use the iPhone one day and it was stuck in a boot loop.
I have never attempted to jailbreak it or install 3rd party software onto it. When I connect it to iTunes it says that I need to respond on the iPhone before I can restore or sync it. I can't respond because it's in a boot loop and I can't enter DFU mode because the power button is broken.
Is there a way to put the phone in to DFU mode when it's power button is broken?
UPDATE: After I made this post, I plugged my iPhone into a Samsung wall charger and it booted properly. I used it all day, until it died. Once I got home, I plugged it into the charger, and now it's stuck on the boot loop again. When the iPhone booted normally, iTunes allowed me to put files on it, etc. I have already tried RecBoot, and iTunes won't let me sync.

If your iPhone is stuck in recovery mode, DO THIS: (ON Screen USB pointing to a CD with a Music Note).
Make sure your iTunes is up to data, if not re-download itunes.
after re-installing ITUNES, plug your iphone via USB into your computer. ITUNES will automatically pick it up and a pop up box will probally say that your IPHONE is in recovery mode would you like to restore?
Click the restore tab. Note - If ITUNES if out of date, this will not work. Note - Do not do this over WIFI Note - Do not interrupt the restore Note - If you did not make a previous back up, your IPHONE will restore back to the factroy settings.
All this happened to me, fortunately I made a back up. I hope this helps.
