How to: Exit DFU MODE WITHOUT Restoring iPhone, iPad, iPod touch, STEP BY STEP!. Disclaimer: Do this at your own risk, I am not responsible for any damage to your iPhone although I highly doubt anything will happen.
In this video, I will teach you how to get your iPhone out of DFU MODE if redsn0w crashed or perhaps your friend thought it was a funny joke, without restoring. This is for DFU MODE not recovery mode..Although iTunes may say recovery mode, this is the recovery mode I am talking about:
1) If you try to power on your iPhone and it wont because you entered DFU MODE with redsn0w and nothing shows up on the screen then this is for you.
-if you have an itunes symbol with a USB cable on your iPhone screen then this is NOT for you.
Alright, the steps are simple.
1) Charge up your iPhone for a while. (I have heard that being in DFU MODE will not allow you to charge the iphone but it won't hurt to try..leave it charged for 4 hours if this doesn't work.
2) Unplug the iPhone from the computer and hold BOTH the home and power button until the apple logo is shown, once thats done, just wait for your iPhone to restart.
