How to Get out of DFU Mode without Restoring Your iPhone

iPhone DFU(Device Firmware Upgrade) mode is a state you can put your iPhone into where it can interface with iTunes but does not load the iOS. In DFU mode, you will see just white background on the screen while recovery mode shows the "Connect to iTunes" sign.

Manually get out of DFU mode

1. Start iTunes and connect iPhone to your computer; 2. Hold down both HOME and Sleep/Wake buttons for 10 seconds; 3. Hit the Power button and wait until your iPhone restart.
