UltData(iPhone Data Recovery) is a data recovery software for iPhone, iPad and iPod. It can recover lost, deleted contents like contacts, photos, text messages, call history, and more from iOS devices after entering DFU mode on your device. After it finished the task, how can we get out of DFU mode?
Here you can find an easy tutorial about how to get out of DFU on your iPhone 5/4S/4/3GS, iPad 4/mini/3/2, or iPod Touch 5/4.
Just close the software after you have finished recovering lost files from your device. And your device will get out of DFU automatically and turn back to normal mode.
To exit iPhone DFU Mode, hold down the "Power" and "Home" buttons, and then release these buttons once the Apple logo appears on the screen. Wait for the iPhone to boot up. Repeat the above process if it does not.
