How to Go to Normal Mode With an iPhone
Tweaking your iPhone's settings without prior knowledge of an application's functions easily results in your iPhone remaining in DFU mode, also known as recovery mode. In order to exit recovery mode and return to normal mode, the device requires being restored in iTunes, which reverts the phone's settings to its original factory configuration settings. Although this causes your iPhone to re-lock to the default cellular network, the iPhone can be unlocked at a later date with a third-party program.
Things You'll Need
- ITunes 8.0 or later
- IPhone dock connector cable
Insert the dock connector cable into the iPhone and into the USB port on your computer.
Run iTunes. Click the iPhone's tab in the side menu of iTunes, and click "Restore."
Click "Restore" to revert the iPhone to its original settings.
Leave the iPhone connected to the computer until the device restore process is complete and the iPhone Setup Assistant window appears on your computer.
