How to Restore a Jailbroken iPhone
Jailbreaking your iPhone allows you customize your iPhone by downloading applications not available through Apple's App Store, and also allows you to use your iPhone on any Global Systems for Mobile Communications (GSM) cellular network worldwide. While not illegal, jailbreaking your iPhone does void the terms and conditions of Apple's warranty. At times, you may want to restore a jailbroken iPhone. Restoring the iPhone will reset your device to its factory settings, removing the jailbreak.
Things You'll Need
- iPhone data cable
- Computer with iTunes
Attach the iPhone data cable to the bottom of your iPhone and connect the other end of the data cable to an available USB port on your computer.
Open the iTunes program on your computer.
Click your "iPhone," located under the "Devices" subsection of the iTunes window.
Click the "Restore" button.
Confirm that you want to restore your iPhone to its factory settings.
Wait while iTunes syncs with your iPhone and restores the device to its original factory settings. The restore will automatically remove the jailbreak. When the process is complete, iTunes will prompt you to remove your device from the data cable.
Tips & Warnings
- You should back up your iPhone using iTunes prior to restoring your device.
