iOS users will no longer have to worry about voiding their hardware warranty or forfeiting Apple's in-warranty technical support or facing unwanted issues after jailbreaking their device. It is possible to regain the warranty status or remove existing jailbreak tweaks on your iDevice by simply restoring it to factory settings.
IBTimes UK brings you a comprehensive step-by-step guide to restore your jailbroken iPhone, iPad or iPod Touch to factory settings in just a few simple steps. Users should ensure that they meet all the pre-requisites given below, before proceeding with the actual restoration steps.
- Ensure the latest version of iTunes is installed on your device.
- Back up important data on the device via iTunes to prevent data loss, as the restoration process will erase all data on the device.
- Turn off Find my iPhone feature as follows: go to Settings > iCloud and tap the Find My iPhone On/Off toggle to disable it. This will also disable Activation Lock.
- NOTE: Restoring the device from backup via iCloud could be a time-consuming process, as it depends on the amount of data stored (backed up) on the device as well as the internet connection speed.
How to Restore Your Jailbroken iOS Device to Factory Settings
- Connect the iOS device to computer.
- Wait until your iOS device is recognised by iTunes and then choose your iPhone, iPad or iPod Touch in the device listing in iTunes (it should appear next to iTunes Store button in the top right corner).
- Now tap the Restore button under Summary tab.
- iTunes throws a confirmation prompt to restore your iOS device to factory settings. Once again, hit the Restore button to continue.
- Wait until your iDevice is restored to factory settings and then the device should automatically restart.
- A Hello message with a "Slide to set up" slider will now appear on screen. Follow onscreen instructions to setup the device either as new device or restore it from earlier backup files.
The cellular service on the device will be activated once the restoration process completes.
