Factory Resetting an iOS Device

Factory Resetting an IOS Device

Note: This process should only be followed if you are prepared to update to the latest iOS version. Apple forces this behavior and prevents users from selecting a specific version. With this, please ensure that the version you are upgrading to has a supported jailbreak that can be used, as this is a major requirement in Lab Workstation device provisioning.

Requirements: 

  • iOS Device with USB cable

  • Host machine running Windows/Mac OSX with ITunes installed

  • Internet Connection (to download the iOS Update)

  • A SIM card (does NOT have to be an activated one)**

  • SIM card will be required for iPhone (5s and older) and iPad devices that have cellular capability. This is an activation process imposed by Apple and just needs to detect the presence of a SIM card, not an active cellular connection.

Also before beginning, you will want to check the “Find my iPhone” settings on the device itself.  If this feature is enabled, and the device is restored, the device will be locked, and can only be unlocked by using the Apple ID/Password that was used to setup the “Find my iPhone” feature.

You can check this in Settings -> iCloud.  If there is an Apple ID tied to the device itself, this option is usually enabled by default.  Look to see if the “Find My iPhone” feature is enabled.  We recommend just deleting the account from the device completely before restoring, just to be on the safe side.  You can do this by clicking “Delete Account” located at the bottom of the iCloud settings.

Steps:

Plug the device into the host machine using the USB cable. This should launch iTunes automatically. If not, you will need to manually start up iTunes.

iTunes will detect the device. If it starts to sync, you can cancel that action, as we are going to reset the device to a stock state. If this is the first time connecting this iPhone to iTunes, you may need to step through a couple setup screens to continue on to the restore process.

Once you get to the main device screen, you will see two options, “Update” and “Restore iPhone”.  Do not click on the update option as this could cause issues with the device itself.  Use the “Restore iPhone” option to initiate the reset process.

A confirmation menu will appear.  Select “Restore and Update” to proceed.  Note: This WILL erase any and all data (including apps, data, keychain items, certs, history, etc..) from the device.  This is the point of no return.

Once clicked, the iOS download will be initiated.  This may take a few minutes to download based on the speed of the Internet connection.

Once downloaded, the phone will reboot and the device will start the update process.  When the device has been restored, you will be walked-though a few setup screens that collect basic information (country, WiFi network, etc..).

A connection to Apple is required to ensure that the device has not been locked/blacklisted.  This can be accomplished by either connecting the device to WiFi, or connecting to ITunes.

The last step of this process is the SIM card check.  If your device has cellular capability (iPhone 5s or older), you will be prompted with an insert SIM screen:

Insert a SIM card and click “Try Again”.  Once complete, it will progress past this screen and the setup will continue.

Complete the rest of the setup until you arrive at the home screen. This step is now complete.
