Guide notes

  • (iPhone only) This method only works up to the iPhone 6s. The method to do this changed with the iPhone 7.
  • iCloud warning: Devices running iOS 7 or newer will have an iCloud activation lock. If you restore a device with unknown credentials, you will no longer be able to use the device. Furthermore, devices with an unofficial iCloud unlock will no longer work.
  • With iOS 8 and up, the device data is encrypted. If you need your data, you must guess the password.
  • WARNING: ALL DATA ON THE DEVICE WILL BE ERASED! IF POSSIBLE, GUESS THE PASSWORD.

If you purchased a used iDevice or forgot the password on your current device, this guide will show you how to restore the device so you can use it again. If you did not forget the password but are having problems that prevent a normal recovery, this method can also be used for this purpose.

步骤 1 Plug the device into a computer  ¶ 

Clearing a unknown password while keeping the data intact is beyond the scope of this guide. Plug your device into your computer. Use the cable that matches the era your device is from (30-pin or Lightning).
