For users who have upgraded to the beta version of iOS 17, if they feel that it is not so stable during the experience process, such as problems such as app incompatibility, battery life decline, and functions that cannot be enabled normally, you can refer to this tutorial if you want to perform a downgrade operation.
Notes before downgrading:
1. Due to the limitations of the iOS system, the data cannot be directly retained during the downgrade operation, otherwise there will be problems during the flashing process, resulting in the failure of the device to work normally. Therefore, it is necessary to back up the data in advance before downgrading.
2. When downgrading, you cannot downgrade back to the iOS version that Apple has officially closed verification (for example, the versions that can be flashed now include iOS 16.5 and iOS 16.5.1).
3. Please make sure you know the Apple ID and password bound to the device, or log out of the Apple ID and turn off the "Find My iPhone" function on the device in advance.
