- Please make sure that the “Find My iPhone” or “Activation lock is not enabled” on the iPhone iPhone or iPad device, or that you know the ID lock account number and password, otherwise, the device may not be activated after flashing.
- After the device is upgraded to the beta version of iOS 16.3 (20D47), it will no longer be able to downgrade to the “Apple has turned off verification” firmware version, even if the SHSH was backed up with 3uTools before, it cannot be downgraded.
- After the device is upgraded to the iOS 16.3 (20D47) version, if you want to downgrade to another “Apple has not turned off verification” version, it is not recommended to check “Keep user data for flashing machine“. 3uTools classifies and backs up the data and performs a new flash, and then classifies and restores the data after success.
