What should I do to restore the factory setting white screen after Apple's mobile phone jailbreaks?

To refresh the phone, it needs to be clear that the jailbroken iOS device cannot restore the factory settings through Restore in the settings, and the result of this operation is "white apple"! \x0d\ can be restored by brushing into the system through third-party assistant software such as itunes or AISI Assistant. The following is an example of using AISI Assistant to brush into the iphone system: \x0d\ Step 1, download and install AISI Assistant on the computer and connect the iPhone to the computer. After the connection is successful, AISI Assistant will display the machine information; \x0d\ Step 2, click Firmware Download in the main interface, and AISI Assistant will automatically select available system firmware to download according to its own needs; \x0d\ Step 3: Back up your phone book, photos, documents, etc. Once you brush it, you can't take it back! Make sure that Find My iphone is closed, that is, there is no AppleID lock; \x0d\ Step 4, click AISI Toolbox-Select Firmware and select the downloaded system firmware; \x0d\ Step 5, click "Brush Machine Now", enter DFU mode according to the pop-up prompt, and then wait for the brush machine to finish.
