IOS 16 Return 15.7 Method Introduction

1. First, you need to prepare a computer, download and install Apple's official iTunes on the computer. After the installation is completed, open iTunes and connect the phone to the computer. iTunes will display the phone information, then backup the data in the current phone through iTunes, and click [Backup Now]. You can complete the backup operation on iOS16.

2. After the data is backed up, you need to find and modify a [Info. plist] file. The address of this file in the Mac OS system is [Resource Library/Application support/Mobilesync/Backup]. You can find this file in the subfolder of this document. For the Windows system, its address is [C:/Users/username/AppData/Roaming/AppleComputer/MobileSync/Backup], where the user is the name set by the computer, which can be changed according to the specific situation. After finding this file, you can open it by right clicking Notepad. After opening it, press Command+F for the Mac OS system and Ctrl+F for the Windows system to search for the version number of the system you just backed up, i.e. 16.0, etc, Change the version number to the version to be restored, such as 15.7. After saving, you can complete the data backup before the downgrade.

3. There is another step to be operated before the machine is flushed, that is, turn off the [Find My iPhone] in the original iPhone, so that the password lock and activation lock do not need to be entered later. After the operation, the mobile phone is still connected to the computer, and the Aisi Assistant is downloaded and installed. The official version of iOS 15.7 system firmware is downloaded on the smart phone cleaning page. After the download is completed, you can directly select a regular fast phone cleaning without clicking on the reserved data and wait for the completion of the machine cleaning.

4. After the machine is flushed, use iTunes again to restore the data just backed up, and you can downgrade the iPhone from ios16 to ios15.7.

It is not easy to return ios15.7 from ios16. The overall process is still complicated and requires patience and slow operation. If the above operations cannot be returned, the user can restore the phone directly, but the current data of the phone will be lost.
