How to downgrade iOS 15.7 after the official version is updated

The iOS system installed in Apple's mobile phone is constantly updated. Generally speaking, the large version will be updated once or twice a year, but the small version of the system will be updated every month. Recently, the iOS 16 system has attracted more attention. However, Apple has also officially pushed the official version of iOS 15.7. Many fans want to know how to downgrade the official version of iOS 15.7 after it is updated? The following small compilation will bring you specific solutions.

How can I downgrade iOS 15.7 after the official version is updated? Introduction to the downgrade method after the upgrade of iOS 15.7 official version

1. After upgrading the official version of iOS, you cannot downgrade back to the official version of iOS that has been closed for verification.

2. Due to the limitation of the iOS system, during the downgrade operation, you cannot check "Save user data for refreshing" (you cannot directly save the data in the device for refreshing), otherwise problems may occur. All data in the device will be cleared after the downgrade.

3. After the high version is downgraded to the low version, the data of the high version cannot be fully recovered to the low version system directly. You can use the Aisi Assistant classified backup function to back up data (application data cannot be backed up), and restore to the device after the downgrade is successful.

4. Please make sure that the activation lock is not enabled on the mobile device, or you know the ID lock account and password, otherwise you may not be able to activate and use the device after the device is flushed.

It is relatively simple to downgrade iOS 15.7 after the official version is updated. However, it may have some impact on the mobile phone by using the mobile phone flushing method. If you can accept the current system of the mobile phone, you should not downgrade it for the time being.
