Apple recently released IOS 15 beta. According to past experience, newly released IOS systems often have many bugs. I remind you not to rush to upgrade recently, but many small partners still can’t help but upgrade first. After upgrading, it was found that the beta version was unstable, which completely affected the current use. But don’t worry, you can try the downgrade system.
IOS 15 downgrade notes
IOS is a closed system, that is, whether we upgrade or downgrade, we need Apple’s official verification. At present, the downgradable channel provided by apple is only the official version of IOS 14.6.
After degradation, all data on the device will be deleted, so we need to back up the data on the device in advance. We can use Apple’s official tool icloud / iTunes for backup. After the downgrade, we can restore the previous backup data.
Don’t use the computer and equipment during the downgrade. It’s best to wait until the downgrade is over, otherwise the downgrade may be interrupted and the equipment will turn brick.
Remember the screen lock password, apple account and password of the device before brushing, which will be used after brushing.
How to downgrade IOS 15 system?
Step 1: Download fengke system repair software on our computer. After downloading, double-click to start and select ‘standard mode’.
Step 2: connect the iPhone to the computer with the data cable, and the software will prompt us to put the device in recovery mode or DFU mode.
Step 3: after we successfully set the iPhone to recovery mode or DFU mode, the software recognizes the device information and matches it to the firmware package. We can select a firmware package lower than IOS 15 beta and click ‘download’.
Step 4: after downloading the firmware package, we just need to click ‘fix now’ to start demoting the IOS system.
After the whole process, the phone will restart. After restarting, check whether the system has been downgraded successfully.
