After iOS 15.4 came out for a while, many people agreed with the new features and specifications. especially about the face scanning system, even when wearing a mask But what I found is that there is a problem with this operating system. The question is, how would you like to downgrade to the previous version? Today we have a method together. By the way, downgrade iOS 15.4 to iOS 15.3.1, is there any way to see?
The first step is to download the Software iOS 15.3.1 here.
Make sure that There will be a symbol in the device that is green in order to use it.
To turn off Find My iPhone, go to Settings > iCloud > select Find My iPhone and enter your passcode.
Then plug it into your computer and open iTunes > select the symbol of iPhone Then it will update immediately. However, the computer that can do this must be MacOS only. However, when you press update, you must press and hold the alt/option key and install File iOS 15.3.1.
Select the Delete and Restore feature (erase and restore) and then press Restore, then the device will restart itself.
Therefore, the update in the Downgrade version must be carefully looked at. because the upgrade time will not be able to back again However, we will have to wait and see how long the downgrade can last.
