Hello, welcome to the UltFone Channel. Have you tried the latest iOS 16 beta yet?
Although there are many new features that are good,
it is in the testing stage and is not stable. In today's video,
I will show you how to downgrade iOS 16 beta to iOS15.
It must be noted that downgrading will result in data loss,
so we need to make a backup before we start. It is recommended that you use iTunes to backup
your iPhone data to the computer. Backup path select this computer,
Then click backup now. Now I will show you two downgrade iOS 16 to
iOS 15 methods. So let’s get started.
Method 1: Use iTunes So open your browser and go to IPSW.me.
Select our idevice model, Then we can see the latest iOS 15 IPSW file,
Click on it. Then go ahead and download it to your computer.
Well done, the download is finished. Let’s open iTunes.
Then connect your iPhone to the computer. Because the iPhone is in the iOS 16 beta,
it cannot be read normally, don't worry, we directly follow the prompts
to the recovery page. Press and hold shift on the keyboard while
clicking restore. Then find the iOS 15 file you just downloaded
and open it. Have you followed me to back up your phone
data to your computer just now? If you have backed it up, you can click restore to procceed,
otherwise your data will not be restored. Well done, now let’s go ahead and set it
up. Now you can see your iPhone lands iOS 15 version.
If you want to restore the previous data, remember to go to iTunes to restore,
the end of the video will show how to restore it.
Now I will show you next more easy method. Method 2: Use UltFone iOS System Repair [Three
clicks] Open UltFone iOS System Repair after you back
up your iPhone data. Then connect your iPhone to the computer.
Now go back to UltFone iOS System Repair and click start option.
Then we need to click deep repair to proceed. Click to download,
UltFone iOS System Repair will download the latest iOS15 firmware for you.
Now click start to deep repair to proceed. Well done, it’s finished.
Let’s set it up. Now you can see we are in iOS 15 version.
Finally I will show you how to restore your data from your iTunes backup.
Before we start, note that this backup is not compatible with
the iOS 15 we have now. So for this to work, we are going to make
some changes to this backup. Hold the Win and R key to open the run window.
Type in %appdata%, and then click OK. Now we are going to Apple computer, mobile
sync, If you don’t see the Backup folder here,
type in %userprofile% instead, Then go to Apple, MobileSync, open the Backup
folder. Judged by last modified time,
this should be the backup we created just before.
Let’s get inside the folder. Scroll down to bottom, and find the info.plist
file, Open it up with the notepad.
Press control and F to launch the search tool. And search for the word product.
Not too far down we’ll find the product version.
Below it we can see iOS 16.0. What we are going to do is change it to iOS
15.0. then go ahead and save this file.
now we can get back to iTunes and start to restore.
Click on restore backup, and select the one we just modified.
And now it says the restore is in process, Just like that.
