I told you in the morning how to install iOS 9.1 beta 1 on iPhone, iPad and iPod Touch, and now I will also tell you how to downgrade iOS 9.1 beta 1 to iOS 8.4.1 on your terminals if you need such a thing.
Considering that Apple no longer signs SHSHs for iOS 8.4, you can only downgrade to iOS 8.4.1 at the moment, so you should not expect to be able to restore to another version of the operating system because it's impossible.
Downgrade iOS 9.1 beta 1 to iOS 8.4.1
Before starting the process of downgrade iOS 9.1 beta 1 to iOS 8.4.1 I must warn you that it is advisable to make a backup of your data using iTunes and not iCloud, because if you have an old backup of iOS 8.4.1 in iCloud, it will definitely be usable.
In the same way, I recommend that you make sure that you remember your Apple ID password if you have Find my iPhone active, but also that you have the activation card, if the terminal is blocked in a foreign network.
- Download iOS 8.4.1.
- Connect your iPhone, iPad and iPod Touch to your computer and open iTunes.
- Put your device into DFU Mode by following these steps: Press the Home and Lock buttons simultaneously for 10 seconds, release the Lock button, and hold only the Home button until iTunes recognizes the device, even if the screen remains blank.
- Press the button Check for iTunes Update and the program will install the version chosen by you in your terminals.
- If option 4 does not work, use the button Restore and the procedure should work.
After completing the procedure you will have iOS 8.4.1 installed again on your iPhone, iPad and iPod Touch and of course you will be able to install again iOS 8.4.1 as long as Apple will sign SHSHs for him.
