How to downgrade iOS 9 to iOS 8.4.1?

by the company Apple On September 16, the updated OS was presented. There were some delays with the update operating system, but after 2-3 days the number of people wanting to update the OS will drop and everything can be done much faster. The first people have already appeared who want to roll back the system after updating to the previously installed iOS 8.4.1. Let's talk about how this can be done.

There are no significant reasons for such operations: the updated OS works smoothly, the San Francisco font looks amazingly beautiful, and “notes” in which you can draw have been the dream of many for many years. If the desire to roll back still remains, some determination will be required. Apple has allocated very little time for these manipulations, during which you need to have time to roll back the system.

You will need a Lightning cable to downgrade the OS or a previous version for iPad 2/3/4 or iPhone 4s. You must enable iTunes on your computer. download IPSW file(source of the old operating system), which can be downloaded by following the link: http://osxdaily.com/2015/08/13/ios-8-4-1-update-ipsw-download, you will need to select the version of the mobile device. Next you need to follow the instructions:

1. On your mobile device you need to go to: Settings-iCloud menu and then disable the “Find my iPhone” option.
2. You will need to turn off your mobile device; to do this, you need to hold the lock button for a long time. Then launch iTunes on your personal computer.
3. We connect the iOS mobile device via a cable to the computer, and you need to immediately hold down the home and lock buttons at the same time. You need to hold for at least 10 seconds. Next, you need to release the lock button and continue to hold the home button. You need to hold it until a warning window appears in iTunes that the iOS device has appeared in Recovery Mode.
4. In iTunes, you need to select the model of your gadget and click on the “Restore iPhone” button, while holding down the Shift button on Windows or the OPTION button on Mac.
5. You need to select the IPSW file that was downloaded earlier.
6. Wait for the process to complete, then the device should start. Ready.

Is the decision to stay on iOS 8.4.1 justified? The updated OS works great, no visible glitches, problems or lags have been detected yet. The only reason justifying old version operating system are applications. It may take a long time to adapt applications to the new OS. In general, there is no need to rush to switch to iOS 9.

It is possible to roll back to previous version operating system. Apple traditionally leaves this option for a short time after the release of each new OS. A day after the update was released, the company is still issuing certificates for iOS 8.4.1.
