If you accidentally updated your iOS Device to iOS 9.1 but would like to downgrade to iOS 9.0.2, then the good news is that you can do it for a short period of time. So, you can downgrade from iOS 9.1 to iOS 9.0.2 until Apple keep signing the iOS 9.0.2 Firmware File.
Important Points to Read before Downgrade
- You can only downgrade to iOS 9.0.2
- You will be able to downgrade to iOS 9.0.2 as long as Apple continues signing iOS 9.0.2 Firmware File
- You should take a backup using iTunes or iCloud before starting the downgrade process
Note: Before starting the downgrade process, you should check if Apple is still signing the firmware file. To do this, check this website. If there is a green row with a tick means that Apple is still signing the firmware file, so you can downgrade from iOS 9.1 to iOS 9.0.2.

Note: To make this method work, you have to download iOS 9.0.2 IPSW File for your iOS Device from the Download Section.

Step 4: Your file browser will open and you have to select the iOS 9.0.2 IPSW File you had downloaded earlier.
Step 6: iTunes will give you information about the update and you have to agree with them by clicking the Next button.
iTunes should now begin installing iOS 9.0.2 on your iOS Device and should take about 10 minutes.
After the installation is finished, you should see the Hello Screen and your device is ready to get restored from the backup you did on the beginning of this tutorial.
That’s it. You have successfully Downgraded from iOS 9.1 to iOS 9.0.2.
The second method to Downgrade from iOS 9.1 to iOS 9.0.2 is much faster than the previous one.
Step 1: First, Turn off Find My iPhone from the Settings app – iCloud – Find My iPhone.
Note: If you have set a 6 digit passcode, then you have to change it to a 4 digit passcode because after downgrading back to iOS 9.0.2, you won’t be able to unlock your device.
Step 2: Connect your iOS 9.1 Device to your computer.
Step 3: Select your iOS Device on iTunes from the top left corner.
Step 4: Hold the Alt/Option key on the Mac or Shift Key in Windows on your keyboard and click on the Check for Update Option from the Summary Tab.
Step 5: Select the iOS 9.0.2 IPSW File you had downloaded earlier. If you haven’t downloaded it, then get it from the Download Section.
Step 6: After selecting the iOS 9.0.2 File, iTunes will inform you that will update your device to iOS 9.0.2 and will verify the firmware with Apple. You have to click Update Option to confirm it.
iTunes should now begin installing and downgrading to iOS 9.0.2.
After the downgrade is finished, you should see “Slide to Upgrade” Screen. Slide your screen, enter your passcode and wait for the downgrade to complete.
That’s it. You have now successfully downgraded to iOS 9.0.2.
Note: Please note that Apple can stop signing iOS 9.0.2 Firmware file at any moment. Always check before downloading the iPSW File if Apple is still signing it. You won’t be able to downgrade to iOS 9.0.2 if Apple stops signing it.
If you get the error message “This device isn’t eligible for the requested build” then it is because Apple has stopped signing the iOS 9.0.2 iPSW file or you’ve downloaded the wrong iPSW file for your iOS Device.
