Apple released iOS 9.3.2 few days back with a number of bug fixes and improvements.
If you upgraded your iPhone, iPad or iPod touch to iOS 9.3.2 accidentally or are facing an annoying issue after upgrading to iOS 9.3.2, then you could try downgrading back iOS 9.3.1 as Apple is still signing the iOS 9.3.1 firmware file.
Important points
- You will be able to downgrade back only to iOS 9.3.1.
- You will be able to downgrade as long as Apple continues to sign iOS 9.3.1 firmware file.
- It is important to take a backup of your iOS device to iCloud or using iTunes so you can restore from the backup if something goes wrong.
- Apple doesn’t recommend downgrading so; please proceed at your risk.

How to downgrade from iOS 9.3.2 to iOS 9.3.1
If Apple is still signing iOS 9.3.1, please follow these simple instructions to downgrade iOS 9.3.2:
Method 1:
This method is recommended, but it is more time-consuming as it involves restoring data from backup. It is also important to note that you will be able only to restore from the last iOS 9.3.1 compatible backup, and will lose the data since upgrading to iOS 9.3.2. With Method 2, you won’t lose the data, but it is a riskier method.
- Download the iOS 9.3.1 firmware file for your device. The iOS 9.3.1 firmware file for iPhone 6s Plus is iPhone8,2_9.3.1_13E238_Restore.ipsw. Accordingly, download the appropriate firmware file from our iOS firmware file download page for your iPhone, iPad or iPod touch.
Note: If you’re downloading the firmware file using Safari then ensure that auto unzip feature is disabled or use Chrome or Firefox. Alternatively, renaming the .zip file as .ipsw file should also work.
- You now need to put your device in DFU mode (if you want to find out what it means check this post for more details):
- Plug your device into your computer.
- Turn off the device by holding the Sleep/Wake or Power button and swiping it off.
- Hold the power button for 3 seconds.
- Begin holding the Home button without releasing the Sleep/Power button for 10 seconds.
- Release the power button and continue holding the home button until you get a popup from iTunes that it has detected that your device is in Recovery mode.
- Click on the Ok button.
- Hold the Alt/Option key on the Mac or Shift key in Windows on your keyboard and click on the Restore iPhone… (iPad/iPod touch…) button. Note: If you directly click on the Restore iPhone button without holding the Alt/Option key on the Mac or Shift key in Windows will result in restoring your device back to iOS 9.3.1.
- Select the iOS 9.3.1 IPSW file you had downloaded earlier.
- Then click on the Restore and Update button to continue.
- In the next screen, it will give you information about the iOS 9.3.1 update. Click on the Next button, followed by the Agree button to continue.
- iTunes will now verify the software and install it on your device. It should take around 10 minutes.
- After it is successfully restored to iOS 9.3.1, you should see the white ‘Helo’ screen. Follow the on-screen instructions to set up your device, and restore your device from the backup to restore your personal data.
That’s it. Your iPhone or iPad should now be successfully downgraded to iOS 9.3.1.
Method 2:
This method is much faster, and a method we’ve used successfully several times, but it would be important to highlight that it is not the recommended method. It is important that you take a backup of your device on your computer using iTunes or to iCloud.
- Turn off Find my iPhone via the Settings app (Settings > iCloud > Find my iPhone).
- Download the iOS 9.3.1 firmware file for your device. The iOS 9.3.1 firmware file for iPhone 6s Plus is iPhone8,2_9.3.1_13E238_Restore.ipsw. Accordingly, download the appropriate firmware file from our iOS firmware file download page for your iPhone, iPad or iPod touch.
Note: If you’re downloading the firmware file using Safari then ensure that auto unzip feature is disabled or use Chrome or Firefox. Alternatively, renaming the .zip file as .ipsw file should also work.
- Connect your iPhone, iPad or iPod touch to your computer.
- Launch iTunes and select the iOS device from the top left corner.
- Hold the Alt/Option key on the Mac or Shift Key in Windows on your keyboard and click on the Check for Update option, instead of restoring.
- Select the iOS 9.3.1 ipsw file you had downloaded earlier.
- iTunes will inform that it will update your iOS device to iOS 9.3.1 and will verify the update with Apple.
- Click Update.
- iTunes should now downgrade your iOS device to iOS 9.3.1.
- After downgrading, the iOS device will restart. You should then see “Slide to upgrade”. Enter the passcode, and then wait for the downgrade process to complete. You may be prompted to activate your device.
That’s it. Your device should now be successfully downgraded to iOS 9.3.1.
Please note that Apple can stop signing iOS 9.3.1 firmware files any moment. Once Apple stops signing the firmware file, you won’t be able to downgrade from iOS 9.3.2 to 9.3.1. So downgrade as soon as possible.
If you get the error message “This device isn’t eligible for the requested build” then it is probably because Apple has stopped signing the iOS 9.3.1 firmware file or you’ve downloaded the wrong firmware file for your device.
