Apple seeded the first version of iOS 10 beta few days back which includes several cool features and improvements. You can downgrade from the iOS 10 beta to iOS 9 fairly easily, but you need to take one special step during the restore process or your downgrade to iOS 9 will fail. Using this guide you can downgrade from iOS 10 to iOS 9.3.2 from the developer iOS 10 beta and it should work later this year to downgrade from the public iOS 10 beta to iOS9.
Downgrade iOS 10 beta to iOS 9.3.2
Step 1. Before doing anything else, back up your iPhone, iPad, or iPod touch (if you already have a pre-iOS 10 beta backup, you can restore from that too, either way be sure you have a backup)
Step 2. Download the iOS 9.3.2 firmware file for your device from here.
Step 3. Now just place your iPhone in DFU Mode.
Step 4. Connect the device to your computer and Launch iTunes and select the iOS device from the top right corner, to the left of the iTunes Store button.
Step 5. Choose the device within iTunes and go to the Summary page, then do the following:
- For Mac OS X: OPTION + click the “Restore iPhone” button
- For Windows: SHIFT + click the “Restore” button
Step 6. Navigate to and choose the iOS 9.3.2 firmware .ipsw file that was downloaded earlier, and choose to Update. iTunes will now verify the software and install it on your device. It should take around 10 minutes.
Step 7. After it is successfully restored to iOS 9.3.2, 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, iPad or iPod touch should now be successfully downgraded from iOS 10 beta to iOS 9.3.2.
