Pretty much anyone can get iOS 10 beta running on a compatible device, even without a developer account. The problem is, we’re still at the first developer build and bugs are aplenty. Nevertheless, if you tried the latest update and had a subpar experience, you can simply downgrade from iOS 10 beta to iOS 9.
Apple officially warns us it’s not possible to downgrade from iOS 10 to an earlier version when in fact it is, and it’s really not that difficult.
Before you proceed, here’s what you need to know. You can only downgrade back to the latest official version of iOS, which is currently iOS 9.3.2. Before you downgrade your iPhone, iPad or iPod touch from iOS 10 beta to iOS 9, you will need to backup your data.
The process will wipe your device and allow you to restore the data from a backup. Also, the backup needs to be compatible with iOS 9 and to ensure of this we recommend you perform a manual backup (the quickest way to do it is from Settings -> iCloud -> Backup).
Downgrade from iOS 10 beta to iOS 9
Assuming you already went through the steps mentioned above, you will need to download the iOS 9.3.2 firmware for your specific device. You can download it from this page once you select your device model and the iOS version. Take a moment to ensure you download the correct firmware for your device. Otherwise, you will get an error during the downgrade process.
Note: We recommend you download the firmware via Firefox or Chrome. However, if you want to use Safari you will need to disable the auto unzip function or rename the .zip file as a .ipsw file.
To continue, you will need to put your iPhone, iPad or iPod touch into Device Firmware Upgrade (DFU) mode. To do this, plug the device into your computer and turn it off.
Then, press and hold the Power button for 3 seconds. Without releasing it, also press and hold the Home button or about 10 seconds. Release the Power button but keep holding the Home button. You will soon see a popup letting you know that iTunes detected your device in Recovery mode.
Click OK to dismiss the popup and while holding the Option key on a Mac (or the Shift key on a Windows computer) click on ‘Restore iPhone/iPad/iPod touch’ option. Holding the Option/Shift key will allow you to manually select a firmware file, so you can choose the one you just downloaded.
Note: If you just click on the Restore option without holding the Option/Shift key, iTunes will attempt to download the firmware for you, which often results in an error.
After you select the firmware file, click on the Restore and Update option.
On the following screens click on Next and Agree to allow te downgrade process to start. When the downgrade process is complete, you simply need to follow the instructions to configure your device and restore its data from a previous backup.
As you can see, it’s not difficult to downgrade from iOS 10 beta to iOS 9, but you do need to be careful, especially when you select the firmware. Let us know if you went through the process and if you experienced any problems.
