iOS 10 Beta Downgrade to iOS 9.3.2

It’s always the same process, every year and every major release of iOS brings about the temptation of installing the new beta on your iPhone. And then you notice that you actually need a fully working device with adequate battery life in practice, because it is your production phone and you run on it. Beta firmware is meant to be installed on development devices or test devices and can cause unexpected trouble. So here’s a guide on how to downgrade iOS 10 to iOS 9.3.2 if you are experiencing issues.

Important downgrade hints & preparation

You can only downgrade iOS 10 to iOS 9.3.2, as older versions of iOS are not being signed anymore by Apple.

The data you have added since the upgrade to or installation of iOS 10 on your iPhone will be lost. This is due to the iOS 10 backup not being compatible with older versions of iOS. There are ways around this restriction but, they are not fully reliable and we have not tested them yet. We recommend using iOS 9 backups on iOS 9 to make things easier.

Either way, please create a full backup using iTunes while you are still on the iOS 10 beta, just to make sure that you have something to go back to in case something along the way goes horribly wrong, or your older backups prove to be corrupted.

Downloading the iOS 9.3.2 firmware

Download the correct firmware for your device by checking the following website for your model:

Select your device from the dropdown menu, then select the topmost iOS version with a green background, which means that it is the latest firmware that is currently signed, in this case iOS 9.3.2, then click Download.

Put your iPhone in DFU mode

Next, we will be putting your iPhone into DFU mode so the firmware can be safely restored. Connect your iPhone to your PC or Mac running iTunes, then put it into DFU mode using the button combination. If you need help with this step, check out our separate guide on the topic. Read More…

Proceed with downgrading iOS 10

Select your device from the icon bar in iTunes to get to the overview. Then press and hold the Alt/Option key on your Mac, or the Shift key on Windows, then click Restore iPhone… to select your freshly downloaded IPSW firmware file. Then follow the on-screen instructions. The entire process should take only about 10 minutes, depending on how recent your iPhone is, among other factors.

Restore your iOS backup

You can now restore a recent backup that was created on iOS 9, either via iCloud or via iTunes, depending on your preferred backup method. Read More..

Again, restoring an iOS 10 backup on iOS 9 devices is currently not a supported method.
