How to Downgrade iOS 11 Beta to iOS 10

Did you install iOS 11 beta onto your iPhone or iPad, but now want to downgrade to iOS 10 and revert to a more stable system software version? You’re likely not alone.

Fortunately just like it’s easy to install iOS 11 beta right now (even without a developer account), it’s also easy to downgrade iOS 11 back down and revert to iOS 10.

In this tutorial we will demonstrate downgrading iOS 11 beta back to the most recent stable iOS 10.3.3 build.

Downgrading iOS 11 beta is pretty easy. You will need the following: a device running iOS 11, a signed version of iOS 10 IPSW, a modern release of iTunes on a Mac or PC, a USB cable, and an internet connection. That’s about it.

We will show you the the simplest method to downgrade iOS 11 beta back to iOS 10. Downgrading does not require using recovery mode or DFU mode unless the iPhone or iPad is not able to boot or is bricked by a failed software update.

How to Downgrade iOS 11 to iOS 10.3.3

You should have a recent backup available of your iOS device to avoid potential data loss. Note that iOS 11 backups are not able to be restored to iOS 10, so if your most recent backup is from iOS 11 then you will not be able to restore that to a downgraded iPhone or iPad.

1. Download the iOS 10.3.3 IPSW file for your iPhone or iPad and put the .ipsw file somewhere easily accessible – you can find other IPSW here but remember you must choose a version being actively signed which is typically the most recent stable release



2. Launch iTunes on a Mac or Windows PC



3. Connect the iPhone, iPad, or iPod touch to downgrade to the computer with a USB cable



4. Choose the device within iTunes, then under the summary section in iTunes do the following to start the downgrade process:
   • Mac: OPTION + click the “Update” button
   • Windows: SHIFT + click the “Update” button

   

5. Choose the iOS 10 IPSW file you downloaded earlier and update / restore to that version
6. Let the downgrade process complete, the iPhone or iPad screen will turn black as the process begins and it will reboot several times

Downgrading iOS 11 back down to iOS 10.x.x may take a while, depending on the size of your iPhone or iPad and how much stuff you have on it.

Note that if the downgrade fails for whatever reason, you can also choose to alt/shift click on the “Restore” button but in doing so the device will be restored and setup as new.

If you have the iOS 11 public beta installed, and you wish to downgrade back to iOS 10, you will need to downgrade to iOS 10.3.3.

Only iOS 10.3.3 is being signed by Apple, thus that is the version you must downgrade to.

Downgrade from iOS 11 beta failed? Use Recovery or DFU Downgrade

Finally if the downgrade process bricks or the iPhone or iPad gets stuck on an Apple logo or something similar, that is when you would want to go a step further and put the device into DFU mode (you can read how to put iPhone 7 into DFU and how to put other iPhone and iPad models into DFU mode too) or recovery mode and then attempt to downgrade and restore the device again – this is pretty rare and should not be necessary for most simple uncomplicated downgrade situations.
