Downgrade iOS 11.3 Beta to iOS 11.2.x – Here’s How [Update]
Here's how you can downgrade iOS 11.3 Beta firmware to iOS 11.2.5, iOS 11.2.2, iOS 11.2.1 or iOS 11.2 on iPhone or iPad.
Downgrade iOS 11.3 Beta Back to the Official, Public Release Channel on iPhone or iPad - Here's How
If you are a developer or public beta tester then you can go ahead and install iOS 11.3 right now. Of course, it's beta software therefore things might prove to be a little unstable in certain corners. If that's something which is bothering you then you can go ahead and downgrade straight back to the publicly available version of the iOS 11.x firmware.
But before we go ahead and do that, it's important to know that downgrading the firmware will erase everything off your device. This in turn means that you should backup everything to either iCloud or iTunes, the choice is yours as long as everything is nice and secure.
Last but not the least, it's important to know that you can downgrade to only a certain set of firmware at this point in time. The latest release is iOS 11.2.5, but other than that, Apple is currently signing the following firmware releases: iOS 11.2.2, iOS 11.2.1 and iOS 11.2. Given that iOS 11.2.5 is a major bug fix release, I would recommend sticking to that. Also, once Apple stops signing the last three firmware releases mentioned above, you cannot downgrade anymore. So there's another reasons for you to stick to iOS 11.2.5.
Download the Firmware to Which You Want to Downgrade to
First and foremost, download the firmware to which you wish to downgrade to.
Downgrade iOS 11.3 Beta - Tutorial
- Connect your iPhone or iPad to your PC or Mac using a Lightning cable.
- Launch iTunes. If you haven't installed it already then you can download it from: apple.com/itunes
- Once your device is detected by iTunes, it'll appear in the upper top left hand corner. Click the little icon that looks like a little iPhone.
- Now click on the 'Restore iPhone' button while holding down the left Shift key (Windows) or the left Option key (Mac).
- Select the IPSW firmware file you downloaded, that's it.
iTunes will verify the firmware file with Apple then restore your device. If the firmware if currently not being signed then iTunes will throw you an error. But if everything goes well, you'll boot straight into the iOS welcome screen.
IMPORTANT UPDATE: Apple has stopped signing iOS 11.2, iOS 11.2.1 and iOS 11.2.2 making downgrade impossible to those firmware versions. Only downgrade to iOS 11.2.5 is possible at this point.
