How to Downgrade iPhone/iPad with TinyUmbrella
There are two kinds of Apple users that want to downgrade iOS on their iPhone/iPad. For jailbreakers, they often downgrade iOS 10 to iOS 9, iOS 9 to iOS 8, iOS 9 to iOS 7 so that they can jailbreak. For regular users who have installed latest iOS 11 and don't like it, they just want to roll back to iOS 11.1 from iOS 11.1.1.
If you belong to the first kind, you might have heard of TinyUmbrella and wonder if it is a workable iOS downgrade tool that can help you. And if you are the latter, please jump to Part 3 for a foolproof tool to downgrade iOS 11.1.1 to iOS 11.1/11.0.x without iTunes.
As we all know, Apple encourages users to update iOS to the newest version and doesn't allow us to downgrade to older iOS versions. It often discontinues signing a particular iOS firmware after the release of a new version, and thus stops users to downgrade.
TinyUmbrella is an iOS downgrade tool that can save SHSH blobs (Apple's signature protocol for iOS restores and updates), and use the blobs to create a pre-signed IPSW firmware file that can downgrade iPhone/iPad to an older iOS version even if Apple has stopped signing the version.
However, since Apple has patched the loophole that allowed users to use SHSH blobs in iOS 7 or later, TinyUmbrella's iOS downgrade method doesn't work anymore. Now you can only use SHSH blobs to downgrade to iOS 6.x on iPhone 3GS, iPod Touch 4G, iPhone 4, and iPad 2. To downgrade iOS 11, iOS 10, iOS 9, iOS 8 on other iOS devices, you can download other iOS downgrade tool like Prometheus, iDeviceReRestore to downgrade with or without SHSH2 Blobs.
Yet you can still use TinyUmbrella to save SHSH blobs, which could be useful if some hackers discover a new way to downgrade back to older iOS versions in the future. Moreover, TinyUmbrella can also get iPhone/iPad/iPod Touch out of recovery mode without wiping data.
To downgrade iOS 11, iOS 10, iOS 9, you probably want to save SHSH blobs with TinyUmbrella so that you can still have SHSH blobs if there is a workable downgrade method in the future.
Step 1 Launch TinyUmbrella and connect your iPhone/iPad to the computer with the lightning cable.
Step 2 Once your iPhone/iPad is detected, all the SHSH blobs available in the device will automatically be downloaded and saved on your computer.
Note: All the blobs are saved in one single file. You can find it at ~/.tu/.shsh on your computer. TinyUmbrella only downloads SHSH blobs for the firmware that is still being signed by Apple. For example, if your iPhone is now on iOS 10.3.2 and Apple has stopped signing the version, TinyUmbrella will not download blobs for iOS 11.1 / iOS 11.0.X.
If you have installed iOS 11 beta and it causes troubles on your iPhone/iPad, you could downgrade iOS 11.1.1 to iOS 11.1 to solve the problem. Here is a solution to downgrade iOS without iTunes or TinyUmbrella: using FonePaw iOS System Recovery.
