If you’re on an iOS 11 beta build and you’re struggling with bugs and other issues, or if you simply want to open your device to a future jailbreak for iOS 10.3.1 and/or iOS 10.3.2, this is the time to downgrade. Apple is still signing those two versions of iOS, as well as the second beta of iOS 10.3.3.
The downgrade process is fairly straightforward, and the process has been outlined below:
- First, update your iTunes on your Mac or PC to the latest version. Download the latest iTunes version here.
- Next, you need the IPSW file for iOS 10.3.2 or iOS 10.3.1, depending on what you want to downgrade to. We recommend iOS 10.3.1, but also recommend saving your SHSH2 blobs for iOS 10.3.2 for the future.
- Get the IPSW file for your device type here. Make sure you choose the iOS version you want to downgrade to.
- Now, move to your iOS device, then go to Home Screen >> Settings >> iCloud >> Find My iPhone, and toggle it to Off. If prompted for your Apple ID, type that in and then toggle it to Off.
- Next, connect your device to your PC and open iTunes. Wait until your device appears on the left side and click on it.
- Once this is done, hold down the alt/option key on Macs, or the Shift key on PCs. this will force iTunes to give you an option to select the IPSW file you just downloaded to your machine.
- Select the right IPSW file and let iTunes do its job of restoring your device to the lower iOS version you chose. And you’re done.
- Rinse and repeat for the other version in case you have another device.
- For both iOS versions, save your blobs using the TSS Saver tool from 1Conan.
Why Downgrade or iOS 10.3.2 or iOS 10.3.1?
For one, if your device is on iOS 11 beta and Apple stops signing iOS 10.3.2 and iOS 10.3.1, you can never downgrade to those versions on that device unless you save your blobs for both those versions while Apple is still signing them.
The second reason is very strong if you’re a jailbreak enthusiast of any level – from novice to expert. We don’t hold much hope for an iOS 10.3.2 jailbreak, but there are already un-patched vulnerabilities in iOS 10.3.1 that can be used to write an exploit and compile a jailbreak from. One that we know of is Adam Donenfeld’s exploit for iOS 10.3.1 that he’ll be subsequently releasing the source code for.
Those two reasons should give you enough incentive to downgrade now while you have the option. Either iOS 10.3.1 or iOS 10.3.2 is fine, as long as you save blobs for both versions.
