Downgrade 32-bit Devices to Any iOS Version With SHSH

[TGB]

Jailbreaking is available for all 32-bits devices after Phoenix and H3lix released. And jailbreaking could help to restore to some unsigned iOS versions. Here’s the completed tutorial about downgrading to any iOS version with shsh. You can save shsh on 3uTools restore to the current iOS version on your device.



Thanks developer tihmstar and his futurerestore tool.

Compatibility

iPhone 4s, iPhone 5, iPhone 5c, iPad 2, iPad 3, iPad 4, iPad mini, iPod touch 5G

Available Firmware to Restore

With corresponding SHSH, you can restore to iOS 5 - iOS 9. (Except iOS 9 on iPhone 5/5c)

Requirements

Futurerestore (downgrading tool)
3uTools
iTunes
A 32-bit device
A jailbreak on the starting firmware.
The IPSW file for the destination firmware, you can download from 3uTools | iOS jailbreak & flash tool

On 3uTools server, I’ve only saved SHSH of iOS 9.3.5 and iOS 6.1.3 for our testing iDevice, iPhone 4s, but I saved the SHSH Of iOS 8.3 on another server. So I will take downgrading to iOS 8.3 for example.

Operation

1. Verify SHSH

(1) Check and download SHSH of iOS 8.3 you saved on 3uTools. (If you saved SHSH on another server, you can just downloaded.)



(2) This assistant tool is developed by a Chinese developer, there’s only Chinese version temporarily.
Download and unzip Futurerestore, and launch wndGui.exe, you will see as follow.



(3) Click the fifth button, "验证SHSH". After you select the iOS firmware and SHSH, click “确定” to begin verifying.



(4) The following picture means that the SHSH is legit, it will automatically generate the .plist file of SHSH. You can put the .plist file and iOS 8.3 firmware in the new folder.




2. Enter KDFU mode
