|
|
|
|
## Prerequisites:
|
|
- A supported device:
|
|
- A 32-bit iOS device (any version, **jailbreak needed**)
|
|
- An A7 device (any version, jailbreak not needed)
|
|
- An IPSW for the version you want to downgrade to (the script can also download it for you)
|
|
- A **macOS** or a **64-bit Linux install/live USB** (see distros tested on below) (a live USB can be easily created with tools like [balenaEtcher](https://www.balena.io/etcher/) or [Rufus](https://rufus.ie/))
|
|
- 32-bit users only:
|
|
- iOS 7/8 Pangu users: Install the [latest Pangu 7.1.x Untether (deb)](http://apt.saurik.com/debs/io.pangu.axe7_0.3_iphoneos-arm.deb) or [latest Pangu 8.0-8.1.x Untether (deb)](http://apt.saurik.com/debs/io.pangu.xuanyuansword8_0.5_iphoneos-arm.deb)
|
|
- iOS 9 and below users: Install [OpenSSH](https://cydia.saurik.com/package/openssh/); The computer and iOS device must be on the same network for SSH to work
|
|
- iOS 10 users: Install [MTerminal](http://cydia.saurik.com/package/com.officialscheduler.mterminal/)
|
|
1. [Download](https://github.com/LukeZGD/iOS-OTA-Downgrader/archive/master.zip) or `git clone` this repo
|
|
2. Open Terminal, cd to the directory where the script is located (example: `cd /home/user/iOS-OTA-Downgrader`)
|
|
3. Run `chmod +x restore.sh`
|
|
|
|
## How to use:
|
|
1. Plug in your iOS device in:
|
|
- Normal mode (32-bit)
|
|
- Recovery or DFU mode (A7)
|
|
2. Run `./restore.sh`
|
|
3. Select option to be used
|
|
4. Follow instructions
|
|
|
|
## Other notes:
|
|
- **You do NOT need blobs to use this**, the script will get them for you
|
|
- This script will verify the IPSW with SHA1sum before restoring
|
|
- 32-bit only:
|
|
- This script does not modify the IPSW
|
|
- To devices with baseband, this script will restore your device with the latest baseband
|
|
- This script has a workaround for the activation error on devices downgrading from iOS 10
|
|
- This script uses futurerestore "Odysseus method" for downgrading (different from OdysseusOTA/2, which are deprecated)
|
|
- This script only uses iBSS patches for entering kDFU mode
|
|
- This script can also be used to just enter kDFU mode for all supported devices
|
|
- This script can also be used to futurerestore to other iOS versions with provided SHSH blobs
|
|
- This script can work on virtual machines, but I won't provide support for them
|
|
|
|
