# 32bit-OTA-Downgrader
### Downgrade/restore 32-bit iOS devices to iOS 8.4.1 or iOS 6.1.3
# iOS-OTA-Downgrader
### (formerly 32bit-OTA-Downgrader)
### Downgrade/restore iOS devices to signed OTA firmwares
- **Please see "Other notes" below to serve as answers for FAQs**
## Supported devices:
- **iOS 8.4.1**: All A5, A5X, A6, and A6X devices are supported **except iPad2,2 (iPad 2 GSM), iPhone5,3 and 5,4 (iPhone 5C)**
- **iOS 10.3.3**: (Linux only) All A7 devices are supported **except iPad4,6 iPad4,7 iPad4,8 iPad4,9**
- **iOS 8.4.1**: All A5, A5X, A6, and A6X devices are supported **except iPad2,2 (iPad 2 GSM) iPhone5,3 and 5,4 (iPhone 5C)**
- **iOS 6.1.3**: Only iPhone 4S and iPad 2 devices are supported **except iPad2,2 (iPad 2 GSM) and iPad2,4 (iPad 2 Rev A)**
## Prerequisites:
- A supported 32-bit iOS device **jailbroken** on any version
- **iOS [8.4.1](https://ipsw.me/8.4.1) or [6.1.3](https://ipsw.me/6.1.3) IPSW** for your device (the script can also download it for you)
- 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. [Download](https://github.com/LukeZGD/32bit-OTA-Downgrader/archive/master.zip) or `git clone` this repo
2. Plug in your iOS device in normal mode
3. Open Terminal, cd to the directory where the script is located (example: `cd /home/user/32bit-OTA-Downgrader`)
4. Run `chmod +x restore.sh`
5. Run `./restore.sh`
6. Select option to be used
7. Follow instructions
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
