# 32bit-OTA-Downgrader
- This script can be used to downgrade almost any supported 32-bit device to **iOS 8.4.1**
- iPhone 4S and some iPad 2 devices also have the option to downgrade to **iOS 6.1.3**
- This script will also restore your device to the latest baseband (N/A to devices with no baseband)
- This can also be used to enter pwnDFU mode for all supported devices
- **For iPhone 5C, 8.4.1 OTA DOWNGRADING IS NOT SUPPORTED!** Supports entering pwnDFU mode ONLY
- **You do NOT need blobs to use this**, the script will get them for you

### Prerequisites:
- **A jailbroken A5/A5X/A6/A6X iOS device on any iOS version** (Latest jailbreaks: [Phoenix](https://phoenixpwn.com/) for 9.3.5/9.3.6, [h3lix](https://h3lix.tihmstar.net/) for 10.3.3/10.3.4) 
- **iOS [8.4.1](https://ipsw.me/8.4.1) or [6.1.3](https://ipsw.me/6.1.3) IPSW for your device**
- A **macOS** or **Linux install/live USB** (Tested on [Xenial (16.04)](http://cdimage.ubuntu.com/lubuntu/releases/16.04/release/), [Bionic (18.04)](http://cdimage.ubuntu.com/lubuntu/releases/18.04/release/), and [Arch-based](https://www.archlinux.org/) distros) (a live USB can be easily created with tools like [balenaEtcher](https://www.balena.io/etcher/) or [Rufus](https://rufus.ie/)) (macOS tested on 10.13 and 10.14)
- iOS 7 Pangu users: install the [latest Pangu 7.1.x Untether (deb)](http://apt.saurik.com/debs/io.pangu.axe7_0.3_iphoneos-arm.deb)
- iOS 8 Pangu users: install the [latest Pangu 8.0-8.1.x Untether (deb)](http://apt.saurik.com/debs/io.pangu.xuanyuansword8_0.5_iphoneos-arm.deb)
- The computer and device must be on the same network (for SSH)

### How to use:
1. iOS 9 and below: Install [OpenSSH](https://cydia.saurik.com/openssh.html), iOS 10: Install [MTerminal](http://cydia.saurik.com/package/com.officialscheduler.mterminal/)
2. [Download](https://github.com/LukeZGD/32bit-OTA-Downgrader/archive/master.zip) or `git clone` this repo
3. Open Terminal, cd to the directory where the scripts are located (example: `cd /home/user/32bit-OTA-Downgrader`)
4. Run `chmod +x restore.sh`
5. Run `./restore.sh`
6. Select option to be used (8.4.1/6.1.3 downgrade or just enter pwnDFU mode)
7. Follow instructions

### Some other notes:
- This script uses the futurerestore method for downgrading, NOT the Odysseus method nor modifying SystemVersion.plist
- This script will use a vanilla/unmodified IPSW to restore
- This script only uses iBSS patches from bundles for entering pwnDFU mode, NOT for creating a custom IPSW
- For VirtualBox users, add a New USB Filter in the VM settings for the iOS device to autoconnect to the VM
- For VMWare users, enable Autoconnect USB Devices
