# 32bit-OTA-Downgrader
### Downgrade 32-bit iOS devices to iOS 8.4.1 or iOS 6.1.3 (see supported devices below first!)
### Downgrade 32-bit iOS devices to iOS 8.4.1 or iOS 6.1.3 (see supported devices below)
- **Please see "Other notes" below to serve as answers for FAQs**
## Supported devices (iOS 8.4.1 downgrade):
- All A5, A5X, A6, and A6X devices **except iPhone5,3 and 5,4 (iPhone 5C)** are supported
## Supported devices (iOS 6.1.3 downgrade):
- Only iPhone 4S and iPad 2 devices except iPad2,4 (iPad 2 Rev A) are supported
## Prerequisites:
- A supported 32-bit device **jailbroken** on any iOS version
- 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 **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/))
- **macOS** (tested on 10.13 and 10.14 only) should also work, but I won't be able to provide support when the script breaks
- 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/openssh.html); The computer and device must be on the same network for SSH to work
- 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/)
## How to use:
@ -20,22 +28,14 @@
6. Select option to be used (8.4.1/6.1.3 downgrade)
7. Follow instructions
## Supported devices (iOS 8.4.1 downgrade):
- All A5, A5X, A6, and A6X devices **except iPhone5,3 and 5,4 (iPhone 5C)** are supported
## Supported devices (iOS 6.1.3 downgrade):
- Only iPhone 4S and iPad 2 devices except iPad2,4 (iPad 2 Rev A) are supported
## Other notes:
- **You do NOT need blobs to use this**, the script will get them for you
- This script will also restore your device to the latest baseband (N/A to devices with no baseband)
- This script will restore your device with the latest baseband (N/A to devices with no baseband)
- This script has a workaround for the activation error on iOS 10 devices
- This script uses the futurerestore method for downgrading, NOT the Odysseus method nor modifying SystemVersion.plist
- This script will use an unmodified IPSW to restore
- This script only uses iBSS patches from bundles for entering pwnDFU mode, NOT for creating a custom IPSW
- This script can also be used to enter kDFU mode for all supported devices
- This script uses futurerestore "Odysseus method" for downgrading (different from OdysseusOTA/2, which are deprecated)
- This script uses an unmodified IPSW to restore and does NOT create a custom IPSW
- 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 when provided with SHSH blobs
- This script should also work on virtual machines, but I won't provide support on them
