## 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 **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/))
|
|
- 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)

|
|
|
|
## How to use:
|

|
|
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`)

|
## Other notes:
|
|
- **You do NOT need blobs to use this**, the script will get them for you
|
|
- 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 does not modify the IPSW and will verify it with SHA1sum before restoring
|
|
- 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 also work on virtual machines, but I won't provide support for them
|
