## 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 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/))
- **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
- 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)
- 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

## Other notes:
- **You do NOT need blobs to use this**, the script will get them for you
- 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
- 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 uses an unmodified IPSW to restore and does NOT create a custom IPSW
- 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 when provided with SHSH blobs
- This script should also work on virtual machines, but I won't provide support on them
- This script can also be used to uturerestore to other iOS versions with provided SHSH blobs
- This script can also work on virtual machines, but I won't provide support for them
