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 (UNTESTED)
• This can also be used to enter pwnDFU mode for all supported devices

Some other notes:

• You do NOT need blobs to use this, the script will save them for you
• For iPhone 5C, 8.4.1 OTA DOWNGRADING IS NOT SUPPORTED! Supports entering pwnDFU mode ONLY
• 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

• iOS 8.4.1 or 6.1.3 IPSW for your device
• A Linux install or live USB (Tested on Lubuntu 16.04, 18.04, Manjaro, and Arch Linux) (a live USB can be easily created with tools like balenaEtcher or Rufus)
• OpenSSH installed on iOS device
• MTerminal installed on iOS device (10.x users only)
• iOS 7 Pangu users should install the latest Pangu 7.1.x Untether
