# 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
