Please see the "Other notes" section below to serve as answers/solutions for FAQs and issues

Supported devices:

iOS 10.3.3 - A7 devices:
- iPhone 5S
- iPad Air
- iPad mini 2 except iPad4,6
- iPad mini 3 is NOT supported
iOS 8.4.1 - 32-bit devices:

- iPad 2
- iPad 3
- iPad mini 1
- iPod 5th gen
- iPhone 5C is NOT Supported
iOS 6.1.3:

A supported device in any iOS version:
- A 32-bit iOS device (jailbreak needed for kloader, checkm8 A5 or ipwndfu can also be used in DFU advanced menu)
- An A7 device (jailbreak not needed)
An IPSW for the version you want to downgrade to (the script can also download it for you)
A macOS or a 64-bit Linux install/live USB
- See supported Linux distros below
- A live USB can be easily created with tools like balenaEtcher or Rufus)
All 32-bit users must install OpenSSH
- A6/A6X iOS 10 users must install Dropbear (deb) as well
For 32-bit users using Pangu, install the latest Pangu 7.1.x Untether (deb) or latest Pangu 8.0-8.1.x Untether (deb)

Download or git clone this repo
Open Terminal and cd to the directory where the script is located (example: cd /home/user/iOS-OTA-Downgrader)
Run chmod +x restore.sh

You do NOT need blobs to use this, the script will get them for you
If the restore process does not work for you, try switching USB ports and/or cables
This script will verify the IPSW SHA1sum before restoring
For users having issues related to missing libraries or tools, re-install dependencies with ./restore.sh Install
For A7 devices:
- Do not use USB-C to lightning cables as this can prevent a successful restore
- checkm8 ipwndfu is unfortunately pretty unreliable, you may have to try multiple times (for Linux users I recommend trying in a live USB)
- If the script can't find your device in pwnREC mode or gets stuck, you may have to start over
For 32-bit devices:
- This script does not modify the IPSW
- 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 can also be used to just enter kDFU mode for all supported devices
- This script can also restore your device to other iOS versions with provided SHSH blobs
- This script can work on virtual machines, but I won't provide support for them
