iOS-downgrade-tethered

SORRY THIS PROGRAM MAYBE NOT USABLE YET

This program maybe NOT USABLE. The problem is that kloader reports failed to get kernel_baseel base or just stops working when doing the final step. The reason is unknown. I am not able to find a fix currently. Please use the tutorial (link provided in description) instead.
If someone has a fix please send me a Pull Request.

Description

Downgrade method from here

A simple downgrade script which can downgrade 32-bit devices to ANY version.

Currently supported device is iPad3,1. Supported iOS is iOS 7-9.1. More will add in the future.

IMPORTANT: This tool does not use any BootROM exploits.
Do not power off your device if you have downgraded your device using this tool. It will BRICK your device.
The only way to power off is: jailbreak your device, then run ./kloader pwnediBSS in your shell.

If your device is supported by checkm8 exploitation tool (such as ipwndfu), maybe you can still boot even you have powered off your device.
