## What it is
An all-in-one shell-based tool for restoring, downgrading, jailbreaking, and saving SHSH blobs on legacy iOS devices vulnerable to bootrom exploits like checkm8. It supports 32-bit devices and some 64-bit (A7-A11) devices with features like SSH ramdisk booting, sideloading, and NVRAM clearing.

## Use cases
- downgrade iPhone 4 to an unsigned iOS version
- save SHSH blobs for old iPad
- jailbreak a 32-bit iPhone on iOS 9
- restore iPod touch to signed OTA iOS 6.1.3
- boot SSH ramdisk on legacy iPhone
- install TrollStore on iOS 14 device
- activate old iPhone without SIM card

## When to choose
- you own a legacy 32-bit or A7-A11 iOS device and want to downgrade or restore it
- you need to save SHSH blobs for old devices
- you want to jailbreak old iOS versions
- you need hacktivation or NVRAM clearing on old iPhones

## When to avoid
- your device is a modern one that received iOS 16+ (limited functionality only)
- you want a graphical user interface
- you need to jailbreak current iOS versions on recent devices
