How to Run Checkm8 Exploit (iPwnDFU Mode) on iOS 8 – 13.2.2

The release of the checkm8 BootROM exploit by axi0mX has paved the way for the development of a working jailbreak tool for iOS 13 – iOS 13.2.2. The checkm8 BootROM exploit is extremely powerful as it is a hardware-based exploit and cannot be patched by Apple by merely a software update. Apart from using the exploit to the development of a jailbreak tool for iOS 13, it can be utilized for a number of things like dual-booting two different iOS versions on the same device, flashing a custom firmware for jailbreaking, and more.
