ipwndfu

ipwndfu is an open-source jailbreaking tool designed for various iOS devices, leveraging the permanent unpatchable bootrom exploit known as checkm8. Primarily aimed at researchers, it allows for operations such as dumping SecureROM, decrypting keybags, and enabling JTAG on affected devices. Notable features include support for multiple SoC architectures, the ability to jailbreak and downgrade the iPhone 3GS without SHSH blobs, and an underlying capability to manage hex data during pwned DFU Mode.
