Using the Arduino pwned state, you can tether-boot any custom firmware. Tools like ra1nstorm (Linux) or synackuk’s a5_loader allow you to install a persistent (semi-tethered) jailbreak that survives reboots. The Arduino acts as a "pwn-dongle."
Here is where the magic happens. The standard Checkm8 script ( checkm8.py ) won't work on an Arduino. You need the firmware. arduino+a5+checkm8+exclusive
Having an Arduino A5 Checkm8 Exclusive setup unlocks several powerful, exclusive capabilities. Using the Arduino pwned state, you can tether-boot
The vulnerability lies in the DFU (Device Firmware Update) mode code within the iPhone's bootrom. The SBROM allows a computer to send firmware images via USB. The exploit works by: Using the Arduino pwned state
