I used AI, and I mention it in the post. I'm also an engineer at IBM, and I know a bit about operating systems and embedded systems, which helps me understand and decipher parts of the iPod. I also have a small workshop where I was able to repair an iPod that had been broken for a few years. The community is truly amazing, and it supported me in subsequent research such as freemyipod and https://github.com/devos50/qemu-ios
