Note, this guide is made especially with IDA Pro, its freeware version does not contain ARM support so either get IDA by your own means or base this guide off of another disassembler like Hopper.
You can find these in the CLI folder of this my repo "Dual-Boot-Stuff."
The other programs are not needed but aid in research and adding a few more elements to the dualboot, or anything that resides in a similar process.
