I have done RGH on my Xbox 360 slim and flash the drive on a Zephyr. I made my own probe by following tutorial. I tried to activate Dev mode on my console, I use my school email and still didn't get to activate it. Not sure why.
That's not what I meant.
You used finished products and followed tutorials - but you probably don't know what exactly you did there and why you had to do it to achieve a certain goal.
If you realy want to start attacking devices you need to understand the way they work and what exactly they are doing.
Try to reimplement them in your own way from scratch and start with the easier hacks.
Only so you can learn what it realy takes to hack these things.
You will not find points on the XBO drives where it basically says "solder your wires here to dump the drive" - trust me
After all that happened to the 360, this won't be the way to do it
