I want to say first of all, I have not got a Xbox one. I have not looked into the hardware at all and I don't know if its had any updates. However I do have a decent knowledge of hardware and modding.

So, lets first of all talk about a possible JTag for the Xbox one.

It COULD be possible, as I assume they have the port on the Xbox one. However I'm assuming they are blocked. As they Microsoft learnt there lesson from the Xbox. However, they might have forgotten or not bothered this is very unlikely though.

So, lets talk about a possible RGH.

Now, if you know what RGH stands for you'll know where I'm going with this. If not it stands for RESET GLITCH HACK now, if you still don't understand read the bold text again. Read the RESET. The RGH was a way to reset the Xbox 360 to run emulate the JTag hack witch was patched. So... Still don't understand? You probably should give up on life at this point but I'll still explain. The Xbox one has just come out, why the **** do you need to reset it? YOU DON'T.

So, I hope this explains everything. However I have never looked into the xbox one at all. I'm just going by what I've read. Please correct me if I'm wrong.
