Just some thoughts and speculations:
Well according to what i posted before in this thread, some questions to the non-noobs in hacking/electrics:
1: Do retail x360 still need/have some jtag(?) repair-service connection on the mobo?
Yes. JTAG is used for many different things including chip testing, board testing, and in-circuit emulation. The in-circuit emulation may be disabled by an eFuse to prevent security breaches. Board testing isn't very useful in attacking a system, but the chip testing is. Think of every storage element (flip-flop) in the chip connected as a huge shift register that you could load with whatever values you want. Properly timed you can change the result of a comparison (calculated key == stored key?)

2: If they do (probably they have:
http://forums.xbox-s...owtopic=468242) the exact connection points are still unknown?
3: if they were known, could u use that tiny pcb, 4wires at the right places from the pcb and maybe do a TRST (Test ReSeT) for emulating/rebuilding a M$ service-remote?
Yes.

4: Could this set the hypervisor into a sleep-mode aka. OFF?
No. The hypervisor is a fundamental building block that everything in the system is built on top of. If you remove the hypervisor you can't access the disk, video, dvd, etc. What needs to be done is convince the hypervisor the XEX file it just loaded has a valid signature. From then on the XEX will run as normal and can show pretty pictures on the screen.

5: Would only EX-M$ in x360 department know the exact connection spots?
No. Draw a schematic of the various chip interconnects, and test each one in turn until you find a TAP controller. I've got the IEEE JTAG spec around here somewhere, but a few minutes in the IEEE webstore would give the number of the spec to buy. Assuming they didn't disguise the JTAG port.

6: Would you mask yourself if you were an EX-M$ showing some breaking news in x360 hacking?
There are so many levels of pain MS could apply to an ex-employee nobody would be stupid enough to pull a stunt like that no matter how good the disguise was. Get three buddies to cover their faces and put hoodies on then walk around a bit. I'd lay odds you could tell the apart from the way they walk and gesture.
Somebody knows who Hoodie is, but probably are in on the show (or scam?) and haven't squealed yet.

7: Would you still need that kingkong (demo?) game? - NO, you wouldnt and this is where i recon my post is wrong!!

I haven't seen the game. Can anyone tell from the startup screens if it is the demo or the full game?
