one of the best hackers out there said that an updated box is probably non-hackable i think the same thing unless m$ introduces another hypervisor bug then were screwed for now, and by now ms probably checks every single update carefully
yea, mw2 exp lobbys are a waste of good kvs I did it with a keyvault a bunch of people ripped, and all were going to get it banned anyway, but I didnt buy in to this whole $$$exp$$$ ******** thats been going on unfortunately once kvs run out.......
i would always try this, then fall back to lpt as this is way faster(flashes in 10sec or so) it can really do harm except screw up the nand, which can be fixed by re-flashing from lpt
