I never used this chip because I decided to get a matrix instead. I believe this is also the latest version of the Enigmah chip but I'm not sure if it's compatible with version 1.1 I bought this chip at extreme-mods.com So head over there for instructions. I also can't offer any garuntees and sorry no refunds. So if you screw up your xbox or if the chip doesn't work your out of luck.
I'm selling it for 25 + shipping or Best offer.
Buyer with good experience on modifing an xbox preferred.
