Sorry.. but what's the E66 error, and what's the MS25 validation? I have the MS28 drive.. can someone give me more info on what the purpose of this is?
If your 360 came with an ms25 drive, but you flash it with an ms28 firmware such as Xtreme 5.0, you'll get error 66. Same if you have an ms28 drive flashed with an ms25 firmware such as Xtreme 3.0.
If your 360 came with an ms25 drive, and you flash it with Xtreme 5.0 which has been patched to report its version as ms25, problem solved.
You won't have a problem anyway as yours is ms28, unless you flash with an unpatched Xtreme 3.0.
