i have a ms28 that i flashed with xtreme 33, it was really rough noisey so then i flashed it with xtreme 52b, still really rough and noisey so i flashed it with xtreme 52a cuz someone said that his how his shut up, it was even more louder, but not a s rough, so then i got pissed and flashed it to 52b again, NOW IT SHUT UP!!! what was the problem!! i need to flash my friends ms28 so i don't want to get his stuck really rough and noisey. TRUST ME THE NOISE WASN'T NORMAL MUCH NOISER THAN THE 360's FANS and MY DUAL CORE PC!!! It seemed like the firmware was corrupt thats the kind of the noise!! THAT NOISE DOESN'T EVEN USED TO COME WHEN ORIGINAL USED TO LOAD AT FULL SPEED!!
