restore to factory

[nasa1303]

ok, since i am pretty busy this weekend i don't have hours to sit here and fool with my moment. was going to do the cl14 update and my driver wasn't installed properly so it wouln't read my phone when it came time to plug it in. how do i restore it to before i screwed with it. it just sits on the screen that says android and it won't finish booting. is there a stock rom file or something i can do
