Flashing ROM's fails

view story

http://forums.androidcentral.com – I had CM10 for a while, but I grew tired of the sluggishness so I decided to go back to CM9. I have tried to flash a few ROM's with both TWRP and CWM, but they all fail so now I'm stuck with stock ICS. I've bever really had this problem before. Suggestions? (HowTos)
