Ok so i just rooted and installed ROM manager and did a backup on my stock rom. I downloaded cyanogen mod 7 and rebooted to get it going, but i'm stuck on the skateboarding android dude with the cyanogen mod 7 screen and it just keeps coming up over and over. I went into recovery and tried to flash my stock rom but it says the file cannot be found when clearly it took about 5 mins to back it up it should be there. I need help
