So I have been trying to flash CM9 for the past couple of days, at first it worked just fine but I forgot google apps, so I went back to recovery and flashed gapps. After that it wouldn't leave the boot screen. I used odin to put a stock ICS rom on, then flashed clockwork and now every time I try to install cm9 It just stops on "installing." Did I miss something very simple and obvious or what?
