right now i'm on a plain jane 2.0.1 rooted rom. i've downloaded cm updater from the marketplace. i open it and it says no roms found. i click update and it doesn't find anything. i downloaded cyanogen_sholes-ota-eng.koush_188.8.131.52.zip and place that in the cmupdater\updates folder and it still doesn't find anything. how the heck are you supposed to use this thing?
