I just rooted my replacement Hero and rooted it. Flashed CM6 and it just keeps reloading the Cyanogen (mod) screen that has the circular arrow surrounding the Android. I've left it go for 45 minutes and still nothing more, it won't boot up completely. I've tried Wiping everything and for some reason I can't find my Nandroid backup. I can't seem to do anything now. How do I wipe this clean again and start over??
