I downloaded the stock images for android 2.2 (rooted) for my moto droid from rom manager and installed it thinking it was gonna be rooted. When it finished installing I went through the beginning setup and into the app drawer to see if the superuser icon was there in which it was. So I downloaded rom manager again and opened it and it told me I couldn't be granted the superuser permissions. I clicked the superuser icon in the app drawer and it brings me to a white screen. Just to be sure there was something wrong with my root I downloaded setcpu and I still couldn't be granted superuser permissions What should I do to obtain root access again?
