HI, I'm new at rooting, and i attempted to root my Ally with gingerbreak 1.1. i have superuser and root access, and deleted some bloatware for more internal memory. but now i want to install Velocity 1.1 onto my phone. do i have to unroot my phone first, and how would I? can i install velocity without the GUIDE? or is gingerbreak the same as the 2.2.1 Froyo downgrade thing?
