Ok so i rooted my droid 1, and have been liking it, but its just a little slow for me. I know the update is rolling out for the droid so i want to go back to 2.1 and unroot. I unrooted my droid, but my 2.2 custom rom is still on. I deleted the rom from my sd card and everything. How to i just return to how my phone was out of the box? I am unrooted now.
