so i know when other update versions have come up sometimes there is talk of rolling back to get root again, but for the most recent update to the D1 i havnt been able to find anything. i rooted my droid with z4root and everything is great, but now my brother wants to root as well. but z4 doesnt seem to be working because he is updated to stock 2.2.1 so i was wondering if there was a way to roll his phone back to 2.2 so that he could use z4 on it.
thanks
