I have read many posts on this and other forums that offer ways to regain root after the ota 2.2.1 update for DX. It seems that the z4root option is highly recommended but I cant get it to even open. I have followed a few links in this forum and finally got it to download to the phone (using my phone to dowload to) but when I go to open the apk (by clicking on it) it errors saying that it cant parse. Thats as Far as I get. What am I doing wrong?
