I've had no problem rooting my previous DX along with my girlfriend and friends phones as well. I've also never had a problem when I was on blackberry. I've been to every forum I could find and downloaded and installed so many different RSLite programs along with .340 files. I keep on getting a fail when I try to sbf my phone so I can get it rooted. I've been doing this sort of thing for years and fully read all instructions so I know it's not me. Are the new replacement DX's locked or something? Any help would certainly be appreciated.
