Ok, I'm having some problems with rooting my friends Thunderbolt. I tried to root via Revolutionary, but I kept getting stuck at the very beginning I would just get a fail. So it tried to root via htcsupertoolv3. It seems to work, but I kept getting errors trying to start wifi tether. Well I knew what the problem was, I needed to update the su-bin, Superuser was messed up. So I tried to update the su_bin via recovery, but I get an error and a reboot when I select update via SD card. I obviously can't install Rom Manager, bu cause it requires Superuser to work. I did notice when I boot into recovery, that I'm not in cwm recovery. I even tried to unroot via htcsupertoolv3 and that is unsuccessful. If I can just update the su_bin, all should be fine. Any ideas?
