Hm, I think I knoiw what's wrong. After rooting, I was sick of always being bugged about the OTA, so I installed it. Now I'm on ICS 4.0.4. I need to do the Rooting the 4.0.4 update part at the end of dmmarck's rooting guide, don't I?
What I don't know is if I have TWRP on the ohone, if I have no recovery, or what to even do once I can get into recovery. The last part of his guide that I mentioned says to download su.zip to my internal storage, so that's to the phone? But then it says something about SDK/Tools or a Platform-Tools folder. Is this on the phone, and I'd need to use a file manager to get there, or is that the same as the root folder I made and used for Superboot?
Bingo. You do not have root. You need to follow the guide portion which has you flash/boot into a custom recovery, as I said before (TWRP recommended over CWM). Flash the SU package available in the Rooting guide. Then you'll be rooted.
