I rooted last night using RegawMOD, which went pretty well. That process installed superSU, but when I try to use Titanium Backup, it says the device isn't rooted. The SU app itself says it needs to update binaries, but each time, the installation fails. So far, I have tried a fresh install from the market, clearing data and preferences, etc. I've even downloaded the .zip from XDA, but when I reboot into TWRP, I can't seem to find the superSU file to flash from recovery. Anyone have any ideas for how to get this to work?
