Thanks for your help guys. Nothing is showing up in the apps list in the superuser app. I haven't purchased the prokey for TB yet, I wanted to make sure it would run ok first.
I'll try reflashing the superuser files. Just so I'm clear, is that the same as in step 3 or is that the option in the amon-ra recovery menu? If it's step 3 from the guide, will I need to wipe everything again or just flash it?
