I installed the Sprint 2.1 leak RUU and then rooted. Probably backwards, but everything has been working great for the past few days regardless. My problem is when I try to use something like Titanium Backup. I get a message saying that "busybox works but the "su" command does not elevate to root" It goes on to say my superuser whitelist system app does not work. I tried to install the superuser whitelist app from the market but it said it was incompatible with my phone. What can I do now to get Superuser privileges?
