Today, I installed Titanium Backup and I've had some problems. First, it couldn't get root access. I know I have root, so I pushed "problems" and installed busybox from there. It worked after that for awhile. Then, I just try to go into Titanium to do a backup and it's telling me to turn on debugging mode and allow unknown sources. I already have both debugging mode and allow unknown sources ticked on. So, I went back to settings and ticked them both off then on again. I go back to Titanium and it works fine, but only once or twice. Then, it gives me the same warnings again. I remember reading something about installing busybox from Titanium causing problems, but I don't know where that was or if it applies here.
