lost root access after factory reset

view story

http://androidforums.com – hi all, i've had battery issues in the past three weeks (battery went from great to terrible over night) and finally decided to try a hard reset to see if that restores my battery life. short answer: it didn't... the even bigger problem: apps (first and foremost tib) lost root access. after the hard reset i rooted the phone again with the noxious ninja method, which had worked great before. everything seemed fine, superuser is installed, but it won't grant root access to apps. when booting the phone it even shows the "custom" screen. not sure what to do. any suggestions? than (General)
