Hi, having some problems with lg p 509. Am still awake at an ungodly hour trying to resolve issues. I ran gingerbreak, have superuser installed, following instructions on xda website under how to root. I'm pretty sure I'm in adb shell, but when i type adb shell su, or adb shell sudo su in command prompt, answer is always "permission denied." Root checker says I have root, but can't obtain superuser permissions. Have checked many threads, but haven't found remedy yet. Can anyone please help me? I will wait till reasonable hour for response.
