As the root may involve installing of a dozen different versions of the Android or other OS, no one should be able to support you EXCEPT those that did the root or those that have a web site or forum for that rooted OS.
Let's hope you know where you got this rooted OS from so members here can help you find the author and hopefully the forum where you can get more help.
Not having much money I bought a used Rooted MetroPCS Samsung Admire SCH r720 and noticed the WiFi or the blue tooth will turn on. I took the phone to MetroPCS and was informed that the phone had been rooted. Is there an app that I am to install? If so, how beeing that I cannot access the web do to the WiFi?
