Hi my name is ***** ***** ill be helping you with your issues today.
If you have rooted the device, but you have no functionality of the device, more than likely, you would need to do a factory reset of the device and try the root again, as something didnt take properly. We dont do much support for rooted devices as it is a change to the original software of the phone and is very difficult to troubleshoot, as we would have no idea what is loaded on the phone.
however, a factory reset should resume functionality of the device and you would be free to try and do the root again if you like.
If you need, I can research and supply you with information to do a factory reset for your device.
are you still needing assistance with your issues?
