Root exists, but is unusable One of my long-standing issues with allwinner Q8 is how its root, which was there when I brought it, can't seem to be used. No root manager came with it, so I installed SuperSU(Like a normal) to find that nothing can make requests at root. I can't even check the binary since I get a 'access denied' every time. Does anyone know how I can root functioning?

Again, Its a 'rooted' Allwinner Q8 On android 4.4.4 With stock recovery (but I'm 45% sure it has a custom ROM.

-EDIT-

An idea from Steve made me check terminal, and I ran su to get the line:

su: uid 10078 is not allowed to su

Errr... What? I assume the user is UID 10078(would make sense) or the su binary has been locking everything. Its only a one-user (in sense of Physical operator of device) system.   Help!
If your phone does have a custom ROM have you looked in settings under the hidden Developer options menu for a switch that disables root access?  Some custom ROMs will have this hidden in there.  Everything can be in place to grant root, but apps won't get root if the switch is set to "Disabled" they may not appear to even request root from the SupperSU app.
