I have previously rooted my ZTE Score and had full functionality with superuser and busybox. everything was fine. then, I accidently wiped my phone and now I cant, for the life of me, get superuser to update the binary to "gain root access". i've tried to use Super Oneclick, Zerg and z4 to "reroot" my phone and all have claimed to have succeeded. However root checker says I don't have proper root access and none of my rooted apps function. I have uninstalled and reinstalled everything from my device and PC a million times to "start fresh" and nothing! please help me because I was sure I had remedied this problem awhile back but obviously not. how can I just start with a fresh root and get back what I knew work as I had before?
