Lollipop Rooted knox OxO but the root is kinda useless topic

Hi guys so I have recently taken the ota for lollipop after being unable to use mobile odin pro to update to lollipop and keep root. since mobile odin does not flash bootloaders and hidden files the phone simply would not boot and was not going into recovery mode either.

Today I was able to solve this by

first step I odin flashed the ne6 firmware I had to factory reset the phone to get It to boot after downgrading from
then I towelrooted and installed mobile odin pro
next I used mobile odin pro to flash the lollipop firmware but instead of letting the phone reboot after the flash, I set mobile odin pro to reboot into download mode instead.
from there I pc odin flashed the modem/bootloader file or "firmware only file that Artizan made here http://forum.xda-developers.com/tmob...-file-t3036102
the t mobile screen was taking a long time so I factory reset and then it booted fine
now the strange thing is supersu was able to update the binary and grant permission to both root checker and busybox but neither app is acting properly . they both say that they were granted permission but busybox is not installing and root checker just hangs. oh well at least phone info and cpuz recognize that the phone is rooted but so far root apps are not working properly
