I purchased an Evo 4G LTE and installed the 126.96.36.199 RUU (stock)
Unlocked the bootloader
Installed TWRP 188.8.131.52
Cannot seem to achieve root. Tried installing several different superuser.zips
The only one that will install without failure is SuperSU-v1.93.zip
No failure but also no root afterward
Is there something obvious I'm missing here?
