officially rooted from htcdev.com, I followed the instructions step by step and had the screen confirmation that my phone (HTC Sensation XL) is rooted.
Now when trying to gain super user access through "Android emulator", "Superuser", "Super manager" the permission is denied or the apps cannot detect if the device has been rooted.
I want to know why root access is denied after the device has been rooted successfully and how to fix this issue, am I missing extra steps or additional settings?
