I'm trying to root HTC Desire 500 Dual Sim. I've been following along this video tutorial: https://www.youtube.com/watch?v=yWLK5XhsVAE
I've unlocked the bootloader and installed CWM Recovery without any issues. When I go into recovery, select "Install zip" and install SuperSU zip, the installation process finishes just fine, it doesn't show any errors, but after I reboot there are no new apps installed and I don't have root access (tested with Root Checker app).
I've tried multiple version of SuperSU (0.96, 0.98, 2.79, etc.), but none of them worked.
Also, I can't mount /system
while in CWM, not sure what it means.
What could possible cause this? Is there anything I can do?
