[Q] Root 5.0.1 ? topic

Hi all...... I have just got a breif question maybe there is no root out yet for 5.0.1 or I am just being stupid but i had 4.4 rooted and updated to 5.0.1 lollipop i do have a custom recovery being twrp, however i cannot install the binary i get ......

There is no binary installed and supersu cannot install it. This is a problem !
if you just upgraded to android 5.0 you need to manually re~root consult the relevnt forums...

i have tried uninstalling super su but it wont uninstall as im not rooted... i have tried manually installing the supersu binary.zip from sd card
and tried installing a different supersu nothing will work any ideas people

many thanks michael
