Lost ROOT with 2.3.6 update
So I got my RAZR Maxx 2 weeks ago and after a few days I rooted it so I can use all the cool root apps like wifi tether, titanium backup..etc.. But 3 days ago I got a popup to update my phone so I updated it from 2.3.5, to 2.3.6 and it looks like I lost root access. When I try to open up titanium backup it says it could not gain root permission and there are errors when I try and start the wifi tether.
I can post screenshots if needed but can anyone give me some advise?
