[Q] No root after last update (SuperSU binary not installed) topic

Hi there!,

I installed Cyanogen ROM, I tried it for a few days and I liked, but I loose a lot of sound quality using bluettoth audio.

I think the Aptx bluetooth codec, insatalled in stock rom really works.

I have all my music in my phone so I decided to come back to stock and get the aptx quality sound.

I tried to install xposed today but I get a message telling me that I have no root access.

My SuperSU tells me that binary SU is not installed.

Does the last ofifical update change this binary???

How can I restore it?.

Many thanks in advance.
