Thanks for the root. I tried to install xposed and I got a pretty bootloop. However flashing the xposed unistaller worked! It’s a pitty to deal with youtube ads…hahaha.
Btw I didnt get that problem with SD card until I flashed TWRP. So I reflashed the custom ROM and unroot & root to solve it. Because of the binary update, I tried with a later superSU http://download.chainfire.eu/supersu-stable It was a couple of minutes ago, it seems to work as the other.
However I’m having problems with Adobe Acrobat. I think I will make a factory reset later.
EDIT: :'( It didnt work, it still “unfortunately stopped”. I think I should change pdf reader app. Did someone use swiftkey?? It is laggy, idk why.
