I unrooted the telephone and rooted again with Vroot. Installed SuperUser but when updating binary a download error ocurred. Anyway, I tried with the chinese application and now, Titanium works, Mobileuncle tools works (I can make copy of imei) and Root Browser works, so definitively, the problem is related to SuperSu permissions. I'm not able to make superuser work.
Why you messed the phone uo with vroot?
Just install the newest superuser as zip in recovery. Thats all.
