After obtaining ROOT through VROOT process I STRONGLY urged not to install from Playstore SuperSU or Superuser (western version) since it requires installation of busybox. The wrong implementation of busybox (should it be in /bin or /xbin) will render the internal storage to be inaccessible and any update is not possible (with "insufficient storage available" message).
I love SuperSU so much in all of my Android (5x in total) that it screwed up my A880 with "insufficient storage available" messages all the time.
Anyway I was on 013 build and this one, we are fretting about is 020 version. Although without Gapps I did manage to have a fully functioning Google compatible A880 phone with full access to Playstore/Search/Gmail/Maps
The advantage of using the Chinese Superuser is it has a buildin customisable firewall, it doesnt need busybox to operate,(that is why our prerooted devices with SuperSU keeps losing root)it has build in system app uninstaller.
I am happily using the Chinese Superuser without any problems to my apps that requires root access.
