New Mi3 WCDMA - SU problem with some apps

Mar 7, 2014
I'm having problems with SU permissions in some apps on my Mi3 WCMDA. I'm using the last multi version (4.3.14).
When it ask me for the permission I allow it, but the app gives me an error that says I must be root.
The apps are dSploit and Network Spoofer, which worked well on my Wildfire S. I'm not having problems with other apps, so it's a bit strange.
PS: With earlier versions of the ROM I had the same problem.

EDIT: I solved the problem, just installed a previous version of BusyBox.
