H06-L12 Android 5.1 Stable rooted - But how Busy Box works?

Hello,

first thanks to all for this great board!

I installed the new Android 5.1 Stable and root it again. All great.

On Android 4.4 I can install BusyBox (i think via Recovery). But now i tried so much times and it never worked. Somebody has an idea, how busybox can run?

Thanks.
