[Android Software/Hacking General [Developers Only]] Pkt_Lnt:
I just experienced the same thing with checking "use root" in Tasker run shell give the no root error in beta 8. The phh app from the Play Store works fine without the error from Tasker.

Here is a logcat, filtered for Tasker. Let me know if you need a verbose unfiltered one.
