Invalid ELF header


One of my test devices is a Samsung S6 and when I try to run from Visual Studio or do a debug attach I get:

Failed to pull device files: Invalid ELF header
Failed to attach: Invalid ELF header

I am using 4.9.1, and I am able to Launch from the Unreal Editor, but I need to debug some code that is failing on Android only and this is stopping me from doing so.

Any ideas?

Found the answer, you have to root the S6 at the moment :/.
