I own a Sky Elite 5.0L (from Sky Devices), with stock Android 5.1, which apparently cannot be rooted with any app, not even KingRoot 5.0.0 (latest as of December 5th, 2016). Was anyone able to root it? Remind you: it has stock Android 5.1, not 4.4.2.
I need urgently to root it to be able to use Link2SD to make room for apps for work. I offer myself as beta tester.
