When Google first released movie rentals on Android devices it was stated that rooted devices will not shave the ability to play these rentals. Just like all other features that manufacturers, providers and developers try to block or lock down the Android community has found a way to get around it.
“This bypass doesn’t affect the actually DRM licensing, it will still generate a proper license key, you will still be limited to the normal viewing times, you will still have to pay to rent movies, etc. Don’t ask, because it’s not happening. It just bypasses/disabled the root check.”
