For a full bypass of that crap, you nowadays need a lot of resources including a Secure Enclave exploit - for now they're (relatively) cheap but eventually they'll be the kind of stuff traded for seven figures a pop.
Eternal shame on Google for not insisting that Android would follow the "PC model" of the user being root on their own machine and DRM and whatnot can go and screw themselves. They had the chance of actually delivering something that would not require jailbreaking and cat-and-mouse games like iOS, but they blew it (and blew the MAFIAA instead).
