What you probably want is this combined with some privilege escalation technique. If you feel like doing the work, have at it.[1]

If I already had a working privilege escalation strategy, wouldn't I just be able to run that from a terminal emulator program on the phone? Or using an adb shell? My problem is exactly that there is no privilege escalation vulnerability in my version of the OS (that I know of)

Since there are 34 "Gain Priv" listed on that page for Android (many versions) in 2017, and well over 200 listed for 2016, I would imagine with those as a starting point it might not be too hard to look for likely candidates that have been weaponized (or have working proof of concept code) if you search around a bit. It's not exactly easy, but given the huge number of exploits to work with, it would probably yield something without too much work.

I did notice that the entries there include whether there's a known metasploit module, which none that I looked at had one shown there. I googled metasploit and android and found some video tutorial for hacking a Android phone using metasploit from early 2017[1], so maybe that will help you. In any case, good luck if you try.

I think DirtyCOW (CVE-2016-5195) had been dormant in the kernel for a long time. If I remember correctly the PoC demonstrated writing on root-owned files. Might be relevant.
