Any recommended build for Nvidia Shield Tablet K1?

[molul]

Hi all. I apologize in advance if this question is so outdated, but I want to try Dolphin, and after a few days reading a lot of threads (in these forums and outside them) I still have the same doubt: is there any (old) build that currently works (more or less) fine on Nvidia Shield Tablet K1 with Android Marshmallow?

I'm aware that Dolphin 5.0 started the 64bit road and so Shield K1 can't run it because it's 32bit. However, I've seen people saying some old builds worked fine, while in these forums some have said that "no way".

I've downloaded a lot of the 4.x latest builds, but with all of them I get the message "App was not installed", and it's not a matter of enabling that Android setting that lets you install apk's from outside Google Play (I have it enabled and I've installed some other apps with no problem).

Could anyone confirm if I could run any Dolphin version on the Shield K1, and if so, which build should I use?

Thanks in advance

64-bit only started long before 5.0, you could find a version that works, but it will run poorly.
