Oppo Find X9 Pro and MoreLocale2

Hello everyone! I just received my Oppo Find X9 Pro which i bought from Giztop so it's the Chinese version, but I've made it as western as possible and I'm genuinely happy about my purchase. I don't mind it being in English only, but it'd be 10/10 if I could enable Danish in system languages. I tried installing MoreLocale 2, but I couldn't get it to install. I followed the guide on TradingShenzen.

Has anyone else had luck in doing this install?

Another thing, double tapping the power button opens the Chinese "cards" app even though I've made Google Wallet open on double tap. Again if there's no solution it's not the end of the world, but it would be a nice to have.
