I would like to know: if I install a custom android on HTC One M8, can I take download the gapps from here? http://opengapps.org/ And do I need anything else besides this? I would also like to know what cpu I should choose for my phone (arm, arm64, x86, x64). I see that my cpu is a Snapdragon 801, which a 32-bit cpu. So should I choose arm or simply x86? Any other tips are welcome.
