[How to play FEH on PC (Windows only)]

Right now I'm using the 2.1 Solution and I can't disable Google Play Services (as the disable button is greyed out). I can't access Security options to enable the button either. How did you disable it? @mental_offence
Edit: I've managed to disble it, but I had to root BS3. 
 

[How to play FEH on PC (Windows only)]

Hi,
I've tried the 2.1 method, which is using the Chinese Bluestacks. I did all the steps, disabled all Google Apps. FEH runs fine, but still the 803-3001 error pops up every 20 mins. Is there anything I could be missing?
Edit : Nevermind. I reinstalled the game and it runs just fine now. No idea why.
