How to update Google play services on Xgimi H1 :

First install Kodi from USB (download and install  Kodi APK), open Kodi, inside Kodi go to Addons-Android Apps and open Play Store from inside Kodi. Log in with your Google account. If you dont do this before updating later you will not be able to add acount. You will have to Factory Reset your Xgimi and start from beginning.

1.) Go to Settings-System Information window.Hold left button for cca 5sec until hidden menu appears, switch ADB value to the right until this symbol (I guess it means enabled) appears :
