just updated. This firmware doesnt play nice with google play services.

Yep… Had to go back to the older version and clear all data… Wouldn’t recommend this one.

@nextman @balisto how about this fix?

My solution is very simple:
I used banks gapps minimal: Banks Gapps minimal

1. Download and extract the archive to your device
2. Make sure you have ROOT access
3. Copy the files to their respective ‘/system’ folders
4. Make sure the permissions for the files are correct (rw–r--r–)
5. Reboot
6. Sign in

@HondaRacer, installation method - good guide
@Banks, gapps

I don’t want to root, last time my mx2 slowed down remarkably…
I’ll just wait for the next update and hope it will be fixed. :)

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
