Save your server info and settings to usb first so you don't have to reload all your info
You will lose any loaded apps
You will find factory set in settings
I backed up my servers and settings to usb and did a soft reset
I waited until chrome reinstalled and then restored my settings and server info
Google play is now working
I am having same issue with Google play I did get to a screen where it asked which account I used the mouse to say ok and it stayed at black screen
