Mine always go the last channel I was on
If i was in favourites it goes back to favorites

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 waited until chrome reinstalled and then restored my settings and server info
Google play is now working
