I know there were some custom firmwares on the old forum, can somebody please share them again.
I'm having trouble with the stock firmware, apps not working anymore, play store stops working.
Did a factory reset this week, google services are working fine for me. Google play store 10.8.50-all seems to work as well, newer version may break Play Store.
Restore stock Play store
Give ES File explorer root rights and remove play store from /system/priv-app/
Copy new play store to /system/priv-app/ and install by clicking on it.
