Help [Lenovo S860]Google Play Store disappeared after system update to KitKat

[rosniah]

Hi. Everyone, I need your help.
At first, I have some problem with my phone (Lenovo S860) and I reset factory. At first, it works well, everything was there. But then, I try to update the system which currently android 4.2.2 to 4.4.2 , but when I successfully update to 4.4.2 android version, all Google apps are gone, including Google Play Store. I then download the Play Store APK of latest version and after install, I click the icon but nothing happen. It goes back to home screen. I also download the Google Play Store Service and install it and click the icon but then it says, Google Play Store Service is not working. I tried to restart the phone but also nothing happen. The icon still there, can click but still it goes back to home screen. I also have tried to check at apps setting in case it was disabled, but no it wasn't. It is in enable mode. Its seems like something is blocking any google apps from working. I'm not sure.

By "updating" do you mean you installed a custom rom or was it an official update?

official update by phone. the phone says there's update for system (for phone and android version) so I click, it takes a long time to finish, when it restart my phone the android is now from 4.2.2 to now 4.4.2
