you tried already?

cool, trying now. thanks.

edit:
and now I'm stuck at step 28 where my contact is not syncing. And step 27 is quite not understand.

me too, but you can manually sync your google contact to your phone, so its just a small matter for me, not big issue..
or setting - app - google play - permission - contact - allow

27. Then click on the Google Play store to display all the software icons to download the software. If it is blank or cannot be opened, please wait patiently for your phone to wait for Google Play to update automatically.
