How can I re-install Android OS on a Samsung Galaxy Grand Prime I bought from China?

[fjgonzalez]

I want to get the phone to USA android settings, right now it has a ton of pre installed software, some that it wont even let me uninstall. The main issue is that it wont support google play services, which limits my use of the phone considerably, is there a way to essentially get the phone to USA factory settings? Thanks!
