Does it matter what varient the phone is though? Here is the one for sale on Amazon: http://www.amazon.com/LG-G4-Unlocked-Leather-Warranty/dp/B01774WPQ8/ref=sr_1_1?s=wireless&ie=UTF8&qid=1458967317&sr=1-1&keywords=lg+g4 (not sure if that is aloud). But nonetheless, I am unsure what version of phone that is, and also what version of android it is. But as you said, that can be downgraded.
