I just purchased a Lumia 640 XL (RM-1096). I bought it due to it being fairly cheap and it supports LTE with T-Mobile. The region is Chinese though, so I was wondering if I can flash it with a unbranded US ROM, so it can be completely US and I could get updates when they are released here. I would need the product code for the US unbranded rom, and I haven't been able to find it anywhere online. Thanks in advanced!
