Flashing Lumia 920 with RM-820 unbranded

[Fellipe Abib]

Hey everyone..

I bought a lumia 920 on AT&T when I was in US, but I live in Brazil.
There is no problem being AT&T (already unlocked), what I really want is to flash my L920 to a new RM-820 unbranded..
I have all the tools to flash (nokia care suit, navifirm, etc.) But my big problem is:

I DON'T KNOW WHAT FIRMWARE TO FLASH

I'm confuse.. I don't want a Rogers ROM, euro ROM or even Brazilian ROM.
I want an american unbrande rom. I saw on navifirm a "059R4W6 - Global black swap"
Is this rom a global no contry variant and no carrier on it?
or what ROM do you, guys, suggest to flash my phone since I don't a boot logo or change my RM-820 to a RM-821.

I really don't think 920 was officially launched in USA unbranded? but there was a guy who posted a thread about flashing generic rom to att 920, search it
