Installed ROM for Moto X-Force and doesn't recognize carrier

[cfrenzel2010]

Hi, everyone!
I recently bought a Chinese Moto X-Force (XT1581) and after trying to update Marshmallow with XT1580 for Latin America (I'm in Chile), I get this message over and over again, after installing the new rom

I just don´t know what to do...

The firmware I used is original and compatible with the region l live in.

Any tips?

Thanks a lot in advance!
