Nokia RM-937 Owner's Thread

[pholad]

Hello everyone, I lately bought a Lumia 1520 white color (RM-937). I am using it in the US; the phone came with a ROM from Yemen. I flashed the phone to a ROM from Finland and then the UK (both ROM are country variant). My phone get connected on both Cricket Wireless(Which uses AT&T network) and T-mobile to HSPA+ speed. I am not getting LTE; This is not a big deal for me since HSPA+ internet speed is fast enough to get what I need done. I would like to get recommendation as to which ROM (Country Variant) is better suited for use in the US. I already know the whole process of unbranding (Flashing Lumia phones). My phone currently has UK Country Variant ROM installed.

Flash it with Att ROM RM-940 THEN from dial pad dial ##3282#
Accept the field Test and choose the setting and then choose the network type
Choose Maul and click tick mark all the band that will activate all the LTE and AWS bands

New 937 owner here... on T-Mobile.

What is the procedure for flashing the 937 to a 940 ROM so I can enable the 1700MHz band?
