How to add/Enable T-Mobile 3G/4G AWS Bands on SM-G900V?

[shahrit]

Hi,

I have SM-G900V Verizon Samsung Galaxy S5 and currently downgraded it to NCG from OC4 and is rooted with towelroot. What I want to accomplish is to add or enable Tmobile aws/hspa/umts 1700/2100 mhz band (Band IV) on it. Is it possible on the currently rooted NCG firmware? If so, any step by step guidance or direction to existing thread please?

Thanks,

Ritesh
