[BOUNTY HERE$] G900P No Mobile Data Connection topic

Hi, I have a Samsung Galaxy S5 G900P, I bought it from eBay on the United States and right now I'm using it in Dominican Republic (The caribbean).

I unlocked the phone with the SSU, I get SMS and Voice, but not data. I did this tutorial http://forum.xda-developers.com/spri...5-gsm-t3025871 and it solve the problem BUT the phone is rooted and FingerPrint Scanner doesn't work.

I mean, why does data works with Custom Roms and not with Stock Roms? Maybe this can be the answer to this thread, but I'm not a developer.

IS THERE A WAY I can have Data Connection with a Stock Rom installed?

PD: I'll give 20USD$ to the one who solves this.
You can write me this via to help ALL THE PEOPLE who have this same problem or message me to hosni_calderon@hotmail.com

Thanks to all the people who work so hard to bring solution to us, people like SSU creator and all this tutorials on this page, we feel very thankful.
