Default [Q] flashing c6906 firmware onto a c6903

what do you think will happen? will I get the ability to use band 4 and 17 for optimal at&t lte usage? right now i get intermittent lte with my c6903 in miami. I tried to flash just the baseband of the c6906 firmware and it took like 3 seconds and nothing really changed. while I do speedtests with friends next to me with their at&t branded phones their lte is just faster then mine most of the time. what do you think?

Bands 4 and 17 require specific hardware that is only available in the c6906. So no, you cannot flash a c6906 ftf on your c6903 and expect bands 4 and 17 to work. Your friends might be getting better cell reception as compared to you but.your speeds should be pretty much same.
