how to make my m2 working with 800mhz 4g?

i was wondering how i could add the 800mh*z frequency support on my m2 and also i wanted to ask if this restriction was only firmware related or hardware related… because as far as i know the mtk6735 supports the 800mhz 4g frequency…
that’s all for now ^^ thx by advance for any responses

Meizu MX4 Pro

i dont want to disappoint you but i dont think this is even possible :( meizu doesnt add this frequency to its phones cause its cheaper to leave it out and in china where their phones are sold most often they dont use band 20
