K790 to K810

FS and Main have to match I think so im pretty sure if you change one you have to change the other. Someone correct me if im wrong tho

There Versions Have To Match Like R8BF003 Goes With R8BF003 But You Can Use MAIN Of Another Phone And FS Of Another Phone But Its Useless In Your Case.
[Confused...] Let Me Explain.
You Wanna Get TrackID And Photofix. Photofix Is A Function Of MAIN While TrackID A Function Of FS But If You Use K810 Main In K790, You Wont Get Signals:(. And If You Use FS And Not Main, You Still Wont Get TrackID. (Even I Dont Know Why???:D)

Maybe Someone Else Would Provide A Better Answer But I Dont Think So Or If It Is, Camera Would Create Some Trouble Since W700 Lacks Autofocus.
