So, I am using a Samsung Galaxy S5 (SM-G901F). I wanted to upgrade the firmware manually through odin. I have done this multiple times, but this time, when I clicked in AP and tried to search the file, odin just seemed to not be able to find this file. I downloaded the firmware from Sammobile, extracted it and that is all. I really hope i get help as I am really desperate for this Marshmallow update. Thanks
