Need some help finding flash files to debrand some older w810i and w580i to make them more "useful". ie remove annoying Rogers branding and bloat-ware, and allowing the use of MP3 ringtunes. I've already unlocked both using remote codes.

From my research, I'm guessing I can jump between CID and Firmware versions as long as I keep them the same between the Main and FS files used??? How does one tell if a firmware is older or newer, are they numerically/alphabetically higher?

I've already used XS++ 3.1 to do a GDFS backup. Here is the info on the phones:
