Big up again goes to Thorz.
I'll just walk you thru how i used the files he provided to update my squads. His way is 100% i just happened to skip a few steps
1. Grabbed the files and unzipped to PC
2. Fired up RGH console and used ftp to grab a game save. (Any gamesave will do under your profile) In my case I just grabbed Fifa 14 squads
3. Fired up Horizon on PC and dragged Fifa 14 squads onto it. (This step only serves to get you Profile ID and Device ID)
4. Armed with the above info follow steps 5, 6 and 7 as explained by Thorz
5. Move onto step 9 as explained by Thorz
6. Grabbed title update via FSD
7. Fire up Fifa 15 its done.
I would suggest y'all bookmark this because come Feb you will need to do this all over again after Jan transfer window.
