Firstly, a big thanks to @azahidi, who was very generous to share the maps with us.
Met up with him, and we had a nice chat.
Happy to report that I was able to generate the needed FSC code on my own - method should work for all F-series CIC at the moment.
Update went smoothly - and was done in less than 15minutes.
If anyone needs the map or needs help to get this done, do PM me.
Thank you again @azahidi
