So I have installed the uc5 12" screen upgrade in my 2020 ram 2500 following the instruction from @Arben72 on his post (DIY convert your 19-21 to 23-24). I followed everything he said and the radio is up and running properly from what I know. I also bought a new 360 camera module 56029965AC per @Jimmy07 instructions to ensure I don't do anything wrong. On my truck I am using obdlinkmx+ to communicate to the system and can pull up what is instructed too, but I run into a problem. When I try to tell the system to change the year of the truck bcm to 2022 instead of 2020 as @Arben72 instructs (5. Open and connect to alfaobd, under bcm, change model year to 2023.) I see it shows 2020 but will not save or change to 2023 or 2022? I am missing something here or what. I have read these instructions over 50x times and still can't change. My truck is currently deleted and has an Ezlynk with a security bypass on it I even disconnected the Ezlynk thinking it was maybe interfering with the changes but nothing will work.

Im currently at a standstill if anybody can shine some light on this, just trying to get my truck back working again.

thanks, guys
