Oem camera X4 G02

[Rapha65]

Hello Team
Owner of a Bmw x4 G02 M40d end of 2019, I’ve forgotten to order camera when i ordered this car so I bought an oem front&rear camera kit. https://www.phibu-electronics.com/module...2x27746441 Which was working like a charm during 2 years
Last october Bmw recall my car for a software update and after that my camera were not working anymore.
I am newbie in Bmw coding but i am quite sure that i could make these camera work again but for that i need help 

I ve got an Enet cable but i don’t know how to begin

Which program ?
Which option to code ?
An so on…

Please help !

Thanks
