Good day gamers. I need your need help.

So I got the Fifa 18 and Pes 18 games but on trying to play, it asks for a 4.80 firmware or above update.
The problem is, I am on HABIB_476_COBRA_V1.00.PUP firmware. I have once updated the system to 4.8 and I had to go downgrade it. I want to avoid downgrading the system again. Please, is there a way around it.
