Ender 5 pro with mesh bed leveling

Hi, I have a Ender 5 Pro which I have updated to the 4.2.7 board and a new colour rotary knob LCD. I tried using the builder to make firmware which will give me manual mesh bed leveling , linear advance and basically the latest features BUT it failed or a I messed up. My preference is to use the new screen but I would keep the old blue one if I had too. Can someone help me please.
