Last FW of Git only LCD does not work normally

I am using NanoVNA V2 Plus 4 version.
It uses a 4" LCD.

Clone the last F/W in Git and compiled it.
After downloading this, the LCD does nothing.
However, I saw that Sweep works normally by connecting via USB from the Nanovna-Server.

I would like to edit the source and add some other features.

When I restore with
nanovna-v2-20210726-v2plus4.bin everything is fine.

nanovna-v2-20201013-v2plus4.bin
When restored to , nothing is displayed on the LCD.

What's the problem?
What is the solution?
please help me
thank you.

First of all thanks for your kind reply.

I want to modify the source to add communication protocol.

Now , is the final source code other than the compiled bin file not being released anymore ?

As i know last hardware have different lcd module, no open sources code or information about lcd avaible. But connection work, so you can conrtol V2Plus4 on CPU side.

I think possdible use this sources, if replace lcd, need search 4inch st7796 module.

Can the display be flipped? I don't like running the VNA with the cables
facing down. (I don't have one yet but that would be a show stopper if
it can't)
