I bought a VW Android 9.0 Pumpkin head unit from its official website.
I want to full control over it and do what I want.
So I asked Pumpkin Customer Service the developer code to enter the developer mode.
But they told me they did not know the developer code.
It is a little disappointing for me. However, Pumpkin solved this problem quickly.
They offer me a solution to enter the developer mode without code.
So I want to share the way to all of you. It really works.
