H2D Firmware V01.03.65.00

You are referencing models here.

The update process is a black box process. It downloads and installs the firmware automatically.
This all happens ftom the internal memory.

There are no options to save the firmware to a USB.

Additionally: Bambu would not have control over who has the Beta installed.

I have the same issue as well. I order the star PTFE tubes to fix this problem. I haven’t received them yet. I will report if this solves the problem.
