How to upgrade the firmware on Ender-5 S1 3D printer? (And why to wait with it)

This is add-on video to my Ender-5 S1 review. In that video I mentioned that homing of the Z axis should be better if it uses the CR-Touch and not the bottom limit switch. I got several tips, that new 1.0.6 firmware should fix this (but so far it has other errors). So, let&test it.. In video you can see a method how to reduce the noise from the buzzer and how to make interting of the filament more smoother.
