Ender 3 S1 Pro not flashing firmware

I registered especially for this post because I bought an Ender 3 S1 Pro and wanted to flash Klipper. But it does not work. Not even the original firmware can be reflashed, which means that Creality's official firmware updates can also not be installed. Nothing happens!

And it seems that I am not the only one with this problem. On reddit and other forums there are people who also report about it.

My Ender 3 S1 Pro has the new version with the STM32F401 controller board. The older F103 can be flashed. Btw, there are also S1 (without Pro) but with F401 which also can't be flashed.

Does anyone have a solution for this? Or is the printer practically dead?
