the original sd card now also doesn't work anymore.
I am getting the feeling that it might be broken, but I would like to try out a new sd card image.

Can I also get a copy of the firmware for this device?
It's a Clara HD from 2019.

thanks
The µSD internal to the Clara HD has the operating system on it. A new µSD card is not going to have that operating system partition so will not boot or do anything useful.

The image I've sent you is an image of the entire µSD card (the free space which is used for serial number, etc., the first Linux ext4 partition which is where your Clara HD boots from, the second Linux ext4 partition which is used for the recovery boot and the FAT32 partition which is the one exposed over USB.

Note that Windows out of the box does not read ext4 partitions and wants to reformat the card which will destroy it's contents when the card is connected directly to a Windows computer.

Once you have the image use BalenaEtcher or USB Duplicator Image Writer to write the image to a new µSD card.

The image has firmware 4.38.21908 already installed. Once your Clara HD is working again, you can upgrade to 4.38.23171 either over the air or by downloading the firmware from the links on Patrick Gaskin's Kobo Firmware Downloads page.
