Flashing Katapult Bootloader and Klipper Firmware on Creality 4.2.2 Board without a working bootloader

I accidentally broke the bootloader on my Creality 4.2.2 board while flashing Klipper. These instructions show how I recovered and how I flashed Klipper and Katapult as bootloader. You can always follow these steps also if you have a working bootloader and could flash via SD card as with Katapult you can update Klipper without the SD card.
