SKR 3 EZ firmware and bootloader not updating

Basic Information:

Printer Model: Voron V0.2
MCU / Printerboard: SKR 3 EZ

Hi, I have an issue with a SKR 3 EZ which is not updating via SD card.
Printer was working fine, I updated via Kiauh and got the message that I need to update the firmware, I took the opportunity to install katapult bootloader and I am concern I did something wrong because the board is completely unresponsive now, no cano interface, no ID , if I try to flash again katapult in dfu mode I just receive an error message that is not able to mass erase before flashing.
Anyone know what can do?
Is there other way to flash the bootlader?
Many thanks… (423.8 KB)

Sounds like you will need a STLink to recover the board.
