Nitrokey FIDO2 stuck flashing blue/red after firmware update

[march42]

• nitropy 0.4.36
• Nitrokey FIDO2
• Windows 10

update-log.zip

The nitropy output stated error on verifying signature, in the log there is nothing about it. Now my FIDO2 is stuck in bootloader flashing blue and red.

Hello,

Sorry about that. nitropy does not recognize the proper model of the device, and sends firmware from a different one. Please download and use the binary from here - 2.4.1.nitrokey. Unzip it, and use the json binary inside.

Following should make it working again:

wget https://github.com/Nitrokey/nitrokey-fido2-firmware/releases/download/2.4.1.nitrokey/nitrokey-fido2-firmware-2.4.1-128kB-app-signed.zip 
unzip nitrokey-fido2-firmware-2.4.1-128kB-app-signed.zip  
nitropy fido2 util program bootloader nitrokey-fido2-firmware-2.4.1-128kB-app-signed.json  

See this page for the example output:
