Solo Key not recognized

[lambaradan]

Hello. I was redirected here by Haden at hello@solokeys.com.

I have just received a Solo Key USB-A via DiceKeys. I used your Python command line app to update the firmware, and I think this might have been a mistake. It was v. 5.0 something when I got it, and when upgraded, it was upgraded (??) to version 4.1.2. Then I had trouble in the command line app adding a credential...

I then found your GitHub tutorial on DiceKeys Seeding WebAuthN Authenticator Credentials and tried to run that, but now the Solo Key is not recognized.

How can I reset it totally in a mode that it will with with the DiceKeys app? Holding down the button while inserting the key and waiting for the blinking light produces no light.

The Solo Key is not recognized by the DiceKeys app, or your python command line program. The error message is: "solo.exceptions.NoSoloFoundError: no Solo found" in response to a "solo key verify" command.

However, on my Mac Mini in System Information, the hardware is detected:
STM32 BOOTLOADER:

Product ID: 0xdf11
Vendor ID: 0x0483 (STMicroelectronics)
Version: 22.00
Serial Number: 208F31A15653
Speed: Up to 12 Mb/s
Manufacturer: STMicroelectronics
Location ID: 0x14300000 / 28
Current Available (mA): 500
Current Required (mA): 100
Extra Operating Current (mA): 0

Please help.

It looks like it is in DFU mode.

Run these two commands:

# program firmware
solo program dfu bundle-hacker-5.0.0.hex

# reboot
solo program aux leave-dfu

Do not run the later command if the first command doesn't succeed.

@conorpp Thanks for your rapid response.

Can you try again after installing libusb

brew install libusb libusb-compat

For this you will need to download the firmware file and provide the correct path.

Download: https://github.com/conorpp/solo-dicekeys/releases/download/5.0.0/bundle-hacker-5.0.0.hex

cd to your downloads folder and run the command again.

Success! Solid green light now. Is the error: Warning: OSError with write_page" anything to worry about?
Key is recognized by the DiceKeys app and was successfully seeded.

A big thank you Mr. Conor!
