I have a legacy OnlyKey, and just found out that you have disable the Chrome version. I need to configure a backup passphrase, but I can’t put in config mode. When I go to Chrome OnlyKey, the software prompts me to download new firmware. Is there anyway I can put OnlyKey to get in config mode so I can create a backup?
The original non-color onlykey was discontinued in 2017, is that what you have? You could use the app from 2017 here - Release OnlyKey App Beta 5.0 · trustcrypto/OnlyKey-App · GitHub
