I spent some more time on this, and I got together something that should be reasonably easy. I can’t guarantee it will work, and I provide this as-is with zero warranty - it has not been approved by Goodix, the manufacturer of the fingerprint device; I have just taken a guess at how their device works based on some code they left behind.
If you wish to verify this, I have signed the checksum file inside there with my GPG signature, FA6FB12588810A870C92609D3901327190847975 Devyn Cairns <devyn.cairns@gmail.com> - so check that checksum file and then the signature with gpg.
Download and extract, then open a terminal wherever you put the AppImage file (right click, open a terminal in GNOME), then run:
sudo ./fprint-clear-storage-0.0.1-x86_64.AppImage
If goes well, it should tell you the name of the device and that it cleared it (along with some other libusb and udev related errors you can ignore)
If it doesn’t work, please post the log output.
