- [Latest Update](https://fwupd.org/lvfs/devices/work.frame.Laptop.Ryzen7040.BIOS.firmware)
## Getting the fingerprint sensor to work
The firmware on the fingerprint sensor needs a downgrade to make it work on Linux.
The process is documented [here](https://knowledgebase.frame.work/en_us/updating-fingerprint-reader-firmware-on-linux-for-13th-gen-and-amd-ryzen-7040-series-laptops-HJrvxv_za).
However on recent NixOS versions also fwupd can no longer update the firmware.
Using the following snippet allows to temporarly downgrade fwupd to an old-enough version:
```nix
{
services.fwupd.enable = true;
# we need fwupd 1.9.7 to downgrade the fingerprint sensor firmware
services.fwupd.package = (import (builtins.fetchTarball {
url = "https://github.com/NixOS/nixpkgs/archive/bb2009ca185d97813e75736c2b8d1d8bb81bde05.tar.gz";
sha256 = "sha256:003qcrsq5g5lggfrpq31gcvj82lb065xvr7bpfa8ddsw8x4dnysk";
}) {
inherit (pkgs) system;
}).fwupd;
}
```
Afterwards the downgraded driver can be downloaded and installed like this:
```
wget https://github.com/FrameworkComputer/linux-docs/raw/main/goodix-moc-609c-v01000330.cab
sudo fwupdtool install --allow-reinstall --allow-older goodix-moc-609c-v01000330.cab

```
The error message above is harmless. After a reboot, I was able to enroll my fingerprint like this:
```
sudo fprintd-enroll $USER
```
