[Download the rusEFI bundle](Download) for your hardware. 

## Windows:
Launch [rusEFI Console](Console). You can find it in the bundle you downloaded, in the "console" folder.

Click the "Update Firmware" button.

## Linux:
The canonical way to update the firmware on Linux is with DFU.

You will need dfu-util:
```
# Debian/Ubuntu
sudo apt install dfu-util
# Arch/Manjaro
sudo pacman -Syu dfu-util
```

Once you have dfu-util, you can run this from the extracted bundle directory:

```
java -jar console/rusefi_console.jar reboot_dfu

dfu-util -a 0 -D rusefi.dfu

```

## More Information

For more about DFU see [HOWTO-DFU](HOWTO-DFU)
