Flashing Firmware from a USB Flash Drive

Flashing Firmware from a USB Flash Drive

This article covers flashing, or installing, firmware onto your System76 computer using a USB flash drive. These instructions are written for firmware files provided directly by System76. If you are experiencing behavior on your System76 computer that you believe is due to the firmware you are using, please contact System76 support.

Things that you will need

  • Firmware file from System76
  • 1-2 flash drives (1GB and up)
  • Philips Screwdriver
  • Approx. 30 mins.

Format the USB Drive

The USB drive used to flash the firmware, must be formatted to the FAT32 filesystem. If you need to reformat your flash drive as FAT32, please refer to our Format Your Drive support article.

Unzipping the Files

Depending on the decompression method you're using, you may need to perform an additional step. In some cases, the unzipped file is moved into a folder with the same name. For example, "" becomes a directory called "oryx6-76ec" instead.

The mainboard will not know how to access the files inside the directory. The firmware flashing will not work in this case. Instead, move the files outside of the parent directory, delete the parent directory, and try booting again.

Pop!_OS extracts the files correctly by default (see screenshots below), but other extraction tools or other operating systems such as macOS may behave differently.



The highlighted files pictured below (the hash will change based on file and model) are the two items that should be in the root of the USB drive.


Booting the USB Firmware Updater

After the flash drive is ready, power off your system. Then, power back on your system and tap the ESC key while the system is turning on. This will take you to the firmware boot menu, where you should select the USB flash drive from the list of boot options. To select the USB drive, you will use the Arrow keys to change the highlighted line, then press the ENTER key to select it.

If you are unable to access the firmware boot menu by pressing the ESC key while powering on the system, then shutdown the computer and remove the drives from the system. You can find instructions for removing the drives from your system on the tech-docs webpage.

Once the firmware is updated, we may need to boot with a live image in order to repair the boot loader if you dual-boot with Windows 10. We provide step by step instructions on how to do this in our support articles in the links below:

If at any point you run into any errors during this process please paste / attach photos of the errors in a support ticket.
