Firmware Update Methods

Method A: FTP / HTTP(S) URL (Manual via Device GUI)

  • Access your device’s Setup GUI → Support → Firmware Update.

  • Choose FTP/HTTP Update, enter the firmware URL (found on the NComputing Download page), and credentials if required.

  • Click Update. The device will download and install the firmware, rebooting upon completion.
    Temporary pause around 76% is normal—please wait until the reboot. NComputing+5NComputing+5NComputing+5

Method B: USB Stick (Manual via Device GUI)

  • Copy the .upd firmware file to a FAT32, NTFS, ext3, or ext4 USB stick’s root folder.

  • Insert into device, navigate to Support → Firmware Update → USB, refresh if needed.

  • Select firmware package and click Update. Device will reboot upon completion. NComputing+6NComputing+6NComputing+6

Method C: Remote Push via PMC

  • Log in to PMC Endpoint Manager → Administration → Files → Upload firmware image.

Best Practices & Considerations

  • Always backup device configuration before updating firmware.

  • Never power off or unplug the device during update—especially during the 76% pause.

  • Make sure the Device AMP license is current. Expired licenses block updates from PMC.

  • Use the official NComputing download links for firmware:
