OX Amp Top Box firmware can be updated to improve performance and/or add new features. This article contains complete details about OX firmware.
The current OX firmware is v1.2. The OX Amp Top Box app and OX’s firmware both need updates to use v1.2 features. Updating firmware does not affect user presets.
Note: As of March 26, 2025, the OX Amp Top Box software apps require a service update. Please update now by downloading the latest apps here to ensure you continue to have access to your software.
How To Install OX Firmware v1.2
First, you’ll create a firmware updater on a specially formatted USB drive on a Mac or Windows computer. Then, you’ll plug the USB drive into OX to update its firmware.
To prepare the USB update image, you need:
- USB flash drive (1 GB or larger capacity)
- Mac or Windows computer
Create your USB drive firmware updater on Mac or Windows computer
Important: Creating the USB drive firmware updater permanently erases all existing content on the USB drive.
- Click the button to download the OX-v1.2.0-Firmware.img.gz firmware binary image file.
- Download, install, and launch balenaEtcher, a free flash drive image utility.
- In balenaEtcher, click the “Select Image” button then choose the downloaded binary image file (or drag the firmware binary image file onto the balenaEtcher window).
- Connect the USB drive (it will be erased), confirm the drive selection in balenaEtcher, then click the “Flash!” button.
- After flashing is complete, follow the OX firmware update instructions below.
Update the firmware on your OX Amp Top Box
Note: Before proceeding, create the USB drive firmware updater using the steps above.
- Power off OX.
- Insert the USB drive firmware updater into either USB-A port on OX's rear panel.
- Press and hold the RESET button on OX's rear panel while powering on OX.
- Continue holding the RESET button until the front panel RIG LED starts blinking.
- Release the RESET button. After about two minutes, OX restarts automatically.
- After the RIG LED stops blinking, remove the USB drive and OX is ready for use.

USB Firmware Update Notes
- If creating the USB drive firmware updater is unsuccessful, try a different USB drive.
- OX may not recognize all USB drives, even if the firmware updater was successfully created. If the RIG LED remains solid red and never blinks when following the update instructions, recreate another firmware updater on a different USB drive, and follow the update instructions again.
