Upgrading Firmware via a USB Drive
HOW TO VERIFY YOUR MSPID AND FIRMWARE
USB drive information
- The preferred USB drive to use for the upgrade is the Sandisk Cruzer.
- The memory of the USB drive must be 16GB or less.
- We recommend backing up the Omni’s configuration before processing a firmware upgrade.
- When ready to upgrade the firmware, insert the USB drive into the USB port of the Omni controller.
Downloading Firmware
- The latest Omni firmware can be downloaded from: https://hayward.com/support/resources/firmware
- As of January 2024, only Omni controllers with firmware R4.8.0 and above can perform Over the Air (OTA) upgrades.
- Omni controllers with R4.7.0 or below installed, will require a USB drive to upgrade.
- Do not place the upgrade file into a folder on the USB drive.
- Ensure the upgrade file does not have a file extension added.
Preparing the Upgrade File
How to remove the .txt file extension from the upgrade file
- After downloading the firmware from Hayward’s website, check if a file extension was added.
- Any extension to the firmware upgrade file must be removed. Rename the file to remove the extension. ( See Below )
- This can be done before or after the file is loaded onto a USB drive.
- Select .txt and delete it.
- When ready, insert the USB drive with the upgrade file into the USB port of the Omni controller.
- Then later, will demonstrate how to back up the configuration and complete the upgrade from the Omni controller’s display.
