Section 1: Firmware update

To update the HoloWHAS firmware, you will need a USB drive.

Follow the step-by-step instructions:

For example, update HoloWHAS-Ultra-GC firmware.

1\ Download the firmware from the Google Drive link:

https://drive.google.com/file/d/1z5bqiM0XzPV4s-oXT-FYmKaxz3Zfwp2I/view?usp=sharing

The firmware is a single file named update-holowhas-ultra-gc-1.6.12.zt

2\ Format your USB drive using the exFAT file system.

3\ Copy the firmware file into the USB drive. Ensure there is only one firmware file on the USB drive.

4\ Plug the USB drive into the device’s USB port. After a few seconds, the STATUS LED on the front panel will start blinking white-green. Do not turn off the device during this process.

5\ Wait until the LED turns solid white, indicating the firmware update is complete.

6\ Remove the USB drive from the device.

7\ Close the HoloHome app completely, then relaunch it. Verify the firmware version by navigating through the HoloHome app UI:

Go to the “Equipment” tab → “Config” → “Device Info” → “Firmware Version.” Confirm the version is 1.6.12.
