Audikast 4HA - Rename and Passcode Guide

Once the update is complete, you can change the broadcast name and passcode and adjust the default volume settings.

Quick Check

● Download and open the DFU tool on your computer

● Use a USB data cable (not charge-only)

● Plug Audikast directly into your computer (Windows/Mac)

● Make sure Audikast is powered ON

● Load the firmware file → click Run / Start

● If nothing happens, try a different USB port or cable

 Once the firmware is completed, go to Settings, then select the broadcast name and encryption options.

Common Reasons the DFU Update Fails

● Using a charge-only cable (no data transfer)

● DFU tool not installed correctly on the computer

● Device not detected by the computer

● Wrong firmware file selected

● USB port or cable is unstable

💡 Tip:

If the tool does not detect the device: Try another USB cable — many cables that come with chargers cannot transfer data.

Still not working?

● Restart your computer and try again

● Try a different computer (important test)
