Updating your OontZ Angle 3XL to firmware version 2.4

To complete the firmware update you will need the USB Thumb Drive that we sent you.   You will also need the 3.5mm audio cable that came with your speaker.

Important Note: If your OontZ Angle 3XL is paired to a second OontZ Angle 3XL speaker via OontZ Wireless Dual Pairing, you will need to unpair them before proceeding with the firmware update. Click here for unpairing instructions

Step 1 :
Power on the OontZ Angle 3XL by pressing and releasing the On/Off Button

Step 2 : Open the Connector Flap on the rear of your OontZ Angle 3XL

Step 3 : With your AUX IN 3.5mm audio cable not connected to any other device, insert one end into the AUX IN Jack (figure 3-a), the Bluetooth Indicator Light will turn green (figure 3-b) and you will hear the voice prompt: “AUX IN Source”.

Step 4 : Insert the USB drive into the USB Power Bank connector.  The USB drive should remain inserted until the firmware update process is complete.

Step 5 : Press and Hold the Next Track button for 5 seconds (figure 5-a).
The Red, Blue, and White lights will light up solid and remain on for about 30 seconds (figure 5-b)
Important: Please watch the three lights as the 30 second time approaches to confirm the following sequence (see animation in Figure 5-c below):
All three lights will flash together 7 times, then only the Red light will flash once, then the Green light turns on and remains solid as you hear the voice prompt: “AUX IN Source”. If the lights don't match this sequence then the firmware did not update successfully and you will have to repeat the update process
