This OontZ Angle 3XL firmware update is of benefit when you are using an Apple Bluetooth source: iPhone; iPad; MacBook Pro, MacBook Air, iMac systems.
The firmware version 1.4 enables the OontZ Angle 3XL to playback audio with more control over the volume levels offering a lower minimum volume and more volume level options up to maximum volume. The update is not needed for playing from non-Apple Source devices as the as the lower minimum volume level and the increased control over volume levels is already supported on all Non-Apple Source Devices
Before starting please have ready your 3.5mm audio cable and USB Thumb Drive (The USB Thumb Drive must be 8Gb capacity or smaller capacity).
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 A : Download the firmware ZIP file named 'system.zip' to your hard drive using the following link (Right-click and select "Save Link As..." to save ): system.zip
Step B : The file 'system.zip' must be unzipped before copying the contents to the USB Thumb Drive. To unzip the file on a Mac, double-click it. To open the file on a PC, drag it to the desktop. Once the file is on the desktop, you can double-click to open the zipped file to see its contents. It contains a folder named 'system' within it which you will copy to your USB Thumb drive. Do not copy 'system.zip' to the drive.
Step C: Drag and drop the folder 'system' to your USB Thumb drive. The 'system' folder contains 2 files named "upgrade_XL.bin" and "upgrade.txt".

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
