Preparation.
1. Format a USB stick to FAT32 using tool found in this download

2. Download the image of your choice and extract it to your desktop.
3. Open the folder you extracted to your desktop,you will see another folder named vuplus, this is your image file. Copy the
entire vuplus folder directly to the USB stick.
Flashing the Receiver.
Fully power the receiver down via the rocker switch at the rear of the receiver.
Make sure no USB devices are plugged into the receiver at this point.
Insert the USB stick containing the image files into one of the USB ports on the receiver.
Power the receiver on from the rear rocker switch and await instructions.As your Solo2 starts to power up you should see a prompt on the receivers display asking you to
press the power button, at this point you need to press the power button on the front of the receiver,
( the blue circles to the left of the front panel, this is a touch sensitive button ).
If you dont see the prompt to press the power button but instead see the message “starting” it means
that the receiver has not detected the USB stick or image files or both. If this happens start from the
beginning or try another USB stick, Image or USB port on the receiver.
If all goes well the flashing process should take approximately 2 minutes to complete
