Have a read of this it should give you a idea of what to do, ignore all mention of ViX 2.3 just substitute that with the latest ViX 2.4-155 image.
Flashing the Bootloader and Image
The receiver will come with a standard factory produced image ( The firmware or operating system for the receiver ) unless you have asked the retailer you purchased it from to load a specific image first, For the purposes of this tutorial i will assume this is the case and will be flashing the latest ViX 2.3 image with the Linux 3.1.1 kernel.
Before we get that far however you will need a few things.
1. A USB stick / key formatted the FAT32
2. The newest Vu+Duo bootloader ( duo_cfe_3_0_usb.zip )
3. The ViX image ( Current public version is ViX-2.3.204-vuduo_usb.zip )
4A. A little patience and some ones hand to hold if you have a nervous disposition.
4B. A clean pair of underpants ( just in case ).
To start we are going to first flash the Bootloader ( duo_cfe_3_0_usb.zip )
1. Power the receiver down by the power switch at the rear on the rear of the receiver.
2. unpack the bootloader file and place the folder ( vuplus and it's contents ) onto the USB stick. ( for this i use 7zip but winrar will do nicely. )
3. place the USB stick into any USB port on the receiver then power the receiver on by the power switch at the rear of the receiver.
WARNING NEVER remove the USB stick from the box while flashing either the bootloader or any image without first seeing the VFD prompt to do so and only then after powering the receiver down first.
Failure to do so could lead to a very expensive hardware failure, more commonly known as a "BRICK". As your expensive receiver is now effectively now only useful as a house brick.
you should now see a message on the VFD display of your Vu+ Duo that the USB stick is being read once this part is complete you will see a message telling you to remove the stick and reboot.
Power off the receiver then remove the USB stick, once again format the stick to FAT32. Now decompress the image file ( ViX-2.3.204-vuduo_usb.zip ) again placing the folder named vuplus and it's contents onto the stick and follow the same procedure as above for flashing the bootloader.
you should see the following displayed on the VFD one at a time during the flahing proccess.

Note that while the bootloader took only a few seconds to flash to your receiver, a full image flash will take a few minutes. Once this has completed and you see the VFD prompt you can again power down the receiver and remove the USB stick.
you can now power the box back on and allow it to boot, This process may take a few minutes but once complete you will be presented with a simple setup Wizard screen that will guide you through the various setup options helping you get started.
