    Right now I have no reason to think that it could be a hardware failure, more thinking of that it may caused due corrupted data on the nand flash chip.
    Maybe because the nand chip has to many bad sectors, or just bad luck with some writings to it when it was in use.
    Other possibility is that it has been caused by uploading a image file, and interrupted while uploading.

    In any case, this seems to me that it can be fixed with Jtag the motherboard, erasing the nand flash chip, uploading a new Cfe bootloader file, and uploading a new image file on the normal way.

    Other option could be to replace the nand flash chip for a new pre-programmed chip.

    Right now I could not offer you a tutorial howto jtag the solo2 but when you read this topic then you can see the cypress jtag board you need and the jtag pins etc.
    As for the cfe file, this is easy to find on the internet, or else see the Vu-HD site. the vusolo2-flash by jtag file.

    Because you have a original, it can maybe it can be fixed with a serial tool, but I have mo nowlidge of it.
    The only way it should be done is by using the cypress CY7c68013a board which is cheap to find on sites as ebay.
    As for files and bbs software, this I can give you tomorrow later on the day.

    About the Jtag Solo2 original...

    Hardware/software needed..
    1. Vu+ Solo2 receiver for the connection to the P701 connector.
    2. CY7C68013A development board.
    3. Broadband Studio 3 software with the the bcm97346 cpu drivers.
    4. CFE bin file.
    5. And (of course) a windows computer etc.

    First install the,
    1. Broadband Studio 3 software.
    2. Then connect the development board with the usb cable, turn it on, driver install will follow.

    It will do this driver installation twice.

    3. Switch off the development board, Connect the Gnd/Sda/Scl wires to the P701 connector.
    Mb P701: Scl -> Cyb. Scl
    Mb P701: Sda -> Cyb. Sda
    Mb P701: Gnd -> Cyb. Gnd

    Howto connect step 4.
    4A. Start up the Broadband Studio 3 software,
    4B. Choose the Bcm97346,
    4C. Turn On the receiver,
    4D. Switch on the development board.

    Or when it not connecting,

    4A. Switch on the development board,
    4B. Turn On the receiver,
    4C. Start up the Broadband Studio 3 software,
    4D. Choose the Bcm97346.

    And when all is correct, you should see the connection to the Bcm97346 cpu but when not, switch Off the motherboard, and turn it On again.
    After this you must see a connection, if not, then you have not a good working motherboard or development board or some other cause.

    5. Choose Flash explorer, choose Samsung K9F1G08UOA, press Refresh, Browse to the Cfe file and press Start.

    When finished, disconnect the development board and upload a image file on the regular way by Usb.

    Download...
    The Broadband Studio 3 software with the the bcm97346 cpu drivers and pdf instructions can be downloaded from mega.nz, file is 84.3Mb.

    An Cfe bin file can be downloaded from beneath, it's for the original, but can also used with clones because I've tested it on a solo2 clone with a new nand flash chip.
    And also included the Usb drivers download, normally it should be already installed after the installation of the Bbs software, but just in case you needed.
