    Flashing a new firmware (image) by Browser

    What you need to flash
    You need the image file you want to flash. Image files have the extension *.nfi. You can't flash other
    images like *.img files. Don't try it - it won't work.
    You need either a DHCP server, a configured bootloader or a serial cable and a terminal program
    like HyperTerm.
    You need a browser, and a network cable. If you connect the Dreambox directly to the PC,
    you need a cross cable, if you connect trough a switch/hub/router you need a normal
    (non-cross) cable.
    To flash a new image, you can use the second stage loader. It must be present and not broken.
    The following steps assume you have a DHCP server. If you don't have one, you have to setup
    an IP address in the bootloader's serial setup.



    - Power down the Dreambox, either using "shutdown" and by removing the power connector.

    Standby is not enough!



    - (1.) Press and hold the power button. Replug the power connector into the Dreambox.
    - (3.) A text "*** STOP ***" should appear. Now you can release the button.
    The bootloader entered the "waiting" mode.
    - (4.) Above the "*** STOP ***" text, there should appear an IP-address
    (four decimal values with a dot in between). If there appears the string "dhcp" instead,
    the box still searches for a DHCP server. Wait a bit. If it doesn't change, something doesn't
    work with the DHCP server. Check wether network cable is plugged in etc. If it just doesn't
    work, set an IP using the serial terminal)



    * - Now, open a browser on your PC.
    (1.) enter in the address line "http://ip/" (where ip must be replaced with the value in the LCD).
    - (2.) on the bottom of the page, there's a link called "firmware upgrade". Click it.



    * - On the next page, you can select the flash image you want to flash. be sure that it has the ".nfi" extension.
    You can't flash other images (like .img)!
    - Click on "FLASH!" and wait. It might take some time to upload and flash the image.
    - Switch the box off again, and on again. The new image should be flashed and working.
