DM520 will not boot!

  • Good evening
    Help!!
    After an update to my DM520, it never started again!
    I've tried flashing again, but I can not!
    Any way to flash with DreamUp? If so, can someone tell me how to do it !?
    greetings

  • DreamUp will not work with the newer boxes.


    Which kind of update did you do? Did you flash an image? Maybe one of another Box? Then the Rescue Loader might be destroyed and you need to flash via the service port.


    But let's hope for a simple solution first :grinning_squinting_face:
    Can you access the rescue loader?
    Please do so by shutting down the box and switching off power with the rear switch. Then turn it on again and wait a little less than 1 second. Within that second the touch sensor at the front should turn red. Press it as soon as it turns red.
    When the LED starts to flash in blue and red, keep the finger on the sensor. If the sensor turns red again, you can lift your finger :)


    If this still doesn't help, you should provide a bootlog via the service port.

  • Thanks for the answer!
    The update was made online and the image was OpenAtv, after updating I rebooted but never started again!
    As for the procedure that you refer, I have tried but the led is always red, there is no flashing between red and blue!
    I do not know how to recover otherwise!
    greetings


    PS:If this still doesn't help, you should provide a bootlog via the service port.
    What do you mean by that?

  • Well I mean, that it is now the time to create a bootlog :)


    What you need:
    1. Mini-USB cable (the "old one", not a Micro USB)
    2. Install the VSCP driver from https://dreambox.de/en/downloads (you can use the ones of the 800se or 500HD, they're all the same) on your PC
    3. Connect the service port to your PC with the MiniUSB cable
    4. Install PuTTY (http://www.chiark.greenend.org…atham/putty/download.html) and specifiy the settings accordingly:
    "Connection type": Serial
    "Speed": 115200
    "Serial line": the correct com port as you can find it in the Windows device manager (i.e. COM1 or COM2 etc...)
    Session -> Logging: Select "All session output" and under "Log file name" browse for a folder and file name to write the log to. e.g. Desktop and file bootlog.log :)
    5. Press "Open"


    Then turn on the box and watch the log. If the outputs in the log stop to change or repeat, you can stop the log by closing PuTTY. Then you might upload the log here, so we can have a look at it :)

  • According to the log the box boots fine vor the first 3 seconds and then gets stuck with starting the Linux.


    I have no idea what happens there. But as the boot starts off completely fine on the lower levels, you should definitely be able to enter the rescue loader.


    You might try to stop the box by pressing a key in the serial console (PuTTY) as soon as that text appears:

    Code
    Not interrupted yet, trying autoboot or rescue loader, hit any key in the next 500ms to cancel
    Proceeding with autoboot.. You can try aborting with Ctrl+C


    So try pressing a button within that 0.5 seconds or pressing Ctrl + C.

  • Ok. Now you've stopped the boot process. It says that it received an IP: 192.168.0.219
    Can you access the box from PC via a Browser or Telnet?

  • One last idea to get to the rescue loader the normal way: Have you really waited to press the soft button until the second the red led lights up? You might try a little variation of the timing.



    If that doesn't help, you might want to try the method mentioned at: https://dreambox.de/board/inde…&postID=156617#post156617


    Please exchange the file names accordingly (you need http://dreamboxupdate.com/open…4-r0.3-dm520-20160820.bin as a rescue loader)

  • No communication means what? Are you able to enter anything via the serial console when the CFE> appears?


    But as I said: Only your OpenATV image is broken. You should still be able to enter the rescue loader without any problems. But the process needs the correct timing!
    So, are you 100% sure, that you start pressing the front button in the exact moment that the red led lights up? You must not be too fast and not too slow.

  • Sounds rather tricky :grinning_squinting_face: Congratulations :hurra:


    Maybe someone else nows how to get there via the serial console like DreamUP did it for the old boxes.

    Great!! I have solved with this tric ...and my 525 combo blocked on red led fix, after flashing OpenATV image.
    Touching the front button at the right moment the decoder went back to rescue mode. Thank you

  • hello,
    I had exactly the same problem as our friend Barbo2 with ATV image and update.
    I did the same procedure describe by excellent friend M0rphU and after several attempts I was able to find my box
    Thank you again for your valuable advice, my friends.
    Best regards

  • Hi. I have a similar problem, my box is looping and is not restarting. If I could acess file system I will erase one file I copied. How can I do that?
