    Hmmm I wonder if that part has been stored on the DM900uhd U206 MX25L25635F
    The dm520/525 has a similar serial flash memory chip, but then the 8p version 25L12835F

    My receiver was brick, because I installed original merlin image and not replaced drivers from /lib. I forgot and i restarted receiver. Only mode to rescue my receiver was installed bootloader from dreamboxupdate ( original bootloader from august/ september 2017). Now I have original bootloader and receiver running normal. But image is for sim 2.30.

    Hello from didier,
    I have a question about the service connector, is this acting like the db9 serial port from the dm800pvr.
    I suppose is a special cable? or simply acable gong to usb with a different connector like we use for photo downloading?
    regards didier

    This is my temporary solution. My new dreambox was reaching 69 degrees celsius. Removing the lid reduced the temperature to 58. Placing a pentium 4 heatsink on top of the original heatsink reduced the temperature to 49 degrees celsius.

    Good point. And how did you fit the radiator on the motherboard?

    I was just experimenting. The heatsink (radiator) is just sitting on top, not fitted yet. I was thinking about using a thermal pad to stick it on.

    The MAC address is inside the security chip (TPM), you need to replace the sim/TPM chip to change the MAC and Serial number of the box (For example to upgrade your box to a Japhar sim).
