    Hello,
    i got a dreambox 800 hd se with sim 2.10. Last week it won't start up. So i flashed a new image. But it gets every time in to flash ip mode. After flashing with recover bad sectors i get a report of many bad sectors. I think that the nand flash chip has to be replaced. But can anyone help me with this?

    Could be the nand flash chip or other cause related to the chip as a outdated solder or other cause as one of the 8 data lines from/to the nand flash chip to the cpu.

    If you have the skills and right tools as a hot air station and kapton tape then it is not so difficult to replace it.
    Just protect the surrounding area with the kapton tape, heat up the nand flash chip and remove it.
    Do not remove the solder from the nand flash chip on the motherboard, just place the new one on the old solder.

    All other methods as with a solder iron and the use of solder wick can also, but there is more risk of damaging the solder legs of the motherboard, better is to use also smd chipquick paste.

    But if you have not the knowledge and tools then it's better to let it repaired by someone with these skills.
