    Flash the box with the frontpanel method, pressing the frontpanel button that is read (press mostly immediately after you turn on the box) and keep the finger on the button until it finishes flasing red-blue, as it happens on the DM520HD. You could have to try few times, but try again and again until you get that button flashing red-blue and keep until it stops flashing.

    Then you will be in the Rescue Mode and will have an IP address on your TV,

    And flash our image below and let me know if it works,

    Then let me know how it goes with our DM900UHD OpenPLi 6++ image ;o)

    Finaly I succeeded.
    I put on usb stick rescue-dm900.bin (from here - https://board.newnigma2.to/wbb4/ind...20-525-DM820-DM900-DM920-DM7080-USB-Recovery/) ; boot rescue-dm900.bin then receiver go to the rescue and I could to install new image. I installed old backup was made few days ago. After that I wanted to try OpenPLI 6++ Japhar for Sim 2.30, but I can't to the rescue mode. I tryed from telnet (to-the-rescue), with remote control from menu and start receiver with press red button. Nothing. I can't to the rescue mode. Very strange.

    For the IP address, it's normal you have problems, most probably your Router/Modem is 1 Gbps, and to get an IP address with the 2.30 clones you need a 100 Mbps Router/Modem, so an old one (don't need to be connected to internet, as you need just IP and network to connect to flash box).

    Did you ever successfully flashed my image OpenPLi 6++ Sim 2.30, MEGA link I gave you ? As I don't have DM900UHD boxes, would like to know if that image works. Thanks.

    Be careful that using the FrontPanel Red button is not working every time, as for DM520HD it could be difficult but you need to try again and again, to have it successfully switching to Rescue Mode (Press the Red button once turn on the box, not too early but not too late, then keep pressed your finger on that red button and keep it flashing red-blue until it stops and stays red. It will then show on the TV the IP Address of box in Rescue Bootloader mode).

    I use all methods; with finger and from putty - to-the-rescue and echo "rescue" >> /proc/stb/fp/boot_mode && reboot
    Receiver not in recovery mode. He does not want at all.
    Your image I installed; it's ok. Has few bugs, but nothing important.

    Only if your receiver dont go in recovery mode

    For rescue DM900 use usb cable and putty (serial port).

    Start receiver and push ctrl+C to enter in cfe mode. Use usb stick for rescue file downloaded from internet.
    ifconfig eth0 -auto
    show devices
    dir usbdisk0
    boot usbdisk0:zImage-rescue-xxxxx

    Then your receiver get in rescue mode and you can flash firmware.

    Thanks toysoft and johny for help.

    P.S. - toysoft - yourOpenpli image work on dm900 sim 2.30 - https://mega.nz/#!ZjgFEa5Y!yuMmAj4kLGjxvIKPn372EcNzLm0Z7wY6EUvaWLIWmhw . I have not tested too much time. Can put this link on another site? Thanks again.

    @toysoft - take a look at pictures

    I have original bootloader from dreamboxupdate - zImage-rescue-3.14-r0-dm900-20170801.bin

    I think there was no clone bootloader because the original one can be used. Otherwise I think it had already appeared.

    If you load the original Bootloader, you box will be stuck/bricked for ever. You will have to send to manufacturer to fix. The bootloader/rescue checks the sim card and if it's not OK, the box is not booting. If you change it and the sim inside the box is not correct even the bootloader/rescue will not start, and you will have bricked your box.
