    here I send a flash bin MX29LV320, I hope it serves you, in any case, the emmc memory could be replaced by a card SD.

    Hello, you can use the booticex86 application, select the partition, activate it and it will show active partition at that moment, so with all partitions, greetings.

    i get the radio. Thx for the dumps

    finally i understand this

    there is two different storage in the radio:

    -MX29LV320ET
    -some kind emmc (doesn't matter the type)

    the mx storing the basic opsystem like the PC bios
    and the eemc stroing the maps..etc it's working like a hdd

    If you stuck on the logo:
    - Probably the emmc is dead. You can change to any type of emmc with the same package (BGA169). But before put in you have to create partitions, or you can change to a regular SD card BUT it's really slow stuff. Be careful with the removing bcose the eemc is glued to the pcb. (easy to losing some pins)
    - Or maybe the rams are dead. It's made from really cheap low cost stuffs

    Totally blank screen:

    - Bad MX flash
    - Bad update

    you can fix the corrupt flash thru the jtag port or with a proper programmer (hot air, removing, tsop48 socket..etc)


    In my case the owner didn't finish the update process and the MX is totally empty. Now my beeprog working on it

    thx

    with neutec dump not working at all. Probably bcose it's wr3 dump not wr1 (only 4 bytes diff)
    with attilaa0 dump switched on but stuck on the dacia logo, after 3-4 sec on the screen appearing some withe dots blue shaking screen and dead. I think the emmc file system corrupted too.
    i will working on the eemc soon
