Hi All, I just tried updating from MST2_EU_VW_PQ_P0359T to MST2_EU_VW_PQ_P0478T and the unit got stuck at the VW logo on restart and will not boot. Does anyone know of a fix? Thanks

Hi,

EDIT: Solved, must by shorted 2 contacts on board to enter emergency mode on tachnisat too.

Thank you, brother! I am a unit with nav
Is there an easier way?
(hint: the unit is not ready, the software update is not ready. Please wait a moment. It may take 10 minutes).

I have MST2_EU_VW_P0478T
3Q0035842C
H41

I have 1 SD slot
I do NOT have NAV

I need help to unlock all FEC codes.

I am a member of the motorcarsoft.com forum, and I downloaded their patch and guides, but they are too complicated for me and I need to know if the unit can be patched remotely without disassembling.

Also is the UART connection required?

I have OBDeleven pro

PM contacts are welcome

Thanks for the information, there is a lot of information but there is no manual that explains it step by step, for newbies like me.
If someone can explain it in steps I would be grateful
eg the exact connections from the SD to the motherboard, if using RNS Uart ...
my MIB STD2 ZR + NAV continually restarts with the skoda logo due to a bad update.
help please :cry:

EDIT:
I deduce the following:
you have to put the SD card in slot 1 with the FW,
connect the UART (I have doubt if you have to connect the GND or not )
then open the PUTTY on the PC
and finally join the 2 points on the base plate.
is this correct ?
Which image shows the correct connection 1 or 2?
I am VERY new too, What unit do you have? I was hoping that with the UART and Discover Mediam you can avoid messing around with the PINS

Is the only problem for updating from 01xx to 02xx that the emmc is too small? Or is the ram also to small?

What is the size different between a emmc from a 01xx unit to a 02xx? I saw in one of the first post, that the emmc is a MTFC8GLWDQ-3M AIT Z. Is it from a 02xx (or higher) unit? (That should be a 64gb)

Hi, is there any big repository that contains different software versions from different regions? I'm looking specifically for Delphi software/firmware as I need it to be able to mess about with my NAR car that I have imported to Europe. Thanks!

    Device: Technisat MIB STD2 PQ nav

    This device does not have serial shell .
    But I successfully hacked the emmc filesystem
    Now serial port has a shell

    Step1.
    Desolder the EMMC chip

    Step2.
    Dump EMMC chip via SD card reader

    Step3.
    qemu-img convert -f raw d:\682C_EMMC_DUMP.bin -O vmdk d:\682c.vmdk

    Step4.
    Start QNX x86 vmware machine to modify the 682c.vmdk

    Step5.
    modify the file /fs/hd1-qnx6/tsd/bin/system/startup
    add following line
    --------------------
    echo ser1 "/bin/login -f root" qansi-m on > /tmp/ttys
    /sbin/tinit -f /tmp/ttys &
    --------------------
    Save the file

    Step6.
    Shutdown QNX6 VM

    Step7.
    qemu-img convert -f vmdk d:\682c.vmdk -O raw C:\682C_EMMC_DUMP.bin

    Step8.
    write C:\682C_EMMC_DUMP.bin to EMMC via SD card reader

    Step9.
    Solder the EMMC chip back

    done.
    ;)

    Привет, ребята, есть шанс, что кто-то снова сможет поделиться этими материалами, потому что ссылки выше не работают. Думаю, многие из нас это оценили бы.

    Заранее спасибо.
