Hi.

I have upgraded from 253T to 478T. Now I need to CP_OFF, bud cant use patch, that I have dowloaded. Cant use STD2 Toolbox, cant use Update-Approval_SOP4_signed. Still I get after "Parse error, invalid metainfo checksum". Why?

Thanks.

EDIT: Solved with this full reflash - 253T, 253T_CP_OFF, Toolbox for GEM 3.5 + swdownload patch, 478T, 478T_CP_OFF, Toolbox install.

Hi,

have next question :) I trying to activate SWaP/FEC, but without succes activation. CP_OFF work correctly, but SWaP/FEC no.

1) I try it with toolbox 8.3, GEM 4.11t and 4.3 too. Dump SWAP to SD, patch it on PC with SWaPPatcher.exe, then upload back from SD to unit with toolbox. Nothing changed. Same I try with FEC and signed_exception_list.txt.

2) I try it with patch for 478T, for first time with downloaded version, next time with patched swap.

Where can be problem? I have ODIS too, months ago i do it with ODIS, but now I cant connect to VAS from VMware via bluetooth, I have it on Windows 11 base system. So I trying it without ODIS.

Thanks!

EDIT: I have done it with ODIS, but if someone can answer, it can help to other users, maybe :)

    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

    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.
