    Default OCflash Downgrade OPCOM firmware if was upgraded from 2011 2012 official software

    i found a program that is supposed to be able to downgrade opcom firmware to 1.39 EVEN if it was upgraded to 1.41 or 1.43 or 1.44 or 1.45 by means of 2011 2012 official opcom software

    no matter if you started some 2011 2012 official opcom version with interface plugged in computer, which would have upgraded to 1.43 or 1.44 but disabling bootloader

    2011 and 2012 official software versions of opcom dont erase pic of interface but disable bootloader

    ocflash doesnt work if you started some 2010 version with interface plugged in computer, which erased your interface's pic

    howto:

    1. connect opcom interface through usb only
    2. run ocflash
    3. click on "request interface" to check actual version programmed on interface
    4. if programmed version is 1.44 or 1.45 click "load firmware" and select fw139.hex from "Firmwarefiles" folder
    5. click "change"
    6. select "automatic mode" and click "flash"

    ocflash will downgrade 1.xx to 1.39 (included firmware) except if interface's pic was erased

    Thanks for the software, successfully downgraded but now not sure if the 1.39 will work well with VauxCom 120309a. Was having firmware v1.41 and it's failing to program new ecu for Astra H and had advise to downgrade.
