    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"

    why don't you just download and try!!
    ocflash will downgrade 1.xx to 1.39 (included firmware) except if interface's pic was erased

    Hello everyone,
    I am new on here and looking to get some help on my OP-com device. I just have purchased a device where the firmware version is V1.70 (able to be upgraded and downgraded) and needing some help as I have flashed to V1.59 but now wish to flash it back to V1.70.
    Since at the "Firmwarefiles" folder the higher version is 1.59, how can I get the 1.70 version back on my device ?
    Any help would be much appreciated
