    Unhappy How to Convert Oregon 450us firmware to CHN? I have Oregon 450 CHN V2.2 GCD/RGN

    dear all,I have got the Oregon 450 from us,the HWID:896, SW Version:4.50
    and I have got the firmware of CHN Oregon 450, HWID:1276, SW Version:2.20

    I have:Oregon 450 us firmware v4.5, Oregon 450 CHN firmware v2.2, the tools of updater.exe & RGN_Tool_V074, UltraEdit

    I have failed repeatedly for convert.

    I use RGN_TOOL & updater.exe to convert us firmware to CHN, than display system software missing...
    so I use updater to us firmware,the Oregon 450 is ok.


    the file : B1276000C_main.bin 31.8MB, how can I use the file. I wonder if the document related to the chinese input.
    the file: B1276000C_sys.bin 11.9MB, How can I use the file
    the file: checksum.txt ,content is
    ------------------------
    Programmed Device Part Number: 541-B1276-00
    Fill Ram Value: FF

    Programmed NAND Checksum (for 13 MB)

    I am a little late in other requests, but maybe the software missing is due to other HWID and SW Version not replaced by RGN_Tool. I have yet to work on this issue that happens for some GPS model. You can try to make a manual search and replace with a Hex Editor. RGN_Tool will likely miss one or 2 instances. I think it is in the boot.bin section, but check also fw_all.bin to be sure.

    Same problem here. I am trying to convert my StreetPilot c550 to Mercedes or Mopar version. Unfortunately the SP always displays "System Software Missing":

    Hope Turbo or someone else figure out how this could be fixed.

    Not the HWID and SW version's problem, Garmin added another checker inside firmware.
    I think the checker inside all non-english model.
    I am checking TWN firmware, need a little time.
    The problem is:
    After run english firmware on non-english model, the non-english model will report software missing too.
    Only run! not flash english firmware to non-english model!
    I can convert OREGON 450&550 USA to CHN version, the newest CHN version is 2.30.
    I think pureblue got factory firmware from garmin.
    These filename is like as map of NAND chip.
    BTW:
    Thanks turboccc, I use your GIR_Editor to modify startup logo of OREGON.
