    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.
    Jinzhanhua, how did u convert oregon 450/550 US to CHNversion??

    Hi Alex, I could not find the CHN firmware, however I can find TWN firmware.

    [Only registered and activated users can see links. ]

    I just want to change my oregon to chinese version. Let me know if you found anything. Thanks!
