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.

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

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

Have you tried deleting region 34 after uploading the firmware? (make backup before of course)

BTW thanks for the link.

Hi ddabcd277, i am no expert in computer programming. So i m not sure what deleting region 34 means. Can you explain further in more details?

Anyone with any idea for changing the oregon US unit to CHN or TWN firmware?
