I have US Oregon 550 which I tried to patch its firmware with Korean firmware and bricked it.
1. Bricked US Oregon 550 HWID 0896 S/W ver 660
2. I followed RGN_tools to change US to Korean. But Its instruction gave me "software missing error" and didn't work.
So I changed both boot.bin and fw_all.bin to Korean HWID 1209 sw 280.
3. Device now just boots into the software missing error then red screen, no filesyetem access to internl memory
4. No, PC does not see the device anymore
5. Downloaded GCD files from garmin download, Oregon550,Korea_GCDfile__280.gcd and Oregonx50_WebUpdater__660.gcd
Ran GarminCure and created cure file with ver 660
Applied using updater and updater gave me an error "invalid device"
The device is NOT detected by the PC. Garmin Webupdater see the device as Korean 550 and gives me errors
6. Yes, Garmin driver's are installed (as part of Garmin express)
7. HWID is 1209 (changed by boot.bin patch, original is 0896)
8. Yes, tried that (Pl. see #5 above)
9. Yes, In preboot mode I can see System (and loading when applying the update using Updater). The screen is turn off with updater saying invalid device
(my guess is cured firmware of US doens't match with current HWID 1209. Is there anyway to change HWID back to original??
10. Sorry No, my bad, No NV backup
11. Waiting for your response. If I can change HWID 1209(korean 550) back to original 0896(US 550), I guess cure and updater can work.
Is there anyway to change HWID 1209 back to original 0869??
Thank you in advance.
