Thread: Patched firmwares for JNX files

After the important observations of AlexWhiter and Giomen, I decided remake the procedure on my Oregon 450 with more attention. Some unusual things happened, it remains to investigate the cause, but the end result is that the symptom of older software warning appears when doing the upgrade from fw 5.90 patched to 6.00 patched, see the result, in some curious passages:


1. Downgrade of the Fw 6.00 Patched to original Fw 5.90 - Result: ok, normal warning of older software

2. Upgrade of original FW 5.90 to Fw 6.00 Patched - Result: ok, and without warning

3. Downgrade of Fw 6.00 Patched to Fw 5.90 patched - Result: ok, but curiously without any warning of older software

4. Upgrade of Fw 5.90 patched to Fw 6.00 patched - Result: ok, but curiously with warning of older software being installed ("Found new software. The software is older than the current one. Intends to continue the installation and delete your user data?" YES x NO) and gps go to factory default: language, measurement units, satellite position.. (software installed: Patched Version 6.00)


Finally, I hope that my observations not have been taken as criticism, far from it, were mere findings. By the way, some unimportant to me. The end result is that you can use files JNX, is what matters. So I am, like many thousands of other users of Garmin handhelds, most grateful to AlexWhiter, a great guy: thanks for sharing the result of your important work. We owe a lot to people like you!
