Thread: Garmin Nüvi 2567 Thai unit software

In explanation of the message 'System Software Missing' which is encountered when a unit software update is not completed. It can happen in 2 ways: Firstly [and commonly] an interrupted 'normal' firmware update [where the unit loses power or loses it's data connection to PC or an online update is cancelled midway or an internet outage occurs] resulting in the current firmware, aka system software, being erased but the updated firmware not being completely installed. The second way it occurs is during a conversion or 'cross-flash' where it's desired to retain the HWID but an 'inappropriate' boot.bin is used and there's simply not the capability to load the new firmware. In either case loading the complete original firmware to the unit will usually successfully fix it because the HWID has been retained and the bootloader was unchanged.

The 2nd scenario is what you faced using the US boot.bin, and the unit was not successfully loading the Asian firmware but that problem is normally quite easily reversible as you've found.

When you said this:

............. and with the file provided in the package.

do you mean that you tried to load the full Asian firmware with Updater.exe [gupdate.gcd first converted to *.rgn file using RGN_Tool]? Or did you simply try to load it by using the Asian launcher.exe tool? The second method will only work if your unit already has a correct Asian HWID of course.

The flashing of complete Asian firmware with Updater.exe has a much better chance of working because it has the correct boot bin to load the fw, but it will change the HWID to Asian and also has a much higher chance of 'bricking' the unit. The chance of bricking is lessened by the matching PCB P/Ns however. If you haven't tried that but don't wish to do so because of the higher bricking risk that's completely understandable of course and i'm not trying to encourage you to do so, simply because i don't have a HWID 1582 device to try it first.

Perhaps if some member has already tried a full Asian flash in US/EU HWID 1582 2xx7 they'll post here to report the results.
