Keep gupdate.gcd on-board after update?

[osiris4isis]

That's true, asking is easiest route. Thanks for the excellent answer, the list is a "gold mine" of info !! Is Perry site the only "backup" site with Garmin's firmwares? Is there a way to access the Garmin site via URL's to get the same firmwares?

Yes, and you now owe me many beers.

Flattery is a poor substitute for grog, but I'm cheap so that works for me. You're welcome btw, but i'll be sure to pick your brains at some time.

You can find recent firmwares on Andrzej's great site too, and much more:

Yes, by going to 'page source' on the software update page: [Only registered and activated users can see links. ]. I like to use the method in Post #9 with WebUpdater, after it checks for updates to WU itself, click next and then click the link 'View Webpage', when on that right-click anywhere on the page, select 'View Page Source' (or similar depending on browser) from the drop-down and you can then copy/paste the *.gcd download link which is shown between 1) and 2) at the top of that page.
Getting a hell of a thirst now ....

[osiris4isis]

Nice, now I can incorporate downloading in the proggy I'm working on. Wanna beta test it? How thirsty? Enough for Trump's beer? Remember, it's yellow in color.

[Butters]

Sure i'll test it, but wot can I do that you can't? That clockwork 56k modem of yours too slow?

Not that thirsty Sport. I'd rather risk a gas station egg sandwich.

[osiris4isis]

Never asked a software designer to test his own stuffs. Best asked someone with your kind of eyes to. Nothing wrong with downing that egg sandwich with Trump's beer. They go well together. Another question, what is the different between .update and .rgn, do I just remove the 62 bytes at start in .rgn and get .update? Why is .update used instead of .rgn?

P.S. They have 56k now? Damn, I just upgrade from 2400 to 9600 last month. Hah, just thrown away several 2400-9600 modems the other day, it was rusting outside.

Well OK, but as long as it is Beta not deep Alpha [some user assembly required] that you're trying to foist onto me.

Oh yeah?!

Huh? ".update"? You mean ".gcd" i guess. Stop drinking and concentrate. Yeah, something like that in reverse. Remove some sh!t from .gcd to get .rgn really. You're the coder, go code and don't ask me any more trick questions.

Yep! And the latest 56k ones actually run off mains power, no need to wind them up.

Too busy having a go at you and forgot about why to use RGN instead of GCD. I did kinda answer that before, Posts #4 & #8:

.......

• I don't know the 'how' of device being triggered to use the GCD file other than it recognizes that the file is for a different version firmware than the one already loaded. The GCD itself is a bit like a self-loading EXE file, simplistically, in that it contains the same data as an RGN file and additionally (I suppose) a 'header' that directs loading of the new data to the appropriate regions.
• RGN files are a 'stripped-down' version of a GCD and must be loaded manually in preboot mode using Updater.exe.

.........

............ what do I do next to update the unit? Do I have to convert it to .rgn and use Updater.exe? Or can I update the .gcd file directory by just putting it under Garmin directory and reboot? Which method is "safer?"

Using a safely-named RGN and Updater.exe is less risky than using a GCD imho.

To expand that, the reason it's less risky to use an RGN (if it's safely named <HWID>01000<SWV>) is that a corrupt GCD will 'brick' the device, it's easy enough to fix when you know how: use Cure fw to get MSM back. i.e. Load cure fw, delete GCD in mass storage mode and then load original fw. Easy Peasy, but uninformed users freak out big-time. GarminExpress loaded a lot of bad gupdate.gcd files in it's early days. Garmin blamed users disconnecting while updating of course.

Is .update a linux image?

[Butters]

I think the only content of the file is a Linux image. Those Linux-based garmin devices are as dead as a dodo sport. Why the H are you messing about with them? I can't help with testing 'coz I don't have one..... except, I might be able to get my hands on a nuvi 5000 but if you make me brick it I'll have to come after you with a pitchfork and torch.

[Scyllo]

There's only need to delete it, if present, before updating manually by RGN or with GCD on media card.

Hello!

How to manage the deletion of a GUPDATE.gcd on the device (I also do not know if it even exists!), if the device is in a boot loop and is no longer recognized by the PC?

So I can no longer access the device at all.
