Thread: IMPORTANT! If you want HELP in case of a bricked Garmin device, please follow this

On your PC go to your Windows system drive > (normally hidden folder) ProgramData > Garmin > Logs > Express where you'll see at least one log file named "Express.log" and perhaps several more named Express_00.log; Express_01.log etc. in date order. If you can't see the ProgramData folder, check below (*).

Starting with the latest (it should be named Express.log) open the files in turn in a text reader and simply search for ".gcd". In the pic behind the spoiler below you can see i've found ".....PrimaryFirmware.006-B1697-00.5.60\software\nuvi55_56_560.gcd" which discloses the last fw loaded by GE to a nuvi 55 with HWID 1697.

You should find in one of your log files either
"....PrimaryFirmware.006-B0972-00.6.30\software\nuvinuvi13xxand14xxseries_GCDFile__630.gcd"
or
".....PrimaryFirmware.006-B1104-00.6.30\software\nuvi13xxand14xxseries_GCDFile-MTK__630.gcd"

That will definitively confirm the original HWID of your 1350 when it was made.

*If you don't see "ProgramData" folder listed in your Windows C:/ drive, you can make it visible and browsable by reading here: [Only registered and activated users can see links. ]. In later versions of Win OS, "Folder Options" is named "File Explorer Options" but the required settings are the same to uncover hidden folders/directories.

Once we're certain of its factory-set HWID we can know how to proceed safely, hopefully without causing more damage to it.

When I search the ExpressDetaled.log files on my W11 PC using "nuvi13xxand14xxseries" as the search term, I get ""https://download.garmin.com/software/nuvi13xxand14xxseries_GCDFile__630.gcd"

I used to run updates from an older W10 PC. I took a look in those log files and this search term produced nothing. However, I have a number of Garmin devices, so I am not sure any Nuvi1350 updates are reflected in those log files.

As you can see, I have little understanding of how Garmin creates these log files and whether they are overwritten with each attempted device update.

I did a search of the ExpressDetailedLog files on my current W11 PC using "nuvi13xxand14xxseries" as the search term and always found "https://download.garmin.com/software/nuvi13xxand14xxseries_GCDFile__630.gcd"

I previously did updates of this Nuvi1350 and other Garmin devices on an older W10 PC and searched those log files, but there was no result on the above search term. I'm not sure how Garmin creates and deletes these log files so those files may be the result of an update of another device.
