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

Hello there. It's amazing to see such a thread with great info on how to fix a Garmin.

Unfortunately I still need to make a post as something peculiar seems to happen with my Garmin. In short, I tried all fixes from the opening post and more. The device/program fails whenever the internet storage is accessed.

Using windows 10

1) Bricked device MODEL, Firmware version, HWID.
GPSMAP 62st, 4.80 (although self test shows 7.20 after trying flash, Updater still shows 4.80), 1113

2) Why and how the device got bricked.
It started when someone downloaded maps from somewhere. After this point the device started to have trouble starting. Sometimes it worked for a while and then crashed. Now it seems to never pass 'loading waypoints, tracks and routes..'

Since this is a second hand unit it might be a previously existing hardware problem that happened to coincide with the uploading of new maps.

3) Symptoms: what's wrong in your device?
It never passes loading waypoints during startup.
It is recognized but any communication with the device fails.
for example. Flashing can start but fails.
Calling for the HWID I can see the firmware version, HWID, but device ID shows 0. I also get an error "USB Error: WaitComplete: Error waiting for overlapped I/O"
Opening device properties in windows, opening device manager etc is all very very slow or never responding.

4) Does your pc sees your device ?
Not when normally connecting and starting.
The device is recognized in preboot and Mass storage mode
Garmin express never recognizes it.
WebUpdater only in preboot mode.
RMPrep only in Mass Storage
Basecamp never (not sure)
g7towin only in preboot

5) List all the procedures you already tried to unbrick it and their results and errors messages obtained.
-I've tried webupdater in preboot mode. Error message: 'update is damaged' (sorry not sure on the exacte message, this is translated), when trying again it shows device is not responding.
-I've tried GarminCure, both Cure and Original > Updater. it instantly goes to 100%. After a while it shows a generic error: 'There is a problem with this Garmin Application'. The error messages doesn't look important. The device stays recognizable. Upon trying flash again it says the version is the same, yes, utility disappears after a few seconds.
-I've tried formatting it, but as soon as the device enters mass storage mode the utility is 'not responding', same goes for explorer in general if I try to open the garmin's storage.
-Master reset, freezes after pressing 'yes', shuts off after 10s or so.
-Self test freezes and shuts off after 25s or so. RAM passes but ROM is still at WAIT.

I suspect there is either something with ROM or I/O. In that case, should I blast it with a Hot air rework station?
