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

@Butters

Thanks again. I read and tried to follow the instructions but I fail at the very first part. I can't get my HWID number on the watch via the G7towin tool.

Also, while trying to make a cure fw, I cannot even start because it asks for a gcd file and all the firmwares I was able to download from garmin and perry's web are already rgn files

When using the G7towin tool it somhows recognizes the watch connected because, if I do the proccess without the watch, it inmediatly pop ups the message. If I do it with the watch connected and in pre-boot mode, it takes a few seconds thinking but then fails.

I'm starting to think the watch is more than dead.

Thanks for all your help.

Hello--

I have a Rino 650 and 655t that I acquired second hand. They would freeze as they powered up displaying "updating waypoints and trackways". I used GarminCure3 to get access to USB mass storage. I installed FW 1247 and SW 5.10. Garmin Express crashes on my PC when I try to start it, but Garmin's other applications (BaseCamp, MapInstaller, etc) work to update software, and I can navigate the devices' memories via USB.

Now I can't get the devices out of USB. When I disconnect them and power them up, I get the Garmin logo and the USB symbol. The devices shut off shortly thereafter. I have deleted GUPDATE.GDC, but it looks like there's something else interfering with startup. I have other, functional devices to serve as templates, and don't see anything obviously interfering.

Thanks much for your thoughts.

Joe
