Thread: GarminCure3 tool - the new way to create cure firmwares for Garmin devices

Thanks for responding, kunix. Unfortunately, the same thing happened. Here's what I did on my native Windows 7 Ultimate machine:

1. I generated the 097201000610.rgn file from GarminCure3.exe using CURE and using nuvi13xxand14xxseries_GCDFile__610.gcd
2. I manually ran Updater.exe 097201000610.rgn (Updater.exe is v2.8.0)
3. Clicked on button for USB Device
4. Clicked and held upper left hand corner of Nuvi 1390
5. Plugged in USB cable to Nuvi
6. As soon as my Nuvi device appeared in USB Device box on computer, I immediately clicked on OK
7. Then the Updating Software window appeared which said this:
nuvi 13xx Series Software Version 4.20
Updating...
100% complete, 0:00 remaining
Note: The USB connection audibly dropped and re-connected once or twice during the Update process
Then the window changed to this:
nuvi 13xx Series Software Version 4.20
Erasing...
(this may take a few minutes)
Then this window popped up:
The GARMIN device is unable to program the requested memory region.
This could be due to an incompatibility between this application and the GARMIN device.
If this error continues to occur, please contact GARMIN Technical Support.

What is odd is that if I do the hold upper left hand corner process and plug in cable, the machine recognizes the Garmin device for about 30 seconds, but the machine is unable to access this like a drive during this period (I tried finding it with Windows Disk Management as well). If I run the updater, the updater seems to knock out the connection within in the first couple of seconds. The USB connection continues to open and close during this period. My thought is that my machine is working fine trying to establish a connection with the nuvi connected to USB. Is there anything else I can try? Or is there another way to wipe this device to get it out of boot loop and then flash the rgn file?
