Thread: Garmin Montana 600 «------Big probleme

Hi.
I saw an interesting discussion.
I decided to ask for help. I have two Montana 650.
1. Garmin Montana 650 New. It turns on, boots up, works, but the internal memory is unwritten. Firmware 4.6
Tracks, points are not saved. When a computer is connected, it is detected as a USB memory, but does not allow formatting.
Created RGN firmware 3.6, 3.9, 4.6, 4.7, 4.8, 5.0 - the firmware has been successfully completed, but nothing has changed in the device.
Created RGN firmware 7.6 - an error comes out.
What can be done.
2. Garmin Montana 650 Used. It is stitched with any firmware. But when loading, the test mode crashes. With CURE firmware, the USB storage device is connected and disconnected every 10 seconds.

I tried using SD_Flash_Kit_1275_V590
update.log
