Thread: Nuvi 54LM: Shutdowns in ~2 secs after reflash

If i flash it use the CURE option, the drive and sdcard will appear momentarily for 2-3 secs before they shutdown. I was able to copy it during this time.

The only time the drive and sdcard appears in explorer is when i use the CURE option. But the device will shutdown in 2 secs.

When flashed in original mode, Garmin Express, G7ToWin, GarminCure3 and every other software can see and talk to the device. Below is an excerpt from G7ToWin. (but it won't show in explorer or windows disk management). Cleaned the port and tried on USB 3 ports and USB powered hubs as well.

Am able to select different voices and vehicles. The renaming of nuvix2andx4_GCDFile__390.gcd to GUPDATE.GCD and booting from sdcard\garmin\GUPDATE.GCD location did not trigger a flash.

Hope the garmindevice.xml provides some clues...
