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

Letting the device sit with the battery disconnected did not resolve the problem. The nuvi just goes into mass storage mode instead of pre-boot no matter what I do. Oh, well.

What is NV?

Maybe it's because of some hardware problem?

NV is a region in flash chip where firmware stores lots of info. Also while in factory it's programmed with your UnitID. Pre-boot mode issues are not related to NV. You can erase it completely and pre-boot would still work.

That is what I suspect. It looks like the device is no longer properly processing the signal from the power button and/or the touchscreen anymore.
