Thread: Running programs from SD on nuvi

I've seen a similar error [Only registered and activated users can see links. ]. Can you flash an RGN file with the original firmware?
0C 80 A0 E3 is the right patch for nuvi 12xx, it should work on a healthy device.
Also you can try [Only registered and activated users can see links. ] to access the internal flash drive. It's almost the same as QuickCure3.rgn, but it has a flasher application.

Unfortunately I was not able to access garmin internal flash drive. The tool will be successful in downloading the payload but the garmin will revert to flashing garmin logo. Here is the text output from tool.
