Hi, I have a complicated problem in my nuvi 1390T. I've tried different cures firmwares, that I've done following criteria established, including the solutions of this topic, but without success. The Nuvi enters in pre-boot, writes the firmware, but freezes on the logo Garmin at startup or enters in looping boot (depending on the firmware), with or without SD card. Quite possibly it may be some bad sector in the Boot Block, if the memory follow the same principle of Roms of motherboards, but I have no idea how to access this sector and what code should I change... I accept suggestions. Tks
