Then it is some other file/files causing the problem.
Check if there are any map files in ".System" folder of your backup other than with "gmapbmap" naming. If there are such files in .System of the backup, then re-flash the device with Cure firmware to get PC access and remove any map IMG files and other associated files like UNL and GMA. GarminExpress doesn't renew basemaps so it should be safe to leave gmapbmap.img in place as it will be the OEM factory loaded originally.
If there are no other detail maps in .System, then after flashing cure fw you could progressively remove other files like GPI files from POI folder, Voice files, etc., starting with files showing recent creation dates. If you'd rather not bother with that then you can remove everything and just leave an empty GARMIN folder in the root of the internal memory. If it boots with just a GARMIN folder you can replace much of the content including map entitlement via GarminExpress. If necessary it can be reformated but don't use the Windows built-in tool for that! It may not work properly, we need to use a specialized tool named RMPrepUSB with particular settings to ensure it works properly.
PS: Of course you'll need to re-flash Original fw again after removing files and before trying a boot.B1ng0 Reviewed by B1ng0 on . nuvi 3790 hi i have problem with nuvi 3790, after loading logo Garmin, apear SYSTEM SOFTWARE MISSING , can you for HWID 1101, software version 510 prepare Sd patch.
