    Default Nuvi 3790T 'Loading maps' - Device Memory Problem?

    Hello people,
    First post so please go easy!

    I am trying to help a friends 3790T which is stuck on the 'Loading maps' screen at boot.
    I followed ddabcd277's [Only registered and activated users can see links. ] on changing drive letters in the device memory.
    It was complicated but I could do it and it enabled the device to boot up.
    However it still doesn't work properly with the modified .rgn file - it has errors 'fm traffic provider database missing', 'acquiring satellites' - 'trouble finding satellites', no maps, webupdate does not update properly etc.
    But when I restore original .rgn (latest version 5.00) it is still stuck on 'Loading maps.'
    Before changing the drive letters I deleted random .poi, .img, .tracks etc. files on it [Only registered and activated users can see links. ] catymag.
    Unfortunately I did not make a backup of the original.
    I tried to reformat with [Only registered and activated users can see links. ] with original settings, but it went into a restart loop.

    Does anyone have any advice please?

    Many thanks,

    Have you used [Only registered and activated users can see links. ]

    Basic Instructions
    Load firmware in cure mode (This Firmware is not bootable and will give u reboot loop if not connected to USB)
    Format using rmprepusb as per thread.
    Create empty folder named garmin (not always necessary but advisable)
    Load Firmware in original mode.
    Connect to Webupdater to restore files.
    Load Maps etc etc as needed.

    You ar in restart loop becouse you have damaged voice or text file.

    Remove folder voice, keyboards and text and turn off/On your nuvi and run webupdater to download this deleted file.

    If you still have restart loop then folow Dasil tutorial
    If you wish, you can [Only registered and activated users can see links. ]

    Thanks, I'll check/try those things in the next few days. I actually did the other things a few months ago so will need to familiarize myself with it again.
    Will get back then.
    Regards, Tom
