    Default Flashing a stuck 3790

    Hello everybody! i am new to this forum. My name is Christophe and i am french.

    I have a 3790 that is stuck at the "loading map" level, with no mass storage access from my PC. This happened after a map update and a system update (using WebUpdater)
    Garmin offered me to fix it for $150 but since a refurbished one is about $180, i bought another one.

    Now the problem: i am trying to fix the old Garmin by myself;
    extracting the GUPDATE.GCD from the refurbished nüvi, i built a cure .rgn using GarminCure3
    In pre-boot mode, i flashed the Garmin and managed to get access to the mass-storage, removed the (faulty?) map and restarted. Of course the cure .rgn doesn't allow more than access to the mass-storage, so i ran the WebUpdater: message was "updating from current 000 system to 4.90"... but after "successful update" and reboot, i found the 3790 was still running the cure .rgn (boots and then shuts down after ten seconds)
    Using the updater.exe, i managed to reinstall the GUPDATE.GCD (4.90) from the refurbished Garmin but this brought me back to step one: stuck at the "loading map" level and again, with no mass storage access.

    I would be very grateful if somebody could advise me at what to do at this point?

    Thank you!

    Done: i reformatted the 3790 using RMPrepUSB, then copied all the files back using Disk Utility on my Mac and it worked! thanks a lot for your help!
