Put Updater exe and your rgn in the same folder.
Open Updater.exe and drag the file in Updater icon.
Tick USB and flash.

I cannot seem to get into preboot mode. I've tried lots of combos of pressing lcd screen, connecting to PC, holding power down. I have a magnet taped onto the back to simulate the battery door being closed. I'm so frustrated right now.... somehow I got it into preboot mode once because I ran the cure rgn on it. now I can't seem to get there again in order to put the original firmware back on. My computer sees it, sees the files on it, the garmin express software sees it, webupdater sees it. However, the garmin will not boot past the splash screen -- I am stuck in mass storage mode. Any additional advice would be really appreciated!!!!

Thanks,
Jamie
