Sorry for a long delay.

With an empty card the device boots and works flawlessly. If I put any version of boot.bin on it, I get a bootloop.

rrgn,14,1:/Garmin/14-1.bin
reboot
Tried it, still no success. Mostly because the Updater.exe cannot flash any file to device. I think most promising way is to find a method to circumvent a freeze on the "LOADER LOADING..." stage.

Maybe there is some other program for flashing Garmins except Updater.exe?
