Garmin edge 840 in boot loop after updating map

I can't download the Western Europe map, it always gets stuck a 59.7%. It's not a problem with my computer or my network because I can download Central Europe map without any problems. Due to failed map installation, the device fails to load the map during the boot process and it gets tstuck in a endless boot loop. 

If by some miracle, Garmin Express detects the device and I delete all the maps, then it will boot normally... until I try to install the Western Europe map again. 

The device has enough space to install the map, it is almost empty.
