Tomtom Go 520. After attempting an update the device crashed half way through and now just keeps disconnecting and rebooting without ever showing the maps screen. It hangs for a few seconds on a screen that says that there are no maps installed (seems they were removed during update) and I need to install a map to continue. When I hit install map it just reboots and I never actually see a map to install. I've tried soft reset and reset from the black screen with white writing many times. It says that the device is being recovered, gets to 100% then just starts the endless rebooting cycle again. I have tried these dozens of times with the same outcome. I had it running all night and all I hear is the drums as it continually reboots. Tomtom customer service has not responded to my emails. Online Bot tells me to do a factory reset which is impossible because I can't get into the menu to do this. I can only connect through MyDrive. Tomtom Home doesn't recognise the device. I cannot find a way to flash the firmware. Any help would be greatly appreciated. Thanks.
