I've had Code 101 myself when updating to Dingo. I just tried again later.

Try turning your eDGe off, then turn the power back on. Then try the update again.

Note that the update is not one process, but several.

First, run the Update application. This wills start the update. When you click "Ok", it will look like nothing is happening, but you'll notice on the top of the screen a new icon with red numbers going from 0 slowly up to 100. This means the update is downloading (takes 5-10 minutes).

When the red number reaches 100, the icon will change, indicating an update has been downloaded. Press the "Menu" button, then "Notifications", then tap the "System update ready to install". This will launch the actual setup.

Acknowledge the various messages, after which your eDGe will reboot once or twice during the installation. This will take about 5 minutes.

Give this a try and see what happens.
