Here is a manual way to install the updates:
With your smart phone, download DFU app published by Nordic:
Save the two files from this email to your phone.
(The one that begins with "remote" is for the controller. The other with "Mainboard" is for the board)
Within the DFU app there are 3 simple outlined steps:
Step 1 - Select the firmware file to be uploaded. Direct the app to the file you saved to your smart phone.
Step 2 - Select the device you wish to update. In order to make the device visible to the app, you will need to put the device into "service mode".
On the eBox, this is accomplished by holding the reset button down while you momentarily press the power button: Board's Service Mode
Similarly, on the hand controller you will need to press the menu button while momentarily pressing the power button: Standard Hand Controller's Service Mode
(Please note nothing will be shown on the screen to indicate "service mode", but the device should appear for selection within the app)
Repeat the steps for the other file.
