Hi, I’m posting this so that others might not lose as much time as I did.
In the RKB, there are two paragraphs that I misunderstood and thus wasted several hours of frustration. Here they are (further comments below):
==================
4. Writing to a USB flash drive (from a second computer, not the NUC):
Now that you’ve downloaded the image to another computer, you will need to write this image to a USB flash drive.
Windows / Mac OS / Linux
- Plug in your USB flash drive (it must be larger than the factory reset image size – 1GB is more than enough).
- Download and install Etcher from https://etcher.io/
- Start Etcher
- From the Etcher application interface, select your
.img.gz
file as “the image” - From the Etcher application interface, select your USB flash drive as “the drive”
- Click on “Flash!”
Linux Command Line
- Uncompress your .img.gz file by running
gzip -d roonbox-linuxx64-nuc3-usb-factoryreset.img.gz
, which will leave you with a.img
file. - Plug in your USB flash drive (it must be larger than the factory reset image size – 1GB is more than enough).
- Run
sudo dmesg
to determine the device name given to your USB flash drive. It will be something like/dev/sdb
. - Unmount any directory your flash drive was mounted to.
- Run
sudo dd bs=10485760 if=roonbox-linuxx64-nuc3-usb-factoryreset.img of=/dev/sdb
(replace “sdb
” with the appropriate device name). This can take a few minutes, depending on the speed of your USB flash drive.

I am not wholly lacking in intelligence, but I did misinterpret the above paras to be part of a continuous set of instructions. So, having used Etcher, I then tried to use the CLI instructions.
I may be the only person who will ever make this mistake. But could they be clearer? Could there be a line that says (please do ONE of the following)?
