reComputer Jetson-10 not restarting

After running a step by step tutorial on installing openCV with GPU support I got the message that the disk was full. I was able to free up some memory but not sufficient to restart the compiling. I had to shut the unit down because of time constraints I had at the time. And now it won’t startup anymore.
Could this be because of insufficient disk space?
Is it possible to reset the installation to factory setup? If so: how do I do this?
