Hi Franky,
Should be straightforward to get your Single-Board RIO back in a usable state.
This tutorial walks through (re)installing Software on a CompactRIO (or Single-Board RIO) target.

If you are having any issues detecting the target in MAX (Measurement and Automation Explorer), then this article walks through debug techiques.

For software purposes, CompactRIO and Single-Board RIO are essentially interchangable. The underlying hardware architecture between both targets is the same, so the process to load software or compile code is the same. I didn't want you to be alarmed that I'm pointing you to CompactRIO turtorials.
Hope this helps,
