ATV1 - stuck in XBMC web viewer

G’day, I downloaded and installed ATV-flash on my my ATV1. While trying to get the Pseudo TV settings done, I entered something like a Web Viewer? anyway, I can’t seem to get out of this program. It appears to be able to receive input from a mouse and/or keyboard, but it doesn’t seem to accept my keyboard or mouse?

I am reluctant to force a soft or hard boot - the last time this happened, the ATV performed a factory reset without any input from me and I was back to the original OS.

Any ideas on how to help me?

thank you

Had to force a restart, but thankfully, there were no issues.
