Default [Q] Safestrap Failure

I followed the video exactly and when I get to the point of the first Restore (around 9:00), it says "Restore Complete - Failed". There is a button to Reboot System. When I tap that, the phone won't turn on. I have to pull the battery to get it back on. I guess I'll be uninstalling Safestrap. If I "Uninstall Recovery" from the stock ROM slot, will the space be freed up again and the phone be returned to the same state as before I tried using Safestrap?
