I am fairly new to the ATV1 OSMC/Kodi world so please forgive me if any solutions are obvious.
I was able to format an 8gb USB drive to boot OSMC on my ATV. I removed the USB and waited 10s, like prompted, and then turned on my ATV1, then a blue screen saying installing files, booting, etc. showed up followed by a "successfully installed " message. It then booted up once more to a blue screen with a blue OSMC logo.
At this point, I thought I had done everything successfully but low and behold, once it finished loading it just shut off (or appears off). I know the connections to my tv work because I plugged my original ATV1 to it before and was able to set up wireless network to it.
****I am using the rgb component in connectors not an HDMI because my TV is old
