Sounds like you had some hardware issue. My first steamdeck had a bad battery (it wouldn't last more than like 15 minutes, really flaky). I spent some time troubleshooting (as per valve supports direction) and everything kind of always worked (when plugged in anyway). The buttons, going to "desktop mode", going back to the steam app. They had me install steamos again from a usb stick oddly. It didn't help. After trying a few things they sent me a new one, and its been great. There was some wierdness in selecting the controller, but that seems to have been resolved. It should have an hdmi port and a usbA port... instead of the solitary usb. This would have made the os reinstall so much easier.
