Maybe you have reserved the config files when you upgrade. reset the router clears the config files.
If you want to go back, you can connect your computer to ssid “openwrt” and then you will be able to access http://192.168.8.1/cgi-bin/luci, there will be a UI to reflash the firmware.
Also you can use uboot web UI, check this: 404 Page not found - GL.iNet
For onion sites, I have tried some. I used tor browser and the mini router and achieved the same result. Some sites are unable to connect. Maybe they are down?
