If anyone factory reset android tv without oem remote or the remote was discontinued read this. I bought 3 different remote off Amazon with no luck pairing and was stuck on the set up welcome page. 2 weeks later I finally went and bought a cheap USB mouse from Walmart and connected to tv USB port. It worked and I finally set up tv without remote. It only works on Android tvs I believe. I have a xbr-43x800d sony bravia tv. Hope this helps someone!
