i tried to web tplink firmware update the upgradesys file to the router which was incorrect, should have used the factory image. anyway i bricked the router but for some reason is accessible via 224.0.0.251 pc side asking for bootp requests via static link. the uart cables are a mystery for some reason or another will refuse to give a link. someone mentioned 2 bridges to solder somewhere but there were no pictures ide found at the time.
