I have an older X50 and it performs the intial boot-up, I can see the booting screen. It then opens the web browser interface and localhost is in the browser box, but it just spins from there and does not open the controller interface. Any ideas on how I could proceed? Thanks for any help. ---

I am also stuck on “waiting for localhost”. I flashed the SD card and reinstalled, but still having the same issue. ---

Sometimes the sd cards will wear out (finite amount of read write). You may want to try a new one. ---
