What device do you have? What exactly happens on welcome page? If you wait for a couple of minutes does the time in the top-right corner change or is it stuck on 12:00?
It is tested on DroidTV MX and G-Box Midnight MX2. Both have the same IR remote (see the pictures). If your device has different remote try connecting USB keyboard.
I have G-BOX MX2 from matricom. After welcome page show up, I can't move forward on next buttom (stuck on welcome page). I already wait a lot of time, but nothing happened. I also connect a mouse and click in next button, but no move forward.
