I cannot think of any other reason why it wouldn't work. I have been researching this for hours now, and don't know what else I can try other than buying another RPi really.
So my last resort is to ask you troubleshooters if you know what the problem is.
Please could you post in the other topic to keep everything together, but I will need this to be bumped occasionally to spread some awareness here too, as this is more dedicated to troubleshooting, and the general forum could be for anything.
Please help me get my Pi working!
