[quote=104460]That lovely little square is telling you you have an insufficient power supply. You need 2A 5V. Sometimes cables can be bad even if your power supply is good. Get a new adapter. I use one from amazon from kootek that seems to work fine for me.

I had this issue and all i had to do was use a shorter usb cable. In some cases it is the power supply but if you have a smaller wire i would try that before changing power supply.
p.s it’s not a stupid question lol.
