I have a couple of Sunray Solo2 boxes suffering from the same issue and no matter what image I flash the issue remains. They are taking the image and booting, but after about 5 seconds the boxes simply hang. The screen freezes and becomes totally unresponsive.

I could be wrong but I don't think this is related to the flash chip as the box will flash and then boot. The issue occurs after booting.

I've searched on here and on google but haven't found anyone else with similar issues but I'm wondering if anyone else has come across this and if there is a fix?
