I have an OP1 since 2016 lying around and won't boot. Every now and again I hook it up to USB for a charge, otherwise, its the most expensive paperweight I have ever had. Last I heard, I should send it off to Sweden and have the Mainboard replaced for a few hundred euros. Absolute disgrace, as it seems just a mainboard bug. I can still run all the test (switch on & hold com) and it comes out ok on all test. But it won't boot and won't respond to software update. At first I had a few cool ideas and uses for this unit but now its just a reminder of how bad a modern startup company treats customers with trouble, especially since its obviously a product bug and not user induced. Piece of crap.....
