Firstly, apologies if this is answered elsewhere, if so please direct me. I've had a Minix Neo U1 for some time but recently I can't access the "Settings". The screen flickers & just comes back to the main selection. Is there a way to reset the box to Factory settings ?? Obviously I can't get into the "Settings" to do it. I've googled it and have yet to find an answer. Alternately, if there's another way to get into "Settings" that would suffice too. Thanks.
