My friend's 6 months old unblock 4 doesn't turn on. When he try to turn on it show a black screen and a message said "unsupported mode" . Any body seen this before. He try to reset the box but won't help. He can't go to the desk top to reset to original. The pin hold at the back doesn't work either. Thank you!
