Ok desperate here,my sons galaxy Tab2 is locked with a pin lock and pattern lock, problem is, a young sprog got a hold of it and promptly kept putting in the incorrect pattern lock and it is now asking for it be unlocked. Of course he has also forgotten his pin lock. After googling, another issue is that it was locked out with wi fi off which is also a problem apparently!! Tried the old power off and hold the vol button down but I aint seeing recovery mode, any ideas ??
