My tablet a Samsung 78 tab is locked and I am unable to remember the password. Apparently it lacks a firmware necessary 2 do a hard restart on the the tablet. I am unable to use the volume keys and the power button to get to the safe mode this is a known firmware problem by Samsung and in order to fix they said I had to send it in to them and they would have to do a complete factory reset. It is no longer under warranty and this will cost me money. Has there been a firmware update or a workaround to unlock my tablet yet. It happened shortly after I bought it and have never got to really use it please help
