Reset an apparently dead Samsung Galaxy Tab S 8.4″
…with this one simple trick! I had my Samsung Galaxy Tab S 8.4″ Android tablet spontaneously die last night, and it refused to respond to any button pressing, cable connecting or threats. Holding down the power button for 10 seconds (or more) did nothing, as did Dr. Google’s top tip of holding down Power, Volume Up and Home for 10 seconds. What worked for me was holding down Power, Volume Up and Volume Down for 10 seconds. It restarted without anything being lost and is now back to normal.
