Samsung Galaxy tab4 pad won't start. Died two days ago and method #1 (power + vol up + home button) successfully reset the charger circuit, and it booted fully charged. Stayed charged and worked fine until today. Tried method #1 and then method #2 (power + vol up) but neither worked. Hoping for any suggestions to restart and/or harvest data to avoid factory reset. Tks in advance for any help.
