Same thing with my Galaxy Tab 3. Instead of holding power/volume buttons simultaneously, removing sim/data card, prying off back, plug into power source, etc. etc. etc....I tried this;
- turn unit face down. Place in dirty catbox. With left foot, place firmly on back of unit and slide back-and-forth through dirty catbox.
- remove unit with salad tongs & place face-down in toilet bowl. Let float. Watch one quarter of NFL Football on Fox. Return to toilet bowl. Urinate on floating unit. When finished, have someone else remove unit from toilet.
- have someone hold unit like a football on a kicking tee. Stand back two paces, then step in one motion towards ball. Kick unit like extra point towards front door. With front door open, pick up said unit . Turn said unit on side, elbows out, bring arm back - and with one motion, fling unit out front door, over hedge, skidding across pavement into road.
- return to your regulary scheduled bad habits.
Hope this helps. It worked for me.
