Surprisingely i was able to detach the Backcover by just using a simple creditcard. I sharpened the long side of the card with a knife to slide in better. I bend the backcover firmly by pressing it away from the front by using my thumbs - press away the plastic cover to receive a small slot (both hands needed). I inserted the creditcard into this small gap, moved it along a few times and the complete side was detachable at a glance. —>> The creditcard is long enough to press down all 5 plastic-hinges. Perfect sollution to me, try it. No scratches, no bending - easy peazy. Step 2-6 arent necessary with this solution. Sorry for my plain english. Greetings, Sören from Germany
