hasanacar, Nov 28, 2015 : Hello guys nd ladies, Today I ve dropped my opo from around 1 meter height to concrete ground... and I was so sad cause I thought the screen was broken.. It was fortunately not broken, but it was unresponsive to anythng with screen on. anythung I tried did not help. So I shit down my opo long pressing power button... but it did not come back... Then I tried to hook it up to a power bank, firs I got no action but after a while I saw the battery icon, being charged around %75... but poor button was still not helping to turn on the phone. then I turned it off again long pressing power button. but after that point. My opo is completely black screen in any case. I hooked it up to my original charger. I long pressed power button for 20 secs 5 time. volume down + power button.... no luck.... what do you think , my problem can relate to ? do you have any suggestions ? I ve no warranty..
