Why can't I turn on my iPhone 6S?
After having water-damaged, I go to an independent store and have them clean the logic board of my iphone until it can function like usual.
It turned off by itself a several times but after I waited several hours or two days, I can turn it on again.
but now, its been 3 days and i have tried rebooting, or plug it in charge it still can't be on. I tried to connect to the iTunes, it can still connected but the iTunes said the phone is locked and I need to unlock it (the phone won't turn on)
What should I do? is this related to the phone machine? or maybe the LCD?
Is this a good question?
