Chosen Solution
So, I was dumb and opened my iphone and tried to do something, when i putted everything back my phone couldn’t close to the end on the top left corner, so there is a space on the whole top side which cant close to end, and when i turned on iphone there were some white lines and things like that, you can see everything in the pictures. What did I mess, and how much money does fixing something like this costs ?
It looks like you might have done some damage to your LCD or LCD flex cables unfortunately :( Try opening the phone again and inspecting the flex cables, making sure each one is free of damage and is seated and connected properly. Then, when you try and close the phone up again, make sure that the tabs at the top edge of the screen hook into the frame before you try and seat the screen in place (take a close look at step 12 in this tutorial for more clarity). If your flex cables seat properly and they aren’t damaged then there is likely damage to the LCD and would need to be replaced. Hope this helps!
