When i tried to open the front panel , the right side suddenly opened.

and the plastic frame at the upper right corner left the screen.

How could i repair that ?

I have the same problem in iphone 5C

Another comment : why the instructions didn't disconnect battery first ?

every thing is perfect. i had enjoyed working in my iPhone through this wonderful guide.

but , the sensitivity of home button isn't good. i need to press the button heavily to respond.

what should i do ?
