Chosen Solution
I purchased for an iPhone 5S a Power On/Off Lock Mute & Volume Switch Button Flex Ribbon Cable and tried to install it myself. Everything went OK except one small jumper that fell-off and now I cannot identify its location. It must be located in the upper part of the chassis between back camera and vibrator. This jumper is 0.8cm long, color is black and difficult to read a number 486 (I believe) on it. One end is closed for a screw to fix, the other end is open for the screw to fix and both ends of this jumper are twisted at 90 degrees. Thanks in advance for your answer.
Take a look at the 5S Upper Component Cable guide, specifically steps 58 & 59. iPhone 5s Upper Component Cable Replacement That’s where it goes!
