One of the most complicated fixes on an iPhone is a screen replacement fix, make sure to have enough time to complete the job before you attempt this repair, and have simple room for your iPhone and the new panel to sit in while operating on it.
The iPhone needs to be completely disassembled for a new screen fix, so I would say that before beginning the repair you have a few little pieces of paper to mark the bits, and I’m particular to the location of the screws. Mark them as follows; Metal Back Screws, aluminium back cover, and motherboard-in this order, set them out on the desk with a small space between them for the other iPhone parts and new panel to lie in.

The tools and equipment needed for this repair are: a case opener, a small Phillips screwdriver, a paper clip to eject the SIM tray and an iPhone replacement screen, once you have these to handle and the paper labels are lined up. Make sure to have hands clean before repair begins.
Next detach the SIM tray-do this by placing the paper clip in the slot next to the power button on the top side of the iPhone, the SIM tray should be removed when the clip is placed. First, use the opener to cut the iPhone’s plastic backrest. Place these two parts next to the paper stickers, you’ll need to reverse the order of these directions to reassemble the iPhone after you have installed the new screen into your iPhone. For this purpose I would suggest placing them next to the aluminum paper mark as far away from you as possible.
The next step is to remove the two tiny screws that hold the metal casing on either side of the back and another screw that is situated at the tip, in the center of where you cut the plastic back-placing them on the sticker. After completion of this, take the case opener again and push it gently on both sides of the iPhone to ease the back away from the frame-you’ll find the metal back is protected by a wire cord, cautiously remove this from the iPhone’s main section, not the metal rear end.
The next move in fixing the screen requires patience-removing the iPhone antenna cord, bound by glue in three places, carefully pry it loose from the glue spots is needed. You will then need to extract 10 screws from around the iPhone’s sides and position them on the’ Outside Case ‘ paper sticker-after that detach the 3 screws that protect the motherboard. You will disconnect the processor as they are soldered together at the same time as the battery, and once you have achieved this you can gently extract the remaining iPhone case.
The next step is to detach the LCD screen to suit the new device-this may be the hardest part of the restoration, and it needs to be done with extreme caution. Loosen the 3 clips on the screen’s sides and start removing the Oled gradually, you’ll see some wires entangled in the Iphone-guide them carefully through the frame and slide right through.
After completion of this, take the replacement of the iPhone screen and install it into the unit, closely follow the steps to ensure no mistakes are created when the iPhone is installed back to its original state.
