If you have cracks in your iPhone screen, you will want to have this repaired. There are several options available for repairing your screen and one of them is to do it yourself. To repair your screen you will need to take a number of steps and it is important that this is done correctly to ensure your phone continues to work correctly.
Should You DIY The Screen Repair?
Before you start repairing your screen yourself, you need to consider if this is the right option. If you have AppleCare+, you can have 2 accidental damages repaired by Apple for no additional costs. If you have any other form of gadget insurance, the repair may also be covered by your policy. It is important that you carefully consider these options before you start any DIY work.
Power Off And Remove Dock Screws
The first step to repairing your screen is to power off the phone. It is important that the phone is completely powered down before you start any other steps. At this point, you should note that you could be voiding the warranty on your phone by replacing the screen of your phone.
Once the phone has been powered down, you will need to remove the dock screws. You should use a 5-point or security screwdriver to remove the 2 screws which are found on either side of the Lightning Dock. These screws are fairly small, so it is important that you put them somewhere safe.
Remove The Broken Screen
Once the screws are undone, you can attach a suction cup to the bottom of the display. The cup should be above the home button. You should then pull the display up carefully as there are a number of cables at the top of the display. You need to swing the display up enough to show the top right where the cables sit.
Using a #000 Philips screwdriver, you need to remove the 5 screws in the top right of the phone. You must not mix these screws up as they are all different sizes. You can then remove the display shield with a pair of tweezers. There will be 4 cables holding the display to the logic board and you need to remove them. You need to be careful when doing this and only touch the cables.
Transfer The Touch ID
On the back of the broken screen, you need to remove 2 screws holding the Touch ID shield. You should then use the pointed end of the spudger tool to remove the cable. After this, you can gently push the home button out of the broken display. You should then place the home button and touch ID assembly into the replacement screen display.
Once you have done this, you will be able to install the new display. You will have to attach the cables to the logic board in reverse order. Once this has been done, you should replace all of the screws and carefully ease the display back into place.
