Disassembly of iPhone 7

To prepare the instructions, the original switch-on phone was used. The first thing that any repair begins with is the primary diagnosis.

At the same time, you should pay attention to:

  • scrolled Pentalobe screws,
  • the status of the display and the phone case,
  • check the operation of the Home button (including hypersensitivity)
  • connect to the USB-tester and check the phone’s charge circuit
  • check the operation of the audio codec
  • check whether the phone catches the network

Next, unscrew the Pentalobe screws and install the suction cup on the display, in the area of the Home button.

We carefully use a plastic pick to trace the perimeter of the display, thereby separating the display module from the case. Remember about the U10 chip, which can easily be damaged.

Then you need to move the display slightly down and remove the screen guides from the iPhone case.

Open the display to the right and in order to keep the loops in good condition, install the suction cup and place the display on it. In no case, do not place the display with the connected cables horizontally on the mat. Otherwise, the cables or connectors on the board may be damaged.

When completely disassembling the phone, pay attention to the layout of the screws and components of the smartphone, on the magnetic mat. The correct layout will help to observe the main rule of the master, when performing any repairs, “Do no harm” or do not make it worse.

If the phone has not been opened before, we use a separator for putting up display modules.

Unscrew the lock of the display module and battery cables with a three-beam screwdriver.

Carefully remove the lock to the side and disconnect the battery connector.

Remember that the primary power circuit is formed when the battery is connected before pressing the power button. Therefore, we use a dielectric object. A detailed checklist for replacing the battery can be found in the article Replacing the iPhone battery.

We proceed to the complete disassembly of the phone case:

  • We remove the power source (battery capacity in the seven 1960 mA * h). If the battery was previously changed in the phone, then it is quite easy to remove it using a plastic spatula. Additionally, you can use a separator or any solvent (BR-2, medical alcohol). If the battery has not been removed before, first of all it is necessary to dismantle the vibration motor. And only then pulling the tabs of the factory double-sided tape to pull them out using tweezers (it is recommended to pull the tape as horizontally as possible so as not to tear it).
