How to repair and disassemble when the iPhone7 home button doesn't work or doesn't respond
iPhone7 Home Button Replacement, Disassembly Procedure, Repair Method
[iPhone7 Home button replacement, decomposition method STEP 1]
I think that there are many people who are interested in what parts are used by the home button has become pressure-sensitive type, but i think that it is possible to remove only the home button if you say earlier.
The shape is also very similar to 6s, etc., but the back side was equipped with a delicate chip by the thing that became a pressure-sensitive type!
Please refer to it because it has become an decomposition method that becomes effective when replacing the home button by any chance!
[iPhone7 Home button replacement, decomposition method STEP 2]
I will continue to disassemble the iPhone7 from here, but let's remove each tray of sim card first!
The sim tray can be easily removed using the pins that were included in the accessories at the time of iPhone purchase.
[iPhone7 Home button replacement, decomposition method STEP 3]
Decomposition of the iPhone7 will start from the place where all the screws are removed, but it will be removed from the Torx screwdriver.
[iPhone7 Home button replacement, decomposition method STEP 4]
Since the iPhone7 is waterproof, a waterproof seal is affixed around the inside of the liquid crystal.
The tool in the image is called a heat gun, and it is not necessarily an indispensable tool though it is a tool which made the dryer strong if it says plainly.
If you are new to disassembly of the iPhone itself, you can work smoothly because the seal will be soft if you use it, but it is possible to substitute even a dryer once.
[iPhone7 Home button replacement, decomposition method STEP 5]
Up to now, the iPhone has been to wake the LCD from the home button side to the camera side, but this iPhone7 will open the LCD so as to wake up from left to right.
First of all, the tool is inserted into the position where the spatula is located and it floats little by little, but it becomes easy to disassemble when the suction cup (orange) is used together.
If you try to cause it forcibly, the liquid crystal side will crack, or it will lead to other failures, so we will open it slowly.
[iPhone7 Home button replacement, decomposition method STEP 6]
If you can float the liquid crystal even a little, it is good to insert a pick etc. like the image!
By doing this, the liquid crystal will not close again!
[iPhone7 Home button replacement, decomposition method STEP 7]
Now we will open the gap on the left side.
If you look closely at the inside of the part that could be opened, you will see a black seal or a white seal, but it will peel off regardless because it is a waterproof seal.
[iPhone7 Home button replacement, decomposition method STEP 8]
This time, it is on the right side, but the liquid crystal is floated in the same way as before.
[iPhone7 Home button replacement, decomposition method STEP 9]
A waterproof seal is attached to one lap of the liquid crystal, but please pay attention only around the camera (upper part).
At the moment, I think that I was able to float the liquid crystal of the left and right slightly below, but the upper part does not decompose in the same way because the nail is caught inside, and a little knack is done.
If you pull the liquid crystal lightly in the direction of the arrow, there will be a slight gap between the main body and the liquid crystal, but when the waterproof seal comes into view, please peel off the seal in the gap.
By doing so, it is possible to wake up the LCD panel from the left side to the right side.
[iPhone7 Home button replacement, decomposition method STEP 10]
I was able to open it, but please be careful not to break it because a lot of connectors on the liquid crystal side are connected to the logic board.
[iPhone7 Home button replacement, decomposition method STEP 11]
The first decomposition to be done after opening is work to remove the battery connector from the logic board, but since it is connected under the iron plate of the image, all screws of the red circle part are removed.
Four screws of this part are not Phillips, so please be sure to use a special tool because you can not open it unless you have a Y-shaped screwdriver!
I own several Y-shaped drivers, but I couldn't take them off right away because the sizes were slightly different.
I thought that I would try to disassemble it forcefully as it is, but I am using a special tool because the risk of licking from the experience up to now was high.
[iPhone7 Home button replacement, decomposition method STEP 12]
I was able to remove the iron plate.
I think that it is good to understand the structure of the iPhone7 once in this state.
[iPhone7 Home button replacement, decomposition method STEP 13]
The red arrow part becomes the connector of the battery, but the connector can be removed from the logic board by lifting from the bottom to the top using the tool.
[iPhone7 Home button replacement, decomposition method STEP 14]
Next, the cable on the liquid crystal side is removed, but it decomposes in the same way as the method which removed the connector of the previous battery.
In the previous iPhone series, the connector relationship of the LCD was all gathered on the upper side (upper right), but in the case of the iPhone7, it is one of the changes because it became the lower right!
[iPhone7 Home button replacement, decomposition method STEP 15]
Because there is one more connector under the previous cable, it will also be removed.
[iPhone7 Home button replacement, decomposition method STEP 16]
There is a cable of the camera in this part, but remove the screw attached to the iron plate as if the connector of the liquid crystal was removed.
[iPhone7 Home button replacement, decomposition method STEP 17]
Because there is a connector in the inside when the screw can be removed, it is possible to remove it if it is made to lift from the bottom to the top.
[iPhone7 Home button replacement, decomposition method STEP 18]
Now it was possible to separate the body side and the liquid crystal side of the iPhone7.
The front camera is on the LCD side and the rear camera is on the main body side, so I would like to disassemble each one.
[iPhone7 Home button replacement, decomposition method STEP 19]
Because the home button is on the liquid crystal side, it decomposes, but it cannot be removed if it is not a Phillips screwdriver but a Y-shaped driver.
Use a dedicated screwdriver to remove all screws that are enclosed in red circles.
[iPhone7 Home button replacement, decomposition method STEP 20]
I think that It was possible to remove each plate when the screw can be removed, but please keep it so that it does not understand because the length and the thickness of each screw are different.
[iPhone7 Home button replacement, decomposition method STEP 21]
The home button is connected to only one connector extending from the liquid crystal side, so remove it.
[iPhone7 Home button replacement, decomposition method STEP 22]
The cable part is only fixed with double-sided tape, so let's peel off using the tool!
You can see that the cable has a small chip, but please be careful because Touch ID will fail if you bend this part!
