iPhone7 Plus LCD cracking, screen replacement repair method, disassembly method

: Here, when replacing the battery of the iPhone7 Plus, we introduce the decomposition method.
There is no particularly difficult point if you have done the battery replacement of the iPhone in the past!
For the first time, it is necessary to disassemble the LCD panel to remove the battery, but the lcd panel decomposition method of iPhone7Plus is different from the previous iPhone, so be careful. I don't think there is any difficult task if you can disassemble the LCD panel, so please try it!

: The iPhone 7 Plus is equipped with a 12 megapixel wide-angle camera with the same performance as the iPhone 6s/6s Plus, with only the number of pixels of the camera, plus a 12 megapixel telephoto camera, so in normal camera mode, It is now possible to shoot by switching between the two cameras according to the scene.
I will continue to disassemble the iPhone7 Plus 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, but if you lose it, you can remove it even if you use a stationery clip.
In that case, pay close attention and work at your own risk!

: Disassembly of the iPhone7Plus starts from the place where all the screws are removed like the iPhone up to now.
The screw of the red circle part is removed with the Torx screwdriver.

: since iPhone7 Plus is water resistant, a waterproof adhesive 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, you can work smoothly because the seal will be soft with heat if you use it, but if you do not, it will take time even with a hair dryer for home use, but substitutes are possible.

: The iPhone that has been released so far has been disassembled so as to cause the LCD from the home button side to the camera side, but this iPhone7Plus will open the book from left to right LCD panel.
First of all, the tool is inserted into the position where the spatula is located and it floats little by little, but it is easy to decompose when using a suction cup (orange sucker) together.
If you force yourself to force it, or put the spatula too far, the liquid crystal side will crack, or it will lead to other breakdowns, so we will slowly pay attention to floating the liquid crystal panel.

: If you float the liquid crystal even a little and make a gap, it will be easier to work if you insert a guitar pick etc. like the image.
By doing this, the liquid crystal will not close again!

: Next, open the left side of the LCD panel.
If you look closely at the inside of the floated part, you will see a black seal or a white seal, but it is a waterproof seal.Continue to work carefully

[iPhone7Plus Battery Replacement STEP 8]
: Next, the right side is floated, but there is a liquid crystal cable etc. on this side, so i carefully float the liquid crystal in the same manner as before so as not to damage it.

: There is a waterproof seal around the inside of the liquid crystal, but please note only the front camera part (upper part).
At this stage, I think that it was possible to float the left and right liquid crystal slightly, but the upper part does not decompose in the same way because the nail is caught inside, but you can slightly gap between the body and the liquid crystal when you slide the liquid crystal panel lightly in the direction of the arrow, When the waterproof seal comes into view, the seal is peeled off, and the liquid crystal panel can be raised from the left side to the right side.

: I was able to open the LCD panel as in the image.
I think that there are many people who have noticed, but in fact, this iPhone7 Plus is the one that has been submerged in the sea water, chips have corroded or the salt has hardened inside.We are disassembling for special cleaning and logic board repair investigation!
Since the cable connector on the liquid crystal side is connected to the logic board of the main computer infrastructure, let's work carefully so as not to break!

: After opening the LCD panel, the first step is to remove the battery connector from the logic board.
Because it is connected under the plate of iron which is in the image, all screws of the red circle part are removed.
Four screws of this part is not a normal + doiber, so please be sure to use a special tool because you can not remove it unless it is a special tool of the Y-shaped screwdriver!
If you work forcibly with a driver of a different shape, there is a risk of licking, so let's remove the special tool.

: I was able to remove the iron plate when I removed four screws and lifted them lightly.
Let's move on to the next process now that we know the structure of something!

: The red mark becomes the connector of the battery.
You can remove the battery connector from the logic board by using a plastic spatula or tool and lifting it from the bottom up.

: The battery of the iPhone7 Plus is fixed with a powerful double-sided tape to the body, but there is a black auxiliary tape that peels off the battery in the part that is enclosed in red frame.
It is possible to remove the battery easily by making good use of this part using a tool with a pointed tip such as tweezers.
First of all, please turn all the parts that are enclosed in red waku.

: If you pinch the black part that you just peeled off, the white seal will extend, but if you stretch it strongly suddenly, it will cut, so it will stretch slowly and carefully. If it breaks, heat is added from the back of the main body (apple mark side) with a dryer, etc., and it is necessary to insert plastic spatula on the side and under the battery so as not to damage other parts. It's easier to peel off the tape carefully than it is to do this, but in the end it doesn't matter which way. Carefully stretch the tape in the direction of the arrow.

: Slowly stretch the tape vertically, but if you can do it without cutting the tape until the end, you can remove the adhesive tape that secures the battery very easily.

: Only the battery was able to be removed from the iPhone7 Plus body.
iPhone7 Plus will still be a new model, so I do not think that there is a replacement in the deterioration of the battery.
Please refer to it at that time because it is necessary to remove the battery when performing decomposition cleaning repair by any chance such as submerged!
