12 steps

Turning off your Device
Turn your iPhone off completely to avoid damaging it during the repair. Press the standby button for about three seconds until the slider appears.
Wipe it from left to right. Now your iPhone will shut down completely, which can take about ten seconds.
Removing the enclosure screws
You need a pentalobe screwdriver to open the iPhone 6 Plus.

Remove the two pentalobe screws at the bottom of the enclosure. They are located to the right and left of the Lightning connector. Put the screws in the same container.
2 x 3.8 mm pentalobe screw
Lifting the display
Put your iPhone 6 Plus on a soft, clean surface to avoid scratching the back.

To lift the front panel, you need a suction cup and a hard plastic pick. If the screen is severely cracked, cover all of it with packing tape before you continue.

Place the suction cup over the Home button (if possible) or next to it (see figure 1). While lifting the screen with the suction cup, insert the hard plastic pick between the aluminum frame and the display frame and press down the aluminum frame. Also use the hard plastic pick to raise the screen (see figure 2). This usually takes several attempts.

As soon as you can lift the screen a few millimeters, you have to carefully work your way around the outside until it’s loosened on both sides (see figure 3).
Disconnecting the battery connector
Use a Phillips screwdriver to remove the Phillips screws on the battery connector (see figure 1). Then lift the cover (see figure 2). Put all the parts in the same container.
1 x 3.2 mm Phillips screw
1 x 2.3 mm Phillips screw

Now carefully lift the battery connector by inserting the pointed tip of the ESD spudger slightly below the connector (see figure 3). If you don’t have a spudger, you can also try using your fingernail.
Disconnecting the connectors
First remove the five Phillips screws from the silver cover (see figure 1). Put the screws in the same container. Then lift the cover to remove it.
1 x 1.6 mm Phillips screw
3 x 1.2 mm Phillips screw
1 x 2.9 mm Phillips screw

Disconnect the following four overlapping connectors (see figure 2) in the order shown below. Be very careful. Place the pointed tip of the spudger very slightly below the contact and lift it up.

Removing the battery
The battery is attached to the enclosure by three adhesive strips. Use the laboratory spatula to detach the three black ends of the adhesive strips from the battery (see figure 1).

Now pull off the adhesive strips very slowly. Hold the adhesive strips as flat as possible at the level of the iPhone. (See figures 2 and 3).

Now simply remove the battery.

Installing the battery
Attach new adhesive strips to the battery and pull off the film (see figures 1 to 3). Otherwise, the battery will have too much room and move around.

Now put the battery back in the iPhone and connect the connector (see figure 4). Pull the film off of the tabs and stick them securely to the battery (see figure 5).

Put on the silver cover and screw it in place (see figure 6).
1 x 3.2 mm Phillips screw
1 x 2.3 mm Phillips screw
Connecting the display
Reattach the connectors (see figure 1). Connecting the LCD connector generally takes a few tries. Be very careful to avoid bending the connector.

Touchscreen

Start your iPhone as soon as the connectors are securely attached. Check the function of the LCD, touchscreen, proximity sensor, front camera and earpiece.
If the connectors aren’t connected properly, stripes will appear on the display or parts of the touchscreen won’t work.

Now attach the cover and screw it in place (see figure 2).
1 x 1.6 mm Phillips screw
3 x 1.2 mm Phillips screw
1 x 2.9 mm Phillips screw
Installing the battery
Attach new adhesive strips below the battery. Otherwise, the battery will have too much room and move around

Now put the battery back in the iPhone and connect the connector (see figure 1).

Put on the silver cover and screw it in place (see figure 2).
1 x 3.2 mm Phillips screw
1 x 2.3 mm Phillips screw
Attaching the display
Then carefully fold down the screen. Make sure that the edge on the upper part of the screen where the cables are clicks into place properly. Now carefully push the screen on toward the Home button until it is properly installed in the frame.
Fastening the enclosure screws
Now screw in the two pentalobe screws at the bottom of the enclosure.
2 x 3.8 mm pentalobe screws
Setting the time
When the battery is removed from the device, the iPhone loses the time and sets itself to 1:00 a.m. on 1/1/1970. You could have trouble connecting to the cellular network if the time isn’t set.
After a repair, complete the following steps:

Synchronize your iPhone with iTunes or connect to a WLAN network and wait until the time is set.

Remove the SIM tray with the SIM card and reinsert it.

Activate airplane mode on the device and then deactivate airplane mode.
