12 steps

Removing the enclosure screws
Depending on when your iPhone was manufactured, you’ll need either a Phillips screwdriver or a pentalobe screwdriver to open your phone.

Depending on when your iPhone was manufactured, you’ll need either a Phillips screwdriver or a pentalobe screwdriver to open your phone. They are located to the right and left of the dock connector. Put the screws in the same compartment of your organizer tray.
2 x 3.6 mm pentalobe/Phillips screws
Removing the back cover
Use your thumbs or the palm of your hand to push the back cover of your iPhone about 4 mm away from the bottom of the phone where the dock connector is (see figure 1).

Then you can lift the back cover at the end that’s sticking out past the phone (see figure 2).
Disconnecting the battery connector
If your iPhone’s still on, turn it off now by holding down the standby button for about five seconds and following the prompt on the display.

Remove the screw on the battery connector using a Phillips screwdriver (see figure 1). Put the screw in a separate compartment of your organizer tray.
1 x 2.6 mm Phillips screw
The battery contact point on the logic board could come off. If the contact point breaks off but the soldering points are still intact, you can solder the contact point back on.

Now carefully lift off the battery connector by inserting the pointed ESD spudger slightly below the silver cover plate (see figure 2). If you don’t have a spudger, you can also try using your fingernail.

For the rest of the repair, you can also use the metal laboratory spatula instead of the spudger. This may make some steps easier for you. However, we explicitly recommend using the ESD spudger produced specifically for precision electronics.
Removing the battery
The antenna cover is under the battery connector. NRemove the cover and put it in the same compartment of your organizer tray as the Phillips screw you removed before. (See figure 1).

Now remove the battery. It’s sometimes glued firmly in place. Insert the flat end of the spudger into the space (about 1 cm to the left of the volume down button) between the battery and the outer frame, and slowly lift the battery (see figure 2). If the battery’s really stuck on, use other leverage points to the right and left of the original spot to pry it off. If you still can’t detach the battery, you can use a heat gun to warm it slightly from the outside and soften the glue.

Now you can also disconnect the antenna connector by carefully pulling it off the plug head using the spudger (see figure 3).
Removing the Wi-Fi cover
Remove the five Phillips screws. (See figure 1).
1 x 2.3 mm Phillips screw
2 x 1.6 mm Phillips screws
1 x 4.8 mm Phillips Wi-Fi screw
1 x 1.3 mm Phillips screw

Use the flat end of the spudger to detach the cover. (See figure 2).

Lift the cover out of the phone. Note that the cover is hooked on in two places. (See figure 3).
Removing the rear camera
Now disconnect the LCD and touchscreen connectors. Be very careful (see figure 1).

Then lift off the camera connector and remove the camera (see figure 2).

Installing the rear camera

Reconnect the two other connectors (see figure 2).

Installing the Wi-Fi cover
Put the cover on the logic board and make sure it’s hooked on properly.

Then fasten it with the five Phillips screws (see figure 1).
1 x 2.3 mm Phillips screw
2 x 1.6 mm Phillips screws
1 x 4.8 mm Phillips Wi-Fi screw
1 x 1.3 mm Phillips screw

If you have problems with the Wi-Fi signal later, the Wi-Fi screw may be screwed in wrong. Also check whether the Wi-Fi contact point is fitted properly on the cover (see figure 2).
Installing the battery
Now put the battery back in the iPhone.

Then install the antenna cover (see figure 1).

Now click the battery connector back into place and screw it in (see figure 2).
1 x 2.6 mm Phillips screw
Attaching the back cover
Put the back cover back on and carefully push it the last few millimeters toward the dock connector.
Fastening the enclosure screws
Now screw in the two screws at the bottom of the enclosure.

Then all you have to do is push in the SIM card tray.
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.
