Guide format : Pdf Integrate

Step 1

Before proceeding to replace the power button cable of your Galaxy S7 you must, for evident safety reasons, turn off your phone.

To do this, hold down the off button for a few seconds, then confirm by selecting "turn off"

Step 2

Insert the SIM/micro SD card tray opening tool into the hole on the top edge of your phone, as seen above.

Then gently push the tool in.

Step 3

Next, take hold of the MicroSD/SIM card tray and remove it.

Step 4

Use a heat gun to start to soften the glue on the rear panel.

The glass rear panel is slightly curved and fixed well. If you use a hairdryer, pay particular attention to the corners of the glass. Don't hesitate to restart if you feel like it hasn't come unstuck.

Using the suction cup, lift the glass just enough to insert a opening pick between the frame and the rear panel.

Then, slide the opening pick around the entirety of the screen.

Step 5

Slide the opening pick around the entire rear panel to ensure it's completely unstuck and can be lifted.

Then start to lift the panel up.

Don't hesitate to heat the rear panel again if it doesn't lift off easily.

Step 6

Using a cross-headed screwdriver, unscrew the 12 screws that secure the internal frame of the phone, as seen circled in red above.

Step 7

Next, use the nylon spudger to pull up the top of the frame.

Step 8

Then lift, using the nylon spudger, the central section of the frame.

Step 9

Use the pointed end of the spudger to pull back the gold adhesive between the bottom part of the frame and the battery.

Step 10

Then, lift the bottom of the frame, all the while using the pointed end of the spudger.

Step 11

Next, unscrew the battery connector.

Step 12

In order to soften the glue underneath the battery, heat it for a few seconds with a hair dryer.

Then, with the flat edge of the spudger, lift up the battery.

Be careful to not heat the battery too much, as it can damage it.

Step 13

Unfix the battery by lifting its full length.

The battery of your Galaxy S7 is now removed.

Step 14

Use the pointed end of the nylon spudger to disconnect the small cable for the internal speaker.

Step 15

Then, with the iSesamo spudger, unfix the internal speaker from its place.

Step 16

The internal speaker of your Galaxy S7 is now removed.

Step 17

Using the nylon spudger, disconnect the front camera cable.

Step 18

Then take hold of the front camera and remove it using the metal tweezers.

Step 19

Disconnect the proximity sensor cable from the logic board.

Step 20

Now, unclip the cable for the volume buttons.

Step 21

Carefully disconnect the cable for the complete screen.

Step 22

Using the pointed end of the nylon spudger, proceed to disconnect the cable for the power button.

Step 23

Disconnect the GSM interconnect cable using the pointed end of the spudger.

Step 24

Repeat the step above to disconnect the WiFi/Bluetooth interconnect cable.

Step 25

Unscrew the connector for the home button from the logic board.

Step 26

Put the flat side of the nylon spudger underneath the logic board in order to lift it.

Step 27

Do not remove the logic board completely! It is still connected to the charging connector.

Unplug the connector in order to free the logic board.

Step 28

Dislodge the power button cable from its place, using the pointed end of the nylon spudger.

Step 29

The cable for the power button of your Galaxy S7 is now removed from the frame.

If the power button is temperamental, replace its cable with a new one.

To reassemble your Samsung Galaxy S7 follow this guide in reverse order.
