12 steps

Removing the back cover
The back of the Samsung Galaxy S6’s enclosure is glued firmly in place. To detach it, you have to constantly heat it with a heat gun so the glue will soften. Then you have to insert a plastic pick into the gap between the frame and the glass to detach the adhesive.

The gap between the aluminum frame and the glass is very small. We recommend that you use a very flat, sturdy object to get between them.

Carefully lift the back cover while using a suction cup.

As soon as a little gap opens up, use the plastic pick to avoid damaging the aluminum.
Inserting the pick
You should only insert the pick a few millimeters between the back cover and the frame to prevent damage inside the enclosure.

The back cover is glued to the entire outer edge of the Galaxy S6. Move the pick once around the entire phone.
The back cover is painted on the inside. Remove any adhesive residue carefully to avoid scratches or cracks.

Once you’ve detached all the glue, you can carefully lift the back cover.
Removing the midframe
Remove the 13 Phillips screws that hold the plastic cover in place.
13 x 3.3 mm Phillips screws

Take out the SIM card tray.

Now lift the charging pad for wireless charging. It’s lightly glued to the midframe.

In order to remove the midframe, you have to carefully push down the battery and the rest of the smartphone. Use your other hand to push up the frame. If it doesn’t move, carefully insert a pick between the display and the frame, and press it upward.
Removing the front camera
Place the pointed tip of the spudger very slightly below the contact and lift it up. Make sure you don’t break off the resistors that are soldered onto the logic board.

Now you can disconnect the front camera connector. Be very careful.
Removing the logic board
Disconnect the following contacts. Place the flat end of the spudger very slightly below the contacts and lift them up.
Battery
Display
Earpiece
Home button
Two antenna connectors

Now you can lift the logic board at the level of the back camera and fold it to one side.
The back of the logic board is still connected to the dock connector.

There's a small plastic pin in the opening of the SIM tray. Make sure it doesn't fall out.
Disconnecting the dock connector cable
Once the logic board is folded over, you can use the spudger to disconnect the connection.

Removing the battery
The battery is glued to the enclosure. Heat the battery slightly to soften the glue below it.

Lift the battery one millimeter at a time using the spudger or a plastic pick.

Heat the battery at regular intervals so the glue stays soft and doesn’t stick.

Work very slowly and carefully because the tool could damage the battery and cause fluid to come out.
Installing the battery
Now put in the battery. Make sure it’s aligned correctly.

Make sure the Home button cable isn’t under the battery.

Press it gently onto the adhesive strips.
Installing the logic board
Now connect the dock connector to the logic board again.

Fold it over and put it in the frame.

Make sure the cables don’t get under the logic board. Use the picture to check whether your logic board is positioned correctly.

Now reconnect all the connectors:
Battery
Display
Earpiece
Home button
Antenna connectors
Installing the front camera
Now put the front camera in the original location.

Then connect the connector to the logic board.
Connecting the frame components
Attach the outer frame to the main component again. Start at the dock connector and firmly press the two frame components together.

Then screw them together.
13 x 3.3 mm Phillips screws
Attaching the back cover
As a last step, you have to attach the back cover again.

The old glue is usually still sticky enough.

Put the back cover back on, heat it slightly and then use a little force to press it onto the smartphone for a while.
