11 steps

Switch off the device
Turn off your device by holding down the power button on the back until the “Power off” option appears.
Tap to confirm and wait until the screen goes black.
Remove back cover
To loosen the back cover, use a heat gun or an ordinary hair dryer. Warm glue is easier to loosen, allowing you to remove the back cover.
The easiest way to loosen the back cover is to use a flat and flexible tool such as the iFlex.
We also recommend inserting flat picks to prevent the glue from sticking again.

Heat the entire rear glass. It's glued all around the edges and around the home button and over the USB port.

Insert the iFlex between the rear glass and the frame, but not more than 5 mm.

Be extra careful, the back cover can break very easily. Don't pry with the tool, but only slide it around the edges. If necessary, apply the heat several times and try again. Removing the back cover might take a while. Take a little more time and work carefully to make sure you don't break anything.

Once the rear glass comes off in one place, insert a pick into the gap to keep it open.

Then run the iFlexit around all the edges to gradually loosen the glue.

The rear glass has extra glue around the home button and over the USB port. Here you need to insert the iFlexit a little deeper. But not to far, or you could damage parts on the home button.
Once the rear glass is unglued, you can lift it off. There's not cable attached.
Remove speaker
4 × 2.7 mm Phillips

The LG G6 has only one screw length and only the midframe and speaker are screwed in.
Remove the equal-length Phillips screws from the speaker and store them for later.
Then pry out the speaker from the side of the battery and take it out of the device.
Remove midframe
7 × Phillips

Remove the equal-length Phillips screws from the midframe and store them for later.
Slide a flat, thin tool into the opening and pry out the midframe here.
The midframe is clipped into the device at 4 points. Carefully release it and take it out once it moves easily.
Disconnect the battery
Battery Connector

Disconnect the battery using a plastic tool to prevent short circuits.

Remove the battery
Don't bend the battery while removing it and don't heat it directly. If you need to soften the glue, heat the screen and not the battery. Don't heat the display to more than 60°C (140°F).The battery glue is not very strong.

Unstick the blue tab on the battery's lower edge.

Pull on the blue tab a little harder to remove the battery. If the battery is hard to unstick, you can heat the display to around 50-60°C to soften the glue.

Take the battery out of the device.
Insert battery
Place the battery in the device and press it on to make it stick.
Leave enough space on all sides when inserting the battery. Make sure the connector is placed over its socket, so you can plug it in easily.
Connect battery
Battery Connector

Put the battery connector on its socket and press it on carefully.
Insert midframe
7 × 2.7 mm Phillips

Place the midframe back in the device and press it in.
Fasten it using the Phillips screws.
Insert speaker
4 × 2.7 mm Phillips

Place the speaker in the device and carefully press it in.
Fasten the Phillips screws.
Attach rear glass
Place the rear glass back on the device and press it on.
You can heat the rear glass again to make the glue stick better.
