Einleitung

If your LG G8 ThinQ’s screen is experiencing symptoms described in our troubleshooting page such as dead pixels or irregular touch response, this guide will help to replace the screen and access some functions and/or displays that may be obsolete with a damaged screen.

The LG G8 ThinQ requires disassembly of the entire interior of the device to completely replace the screen.

Before disassembling your device, discharge the battery below 25%.

This phone uses a strong adhesive on the battery and back panel; iFixit’s adhesive remover or high concentration (90% or higher) isopropyl alcohol can be used to make the process easier.

Adhesive can be replaced to closer replicate factory fit and finish.

Werkzeuge

Schritt 1

Unplug and power off your phone before you begin.
Insert the SIM card eject tool into the pinhole in the lower right side of the phone.
Remove the SIM card and tray.

Schritt 2

Place the phone so that the screen is facing down.
Insert opening cards between the back panel and frame of the phone to loosen the clips and adhesive.
Using equal pressure, carefully pry the back panel away from the phone.
Once enough space has been created, use an opening tool to completely separate the back panel from the phone.

This is where I started to ponder for the first time because my camera looks different.

I also have a LG G8 ThinQ but maybe the european version

Schritt 8

Flip phone so that screen is facing up.

The adhesive can be difficult to soften; it may take many attempts.

the battery type of my LG is "BL-T43"

Schritt 10

Using opening cards or an opening tool, carefully pry around the edges of the battery.
If you have trouble prying up the battery, the adhesive may not be loose enough. Re-apply heat, or use some isopropyl alcohol under the battery, allowing it to penetrate for several minutes to weaken the adhesive.
Remove the battery from the phone.

Although it is a different phone, the instructions were helpful.

Unfortunately, my battery exchange was pointless.

I think my USB socket is defective and unfortunately I can't find any instructions for it at the moment.

But if anybody want, i can send a few pics from the repairing

I did not do this myself, but I now see the labor involved, in addition to the rarity of LG phones. Meaning, I understand why it costs what it does for a professional to do this.

Hi. I had my screen replaced a few months back. It was repaired by a friend who has been working in the repair industry for most of the past decade. However, the under screen fingerprint scanner no long functions. What is causing this, and how can I fix it? Thanks
