Introduzione

This guide shows how to disassemble and transfer the internal components of a LG K92 to a replacement display with a frame preinstalled. The parts used are a replacement screen installed into a frame, this is the most cost effective method, using just the display without a frame is not advised.

Passo 1

Heat the plastic back panel with a heatgun or heating pad.
Use a thin metal pry tool or razor to separate the adhesive from the frame, and peel the back cover off.

Passo 2

Remove 11 same-sized phillips screws from the top antenna panel.
Using tweezers, forcefully pop the panel from a safe area up and out of the housing, the lower middle screw hole is a good area to apply leverage.

Passo 3

Remove 8 more identically sized phillips screws from the lower antenna and speaker panel.
Pop the lower panel off with tweezers, it should come off relatively easier than the previous panel.

Passo 4

Disconnect the battery first!
Then disconnect the other main lego style connectors and ribbons. There is no need to disconnect the cameras.

What cable sources what? There are 3 battery cables? One in the bottom and the 2 cables on the right? Nothing is explained very well in this guide.

This guide is for disassembling the device, not an in depth explanation. From left to right: power button, battery, LCD ribbon, charging port ribbon, NFC coil ribbon.

At no place did this guide instruct to remove the SIM/Memory card . I did not think of it and broke the tray that hold them trying to pry out the the main logic board in the next step. It was not obvious that that was what was preventing me from getting the board out until It broke.

I will add that this guide was a godsend otherwise.

Passo 5

Remove the main logic board by pulling from the top and lifting it out.

Passo 6

Remove the single Phillips screw from the charging daughterboard, and pull it out of the frame.
(Optional) Leave the antenna lines connected to reduce risk of breaking them.

Passo 7

The power button has a small pressure connected ribbon that is adhered to the frame, carefully pry it up.
The fingerprint reader itself is on a separate lego style connector that can then be fished out.

Passo 8

Gently pull the pressure connection pad up from the frame, then work the ribbon out from the trench.

Passo 9

Using tweezers or a bent pry tool, push the buttons out from inside of the frame.

Passo 10

Some small components like the vibration motor, antenna sticker, or earspeaker may need to be moved to the new frame.

Passo 11

Use a heating pad to warm the device from the front, apply generous amounts of alcohol to the battery compartment and carefully lift it out.
Avoid bending the battery as this can compromise the internal cells.

Passo 12

Remove protective plastics from the replacement frame.
Reinstall components in the order in which they were removed. Be sure to align the antenna wires carefully to prevent pinching issues.

Passo 13

Reinstall remaining components and tighten screws in their respective locations.
Always test the device prior to sealing the back panel on with new adhesive.
