Nokia 6 Motherboard Replacement

Introduction

Use this guide to replace your Nokia 6’s motherboard.

If the battery is swollen, take appropriate precautions. Be very careful when heating the phone when removing the screen. As the battery is in the center of the phone, avoid heating the center, focusing only on the edges to heat up the adhesive.

What you need

Step 2

If your display glass is cracked, take precaution by taping over the display to prevent further breakage and harm.
Lay overlapping strips of clear packing tape over the Nokia 6's display until the whole screen is covered.

Edit

Step 3

To soften the adhesive, use a heat gun and heat one edge of the phone for five minutes.
To use the heat gun, plug it into an outlet.
When the heat gun is plugged in, the heat gun automatically turns on and will start blowing hot air.

Step 4

Take a Jimmy and slide it under the glass after the adhesive has been softened.
Place a pick under the glass after lifting with the pry tool so that the screen won't re-adhere to the frame again.
Make sure to not touch the LCD edge underneath the glass layer with the metal pry tool or the cards. This can damage the ribbon cables underneath and compromise the structural integrity of the phone itself.
The corners of the screen are the most fragile part of the screen. Make sure that the entire edge of the screen is dislodged from the frame before prying at the corners.
