Huawei Y300 LCD Screen Replacement

Introduction

In this guide we are going to replace the LCD display on the Huawei ascend Y300 android smartphone. This may be necessary for a damaged screen causing lines, dark spots, and distorted images. The damage may be caused by:

Physical impacts/pressure
Heat
Moisture
Dust

Before we start it is a good idea to prepare an organized area and a bowl or tray to put the small screws in and prevent them getting lost to carry out the repair.

Use a screwdriver (T4 if you are using the 54 bit driver kit) to remove the 8 screws along the edges of the phone. There are four in each corner and four in the middle on the sides.
Put the screws on the magnetic mat/parts tray or bowl to make sure they are not lost.

On the left of the motherboard there is a ribbon cable that connects the volume rocker to the motherboard, we need to disconnect it.
To do this, using either the spudger or tweezers lift up the retention flap holding the cable down.
Next using the tweezers carefully pull the ribbon cable away from the socket it was in until it is completely clear of the connector.

Edit

Step 6

There are two more ribbon cables at the top that must also be disconnected, to do this simply lift them up from their connecter with the tweezers or with the spudger.

Edit

it's important to add that lateral flat cable can be lift up only after turning up the rotating switch which is on the lower side.
