Huawei P40 lite Screen Replacement

1.Remove SIM Card Tray & Heat Back Cover:

• Insert a SIM ejector tool into the hole on the left side of the frame to eject and remove the SIM card tray.
• Apply heat to the edges of the back panel using a heat gun or heating pad (approx. 80°C for 2–3 minutes) to soften the perimeter adhesive.

2.Pry Open Back Panel (Safety Warning):Watch out for the side fingerprint sensor flex cable!.

• Insert an opening pick under the lower edge of the back cover.
• Slowly slice through the adhesive along the edges.

CRITICAL WARNING: Do not insert the opening pick deeper than 3–4 mm. The fingerprint sensor / power button flex cable is located on the right edge of the device. Inserting the tool too far will slice this cable.

• Carefully lift off the back panel once the adhesive is fully severed.

3.Remove Motherboard Shield & Disconnect Battery:

• Unscrew the 9 Phillips (PH000) screws securing the top plastic motherboard bracket.
• Insert a spudger or opening pick under the plastic bracket notch and gently pry upward to unclip it from the frame.
• Disconnect the Battery: Use a nylon spudger to pry up the battery press-connector immediately.

IMPORTANT: Always disconnect the battery power before touching the screen connector to prevent electrical shorts or blowing the backlight circuit on the motherboard.

4.Disconnect Display & Remove Battery:

• Disconnect the display flex cable connector located adjacent to the battery connector.
• Follow the pull-tab directions printed on the battery sleeve: lift tab 1, peel back tab 2, and pull tab 3 firmly upward to detach the battery from the frame bracket.

5.Heat & Separate the Display Panel:

• Apply heat across the front display glass (approx. 80°C for 3–5 minutes) to soften the frame adhesive.
• Insert a thin opening pick into the gap between the glass screen and the outer plastic frame.
• Carefully slice around all four edges of the screen, keeping the pick depth under 3–4 mm to prevent damaging the LCD digitizer layers.
• Unfeed the display flex cable through the slot in the midframe behind the battery area and lift the display completely off the chassis.
