Essential Phone Motherboard Replacement

Introdução

This guide explains the process behind removing and replacing the Essential PH-1 phone’s motherboard and the tools needed to do so.

The motherboard is a central component necessary to the functioning of the phone that allows the CPU, RAM, and other hardware elements to communicate with each other. If your Essential Phone overheats while making calls, charging, or won’t turn on altogether, the motherboard may be damaged. Note that replacement motherboards for the Essential Phone may be hard to find.

    • Power your phone off before you begin.

    • If possible, drain the battery before disassembly. When the battery is charged, there's increased risk of a dangerous thermal event if the battery is overheated or damaged during repairs.

    • If your display is cracked, completely cover it with packing tape to contain the glass shards and avoid injury.

    • Heat the perimeter of the display to soften the adhesive securing it.

    • If available, use a hot plate or heat pad. Place the Essential Phone face-down and heat it to 85° C for at least 15 minutes.

    • Otherwise, use a heat gun to evenly heat the entire perimeter of the display until it's too hot to touch. Try to maintain a high temperature for 15-20 minutes—but beware that without exact control over the temperature, you can easily destroy the display.

    • Wear heat-resistant anti-static gloves as needed to safely handle the phone after this step.

    • In the following steps, you will separate the display panel and cover glass assembly from the Essential Phone's chassis.

    • For reference, the back of the display panel is shown at left. Note the contours of the display panel. Tools can only safely be inserted into the camera notch at the top, and along the very thin (just over 1 mm) black bezel surrounding the display.

    • Inserting tools at any other location risks permanent damage to the LCD.

    • While the phone is still hot, apply a heavy-duty suction cup to the top half of the display.

    • After positioning the suction cup, gently press down, and then close the handle to securely fasten the suction cup to the display surface.

    • If your display is badly cracked, the suction cup may not adhere. Skip the next step below and use your blade to slice under the display as best you can.

    • Pull on the suction cup handle to open a slight gap between the top edge of the display and the Essential Phone's titanium enclosure.

    • You only need a very slight gap, but this may require a significant amount of force. If you're having trouble, apply more heat and try again.

    • Insert a thin blade or pry tool into the camera notch at the top of the display.

    • The gap where you can safely insert a tool is only about 5 mm wide. If you hit the LCD with your tool, you will damage it.

    • Use your suction cup and blade or pry tool to widen the gap at the top of the display until you can insert a second tool under the glass, closer to the corner.

    • Insert a halberd spudger no more than 1 mm under the display, and cut the adhesive all along the top edge.

    • The bezel surrounding the LCD panel is slightly over 1 mm deep. If you insert your tool any deeper, you can damage the display.

    • Continue carefully separating the adhesive at the top corners and down both sides of the display.

    • Do not insert your tool more than 1 mm.

    • Do not pry or slice on the bottom edge yet. The display's FPC is folded under the bottom edge and may be damaged.

    • Pull carefully on the suction cup to swing the top edge of the display away from the chassis.

    • Swing the display open to about 90° and prop it up against something sturdy so it doesn't move while you work.

    • Carefully slide a pick underneath the display cable to separate the adhesive securing it to the metal shield beneath.

    • If necessary, add a little heat to soften the adhesive and make it easier to separate.

    • The two adhesive pads securing the display cable are conductive and should be firmly re-adhered during assembly. If necessary, replace the pads.
