Introduction

This guide will show you how to remove the motherboard of your Moto G 3rd Generation. Follow these step for access into the phone's interior. The disassembly requires the use of a heat gun or an iOpener.

  1. Use your fingernail to pry under the notch on the bottom of the phone and remove the back cover. Make sure to fully power off the phone before you begin disassembly.

  2. Use a heat gun or an iOpener as a heating tool. This guide explains how to use the iOpener. Evenly apply heat to the edges of the touchscreen to loosen the adhesive.  Continue to Step 3 once the edge of the screen is warm to the touch.

    • Evenly apply heat to the edges of the touchscreen to loosen the adhesive. Continue to Step 3 once the edge of the screen is warm to the touch.

    • Do not let the iOpener/heat gun remain on one spot for too long. Excess heat can damage the phone.

    • When reassembling the phone, use the iOpener/heat gun to help the adhesive fuse to the new screen. Heat the screen edges, apply pressure to the screen, and hold the screen in place until it is secure.

    I kept my phone on the radiator for 10min and loosened it enough to open (felt safer than a heat gun).

  3. As the adhesive loosens, pry up an edge of the screen with a plastic opening tool or an opening pick.  A suction cup may also be useful here. Use an opening pick to hold that edge in place and continue this process around the entire screen, applying more heat as necessary. Avoid damaging the LCD screen connector while prying along the screen edges.  It is located on the left edge of the phone, across from the volume controls.

    • During reassembly, new adhesive may need to be applied over the old adhesive to properly secure the screen.

    You may need to remove the mouthpiece and earpiece gauzes from the screen to fit to the replacement screen

    Be careful not to damage the adhesive tape on the old screen as you may need to reuse it along with the two gauzes on the replacement screen

    which adhesive tape?

    What width of adhesive is appropriate to buy to replace the existing one? I can see 1mm, 2mm etc for sale

    The width of the adhesive tape that goes around the rim is 2mm. But rather than buying generic 2mm tape, which won't seal well at the corners because it would be bent pretty sharply, it's best to get a precut adhesive that is made for this specific phone and that comes with the corners (and everything else) already pre-shaped: it's cut into a phone-shaped sheet, most of which you'll be discarding. Such sheets are available on ebay.

    I did not need to use any new adhesive strips to get my screen securely back in place. After placing the screen back, just heat the edges of the phone as before and press tightly (though not too hard, of course) until cooled.

    • Use a plastic opening tool to flip up the lock on the display cable ZIF connector.

    • Pull the display cable from its socket on the motherboard.

    • When installing a new display, carefully remove all remaining adhesive from the phone, and clean the adhered areas with isopropyl alcohol (90% or greater) and a lint-free cloth. Install the display using pre-cut adhesive or a strong double-sided tape such as Tesa 61395. Turn your phone on and test your repair before sealing the display in place.

    This part was actually the trickiest of the whole (replacing battery) process. Putting it back together here is tough… well would have been better had I not left my glasses in work.

    • Carefully lift the right edge of the motherboard from the phone.

    • Avoid pulling on the battery wires, which connect the left underside of the motherboard to the battery.

    When taken battery out I took it out wrong and now the new battery plugging into old area is not possible is there a repair part where the battery connects to the logic board Mahalo.
