    • Slighly move the back cover in order to unscrew the plastic piece behind it

    • You will find 9 small Philips-head screws

    • You will also have to remove small black adhesive pieces to be able to remove the part completely

    • Once the black plastic cover piece is removed, it is possible to unplug the cable holding the back panel

    • Once this flex cable unplugged, lift the back panel completely

  4. Moto G30 screen replacement, Unplug battery and screen: step 5, image 1 of 1
    • Unplug both battery and display connectors (battery on the right and display in the middle). You can use the opening tool as lever.

  5. Moto G30 screen replacement, Unglue the battery: step 6, image 1 of 1
    • Very carefully unglue the battery

    • Adhesive is quite strong here, and the battery is not very rigid, so this is a complicated operation. It would be dangerous to head the battery cell, be patient and careful.

    • Once the battery is gone, it is possible to add some heat to help detach the screen

    • I could not properly unglue with a cutter blade on the side. My technique is simpler and more brutal: I pushed the display away from the connector hole, with a rigid tool.

    • Replug the battery pack

    • Test battery voltage on the testpoint at the left of the connector (you will find ground anywhere on the metal chassis). Voltage must be between 3.6 and 4.2 V.

    • You can also test the motherboard with a Linux-based computer

    • Unglue the screen-USB-motherboard flex cable from your broken screen, and replug the bottom USB board with the top motherboard

    • Turn on phone with Power On + Up buttons

    • Plug it to the computer with an USB-C cable

    • Type "lsusb" in a shell

    • While waiting for your order, don’t forget to store your parts and small screw properly
