Moto G30 screen replacement

Unclip the plastic back cover using any tool you like (mediators, sprudgers, Jimmy...)

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

Unplug both battery and display connectors (battery on the right and display in the middle). You can use the opening tool as lever.

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.

Unscrew the cover part at the bottom of the phone (USB connector side)

7 small Philips-head screws to remove, plus a bit of black adhesive tape

Once the cover is removed, unplug the flex cable

Detach the display flex cable from the back of the chassis

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.

Remove the glass shards still glued around the frame

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.

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

If you can read something like "22b8:XXXX Motorola PCS moto g(30)", congratulations: your motherboard still lives

Once your phone has been successfully torn down and tested, it is time to order the replacement screen

The part will cost you around 15-20€. You can find it here for instance

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