Disassembly/Repair of the mobile device Alcatel 1 SE 5030D (Alcatel One SE (2020) 5030D) with each step description and the required set of tools.
Step 2. Remove the tray
Use the ejection tool (aka Needle) or Paperclip. Push the tip all the way into the hole until the tray ejects, and then pull the tray of SIM and Memory card (Micro SD) out.
⚠️ Pay attention! The tool must be inserted into a hole on the edge of the phone's housing. Do not press too hard. It may break the tray eject mechanism.
Step 3. Open the back cover
Using a spudger or a plastic pick, carefully, around the edge, detach the back cover clips, and remove it.
Do not insert the tool deeply or bend it. Otherwise, the housing may be tampered with or damaged.
⚠️ Be careful when opening the cover from the volume and power buttons side. Thin cable and fragile buttons are straightforward to damage.
⚠️ Look in advance in the picture for the cables’ location for inter-board, touchscreen, display, buttons (if any) under the cover to not damage them accidentally.
Step 4. Unscrew the screws
Using a screwdriver (Phillips 1.5 mm PH000), unscrew 9 screws at the phone's upper part.
ℹ️️ Be sure to note the location of the screws before disassembling. When assembling the device, screwing the screw in the wrong place may damage the device or its part. To avoid damage, the removed screws and individual pieces (as gaskets or brackets) must be laid out in the appropriate order, or the screws and their holes in the phone must be marked with colored markers.
Step 5. Open the cover
Pry up the fingerprint sensor connector and remove the cover. On the cover stays a fingerprint sensor and an earpiece speaker tab.
Step 6. Disconnect the battery connector
Disconnect the battery connector as soon as possible.
ℹ️️ The Alcatel 1 SE (2020) 5030D model has a battery TLp038D7 with 4000 mAh capacity (aka rechargeable battery).
⚠️ It is highly recommended to disconnect the connector to avoid possible short circuits during disassembly. Also, try not to use a metal tool to disconnect the rechargeable battery connector or do it carefully.
Step 9. Disconnect the connectors
Disconnect the inter-board cable and coaxial cable connectors. Also, we pry off the microphone and vibration motor from the display frame.
⚠️ Be careful! Both are wired to the sub-board.

ℹ️️ The sub-board contains a charging port (Micro USB), wired microphone and vibration motor, spring contacts for the loudspeaker, and an antenna unit.

Pry up the connectors and remove three rear cameras and one front (selfie) camera.
Step 13. Disconnect the connectors
