Disassembly/Repair of the mobile device Alcatel 3C 5026D with each step description and the required set of tools.

⚠️ Before disassembling, do not forget to turn your phone off.

Use the Key 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.

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.

⚠️ Pay attention to the fingerprint sensor glued to the back cover from the inside.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew two screws and remove the bracket holding the connectors.

Disconnect the battery connector as soon as possible.
