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.

Using a screwdriver (precision star-shaped 0.8 mm aka Pentalobe), unscrew/drive 2 screws out at the end of the phone.

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.

Disconnect the battery connector as soon as possible. It is better to use a non-metal or plastic tool to avoid any damage.

ℹ️ The Xiaomi Mi 5X model has a battery BN31 with 3000 mAh capacity (aka rechargeable battery).

Using a screwdriver (Phillips 1.5 mm PH #000), unscrew the six screws.

Pry over the edge and remove the assembly with a loudspeaker and vibration motor.

Disconnect the coaxial cable connector, inter-board cable connector.

⚠️ Do not pull on the cable or pry it with a sharp tool, the connectors are pretty weak and break easily, or the cable falls out of the end (lug).

ℹ️ The sub-board contains a charging port (Micro-USB), microphone, headphone jack, spring contacts for the speaker, and an antenna unit.
