This guide provides a structured explanation of how to disassemble the Xiaomi Redmi 9T while minimizing risks.

⚠️ Important Safety Notice

Before attempting any disassembly on the Redmi 9T, you must consider the following risks:
  • The back cover is firmly glued and may snap if lifted aggressively.
  • Excess heat can affect the LCD panel or loosen internal solder joints.
  • Internal ribbons and connectors can tear easily if pulled without precision.
  • Sharp metal tools may damage the battery or scratch the mainboard.
  • Opening the phone immediately voids the manufacturer warranty.
  • Mishandling the battery may cause swelling or short circuits.

🛠️ Redmi 9T Disassembly Procedure — Step by Step

1. Required Tools

Have the following tools ready:
  • Heating pad or heat gun
  • Thin plastic opening cards
  • Plastic pry tool
  • Nylon spudger
  • Small Phillips screwdriver
  • Anti-static mat or gloves
Avoid metal blades near the battery area to prevent puncture hazards.

2. Softening the Adhesive

Start by warming the back panel for around 90 seconds:
  • Apply the heat around the edges only.
  • Avoid prolonged heating over the camera region.
  • The objective is to soften the adhesive—not to overheat the entire frame.

3. Creating the Initial Opening Point

After applying heat:
  1. Attach a suction cup at the bottom section of the back cover.
  2. Gently lift to form a narrow gap.
  3. Insert a plastic card into the gap and slide slightly to widen it.
  4. Use slow, consistent motion to avoid cracking the plastic.

4. Separating the Back Cover

Move the opening card around the frame to gradually separate the adhesive:
  • Begin from the bottom and work your way around the left and right sides.
  • Reapply light heat if resistance increases.
  • Continue until the cover is free and lifts off smoothly.
The Redmi 9T back cover typically does not have attached flex cables, but it is always wise to lift slowly and inspect the inside before removing the cover completely.

5. Removing the Inner Protective Frame

Inside the device:
  • Unscrew all visible Phillips screws holding the protective plastic shield.
  • Detach the plastic frame carefully—it also holds the camera and battery connectors underneath.
  • Disconnect the battery first to eliminate the risk of electrical damage.

6. Accessing Internal Hardware

Once the protective shell is removed, you can access:
  • The main motherboard
  • The rear camera array
  • The sub-board (charging board)
  • The loudspeaker module
  • The vibration motor
  • Battery adhesive pull tabs for removal
Always detach flex cables gently and avoid bending the board excessively.
