Xiaomi Redmi Note 11 Disassembly Guide (How to Open and Service)
We detail the necessary heat application, proper separation techniques, and critical connection points to prevent damage to flex cables and camera modules during common service operations like battery or screen replacement.
⚠️ Warning and Pre-Service Safety Protocol
Servicing the Xiaomi Redmi Note 11 involves delicate work with heat and fragile components. This process should only be attempted by qualified professionals.
- Data Integrity: Although disassembly doesn't affect software, ensure the device is fully backed up.
- Power Down: The device must be completely powered off before applying heat or opening the back cover.
- ESD Protection: Always utilize an Anti-Static Mat and an ESD Wrist Strap to protect the sensitive internal circuit board components.
- SIM Tray Removal: Crucial Step: Use a SIM ejector pin to remove the SIM/MicroSD card tray entirely. Failure to do so will result in immediate damage to the mid-frame upon opening.
Tools Required:
- Heat Gun or Heating Pad (Recommended temperature: $80^\circ\text{C}$).
- Fine Metal Pry Tool (for initial insertion).
- Plastic Opening Tools / Cards (for safe separation).
- Phillips Screwdriver (PH00).
- Fine Tip Tweezers.
- Suction Cup (optional).
Section 1: Back Cover Separation (The Critical First Step)
The Redmi Note 11 utilizes a plastic back cover secured with strong adhesive.- Heat Application: Place the phone on a heating pad or apply a heat gun evenly around the perimeter of the back cover for 1-2 minutes at approximately $80^\circ\text{C}$ to soften the adhesive.
- Initial Insertion: Place a suction cup on the back cover near the bottom. Gently pull up while inserting a very thin metal opening tool or a sharp, plastic pry tool into the seam, typically starting from the bottom edge near the charging port.
- Use Plastic Tools: Once a small gap is created, immediately switch to plastic opening tools or cards. Slide the plastic tool slowly around the edges, focusing on cutting the adhesive and gently releasing the internal plastic clips.
- Full Separation: Work slowly around all four sides. Avoid applying excessive force near the volume and power buttons, as the flexible circuits for these buttons are delicate.
Section 2: Internal Shielding and Battery Disconnection
After the back cover is removed, the priority shifts to safety.

- Remove Mid-Frame Screws: Use the PH00 screwdriver to remove all visible screws securing the black plastic shields covering the motherboard and the battery connector. Keep screws organized as they may have different lengths.
- Disconnect the Battery: Locate the main battery flex connector (BATT). Using a plastic spudger, gently lift the connector straight up from its socket. This is the first and most vital step to prevent a short circuit during the remainder of the repair.
- Disconnect Flex Cables: Disconnect the main display flex cable and the sub-board interconnect cable, which usually run beneath the battery and shield plates.
Section 3: Motherboard and Component Removal
- Main Board Screws: Remove any remaining screws securing the motherboard itself.
- Coaxial Cables: Carefully disconnect the antenna coaxial cables using tweezers.
- Motherboard Lift: Gently lift the main board out of the chassis. Be careful of the camera module, which may be lightly stuck to the frame.
- Battery Removal (Advanced Step): The battery is secured with strong pull-tabs (if present) or powerful adhesive. If using pull-tabs, pull them slowly and horizontally. If no tabs are available, apply heat to the front side of the screen or the backside of the battery area and use a specialized flat tool to gently pry the battery out, working cautiously to avoid puncture.
