How to Replace the Screen on Your Xiaomi Redmi Note 11 & Note 11S: A Complete DIY Guide
Published on July 13, 2026 | Category: Tech Repair & DIY | Reading Time: 5 mins
Cracking your smartphone screen can feel like a disaster, but it does not have to mean a costly trip to a professional repair center. If you own a Xiaomi Redmi Note 11 (4G) or a Redmi Note 11S (identifiable internally by its BN5D battery), replacing the screen is entirely achievable at home with the right tools, a bit of patience, and a steady hand.
In this robust, step-by-step repair guide, we will walk you through the process of safely dismantling your phone and installing a fresh display assembly, saving you money while breathing new life into your device.
⚠️ CRITICAL SAFETY WARNING: Before starting, drain your smartphone battery below 25%. A charged lithium-ion polymer battery (like the 5000mAh BN5D) can catch fire or explode if accidentally punctured during repair. Always wear protective eye gear when handling cracked glass.
Essential Tools You Will Need
Ensure your workspace is clean, flat, and well-lit. Gather the following repair tools before heating up your phone:
- A replacement screen assembly (with or without the frame)
- A precision Phillips screwdriver (#00)
- A heat gun, hair dryer, or a microwaveable heat pack (iOpener)
- Plastic pry tools, spudgers, and guitar picks
- A suction cup
- Precision tweezers
- High-quality electronics adhesive (such as B-7000 or T-7000) or pre-cut adhesive tape
Step-by-Step Replacement Procedure
Step 1: Soften the Back Cover Adhesive
Power off your phone completely and remove the SIM card tray. Use your heat source to apply gentle heat to the outer edges of the back cover for about 2 to 3 minutes. This softens the adhesive sealing the plastic back plate to the midframe.
Step 2: Remove the Back Plate
Apply a suction cup to the lower half of the back cover. Pull up gently to create a small gap, then insert a thin plastic opening pick. Carefully slide the pick around the entire perimeter of the phone to slice through the adhesive. Lift the back cover off slowly and set it aside.
Step 3: Unscrew the Midframe
Use your Phillips screwdriver to remove all the screws securing the plastic motherboard shield and the bottom speaker module. Keep these screws organized—they are vital for reassembly! Once unfastened, gently pry away the plastic sub-frame to expose the internal components.
💡 PRO-TIP: Immediately disconnect the orange battery flex cable (connected to the BN5D battery) using a plastic spudger. This cuts all electrical currents to the logic board and prevents short circuits while you handle the display connection.
Step 4: Disconnect the Screen Flex Cable
Locate the display flex cable running over the battery assembly. Carefully disconnect it using your non-conductive plastic pry tool.
Step 5: Heat and Remove the Damaged Screen
Flip the phone over. Apply heat to the front glass for 3 to 4 minutes to loosen the screen's strong bezel adhesive. Use your suction cup and a thin metal opening tool to wedge into the seam. Work your way around with plastic picks, taking extreme caution not to damage the underlying frame if you are reusing it.
Step 6: Clean the Frame and Test the New Screen
Before gluing the new screen down, scrape off any leftover adhesive and glass fragments from the frame. Do not skip this step! Connect the new screen's flex cable and temporarily reconnect the battery to run a "dry test." Power the phone on to check touch responsiveness, brightness, and colors. If it works perfectly, power it down and disconnect the battery again.
Step 7: Apply Adhesive and Set the New Screen
Apply a thin, even bead of B-7000 adhesive around the inner bezel of the frame. Thread the new screen's flex cable through the frame and seat the display firmly. Apply light pressure around the edges, and use rubber bands or plastic clamps to hold the screen in place for at least 30 to 60 minutes.
Step 8: Final Reassembly
Once the adhesive has cured, reconnect the screen flex, lock down the BN5D battery connection, screw the motherboard shield back on, and glue the back cover back in place. Your Redmi Note 11 is now as good as new!
Conclusion
Completing a screen replacement on a Xiaomi Redmi Note 11S or Note 11 might feel intimidating at first, but taking it step-by-step ensures a seamless, highly rewarding experience. You have successfully bypassed expensive repair fees and mastered a valuable tech skill!
