🔧 Repair Overview
Charging Port Repair is one of the most common repairs for Redmi Note 12 Pro. This repair involves replacing the damaged connectivity component with a new or refurbished part. The process typically takes 30 min - 1 hour and requires easy skill level.
What You'll Need
- Replacement connectivity part (OEM or aftermarket)
- Precision screwdriver set (Phillips #000 or pentalobe)
- Opening tools (plastic spudger, suction cup)
- Adhesive strips or glue
- Clean workspace with good lighting
Step-by-Step Process
Step 1: Eject the SIM card tray
Insert a SIM card eject tool, a SIM eject bit, or a straightened paper clip into the hole on the SIM tray located at the left edge of the phone.
Press directly into the hole to eject the SIM card tray.
Remove the SIM card tray.
Step 2: Heat the rear glass
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.
Step 3: Secure a suction handle
If the rear glass is cracked, the suction handle may not stick. Try [https://d3nevzfk7ii3be.cloudfront.net/igi/4MmKE22Cy2MavVZU|lifting it with strong tape|new_window=true], or superglue the suction handle in place and allow it to cure so you can proceed.
The surface of the rear glass is not completely smooth. For a better grip of the suction handle, apply tape to the rear glass or moisten the suction handle.
Secure a suction handle to the right edge of the rear glass, as close to the edge as possible.
Step 4: Create a gap
Lift the rear glass with the suction handle to create a small gap between the rear glass and the frame.
In case you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the [https://www.ifixit.com/Guide/iOpener+Heating/25705|iOpener|new_window=true] instructions to avoid overheating.
Insert an opening pick into the gap you created.
Step 5: Slice the adhesive
Slide the opening pick to the top right corner to slice the adhesive.
Leave the opening pick in place to prevent the adhesive from resealing.
Step 6: Slice the adhesive
Insert a second opening pick next to the top right corner.
Slide the opening pick to the bottom right corner to slice the adhesive.
Leave the opening picks in place to prevent the adhesive from resealing.
Step 7: Slice the adhesive
If the adhesive becomes hard to cut, it has most likely cooled down. [https://www.ifixit.com/Guide/iOpener+Heating/25705|new_window=true|Use your iOpener] to reheat it.
Insert a third opening pick at the bottom right corner of your phone.

Leave the opening pick in the bottom left corner to prevent the adhesive from resealing.
Step 8:
Insert a fourth opening pick underneath the bottom left corner of your phone.
Slide the opening pick up to the volume button.
Don't slide the opening pick any further! A flex cable runs next to the volume button.
Step 9:
Insert a sixth opening pick at the left edge of your phone next to the top end of the power and volume button cut out.
Slice the remaining adhesive of the left edge.
Slide the opening pick around the top left corner and along the top edge to cut the remaining adhesive.
Step 10: Remove the rear glass
Remove the rear glass.
Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
Step 11: Unscrew the midframe
Use a Phillips screwdriver to remove the seventeen screws securing the midframe:
Nine 4.4 mm-long screws in the upper area of the midframe
Eight 3.4 mm-long screws in the lower area of the midframe
Step 12: Insert an opening pick
The midframe is held in place by plastic clips.
Insert an opening pick between the midframe and front panel assembly on the bottom of the phone near the charging port.

Step 14:
Slide the opening pick along the top edge to release the plastic clips.
Step 15:
Slide the opening pick along the right edge to release the remaining plastic clips.

Step 16: Swing open the midframe
Avoid straining the side button flex cable in the following step!
Carefully swing the midframe open in the direction of the power and volume buttons and place the midframe close to the phone assembly.
Step 17: Disconnect the power and volume button flex cable
Use the flat end of a spudger to pry up and disconnect the power and volume button flex cable from the motherboard.
Step 18: Remove the midframe

Remove the graphite film.
Step 21: Peel the pull tabs off the battery
