Step 2: Accessing the Motherboard
Once the back is off, you will encounter a large number of screws securing the internal frame. Remove all screws carefully and keep them organized. Disconnect the battery flex cable immediately to prevent any short circuits during the repair.
Step 3: Removing the Broken Screen
After stripping down the internal components, heat the front display. Since the screen is already broken, proceed with caution to avoid glass splinters. Use a suction cup and a plastic pick to separate the LCD from the frame.
⚠️ Pro Technician Warning:
The Redmi 12 has several hidden ribbon cables near the battery and charging port. Always use plastic tools when prying connectors to avoid damaging the delicate traces on the motherboard.
