📋 Step-by-Step Instructions
Power Off & Prepare Workspace
Power off the iPad. Lay it face-up on a clean, padded surface. Have all tools within reach. This repair requires patience — rushing leads to broken LCDs.
Heat the Top Edge
Apply heat to the top edge of the iPad (opposite the home button) for 2-3 minutes. Keep the heat source moving to avoid hot spots. The glass should be hot to touch but not burning.
Apply Suction Cup & Create Gap
While the adhesive is warm, attach a suction cup near the top-left corner. Pull up firmly while pushing down on the frame. A small gap should appear. Insert an opening pick immediately.
Work Along the Top Edge
Slide the opening pick along the top edge, staying shallow (about 2-3mm). Leave picks in place every inch or so to prevent the adhesive from resealing. You may need to reheat as you go.
Heat and Work the Side Edges
Heat the left edge, then carefully work picks down that side. Repeat for the right edge. Take your time — this is the most tedious part.
Heat and Work the Bottom Edge
The bottom edge (near home button) has the strongest adhesive. Apply extra heat and work slowly. The home button area requires special care to avoid damaging the Touch ID cable.
Lift the Digitizer (Carefully)
Once all edges are separated, carefully lift the digitizer from the left side. It's still connected by a ribbon cable on the right side. Lift only about 30-40 degrees.
Disconnect the Battery
Before disconnecting the digitizer cable, locate and disconnect the battery connector for safety. It's under a metal bracket on the logic board.
Disconnect the Digitizer Cable
Locate the digitizer ribbon cable connector. Use a plastic spudger to flip up the ZIF connector latch, then gently slide out the cable. The old digitizer is now free.
Remove the Home Button
The home button assembly must be transferred to the new digitizer. It's held by bracket screws and adhesive. Carefully remove the bracket, then peel up the home button assembly with its cable.
Clean the Frame
Remove all old adhesive residue from the iPad frame. Use isopropyl alcohol and plastic scraping tools. A clean surface is essential for the new adhesive to bond properly.
Install Home Button on New Digitizer
Carefully transfer the home button assembly to the new digitizer. Align it precisely in the cutout and secure with the bracket and screws.
Apply New Adhesive
Apply the pre-cut adhesive strips around the frame edges. Don't remove the protective liner from the outer side yet.
Connect New Digitizer Cable
Slide the new digitizer's ribbon cable into the ZIF connector and flip the latch down to secure it. Make sure it's fully inserted.
Reconnect Battery & Test
Before sealing, reconnect the battery and power on the iPad. Test touch response across the entire screen and verify the home button works. If there are issues, fix them now.
Seal the Digitizer
Remove the adhesive liner and carefully lower the digitizer into place. Start from one edge and work across to avoid trapping air bubbles. Press firmly around all edges.
Final Testing
Power on and verify:
- ✓ Touch works across entire screen
- ✓ No dead zones or ghost touches
- ✓ Home button responds
- ✓ Touch ID works
- ✓ Display shows properly (LCD not damaged)
🔧 Troubleshooting
Lines or spots on LCD
The LCD may have been damaged during removal. Unfortunately, this requires an LCD replacement too.
Touch not working in certain areas
The digitizer cable may not be fully inserted. Open and reseat the cable connection.
Touch ID not working
The home button cable may be damaged or not properly connected. Check the connection. If the button itself was damaged, Touch ID cannot be restored.
Glass lifting at edges
Insufficient adhesive or old adhesive residue preventing proper bonding. You may need to reopen, clean thoroughly, and apply fresh adhesive.
💡 Pro Tips
- Buy extra adhesive strips — you may need multiple attempts
- A heat mat that slides under the iPad is easier than a heat gun
- If the glass is shattered, apply packing tape over it first to keep shards contained
- Watch a video walkthrough before starting — iPad screens are challenging
- Consider a screen with digitizer AND LCD pre-assembled for easier installation (more expensive but fewer steps)
