Video Overview 

Operation Method

Step 1: Remove touch module

Tear down the touch module from the original display, use hot air gun to blow and steel tool to pry carefully.

Step 2: Clean out the touch module

Clean out the black adhesive from the module with solder flux and solder wick and heat up with hot air gun.

Step 3: Connect the touch module to the touch module connector (please refer to the video for detail operation)

For iPhone 11:

1) Find the touch module connector on the mobile phone main board as the picture shows below. Remove the resistor R8156 which is next to the touch module connector.

2) Use conductivity copper conductor to connect F11-14 pin (12C3 bus data signal), to the data signal point of the resistor R8156.

3) Find the position of the inductor L8100 (1.8V power supply) next to the touch module connector as the picture shows, and connect E16 to L8100.

4) Find the position of the capacitive clock signal and connect it to F13-12 Pin.

5) Find the ground-to-ground pin on the touch module, and connect it to the ground-to-ground position of the main board.

For iPhone 11 Pro and iPhone 11 Pro Max:

1) Find the touch module connector on the mobile phone main board as the picture shows below. Remove the resistor R8120 which is next to the touch module connector.

2) Use conductivity copper conductor to connect F11-8 pin (12C3 bus data signal), to the data signal point of the resistor R8120.

3) Find the position of the capacitor C8190 (1.8V power supply) which is next to the touch module connector as the picture shows, and connect it to E160.

4) Find the position of the capacitor C8121 (clock signal) which is next to the touch module connector, and connect it to F13-7 Pin.

Find the ground-to-ground pin on the touch module, and connect it to the ground-to-ground position of the main board.

Step 4: Find a place to fix the touch module

Find a place to fix the touch module. It is recommended to fix it between the battery and the main board as the video shows.
