Repairing Wi-Fi issues on iPhone 12 and newer models has long been a technical hurdle due to Apple’s parts pairing restrictions. Standard tools often fail to address activation or hardware mismatches. However, JCID Luban Technologies now leverages JCID Luban Technologies’ groundbreaking tools (iPhone WiFi chip and WiFi activation module) to simplify the process, enabling technicians to unbind, activate, and restore Wi-Fi functionality efficiently.

Core Tools & Methodology
The JCID WiFi Activation Module and P15 Programmer remain critical for success. This blog's approach mirrors JCID’s proven workflow but emphasizes precision and compliance. All tools mentioned are available at www.partsfixit.com.
Step 1: Retrieve Original iPhone Wi-Fi SN
Let's prioritize identifying the original Wi-Fi serial number (SN).
Option 1: Connect the iPhone to the JCID Repair Assistant. If the activation certificate is recognized, proceed.
Two scenarios apply:
Scenario 1:  Wifi SN Detectable via JCID Repair Assistant Or Flashing Software (iShalou, etc)


Option 2: Use flashing tools like iShalou to query the SN. Success allows progression; failure requires Scenario 2.




Scenario 2: SN Undetectable
Remove the iPhone’s NAND Flash chip. Use the JCID NAND Programmer with the “Query Factory Data” function to unbind and extract the SN.


Step 2: Remove Faulty Wi-Fi Chip
Tools of Choice:
JCID Aixun 2nd Gen IC Chip Grinder: Precision-grind the damaged IC (recommended for accuracy) or Hot Air Gun + Pry Tools: Alternative for manual removal.


Step 3: Activate New Wi-Fi Module
Connect the iPhone to the P15 Programmer and a computer.
Insert the JCID Wi-Fi Chip into the Activation Module, then load both into the programmer.


Open JCID Repair Assistant and confirm device detection via connection P15 programmer. After successful connection, we see that the chip status is not activated.


Click “PCIE Wi-Fi Activation” in the software. We see that the chip status is activated.


Once the chip status switches to “Activated,” install it on the motherboard.


Step 4: Functional Testing & Final Assembly
Pre-Installation Check: Use an iPhone Motherboard Test Fixture to validate cellular, Bluetooth, and power functions.
Reassembly: After confirming normal operation, reinstall the iPhone and verify Wi-Fi connectivity. The original SN and MAC address will remain intact.
