Introduction

Due to Apple's part pairing system, Wi-Fi repairs on iPhone 12 or later models were impossible for independent repair shops for years. But now, REWA Tech has found a groundbreaking solution. This is the first time we've made such a huge breakthrough in iPhone repairs since the iPhone 12 release. This guide will show you how to perform a Wi-Fi chip repair on an iPhone 13. This method can be applied to iPhone 12 and later models, however.

iPhone WiFi Chip Repair Solution

Tools

Step 1

Cover the cameras with protection stickers.
Remove the motherboard and split it.

Step 2

Test the circuits related to the Wi-Fi module to verify that they are normal.

Step 3

It is not possible to read the Wi-Fi serial number (SN) simply by connecting the iPhone to the programming software. Therefore, we will remove the NAND chip.
Heat the NAND chip evenly with a hot air gun at 420°C and airflow 80.
Pry the NAND chip up.
Apply some flux to the soldering pad of the NAND chip.
Remove the tins from the soldering pad using braid and a soldering iron.

Step 4

Place the NAND chip in a Luban programmer.
Connect the programmer to a PC and open the programming software.
Click "Check Factory Data" to read the EcID of the iPhone.
Read the EcID from the NAND chip.

Step 5

Place a new Wi-Fi module into the Luban programmer to write in the Wi-Fi SN.
Copy the EcID and select WiFi Operations on the navigation menu.
Paste the EcID and click "Check now."
Then click "Write now."
The Wi-Fi SN has been written into the new Wi-Fi module.

Step 6

Place the signal board onto a fixture.
Cover some other components with Kapton tape for protection.
Heat the Wi-Fi module with a hot air gun and use a pry knife to remove the edge adhesives.
Pry up the Wi-Fi module.
Apply some flux to the soldering pad of the Wi-Fi module.

Step 7

Remove the tins from the soldering joints of the signal board.
Remove the tins from the soldering joints of the logic board.
Align the new Wi-Fi module carrying the SN to the soldering pad.
Solder the new Wi-Fi module with a hot air gun at 380°C and airflow 60.

Step 8

Solder the NAND chip with a hot air gun at 380°C and airflow 60.

Step 9

Put the logic board and the signal board into a motherboard-layered test fixture.
Connect the iPhone 13 screen cable and the power cable.
Use a pair of tweezers to trigger the power-on.
The iPhone 13 should power on properly.
Go to settings to check if the Wi-Fi function toggle is resumed.
