Before activating and repairing the iPhone Wi-Fi function, we need to check the original iPhone WIFI SN. According to Phonefix's understanding, there may be two situations here, one is that the iPhone WiFi SN can be recognized by the platform system or flashing software, which helps the iPhone WIFI function repair process. In another case, the platform system or flashing software can't query the iPhone WiFi SN, in this case, we need to remove the iPhone Nand Flash chip, and then use the iPhone Nand programmer to unbind and obtain the iPhone WIFI SN.

Case 1: Use JCID Repair Assistant Or Flashing Software (iShalou, etc) to get the iPhone WIFI SN.

Option 1: Connect the iPhone to the JCID Repair Assistant to see if you can get the activation certificate. If it works, go to the next step. If it doesn't, go to Case 2.



Option 2: Connect the iPhone to the computer, and then use Flashing software like iShalou. Enter the shalou to query the WiFi SN, click to Query, if the iPhone WIFI SN query successfully, then go to the next step. If it doesn't, go to Case 2.



Case 2: Use Nand Programmer to unbind and get the iPhone WIFI SN.

Disassemble the iPhone hard disk, put it on the iPhone Programmer, open the corresponding Repair Assistant, use the "Query Factory Data" function to query the key data of unbinding WIFI, and get the iPhone WIFI SN.



After getting the original iPhone WIFI SN, we can remove the iPhone WIFI module. Phonefix recommends using a JCID EM02 CNC Grinder to grind off the WIFI IC, or using a hot air gun and pry tool to remove the WIFI chip.

Connect iPhone to P15/V1S Pro and computer, Put the JCID WIFI module into P15/V1S Pro programmer and then put the JCID WIFI chip into the WIFI activation module.



Open JCID Repair Assistant on the computer and connect P15/V1S Pro. After successful connection, we see that the chip status is not activated.



Click PCIE WIFI Activation to activate the WIFI chip. At this time, the chip status is activated. Install the JCID WIFI chip to the iPhone motherboard.



Phonefix team recommends testing the iPhone motherboard function with an iPhone motherboard test fixture before installation. All tests are normal. Then install the iPhone and check the wifi function. Now the WIFI function has been repaired, the iPhone SN is still the same, and the WIFI address is also displayed.
