iPhone 7 WiFi grayed out
Hi guys, I have an iPhone 7 here, WiFi grayed out. Upon testing, I confirm the WiFi chip has problem and needs to be reballed. What I am not sure is the NAND chip. I know WiFi IC is bound to the NAND, so if the WiFi chip is to be replaced with a new one, then NAND must be removed and reprogrammed to unbind the the Mac address. However, I am not going to replace the WiFi chip with a new one, I just want to reball it. In such case, do I still need to remove the NAND chip and reprogram it? I checked on youtube, some repairers just reballed the WiFi chip and didn’t touch the NAND, however, some reballed both of them even they didn’t change the WiFi chip. So I am a bit confused. Do I need to remove/reprogram the NAND even I don’t replace the WiFi chip?
Это хороший вопрос?

The WiFi chip is on top of the reverse side of the logic board. But don’t attempt to repair it, this is not a simple DIY job. Can only be done by an experienced professional. If you are not a professional, attempting to repair it will only ruin the phone. @fegelein3290
