I know that without this chip, the Wi-Fi will not work. It is called the UTRIP_RF on ZXW, but I am not sure where to find a replacement besides on a Donor Board. You will need a hot air station and you will want to ideally pre-heat the board. Remove all of the underfill from around the chip. Add flux and hit it with hot air. I like to use around 360C. Here are some images of my repair. [image|1765760] [image|1765761] Good luck. Hopefully you don’t have to run new traces.
