Error 2110-2118 after picofly installation

[dangbawu]

Hello,

After installing a picofly, I started getting this error of 2110-2118 on my switch with no wifi and Bluetooth connectivity.

After doing some research i noticed I must’ve knocked off the cap to the left of the cpu which I did. I took one off a donor board and replaced it. After testing with a multimeter there seems to be a connection from the trace to the cap. However still the error persists… I reflowed the wifi chip - didn’t work. Replaced and reballed the wifi chip from a donor - didn’t work. I’ve put this pcb in a known working antenna - didn’t work

Any thoughts or things that stand out from this pcb?

Thank you

The thing come to mind is the BCM4356

I replaced that IC from a donor and it still doesn’t work. I’ll try to reflow it but it seems to be installed correctly

I would check components near that chip.
