hm sadly not... i tried to bring my broken switch to an console repair shop, but they weren't able to fix it either.Hello! Any news about flashing new BCM IC? I have switch with new BCM without working bluetooth

here is what I measured from donor board. My DMM can't measure inductor,so the left one no idea.

OH WELL. then maybe my donor board had that piece removed or used. I will check back again when I have another Switch comes in.Thank you SO MUCH for the speedy reply and measurements!!

I actually have a "before" picture (this attachment) that I took and the part that you labelled "empty" actually have a chip on it... just FYI.
DId you managed to do it ? Did it work ?Hello guys,
i have some time so i try go back to this issue. After some research i found something to work with.
it is possible to dump the OTP.

On Page17 the procces of programming the chip using android.
You need the Manufacture Firmware.
I got this find here: https://github.com/MoKee/android_vendor_lge_d851/blob/mkl/proprietary/etc/firmware/fw_bcmdhd_mfg.bin
this allows you to dump the OTP from a working WiFI chip. "wl cisdump"
with the command "> wl ciswrite OTP.bin" you can write to it.
I downloaded already the AndroidOS for the Switch. And try this today, wish me luck
a reflow of the wifi ic may help
Had the idea to disable the wifi chip firmware wise a long time ago but i couldn't find anything to do this at that time.It may, but does the L4T log indicate that there is definately a problem with the wifi chip? I still can't get it to boot L4T Ubuntu fully on a patched v1, it gets stuck before initializing the display and putting up the user experience screen.
I was also wondering if flushing under the chip with a syringe of alchohol might help, if a loose bit of solder is causing a short.
Edit: Is there a way to disable wifi chip in cfw to get a normal boot?
Don't bother with reflows. I worked on an oled switch that shows 2110-1118 error code every time I try to search for wifi networks. Tried to reflow the wifi chip, worked for 2 days and the error code came back. Ordered several replacement chips from aliexpress and replaced it, everything's back to normal.a reflow of the wifi ic may help

There must be some hardware check at boot time because my current switch had a broken card reader which also refused to boot. (stuck at switch logo) Swapping it out with another one fixed it.
Would be great if we find a way to disable this checks.

You can find those replacement chips on aliexpress for $2-5. Try to buy 2-3 chips at once, sometimes these recycled chips may not work. Also get a stencil because you need to reball it yourself.
You can take it to your local repair shop and let them do it. Shouldn't be very expensive if you bring the replacement chip with you, a 10 minute job at most I'd say.I haven't had any experience with reballing, though it is good to know that replacement chips are available

If you had problems with wifi in ofw before it refuses to boot, then I'm 90% sure is the wifi chip's issue. You can also flash android and see if you can get wifi/bt working.
I think I've seen people booting android/linux with a dead wifi chip, and even without the wifi chip.I didn't have problems before it stopped booting, I was going to update firmware 15.0.0 to 15.0.1 but failed to boot into maintenance mode. I had tried recovering/rebuilding firmware though, before learing about the wifi chip being a possibility.
I couldn't get any linux to boot, and I had tried Lakka and L4T 3.2/3.3/3.4 plus tried disabling the wifi driver - (it doesn't seem to save any logs to be able to diagnose boot issue), but I suppose I could try android too~I'm not nearly as familiar with android, so how can I test wifi chip in android, besides just trying to connect?
Update: Booted Android recovery fine, and installed, but first boot into Switchroot Androd got stuck.

Looking at the screenshot you posted I think it's indeed the wifi chip that is causing problems, as brcmfmac is broadcom's wifi driver:

Not sure if there's any way to "disable" the chip, other than taking it off the motherboard with a heat gun.

had only one orange screen till now and a reflow did the job. but ofcourse it depends on if its just a cracked ball or not. so you cna buy preprogrammed chips? i gues those are extracted from broken maonboards?
