I, have the exact same problem, and pass throw the exact same test, Android won't detect any wifi device, after a wifi ic reflow, Android detects wifi and Nintendo switch boot normally!! Also as an extra I add a thermal pad from a dead PS3 to the wifi ic, for extra heat dissipation and pressure
i found a way to get the Switch Back Running by letting the Battery dry and waiting for 1-2 days. Sometimes after that i can use her again but the error comes back after a restart or eventully in the Sleepmode."
I have the same problem. I only have to wait about 24 hours, then it will load past the Switch logo and I can play games. I don’t have to let the battery die. I assume the switch must stop trying to use WiFi after something close to the 24-hour mark, but I would get the error and it would freeze up again if I put it to sleep or rebooted it. I finally just put mine in airplane mode and now I don’t have a problem at all (other than I can’t use WiFi). I still get error messages when I boot it up telling me there is a problem (mostly saying the WiFi is off), but I can just skip past them and play a game like normal.
