Switch stuck at boot, but charges fine.Hello everyone, Essentially my switch is stuck at boot on the switch logo. This happened after it froze on a blank screen...
回答“Switch stuck at boot, but charges fine.”I actually have an update on this, and I’m fairly convinced the wifi chip (BCM4356XKUBG) is at fault. I realized that I couldn’t detect any wifi networks or that straight up no wifi-capable device was recognized in Ubuntu/Lakka/LineageOS. Other users confirmed that the wifi chip could be responsible for preventing the Switch from booting. I think that maybe the solder connections are actually the problem, and not necessarily the chip itself, as many users have reported the problem to be intermittent. So a reflow, reball, or worst-case a replacement, of the chip should fix the issue. I haven’t actually attempted a fix myself, as after leaving it on the shelf for 2 months or so it now magically started working again! And indeed Linux is now able to detect wifi networks. I’m guessing the SwitchOS attempts to communicate with the chip during bootup, and if that fails gets stuck somehow, while Linux doesn’t do this. PS: For anyone interested, i actually found a stencil to reball this chip (Wylie WL-50,...
回答“Strange Issue With Nintendo switch not charging not and power on”I’m not an expert but from what I’ve learned this info might help: If it’s not charging then it could be one the charging ICs is broken (the blue one in your image and the one above and to the left of it). The chips are called M92T36 (blue) and BQ24193 (top left). You could test for shorts on the capacitors around them, if there are any then the chip is likely broken. Especially if your switch turns back on with a working charged battery then it is likely that replacing the broken chip will fix the issue.
