I've searched everywhere for this problem and haven't found any answers yet

This might sound silly, but if you haven't figured this out yet, have you tried removing the USB port and boot without it? Don't just remove it, but also wick off the solder to clean all pads. Takes seconds to re-tin them if nothing changes and you want to put it back on.

But while it's off... I'd also look carefully for shorts, splatter, etc. If it still does not boot with it off, you might also go fishing for a shorted cap (in diode mode, only 1 end should beep on ground...)

Thanks for the suggestions! I did try removing and booting the switch without the USB C port, but unfortunately the same result. Have checked the board for shorts, didn't find any....... But I will recheck the board again.

I think is something about the capacity design of the battery

I read somewhere that the Fuel Gauge needs to be reset for the capacity design to calibrate, so I don't think it's that. Have tried three different battery's and still the same result.

Hi, do you have news?

Sorry! Nothing new to report..... Did change the emmc, but still the same problem. Strange! But I will take another look at it when I have more time. If I get some result I post it here!

Thinking about it, I also changed the usbc port and this happened, so I took it to be repaired
