Hardware Random thought about a possible fuses fix on the switch. I might be wrong.

To start off, from my understanding if you try to downgrade the FW of the switch you'll blow some fuses up.
I was thinking, (I don't know where those fuses are located on the switch) I fixed my Wii DVD drive by bypassing the blown fuses by soldering a blob of solder on top of those.
Can't this be a solution for the fuses on the switch main board?

Like I mentioned, I don't know where they're located

I'm not to sure about how big the fuses in the wii are but I believe that the ones on the nintendo switch are small enough that you need a microscope to see them

The efuses are located on the SoC/Tegra.

Here's more information on efuses:

Most likely no since efuse isn't the same as a fuses that the Wii have or alot of electronics.
If you downgrade, I don't think it blows more fuses, rather the fuses that are already blown doesn't match the firmware it's downgrade to. Too many are blown basically.
