same screen that led to the sd info you posted, has a button for emmc info. IF there are no payload files on your card, I have no idea why you posted that shot as if it were a problem. If your console doesn't boot normally, without using rcm or a mod chip, then I also can't fathom how you don't understand that you have a hardware issue. You need to reflow your emmc. did you EVER create an emummc with this console or backup your emmc in any way?
If not, then the reflow is your 1 and only option to get your Switch working. Do yourself a favor and look at teardown videos or mod chip installation videos for a V1 Switch, so you have a clue where the emmc is. Then (as I already suggested) try putting pressure on the emmc while trying to power on, just to see if it will power on all the way.
