You can only recover by restoring a full raw nand backup, if you have one. If not, then that's probably it. Creating a fresh boot0/boot1 and NAND fw with ChoiDujour does not work.
I suggest everyone who was affected starts looking for a new unpatched unit asap, and learn from that mistake and create a full NAND backup right away before never ever again running anything that wasn't posted by the original creators or compiled from Github yourself.
Something like that has never happened to me before, and I am usually very cautious.
I think it's not the right course now to blame everyone for being cheap and trying to get a free SX OS instead of spending a few bucks. I have a SX Pro already, I was just curious to see if it's actually real, and the result is a bricked Switch. It was stupid, and I surely learned my lesson. I already ordered a new Switch.
But to make that perfectly clear: The thing everyone should be worried about is not that some stupid users fell for it, but that there is a payload that completely fucks your Switch and basically anything you download that was not posted by the creator or acquired from the Github releases page can be just a renamed brick payload. This thing is floating around and there will be more people posting it all over the usual pages just for shits and giggles.
Be glad that it was removed so quickly from gbatemp, 10 minutes more and we would have had another 100 bricked users.
