Hacking Exfat update offline gone wrong

[GeraltOfRivia]

Hello everyone. I tried to help my friend into fixing a blue screen switch after exfat update gone bad. Unfortunately after many attempts to revert back the (original?) file "BCPKG2-1-normal-main" to its place, with memloader and hackdiskmount, we failed. I don't know either if that was the right file to move or the one merged with the (wrong) exfat update. Obviously he didn't back up his nand... Now I wanted to know if it's possible to fix it, maybe restoring another nand from a switch.. if we have the same fmw is possible to "swap" the nand from another console? I know that prodinfo is console unique but, is there a way to get the prodinfo from his console and fix it restoring nand from a working switch? Sorry if i'm saying a lot of bullshit but I really don't know how to proceed

You can get prodinfo via memloader and use it to recerate the NAND. How is a mystery to me tho.

Fingers crossed, just make sure you do a backup first.
