Homebrew Question Bricked My Switch Can Someone Help?

[Taorn]

I'm using Hekate. [...]
My SD card is FAT32 with around 32 GB of space so I don't think I can do a full backup.
I guess I'll do a eMMC SYS soon.

You can still backup your whole nand. Hetake will split the backup into multiple files. You just need enough space on your sd card.

How would I restore the split pieces, if necessary?

I don't think you can, it'll dump the nand in 2GB pieces but it isn't able to restore the nand from that. You would have to use hacdiscmount to restore the user partition without an exfat card.

You can join them with a script that Hetake also generates with the split files.

There might also be a way to restore the splitted parts. If this is the case, then I don't know how.

The issue being is once you've joined the split files to restore them, they won't fit on the SDcard.

Well, if the time comes I could just buy a SD card and format it as exFAT for the purpose of salvaging the Switch. But how would I combine the split parts at all? Just cat?

Wtf Nintendo, why a game can edit this partition?

Yes, currently the way would be to format your sd card with exfat and then copy your backup file.

Some along the lines of cat nand.bin.* > nand.bin should help on Linux. On Windows you would use copy /b nand.bin.* nand.bin.
Hetake also generates scripts for that, if you use it for your dump.

Yeah, I'm pretty sure that's how to do it. There should be some scripts pre-written for you on the Hekate releases page.

Because it's not a game. It's a malicious homebrew application disguised as a game.

If anybody wants to make their rawnand.bin available together with biskeys, I don't mind taking a look. As long as the nsp didn't affect BOOT0/BOOT1 or PRODINFO/PRODINFOF should be able to build a clean nand.

Current speculation and examination has implied that PRODINFO gets rewritten.

 

[PrEtZaL]

In that case if PRODINFO is rewritten and no backup was taken it's beyond repair as this is written at factory and is console specifc . If somebody can confirm by mounting the PRODINFO partition?

WOW!! Okay, I almost just tried an .nsp Eevee game, but I just happen to come across this Thread. So is there anyway to disprove a legit or fake .nsp or .xci game file?

Eevee should be fine. Just extract the NSP (and then NCA) in hactool and see if it has what should be there.

Okay thanks

Yeah, it is incredibly easy to brick your Switch. Honestly there should be a payload where you're forced to make a backup on first boot.
I'm pretty sure there's something similar to PozzNX but in NRO form but I'm not totally sure.

yeah unfortunately even if that was done I would imagine most people would still not dump their sd card contents once its dumped and any nefarious brick maker would just overwrite the dump on the SD card too

This is why I recommend the 3-2-1 rule for anything you want to keep safe.

THREE copies on TWO different media and ONE of them offsite. A copy on your SD card, a copy on your PC and a copy stored in the cloud means if you do lose all 3, well, the universe just hates you.

After many hours of research (literally 2 seconds) I can conclude that this was SwitchFuckerUpper, a preexisting bricker, packed into an NSP.

So BIS = kill?

Can that be fixed?
