Hacking Broken sysnand/emunand?

[joyoshi]

I recently downgraded an o3ds. So everything went well. Until however, when trying to make a sysnand backup, it said it couldn't be made. I just went without a backup. Everything seemed alright, until I tried booting the emunand. It just freezes on a black screen. Tried with multiple cfws, still nothing. Any way to fix this?

Run Downgradechecker and see if there are any titles, that shouldn't be there.

Extra Titles aren't bad, but if there is some unexpected version of a title, run the downgrade again.
Edit: Also this helped me 2 days ago: https://gbatemp.net/threads/guide-r...mware-w-o-upgrading-to-10-3-or-higher.413368/

Uh, well but it seems weird that the sysNAND backup fails, there must be something wrong with your system o:
Or it is your SDCard maybe, have you tried another SDCard?
Also if you can't make a NAND backup, how could you clone the NAND to an emuNAND?
Isn't that sort of doing a NAND backup?

I'm sorry that i can't help you much, but i would suggest running the downgrade again, maybe there is something wrong.

Someone with more experience should help you, because i never had a NAND backup fail, even though i downgraded 5 3DS (2 Old and 3 New).

I hope you receive help soon!

Nope, rerunning the downgrade didn't help. NAND backup still doesn't work.

All these extra titles are nothing of importance. There should be nothing wrong with the downgrade.

0x00040001000f8200 -> ????? -> cant find anything but its probably nothing system-related

Are you using the latest version of every program?
I don't know if it could help, but try Emunand9/Decrypt9 (which ever you didn't try to make a backup)

There is nothing else that could be wrong that i can think of right now...

Extracting the emunand with a tool gives a file that is 954mb.

 

[Flyingsky]

That is the right size:

+ Samsung NAND:
1.000.341.504 bytes = 954 MB

Turned out to be a faulty SD! Sorry for the trouble!

Glad you got this resolved. I was worried when you said you went without a backup D:
