Hacking [HELP] How do i extract partitions from a full nand backup?

[Deleted member 373223]

How do i extract partitions from a full nand backup? i already know how to get the xorpads. (i want to get twl_nand specifically, since i have an old bakup and in my current using sysnand i broke magically for no reason it broke)

Ugh... http://3dbrew.org/wiki/Flash_Filesystem#NAND_structure
Use an hex editor.
Now please refrain from doing this.

And this, too. For CTRNAND, however.

What's the difference between the CTR-NAND partition and the CTR-NAND FAT16 File System?

CTRNAND partition is encrypted with console unique keys.
The partition must have some empty space of some sort.
The partition contains the FAT16 FS.

thanks! i will try to use an hex editor! (even if i may end up bricking even more my twl_firm, i will buy a 2ds anyway so)

Why extracting? Why not just Copy the data from backup from offset 0x00000000 to 0x0B100000 and overwrite that region on the defect nand?
That region is the same across all backups for one cosole.

because it isn't my entire nand that isn't working but only the twl_nand?

Was this a question? That region is not the whole nand. Its offset is only for TWL_NAnd. You won't lose any data/settings if you only broke TWL_Nand like you said.

though i think i will replace that ONLY to my twl_nand partition to do not risk bricking other nand stuff

the twl_nand is TWLN right? (i think because: TWLNand)
