On some 3DS systems(such as 3DS XL), there's a plaintext FAT16 boot record located at NAND offset 0x4000. This block does not exist for launch-day 3DS systems. This is the only plaintext block for this "partition".

This 0x200-byte sector contains New3DS key(s), this entire sector is encrypted with a console-unique keyX+keyY. The keyX+keyY for this is generated by the New3DS [[FIRM|arm9bin-loader]]. Once the arm9bin-loader finishes decrypting this data, the keyX+keyY in the keyslot are then cleared, then the memory used for generating the keydata is disabled(after it finishes using it for TWL key init).
The first 0x10-byte block is encrypted with AES-ECB, therefore the rest of the blocks are presumably encrypted with AES-ECB too.
