From [[3.0.0-5|3.0.0-X]] this was fixed by setting the bit in Kernel9 after poking some registers in that region. On New3DS arm9loader sets this bit instead of Kernel9. | From [[3.0.0-5|3.0.0-X]] this was fixed by setting the bit in Kernel9 after poking some registers in that region.

This flaw resurged when it gained a new practical use | This flaw resurged when it gained a new practical use: retrieving the OTP data for a New3DS console in order to decrypt the key data used in arm9loader. This was performed by downgrading to a vulnerable system version. By accounting for differences in CTR-NAND crypto (see partition encryption types [[Flash_Filesystem#NAND_structure|here]]), it is possible to boot a New3DS using Old3DS firmware 1.0-2.x, and retrieve the required OTP data using this flaw. | ||
