On New 3DS, the above is instead done by the [[FIRM#New_3DS_FIRM|Kernel9 loader]]. In addition to using the OTP data for initializing the TWL console-unique keys, the Kernel9 loader will generate the decryption key for NATIVE_FIRM. The final keyslot for NATIVE_FIRM is preserved, so that at a non-reset FIRM launch, the keyslot can be reused, since the OTP would then be inaccessible. | On New 3DS, the above is instead done by the [[FIRM#New_3DS_FIRM|Kernel9 loader]].
