This allows an hardware-based NAND-attack where you can boot into an older exploited firmware, fill all memory with NOP sleds/jump-instructions, and then reboot into executing garbage. By automating this process eventually you'll find some garbage that jumps to your code.

This should give you very early ARM9 code execution (pre-ARM9 kernel). For example, you can dump RSA keyslots with this and calculate the 6.x [[Savegames#6.0.0-11_Savegame_keyY|save]], and 7.x [[NCCH]] keys. This cannot be used to recover keys initialized by arm9loader itself. This is due to it wiping the area used for its stack during NAND sector decryption and keyslot init. Due to FIRMs on both Old and New 3DS using the same RSA data, this can be exploited on Old3DS as well.
