OTPHelper is small tool for the 3DS console, for helping with the downgrade and OTP dumping process.

Note: This tool is deprecated. The way to go for A9LH installations now is CTRNAND transfer (O3DS) or OTPless install (N3DS). Always refer to Plailect's guide.

Features

  • Actual dumping of the OTP.bin (0x100 or 0x108, only on FW < 3.0) included for convenience. Not shown in the screenshots, this is in the ARM9.bin.
  • Generate OTP0x108.bin from OTP.bin (on FW 9.0+), if you forgot getting that file the first time around.
  • Unbricking the FW 2.1 EmuNAND (N3DS only). This does, in one step, what would otherwise require: two NAND XORpads, the emuNAND_bricked.bin backup on your PC, 3DSFAT16Tool, hex-editing the header of the emuNAND_bricked.bin and writing back the fixed emuNAND_bricked.bin backup via Decrypt9WIP. So, much faster.
  • Includes EmuNAND/SysNAND Backup & Restore, CTRNAND Dump & Inject, FIRM Dump & Inject and Padgen features from Decrypt9WIP for convenience.
  • Multiple safety clamps in place to make this as safe as possible.
  • Various options to restore your SysNAND to working order in case something goes wrong.
