{{Obsolete}} 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 [https://github.com/Plailect/Guide/wiki 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. ==Screenshots== https://dlhb.gamebrew.org/3dshomebrews/otphelper2.png https://dlhb.gamebrew.org/3dshomebrews/otphelper3.png ==Changelog== '''0.90''' * Removed SysNAND partition dumping/injecting. * Removed unneeded/duplicate 2.1 Unbricker Feature. [https://github.com/d0k3/OTPHelper/releases Release notes.] ==Credits== Thank these fearless people: * Damian666 and Apache Thunder for testing and verifying EmuNAND unbricking. * dark_samus3, Skaterdie, piratesephiroth and Swiftloke for testing and verifying OTP.bin dumping. * liomajor and tivu100 for helping ironing out some quirks. * al3x_10m (O3DS) for testing the One Click Setup feature. * al3x_10m, Supster131 and Wolfvak for tons of help testing the downgrade checker. ==External links== * GitHub - https://github.com/d0k3/OTPHelper * GBAtemp - https://gbatemp.net/threads/release-otphelper-otp-dumping-downgrade-helper.416996
