3DS NAND SecureInfo Tool

Template:Infobox-3DS-Homebrews

Here's simple program I made for easy 'SecureInfo_A' extraction/injection I want to share. With it you don't need to worry about cutting/XORing whole FAT16 partition every time, just select untouched encrypted 'NAND.BIN' along with corresponding 'nand.fat16.xorpad' and in few seconds job is done.

SecureInfo used for system region changing (JP/US/EU etc). Basically, you install few system CIA files for your target region (3DNUS/UpdateCDN), extract and inject new SecureInfo_A to emuNAND from target region donor, write emuNAND back and 'Format System Memory' in System Settings.

Region Changing Steps:

Downgrade to 4.x FW and prepare 4.x emuNAND with DevMenu/BigBlueMenu
Download and install following system CIAs using 3DNUS for desired region:

Nothing here yet, may add later.

3Extract your emuNAND from SD card, inject into emuNAND target region 'SecureInfo_A' from donor system, insert emuNAND back to SD
Load emuNAND and perform 'Format System Memory/本体の初期化' in System Settings
