Region Changing

This is add-on section for region changing your arm9loaderhax CFW SysNAND. This is done by installing the CIAs for and injecting the SecureInfo_A file from the region you want to switch to. This assumes that you already have a way to in CFW SysNAND; if you do not you should follow this first.

You MUST have already completed Part 5 and installed arm9loaderhax or you will BRICK.

You SHOULD have confirmed functional NAND backups of your arm9loaderhax 3DS (such as sysNAND-A9LHAX.bin) in case something goes wrong.

Region changing does not support the eShop through this method, and it will be updated when I am aware of one that does.

Note that region changing is experimental and can break several things.

Region changing is almost completely unnecessary since Luma3DS now supports Region Free game installs.

What you need

• SecureInfo_A.zip (mirror)
• The latest release of sysUpdater
• The latest release of downgrade_check
• The 9.2.0 firmware pack zip file for your device and the region you want to switch to:
  Note that the New 3DS 9.2.0 packs are not the same as the ones in Part 2

• New 3DS 9.2.0 (Region Change) - EUR (Mirror)
• New 3DS 9.2.0 (Region Change) - JAP (Mirror)
• New 3DS 9.2.0 (Region Change) - USA (Mirror)
  ~
