Since Decrypt9WIP (Aug 2016 or later) 's CTRNAND transfer enhanced the region changing, we don't need the old tutorial's Part 1 ~ Part 11 now.
From
Plailect's Guide (CTRNAND transfer based):
Preparations
- TWN/CHN 3DS 4.1-9.2
- DS Flashcart (for 4.1-4.5, optional)
- Decrypt9WIP
- 2.1.0-4 JPN/USA/EUR CTRTransfer image
- SafeA9LHInstaller
- AuroraWright's A9LH fork
- data_input_v2
- Luma3DS
New Part 1 - Boot Decrypt9WIP
For 4.1-9.2 with browser:
N1-1-1) Put Launcher.dat from Decypt9WIP to SD root
N1-1-2) Use Internet Browser to visit
http://go.gateway-3ds.com/ (or
http://soar.im/go/) to boot Decrypt9WIP
For 4.1-4.5:
N1-2-1) Put Decrypt9WIP.dat to SD root
N1-2-2) Use DS Flashcart to install Decrypt9WIP.NDS
N1-2-3) Boot Decrypt9WIP by MSET
New Part 2 - Use Auto CTRNAND transfer to do all the following things
- Backup TWN/CHN SysNAND
- Change region to your selected one: JPN/USA/EUR
- Downgrade SysNAND to 2.1.0-4J/U/E
See
Plailect's Guide.
New Part 3 - Install A9LH
See
Plailect's Guide.
New Part 4 - Restore TWN/CHN SysNAND (or TWN/CHN EmuNAND) to A9LH SysNAND
N4-1) Rename Decrypt9WIP.bin into X_Decrypt9WIP.bin
N4-2) Put X_Decrypt9WIP.bin into SD:/luma/payloads/
N4-3) Put TWN/CHN EmuNAND backup to SD:/files9/
N4-4) Hold X on power-on to boot Decrypt9WIP
N4-5) Go to SysNAND Options -> SysNAND Backup/Restore... -> NAND Restore (keep a9lh) to inject TWN/CHN EmuNAND to A9LH SysNAND
N4-6) All done!
* If you want to change H&S into any software on TWN/CHN A9LH SysNAND, delete 0004001000026300 (TWN) 0004001000028300 (CHN). Otherwise Decrypt9WIP cannot dump hs.app properly!
