=== CTR Transfer (3DS) ===
A '''CTR Transfer''' is a process that '''rewrites the entire CTRNAND partition'''. It is the "nuclear option" for the 3DS and is '''mostly used to fix bricks''' that cannot be repaired by other methods.
 
* '''Cleaning:''' Overwrites corrupted system files with a clean image.
* '''Rewiring:''' Uses GodMode9 to rebind the new firmware to your unique hardware keys (Fix CMAC).
* '''Rebuilding:''' Restores the Title Database so your icons reappear.
 
'''Steps:'''
1. Boot into '''GodMode9''' (Hold Start on boot).
2. Navigate to `[0:] SDCARD` -> `gm9` -> `out`.
3. Select your CTRTransfer `.bin` file.
4. Select '''CTRNAND options...''' -> '''Transfer image to CTRNAND'''.
5. Once complete, select '''Fix CMACs for drive''' to rewire the firmware.
 
|-|Wii U=
=== Firmware Rewiring (Wii U) ===
Used primarily for fixing the **160-0103** (System Memory) error.
 
* '''Rewiring:''' If your internal MLC chip is dying, you must "rewire" the boot process to an SD-card-based RedNAND.
* '''Tools:''' Requires '''ISFShax''' and the '''Minute''' menu.
* '''Rebuilding:''' You must rebuild the `sys`, `usr`, and `vol` quotas on the new SD-MLC to ensure the OS can boot.
 
|-|Wii=
=== NAND Rebuilding (Wii) ===
Used to fix "Low-Level Bricks" where the System Menu fails to load.
 
* '''Cleaning:''' Removes "dirty" or "stubbed" IOS files that prevent booting.
* '''Rewiring:''' You must inject your unique `keys.bin` into a clean</tabber>'''WII U'''

Mostly used for region changing, RedNAND, and fixing corrupted system files.

Firmware Rewiring (Rebuilding) for 3DS, Wii U, and Wii.

Manual CTR Transfer

Manual CTR Transfer is mostly used for fixing bricks. It overwrites the entire CTR NAND with a clean version of it.
