This program is a 1:1 Wii NAND Dumper based on YaWnD 0.3 with several improvements. All currently | |||
available Wii NAND Dumpers misunderstand the IOS_Read() returned error code -12 and cause dumped | |||
image file to be different from extracted image of external hardware programmer for de-soldered | |||
NAND chip. | |||
== | After analyzing, the -12 code seems very likely to be ECC error but not simply to be bad block. | ||
== | And most pages with -12 return code might be unmanaged free block (ECC error due to erased | ||
< | but not programmed yet). Zeroing these pages is a bit dangerous. If it happens it's the very | ||
first time the ECC error occurred for a good page while dumping, zeros it might cause the dumped | |||
image useless. | |||
Besides the -12 code, some people encounters -11 code and stop their dumping. I guess the -11 | |||
code might be NAND read timeout and NAND status error. Stopping dumping is not a good idea but | |||
zeroing it would be safe. I also provide extra Page Debug Dump for these -11 code for user | |||
to analyze it. | |||
For whose NAND dump without -11 code, the RealWnD can help them make 100% 1:1 dump which is exact | |||
the same with hardware programmer dump. | |||
== Improvement == | |||
* Real 1:1 dump of NAND Flash by processing error code -11 and -12 | |||
* Greatly reduce dump time by opening files once instead of appending repeatedly | |||
* Add log file for all error pages | |||
* Change to new style FAT management code for easily compiling | |||
* Add Debug Dump for -11 code or others for future analysis | |||
== How To Use == | |||
Most operations are the same as YaWnd. You can use button 1 to toggle SD and USB, button 2 to | |||
toggle +ECC and normal dump, and button A to start dump. In addition, you can use button B to | |||
toggle on/off for Debug Dump. A log file WiiFlash.log will log all page error return code. | |||
If DebugDump turs on, several image files WFD_<page#>_<error code>.img will be created for | |||
future analysis. | |||

This program is a 1:1 Wii NAND Dumper based on YaWnD 0.3 with several improvements. All currently available Wii NAND Dumpers misunderstand the IOS_Read() returned error code -12 and cause dumped image file to be different from extracted image of external hardware programmer for de-soldered NAND chip.
After analyzing, the -12 code seems very likely to be ECC error but not simply to be bad block. And most pages with -12 return code might be unmanaged free block (ECC error due to erased but not programmed yet). Zeroing these pages is a bit dangerous. If it happens it's the very first time the ECC error occurred for a good page while dumping, zeros it might cause the dumped image useless.
Besides the -12 code, some people encounters -11 code and stop their dumping. I guess the -11 code might be NAND read timeout and NAND status error. Stopping dumping is not a good idea but zeroing it would be safe. I also provide extra Page Debug Dump for these -11 code for user to analyze it.
For whose NAND dump without -11 code, the RealWnD can help them make 100% 1:1 dump which is exact the same with hardware programmer dump.

- Real 1:1 dump of NAND Flash by processing error code -11 and -12
- Greatly reduce dump time by opening files once instead of appending repeatedly
- Add log file for all error pages
