Hacking Bug in Waninkoko's Firmware Downgrader 1.0

[piratesmack]

I think I have found a bug in Waninkoko's Firmware Downgrader 1.0

Well I used it to update a 3.2U Wii to 4.0U.
And after 4.0U finished installing, it asked me something like "Change console area? Not doing this will result in a semi-brick"

I thought it was weird that it asked me that, since the Wii was already set to US. So I pressed B to skip

And good thing I did, because I took a look at the source code and found this in menu.c:

{ "4.0U", FW_REGION_JAP, 0x100000002ULL, 417, 0x10000003cULL, 6174, 0x100000101ULL, 9, 0x100000100ULL, 5 },

If I would have pressed A:

case FW_REGION_JAP: {
ÂÂÂÂÂÂÂÂareaÂÂÂÂ= CONF_AREA_JPN;
ÂÂÂÂÂÂÂÂgameÂÂÂÂ= CONF_REGION_JP;
ÂÂÂÂÂÂÂÂvideoÂÂ = CONF_VIDEO_NTSC;
ÂÂÂÂÂÂÂÂregname = "JAP";

ÂÂÂÂÂÂÂÂbreak;

Wouldn't that have semi-bricked my Wii?

Another thing I noticed, it didn't download and install IOS60 (but that might just be because I already had it installed)

UPDATE

Firmware Downgrader v1.1 released:
http://files.filefront.com/firmware+downgr...;/fileinfo.html

It looks like Waninkoko has fixed the bug in the firmware list and added return to Homebrew Channel support

Thanks, Wanin

Another strange part I don't understand. SysMenu3.4 officially runs on IOS50v4889, but the table loads IOS30v2816. Is it means I have to make sure I already have IOS50 inside if I upgrade from 3.2 to 3.4? And what's the purpoe to install IOS30v2816?

That is strange.
Maybe Wanin made another mistake?

As I said in the original post, I noticed that the downgrader didn't install IOS60 when updating to 4.0U.
It only installed System Menu v417, BC v5, and MIOS v9. (Good thing I installed IOS60 before.)

3.4 runs on IOS50? Mmmm. then I made some mistake when checking that.

Firmware Downgrader won't install IOS60 if it's already installed.

Thanks!

Also notice the source code loads IOS30v1039 for SM3.2, but it seems official 3.2 comes with IOS30v1040.

According to noobwarrior7, IOS30 v1039 is preferred over v1040
