After the thunderous success of Dark_AleX, Mathieulh, and Harleyg's TA-082 downgrader (which is pretty much the Holy Grail of the homebrew community at the moment), DAX has now decided to release the source code for the said downgrader under the General Public License or GPL. According to DAX,

I don't want to keep the ta-082 downgrade as a secret, i think this information has to be public, for future use in higher firmwares.


As it is released under the gpl, any modification to the code will have to include the source code.

So there you have it folks, here's the code. Use it well.

I've been looking over the source code of this (using harleyg's idStorage doc (http://harleyg.net/docs/idstorage.txt) as my reference), and it seems that several (seemingly) strange things are done within:
first it appears that the entire 0x045 key is replaced with a 0x09 followed by 0's, while in hg's doc it seems to mention changing the first byte of 0x045, not overwriting the entire thing with this byte changed.
Next, it appears to overwrite the entire 0x047 key with zero's instead of replacing it with the 0x045 key.

Can anyone tell me what I'm missing here?
