Today I have bricked my Cowon J3 player after a failed firmware upgrade. And I've been able to unbrick it using tcctool. So first of all thank you for creating such a useful tool!

In order to make it work with Cowon J3 I've applied the attached patch. So I've thought it would be nice to include it into the tool so that other Cowon J3 users can benefit from it too.

The credits for getting the right values for this player should go to this user:

Hm, not sure who to credit for this patch ("joecool"?). I don't know if we accept essentially anonymous patches.

Well, I took the hex value from that forum post. I don't know if he's the original person who got the value though. Given that it's a value "fixed" for this device, I'm not sure if any person can hold the copyright of that. I'd say that no. This is why I see it OK to add this patch, even if we didn't know who's the original person that extracted the hex value.

Just my 2 cents.

In case this is a problem, I happened to see the magic sdcfg value for the j3 somewhere (it might even have been in a patch on flyspray!), and I did a cleanroom reimplementation of it (see attachment)

My version even has the advantage of being sorted correctly :)

hehe, good! Is the "0xb011" instead of "0xb057" correct?

Ah, good catch, sorry. Fixed version (still by hand, no copy/paste here! :)
