* if it asks for "titlekey", try (not sure if correct) : 1B10029010493486682DBC539DFCAE42
* i tried multiple options but get a lot of errors...
also try open the fragment file with a hex editor,
on the first line it may give more info about the type of file this is : nvd0
tried google, looks like some archive (like zip) maybe
but no idea how to extract it...
@tokke001 that's correct title key. You can find it also with HxD. I will try tomorrow to extract it, actually in the morning, I think it's possible, because of the title key, every title update before had the same title key, I had success, so, I'm optimistic
