Damn it! Nope, it does not work. I'll be courageous here: do you think I could install it on a 1GB card and then copy the contents to this 16GB card that was already partitioned by Nitdroid installer? I don't, but it's the only way out I see for this.
If only the installer could recognize that the file is already extracted from bz2 type... I'd like to face another problem, I'm sick of this "...FAILURE. Bailing out" while extracting.

I quit for now. Tomorrow I'll give it another try and see what happens.
