From what I can see your soldering looks fine, the QSB might make difference as Ubergeek stated that they do improve glitching, I always use them. I read my nand one time without QSB all three match, then I put the QSB in and read my nand three times and they all matched but when I compared one from wire dump and one from the QSB dump, they didn't match. I used QSB dump to build my image and was fine.
