Hey man, go to Yongsan market. There is a new shopping mall with computer parts where you will end up when you exit the subway. That one has nothing, but the older one closer to the movie theater and parking house definitely has people you should talk to for this kind of things. I don't remember if that building has two or three floors, but it's probably on the second floor out of three floors they do these things. Shop around. They can definitely fix it. They were probably out of stock of 1.6 version chips. For 120GB, you don't even need an LBA48 patched bios to make it run so I don't think it'll be difficult.
