well first off, you can't just upload any traditional chinese files. You will need to download a FS for your specific phone and extract the .lng and .t9 files for traditional chinese out of them using main2raw and SEFStool4. I am going to assume that if you have a difficult time copying files from your phone to your pc your cid is to high. I need to update the tutorial one of these days to account for higher cids, but the easyest thing you can do is just create a customize_upgrade.xml file and put in it what you were going to add to the customize.xml file and upload the file to the same directory as customize.xml. then when you restart your phone, what was added into customize_upgrade.xml will be added automatically to your customize.xml
