There are 2 versions of the firmware: the European(EU) firmware and the Korean(KR) firmare. There are some differences in the two versions, but both the versions a composed by 2 files: T10.RSC and T10.ROM. T10.RSC is the same for the EU and the KR version. The T10 doesn't allows changing from the EU to the KR firmware and vice versa, but it can be forced to do that and probably to change the original firmware with a custom one by using the FWDN or the TCCTOOL wich is easier to use.
