Installing 8707 OS onto a 8700

Is it possible to install the japanese OS onto a 8700? We are a Japanese owned company in Canada and some of our brass would like thier bbs to be Japanese.

I downloaded and installed the japanese OS file
8707hCJK_PBr4.2.2_rel302_PL3.4.0.24_A4.2.2.122.zip

I then deleted the vendor.xml file but still could not install the japanese os

Any help would be appreciated

you cannot install across hardware. only the 8700 OS works on the 8700. The 8707 is a different device.

Well what about a mod or software that will change the default language to Japanese? Has anyone ever come across something like that?
