If you want to set default language after flashing all you need is to modify private\10202be9\1020503B.txt:
0x1 int XX 16777216 cap_rd=ReadDeviceData cap_wr=WriteDeviceData
where XX is language code
modify in rofs2 and you are good to go
After reflash with CFW you will see the setup language. Put 20 and after CFW flash the language will be English, but Australian
