Add Chinese Language Support Display Only!

Hey guys! I´m kinda having some problems to add chinese support display in my w850...
I just want the chinese display... don´t need to have the write support... i already flashed a lot of times with different main and fs but nothing...
my w850 now is like this now:
Platform: DB2020
OTP CID: 49
EROM CID: 52
EROM Color: Red
Region: C_ASIA
Firmware Version: R1KG001

So please.. i would really like to have the chinese support display...

Thanks!

make backup of gdfs for a start....
first off traditional or simplified?
traditional go with Hong Kong
simplified go with CHINA
find the main and fs corrresponding to each other for your phone
then find the CUSTPACK for chinese (APAC 1)

Okay.. Got That!
Thanks man!
