Got Chinese Input on my Verizon Storm II 9550
Had to use several software version (9550/9520/one other BB non Storm Model's Language File) and install COD one by one.
I now have Version 320/306/190 mixed, and so far so good
Simplified Chinese/Traditional Chinese/HK Chinese Input Methods
Tested Traditional Strokes method / Taiwan BoPoMoFo Input method / Wubi Input Method in both Traditional and Simplified ---- worked fine. Could not test ChangJie --- don't know how to write Chinese that well, did not test HK input method --- don't speak Cantonese well.
I wish I can post a clear instruction on how to do this but I can't because I've tried so many different ways that I am so confused at this point to say what to install first what to install second.
Here's the general rule, load Verizon 9550/320 first, get everything you want installed (extra applications) then back up all the files with Desktop Software or BBSAK, then get 9520/306 or it may even work with just 190 which was what I did the first time I got it to work except I wanted the extra things that came with the 9550/320 so I wiped the device and couldn't figure out how I got it to work in the first place.
Do not use the Desktop Software to load COD, it will delete all the Chinese Input methods. Use BBSAK.
Good Luck !!
