huh? there are some posts missing.
Anyway, just an update...
I had flashed my TP 2 to Energy ROM Cookie 23xxx version. Then I just did as per Bro gromky instruction there and still failed.
But then, I've installed myself QQPinyin this time and guess what, this time it actually works for QQPinyin for not messing up my qwerty keyboard again by switching the layout to 简体中文 (which didn't help last time)。
So, any idea on why this is happening? Anyway, I'm so glad that I can type chinese font this time again.
Thanks Bro gromky
