Hi. I bought my N900 about a month ago in Hong Kong, and when I bought it, it could input chinese and had the virtual keyboard thing. However, I changed the device and text input language back into English after coming back, and now I cannot use the virtual keyboard, nor can I write Chinese text messages now (even in Chinese text mode). Please can I get some help? I tried the different methods listed in odler threads but nothing seems to work.

How or what, exactly, did you change? I have a HK model too, my Settings>Language & Region>Device Language is set to English (United Kingdom). Settings>Text Input>Hardware keyboard layout is English, Nederlands. I have no problems entering English or Chinese.

That doesn't function anyway if you have SCIM (ie Chinese Input) installed.

Detailing exactly what different methods you have tried would help. Or you should have posted your problem onto those older threads instead of starting a new one.

I've sent the solution to this problem to all the threads and i'm sending it here also..I'll go through it step-wise..
1: Open application manager and go to uninstall
2: Uninstall MSCIM or SCIM that you have
3: Open X-Terminal
4: sudo gainroot
5: cd /etc/event.d(There's a space after 'cd')
6: ls
7: After 'ls',see if 'scim' is there in that list that comes up,if its there just remove it with the following command.I'll just write it as '8'
8: rm scim
Now type '9' and '10' exactly as i do,
9: /usr/bin/gtk-query-immodules-2.0
10: /etc/gtk-2.0/gtk.immodules
Even if '10' doesnt work,taking care of step '1' to '9' should make the virtual keyboard work.Let me know how it went..
