2. Look at the top left corner of the screen, you will see the keyboard symbol. Type on that and then you see 'international keyboard'. Click on Chinese. When in Chinese mode, click on language (CN) and put in English.
3. Now you have the T9 keyboard back on 4.3!
The other thing to note:
1. If you upgrade directly from 4.1 to 4.3 via PCC, not flashing an .FTF then you should still have the keyboard. But, do NOT untick the T9 keyboard option in message settings or repair your phone if you want to keep the keyboard.
