Many thanks and good comment.
I tried out the staff and downloaded the HK gov 3.x MB chinese font.
The screen go black with a cross-pointer at the center when boot up.
It hang up after long time.
Any one got some working fonts we can use?
After I reflash my iLiad, I got bad experience.
First the reflash file is only 2.10 and then it is buggy to input the network settings and re-download the patches to 2.11. This takes more than 30mins.
But one strange thing appears that the chinese feature on my iLiad disappear.
Because I once saw the iDS said downloading chinese font when I first purchased and connect to iDS.
This means iRex actually can provide and support chinese or other language characters.. any comment?
My total experience for iLiad is that the software has too many issues and no usefully technical support for iRex..
Many thanks to the community people. I'd like to write up a solution after i got through all the pain.
