According to the official specification from xiaomi, there is 3 system languages of mi-box which are English, Traditional Chinese and Simplified Chinese. But they preset it to Simplified chinese and then remove the settings.apk. I found a compatible one instead. (Cap38) It works. Furthermore, I add a moreloacle.apk for multi-languages purpose.(cap40-41) It seem to be work also. The final problem is the built-in SDcard. /mnt/sdcard/ Xiaomi made it inaccessible. Why? due to policy? God knows!! So you often need to use OTG port for storing data. Amazingly, 1T Toshiba Portable Hard Drive works without external power supper.(cap45) External sdcard located at /mnt/usb/sda1 Actually, I often watch some huge file from my computer which is easy to share by microsoft windows network(fig.4 and 5). ...(to be continued... keyboard not working? how to change IME?.. browser can not real flash? xbmc problem? all are coming soon) Hey guys.... have any question, please feel free to contact me. I wanna share what I did...don't waste anything.....GREEN!
