I am new to the Android World and now own an M003 (ordered Rockchip but this is what I got) and want to replace the fonts so it displays Thai correctly, instead of little boxes. I downloaded the fonts but I don't understand how to root the device and replace the fonts. If someone could give me a quick tutorial with step by step instructions I would appreciate it very much. Can I do it over WiFi or do I have to use the USB cable? I have downloaded ADB to my PC and am running Windows 7. Thanks in advance.
