I have spent most of the day searching the internet trying to find a download for Thai OS and Current Firmware 3.90. Is the OS and firmware the same thing? I am only looking for one product? If the firmware included with TSM 10.1 with JCV? Would the Thai keyboard be included with the firmware. I have a 205w purchased in the US.

Does SG/MAL firmware allow you to use all of the features of TSM 10.1? Can I use it as a replacement for Thai firmware?
