blah - the reason why they haven't released any FW with Japanese on it is because they don't use these phones in Japan. It would be completely pointless for them to make a FW for japanese if its only for people like yourself and not a whole country or region.

peymann609 - you can either use the steps i have stated in the first post of this thread, or you can just flash your phone with a new FS. Both should work. Either way your going to have to use a FS that has farsi on it. (M EAST N AFR or S_ASIA_LEVAN FS should do the trick. Just make sure that they are for your R1KG001 firmware.)

phantom13 - If I remember correctly that was the error you get if you haven't installed the usb drivers. I know they are floating around somewhere but not exactly sure. Or you can always get it by using the Sony Ericsson Update Suite.
