Hi, I had to post this problem because I couldn't find any satisfactory answers anywhere. I updated the Kies to the latest version, and it detected the mobile only after I removed the SD card. That's perfectly ok, and the popup notifying me that a new firmware upgrade is available came up. But when I start the upgrade and the firmware update process starts, suddenly a window pops up saying that "Firmware Update has stopped working". I work on Win 7. I don't want any solutions saying to flash my mobile, please. I want the official update to work. Please help me out. Thanks in advance.
