    Hi, the link of the driver/flashboot package is outdated and removed. Would you update it please?

    • Viraj SK

      Link updated. Please check..

      • Seithan

        Thank you. Bloody hell, one more time that it wont accept the driver. Windows 8 and no freaking way i can update the “unknown” fastboot S1 device with a driver, it simply ignores it as irrelevant. Wtf to do?
