    I got the ":-(" sign too trying to install the 10136 update. I tried several solutions, nothing worked. So i flashed the default ROM. But try these steps first:

    Solution 1. Lumia software recovery tool
    Solution 2. Hold "volume down + power" until the phone vibrates. As soon as it vibrates, let go of the power button only.
    Solution 3. If all else fails, try flashing the ROM. Follow the link:- [Tutorial] How to flash an Lumia device | Windows Phone 8 Development and Hacking | XDA Forums
