As soon as the file is loaded, you should see a pop up, prompting you to connect your device to the PC in Flashmode. Now, turn off your device, and connect to your PC using the original data cable while keeping the Volume down key pressed. This is for flashmode.
After you’ve connected your device successfully, the Flashing will start, wait and sit back while the flashing gets completed. You should see the logs now, as soon as it is done the ”Disconnect and restart your phone” will appear at the bottom. Now just Disconnect your phone and restart your device.

If any one have Battery drainage problem:
Some of the people were complaining about battery drainage. The root cause of this is related to the latest version of Google Play Services (4.4.52). Until a new version of Google Play Services is provided by Google either uninstall the latest update of Google Play Services (might limit use of Google Services like Youtube) or go to Settings > Google (accounts) > Ads > Tick the box for Opt out of interest-based ads and also disable back up of your data by going to Settings > Backup & reset (Personal) > uncheck the box for “Back up my data”.
If you are unable to uninstall the update for Google Play Services from Settings > Apps, go to Settings -> Security -> Device administrators and disable “Android Device Manager”. Also check the settings in the Play Store so that automatic updates is not enabled as this may update Google Play Services again automatically.
About the Torrents files:
Also, I would like to notify you that the download link to the torrent is not from me and is provided by Flashtool.net . I have seen the issue with C6606, when you download the file it says it is for C6616. I don’t know if it is really for C6616 or C6606, but as to my knowledge there is not much of difference. I would like to ask you readers from T-mobile from US to make a ftf file for C6606 and upload it to some website and provide the link to me in Comment box. So that it will be useful for others users also. Is there anyone who could help me?
