No, don't even try, YOU cannot flash the new firmware update. I would recommend using the over the air, OTA, upgrade or having someone assist you if you have rooted or otherwise modified the phone and need to pursue an upgrade outside of the OTA upgrade process.
To expand on my statement above.
You have a Sprint LS980 from the title of your first post. You never mentioned by name what you attempting to flash despite being asked directly. The concern here is that you are trying to flash the wrong upgrade. You have not indicated if your phone is rooted or if you have a customer recovery like TWRP or Philz CWM. Without knowing if you have the ability to do so it is impossible to recommend that you try.
You could have a completely stock phone and there would be no method or reason for you to flash an upgrade. You could be rooted and need to flash an upgrade, but may be trying to flash the wrong thing. Even if you have the right firmware to flash and need to do so you have not indicated if you are having any problems and do not seem to have the ability to communicate your current state to allow someone else to assist you.
