These instuctions are based on using a rooted Sprint Mega SPH-L600 running android 4.4.2 and using Philz Recovery. I did not have much luck getting TWRP to work on this phone.
1. Backup your current rom as I will not be held resposible if your phone breaks or bricks or anything else. You use at your own risk.
2. DL MegaMix Theme Rom to phone.
3. I have dirty flashed and clean flashed and I have no problems either way. If you dirty flash just go into recovery and install zip. If you clean flash I would go to recovery and go to wipe data/ factory reset and then click on wipe data / factory reset again and then install zip and then reboot. I would not pick clean to install a new rom because this is not a new rom. This is the stock themed rom and I am not sure what would happen if you did. Like I said I have dirty flashed many times and no problems. When phone first boots up after flashing be patient it may take several minutes to boot up. Also if you get google + error just tap ok a few times until phone boots up and then you will see the option to update google play service in status bar. Make sure you do update and all should be good.
4. After running if you see something that needs to be looked at or you would like changed I can't promise but you can ask and I will do the best I can.
