Go into Recovery Mode and factory reset (you will lose everything that's in your Internal Storage but everything in your SD Card will be safe). Afterwards, reboot and let it sit there for awhile until you're prompted with a Welcome Screen. If for some reason you cannot get passed your boot screen, you must also flash a modem that is compatible with 4.3+ (I'm using the T999UVUEMJ4 modem).
After you have done all that, let it sit there for a good 10 minutes and reboot. After setting everything up, go into your Play Store (if you don't have the Google Play Store, go back into recovery and flash a 4.4 GAPPS) and download GooManager. Run the app and press the menu button and select ' install openscriptrecovery.' Follow the procedures and it'll automatically install the latest recovery (it should be TWRP (Team Win Recovery Project) 18.104.22.168). Reboot back into recovery then do a clean wipe and flash your ROM follow by GAPPS. Reboot and let it sit there until you see the Welcome Screen. Once you do, let it sit there for 10 minutes and reboot.
