[Help][Urgent] Flashed wrong model files

So thinking I bought a Sprint Galaxy Note 3 (n900p) on Swappa turned out to be an international galaxy note 3 (n9005) which I didn't realize until I flashed the n900p bootloader and used the cf one click root method. I have twrp installed but my bootloader is for n900p (Sprint). What can I do to get the proper bootloader and files flashed as I don't want to brick my device by using the sprint unroot method incase it doesn't work? Main issue I have is my phone loses LTE when I go in a building but picks back up when I go outside. The default radio baseband is Japan and when I switch to USA get LTE permanently but cannot receive/send text messages. After a period of time on the USA radio band, I will lose all bar signals in my status bar and it will show up empty. Ideas?
