Sent from my SM-N900T using XDA Free mobile app
First go to http://SamMobile.com
and download the official Samsung
Tmobile N900T 4.4.2 NF1 stock firmware.
If you still have a custom recovery like twrp or cwm boot the phone
into recovery and do a full wipe including Data, System, Cache, Dalvik
cache and last but not lest do a factory reset.
If you no longer have twrp or cwm custom recovery then simply boot into
stock recovery and perform a "Factory Data Reset".
Once all the above is done open Odin and put the official stock firmware
into Odin's PDA/AP slot & boot your phone into Download Mode, connect
the usb cable from the computer to the phone.
At this point the "COM:xx" should light up in Odin.
(don't change any settings in odin.)
Once it lights up click START in Odin and let the phone flash the firmware.
Once odin is done flashing your phone will reboot, have patience, it can
take up to 5-10 minutes before the phone is fully booted & ready to use.
After the above is completed successfully your baseband will be NF1 not NB4
and your phone should be working properly.
