Default Data Drops and cant find a guide that works. Help please

So I hope someone can help me out. I am still having data drop issues. I have tried 3 different ways to get this thing working with no luck. And under mobile networks if I have WCDMA/GSM selected it will drop and auto reconnect, but if I have the LTE one selected once the data drops it will not come back up.

I have re-flashed radios from the different guides on both a 4.2.2 rom and a 4.3 base TW rom. I have fallowed all the guides in the links below.

I am on a 4.3 rom
Bootloader does not list any knox info, so I assume I am on a 4.2.2 bootloader (is there any way to confirm)
Baseband modem 4.4.2 Current (Former 4.3)
LTE is 4.2

I have been fighting with this for the last few weeks and any help to get me out of this connection hell would be awesome.
