Default SPH-L720 Got Tmobile to work, but no data

Hey everyone, so the issue I am having now is I cannot get mobile data to work.

I've done the following:

Downgraded to MDC, Rooted w/ SACS and followed this guide partially

Awesome, wifi didnt work though. Someone told me to follow THIS guide because I had KNOX bootloader, so I basically updated to MK2.

No more SACS or ROOTed system, but Tmobile still works... awesome.

Now data..... I am trying desperately to get this to work but having a **** ton of troubles. I cannot use the *#0011# method at all and the original guide says to use prop editor and add a line, but the thread doesn't explain it well. I am going to google it now but wanted to make a thread to see if anyone else has had this issue.

Please and Thank you -

Sprint phones are not capable of getting T-Mobile LTE. They use different bands. Best is Edge.
