There is currently a working method for the SPH-L720 S4, but none as of yet that I know have developed for S5.
You'd think similarities would allow it to be done, but the model previously is what caused some of the issues.
Accessing the service menu is vital and it previously was believed to be inaccessible without downgrading modems.
But I found a thread showing how to access it. Here's the S4 forum: forum.xda-developers.com/showthread.php?t=2530610
here's the method to access service menu:
Dial *#0011# and then hit:
==> [MENU] + [Back]
==> [MENU] + [Key Input] + "Q"
==> [MENU] + [Key Input] + "0000"
==> <wait ~5-10 seconds>
