Root Method (could possibly work?)

Once again, I switched from my n910a to a n910t3, but I still have the n910a. But I've still been browsing around to discover that some people "Change" their sprint phones to tmo, by using the csc, and cp files (not the AP or BL.) So would it be possible to take the kitkat files of tmo or sprint phones and install them on the att phones? Like if are a rooter out there, you know what I'm talking about and I've done this before and I've been able to do some cool stock rom customizations that I didn't need to I revrrted. So if we could use this to somehow get root in through the csc or cp, and then use safestrap to get a custom kernel and bootloader, and then wipe all the att p00p off of the phone and essential making it a "tmobile" or "sprint" phone with the model of n910a. If ur a pro, you know where I'm getting at. And has the root de la vegla method been tried yet? Combining both methods? The vegla method I remember was used to root the att note 3, and it worked for me, and I got super su as a system app, but then I installed cwm from the phone using flashify, and it gave me the system software unauthorized by att and I fixed it using the files @getyrocks posted. Shout out to him and thanks. If 6ou know my other post with 8k+ views now. @getyrocks have a look at this post and tell me where I'm right and where I'm wrong. So yeah, was wondering if we could use this as a root Method for the note 4 att /verizon or any att/verizon/samsung phone..
Thanks guys
