Want to SIM unlock and root my Sprint SGS4 - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Hi guys i jave a Sprint SGS4 which i was reading can be unlocked and rooted.
My phone info is as follows:
-------------------------------
Software version
L720VPUFNAE
Hardware version
L720.08
Android version
4.4.2
Baseband version
L720VPUFNAE
Kernel version
3.4.0-481102
Build number
KOT49H.L720VPUFNAE
Secure boot status
Type: Samsung
Security software version
MDF v1.0 release 2
Model number
SPH-L720
ICCID
unknown
Device status
Official
---------------------------------
So my questions are as follows:
1- how can i SIM unlock my US Sprint SGS4? If possible can you provide a step by step or link to a guide?
2- which 1 must be done 1st, unlocking or rooting, or it doesnt matter?
3- is it possible and how can i root my phone in a safe way? is there a guide to return back to stock?
4- what or which is the best and safest/stable custom recovery?
If you guys need more info about the phone feel free to ask, i will reply as soon as i see the question. Cause i have been looking all over the net for this info/guide but could find anything conclusive cause it all point to a firmware my phone doesnt have so i dont know what to do and theres an OS update pending that i dont want to install yet which i think is 4.4.4 at the least.
Thanks in advanced, and have a nice day!
Hope to hear answers and guides and links soon.

Noob Here Needing Some Pro Advice

So my friend told me to root my new Samsung Galaxy Note 3 (Verizon), but I am a complete noob and do not want to mess up my new phone.
He told me to be careful so I don't brick my device, and too read the forums. I have spent all day reading the forums and still don't know what I should do.
I saw a video explaining how to get root by going to towelroot.com, but this seems too easy to be true and safe.
Can I get root and not have to worry about bricking or tripping knox with towelroot?
If towelrool is ok to use then I will just go ahead with that, but If there is something better, could someone please point me in the right direction with what I need to download.
Thanks for any help and here is some of my device info if that helps...

For those of us who took the OTA, ... That app http://towelroot.com/ is the only exploit that provides root access for VZW N3.
yes. i am going to sound confusing now so hold on...Towel root is what it is... download. install. click.. your phone will reboot with root access ... it is a one click method... however, the bootloader and recovery is still locked on your device, and if you try to install CWM or TWRP, at this time you will trip KNOXX and void your warranty. Install SafeStrap instead from here : http://forum.xda-developers.com/showpost.php?p=53701934&postcount=1298.. then flash only one other file from this post http://forum.xda-developers.com/showthread.php?t=2760380 thanks to the DEVs that have been working on this the whole shebang seems almost too simple, like you said... i agree.. i did everyrthing in that post as i installed Jasmine Rom. why? because the DEV is kickass, with the updates, i like the S5 themes, and its pretty simple to set up compared to what you've probably read up on..
and its really close to stock, which, of course, ive tried out a couple of other roms since then, and it still works (the phone)
Regarding KNoXX , your device will still read 0x0 , but it will say "custom" status .. you can fix this
if you root your phone and your status says "custom"..a flashable zip file here will fix that http://download.chainfire.eu/supersu you can find links to Safestrap, "unified files" and step by step instructions at http://forum.xda-developers.com/showthread.php?t=2760380 some more on what i mean by "custom" http://forum.xda-developers.com/galaxy-s2/orig-development/2014-01-15-triangleaway-v3-26-t1494114 This does the same , maybe better http://forum.xda-developers.com/showthread.php?t=2473938
Towel root will not "hard brick" your phone ,,, meaning your phone is basically an expensive paperweight... ii gave you thseds links because its what worked for me... however, you know whats best for you..

[Q] Note 3, impossible to custom rom?

I must be terribly impatient or not understanding what I'm doing, probably both actually but I cannot for the life of me find a working method for loading a custom rom on my phone. Could someone PLEASE point me to a resource that will work for my phone? Info provided below:
Samsung Galaxy Note 3
Provider: Verizon wireless - USA
Quoted info from settings > About Phone:
Model number: SM-N900V
Android version: 4.4.2
Baseband version: N900VVRUCNC4
Kernel version: 3.4.0 [email protected] #1 MON April 28 16:42:37 KST 2014
Build number: KOT49H.N900VVRUCNC4
Hardware version: N900V.07
Security software version: MDF v1.0 release 2
I have root access thanks to towelroot
I have supersu as well. Every guide I've found for different rooms has been busy. I've only tried safestrap methods because I know I can switch back to the stock rom slot and have a working phone again. Im weary of methods that wipe out the stock rom as I really don't want to end up with an unbootable brick.
Ive tried cyanogenmod, and a TouchWiz room who name I can't think of at them moment. Both roms simply booted to a black/blank screen.
I really like the simplicity of cyanogenmod and it is my preference but I'm open to others. Can anyone please advise me on my options please, I've about reached my words end here. Why must these companies make it so hard to make the devices we pay hundreds of dollars look/act/be the way WE want them to be as the now owning consumer?!?
Thank you for your time, help, and guidance, I have nothing but respect for all the developers in this community, wish I understood the system better so I could be of more help as well.

Do we need NC 2 and how would we install it?

I'm in a similar sitch. I have rooted my phone after the NC4 assault using towelroot. Note to those who plan to use it: there are some hijacks out there. Don't go to towelroot.net for example. I have downloaded a couple of safestrap apk files and have been reading up on how to install safestrap. Once installed, then what? I think I need to install the NC 2 kernel but how? What's a kernel anyway? How is flashing a kernel different from flashing a rom? How is an android kernel different from a linux kernel? I can't see a way to run linux commands anyway...
Hi guys! There's a ton of guides on the forums that answer your questions. If you need help you are best of posting the exact steps you took up to that point and at what point you are stuck. Wikipedia also has a ton of information on the basic computer science stuff (what's a kernel? etc...)
Good luck

There is this new rooting tool [Towelroot] that works perfectly, you may try it, it does not need PC connection and its free. https://towelroot.com/

Hi mate ,
phone info is a great app...the link you posted is for the official stock rom for the I9505 ( UK) , 100% original , if you flash it you will be back to stock ( recovery and firmware) , the only thing it will not be reset will be the knox bit ( warranty) if you flash a custom recovery or custom rom the knox bit will be set , if you rooted with towelroot it will not be set

The root methods you have listed are intended for older versions. The only functioning NC1 root method is towelroot. Please check the all things NC1 thread prior to posting. All info can be found there. The person above has given the link to towelroot. If you go to the galaxy s5 forums, you can get a tutorial on it, but it's pretty straightforward. Enjoy your rooted device.
Remember that the phone has a locked boot loader. So, the stock kernel and recovery cannot be replaced. The only working recovery is safestrap. There is also restrictions on the Roms that can be flashed.
