Sprint is not bootloader locked unlike AT&T and Verizon which the developers up to now are still finding ways to permanently root Note 4 on Sprint.
This article will show you the very easy process.
Go to your gadget’s Settings > About phone > Build number. Tick it a number of times until you see ‘Developer mode has already been turned on’ appear on your screen. Next, go back to Settings > Developer options > USB debugging. The box beside should have a check mark.
If not, just tick it.
You must have PC on this process. First is you have to make sure that you successfully connect to your PC. By doing that, the flashing will go fast and smooth. To do it, download your Sprint SM-N910PZKESPR USB Driver or Sprint SM-N910PWESPR USB Driver and install it. After that, connect your gadget and it will now be recognized by your PC.
Copy and paste SuperSU zip file to your gadget’s internal storage. Remember not to extract it. Also, copy and paste Custom Kernel to root Note 4 Sprint (for SM-N910P only) there and not extract it too.
Unplug from PC and enter Download Mode. Shut it down. When the screen turns black, press Power, Home and Volume Down button together. The warning screen should appear. Now, press the Volume Up button to continue. If you are not familiar on what is happening on your screen, that is what the Download Mode looks like.
Extract the flashing tool Odin3. Run it as administrator then connect your gadget to your PC. There should be a highlighted block with ‘COM’ written on it, located on the top part of the application. It just shows that you are connected properly. If not, you could remove your USB cable and reconnect. If it is still not working, transfer USB cable to another port, or reboot your PC.
‘Auto Reboot’ and ‘F. Reset’ boxes should be checked. Choose the AP/PDA button and load Team Win Recovery Project tar file. You are then ready to start the flashing. It will eventually reboot. But keep in mind to enter Download Mode immediately once it turns off. Press and hold the Power, Home and Volume Down buttons right away. It will now lead you to the TWRP mode or simply, the Recovery mode that is now ran by TWRP.
You need to back up the stock firmware you had in case you will need something from it. Tap ‘Backup’ in TWRP mode. Tick the ‘Boot’ box only. That selection is your stock firmware. Now just continue and swipe the slide below to back up.
It’s time to install the Android 5.1.1 Custom Kernel that you transferred in Step 3. In the TWRP menu, tap ‘Install’ and locate the kernel zip file. Swipe the slide that will appear below to continue the flashing. And there you go, you are now running a custom Android 5.1.1 Lollipop kernel. You really need to use a custom kernel instead of the stock ones because it lets you do the bypassing and overwriting.
When your gadget already turns on, you should now be able to see a SuperSU app installed in it. Open it and just grant if pop ups ask to overwrite binaries. Then download Root Checker from Google Play Store. Install and launch it to verify.
Bravo! You should now see that your Samsung Galaxy Note 4 Sprint has already gained root access! You can now take control over your RAM, processor, battery life, and purchase apps without having to pay its price! And, just so you know, there are apps available just for rooted gadgets. Feel free to enjoy them now that you have full control over your gadget!
