[Sprint Samsung Galaxy Note II] mrRobinson:
This is a root injected FACTORY Stock L900VPALJ1 Odin Flashable Image. You flash this in Odin just as you would the completely stock ROM from samsung. I've simply injected the su binary and SuperSu app so you now have rooted stock image.

So if you want to keep your device stock yet have the functionality of root without tripping the counter or messing up OTA updates then this would be your best bet.

You can get ODIN here

and the drivers for the SPH-L900 so ODIN can detect your phone can be found at Samsung's site. Click on the Manuals & Downloads tab at the bottom and then on Software for the latest driver.

Instructions:

First, Download Image:

New Full Rom VPALJC

Mirror 1: root66_SPR_L900VPALJC.7z

Orig Release JB 4.1.1

Mirror 1: root66_SPR_L900VPALJ1.7z

Mirror 2: root66_SPR_L900VPALJ1.7z

Second, Extract and Flash:

Extract the root66_SPR_L900VPALJ1.tar.md5 from the .7z file you downloaded.

Use Odin, put phone into download mode [with phone off, hold vol. down + home + power ], connect to computer and open Odin.

once in odin click the PDA field and select the root66_SPR_L900VPALJ1.tar.md5 you downloaded.

Leave Auto Reboot and F. Reset Time checked.

click start and

when done let phone reboot.

If you have issues flashing with Odin please ensure you are using the microusb cable that came with the phone, users have had issues using other cables.

If you just want a stock, rooted phone with no custom recovery, no plans to flash custom roms, etc. then you can stop HERE.

OTA Updates:

Stock Recovery:

Once rooted with above method, if you receive a notification for an OTA update, it has been verified you can use OTA RootKeeper to retain root through the update process.

Non-Stock Recovery:

If you have loaded a non-stock recovery (per below) you can simply use it to flash the OTA update flashable zip I've created.

Mirror 1: OTA Update LJ1 to LJC

Mirror 2: OTA Update LJ1 to LJC

Optional, Recovery (will trip counter):

It seems loading any custom recovery will trip the download mode flash counter. Loading a non stock recovery will also prevent you from successfully applying any OTA updates however here is a procedure for any who want a non-stock recovery:

Currently I see TWRP has support for this device so the instructions here will install that recovery.

Option 1: Download GooManager from the Play store. Once installed click the menu and select "Install OpenRecovery Script".

Option 2: Download the TWRP recovery image here. Copy it to the /sdcard of your phone.

Connect your phone to your computer and use adb

type adb shell

once in the shell run su

then

dd if=/sdcard/openrecovery-twrp-2.3.1.1-t0ltespr.img of=/dev/block/mmcblk0p9

Alternate if unfamiliar with adb commands

Grab android terminal emulator from the play store and run the same commands starting with su and then the dd command.

De-Bloater

If you've made it this far with a stock, rooted phone with CWM or TWRP and you don't want to flash a custom rom (which will do its own de-bloating) you can check out my mrRobinson Note II De-Bloater to easily get rid of bloat system apps you no longer want to see. Simply flash in CWM or TWRP like anything else and you will be presented with a menu system to choose what to remove. If you are unsure it is safe to pick Minimal and still get a decent de-bloat.​

History:

I've injected root into other stock images and those threads have a lot of valuable information which could answer some questions that may arise here. If you have time to do some reading here are a few of the informative ones:

Samsung Galaxy S3 [ATT / Bell / Telus / Rogers / Sasktel ]

Samsung Galaxy S3 [TMO / Wind / Mobilicity]

Also did sprint and vzw but there isn't much there that won't be covered above.

FAQ

Does this remove the Sprint bloatware?

A: No. It is same as stock, nothing is removed.

Does this use an unsecured boot.img

A: No. This flashes the stock boot.img in the VPALJ1 image.

If my flash counter has been tripped, and I flash this and reset the counter, will it stay at 0.

A: Yes, as long as you don't then flash a non-stock recovery.

Can I still get OTA updates?

A: Yes if you do not load a custom recovery or remove any system apps OTA updates will still come and be able to be successfully applied. If you want to retain root through the OTA process I'd recommend trying the SuperSU survival mode.
