    Default Need help rooting Sprint S4 - SPH-L720T

    I just picked up the S4 yesterday from Sprint. I had the Sprint S2 and S3 previously and this is the first time I've ran into trouble with rooting. The main thing I'm trying to do right now is get it rooted and be able to use WiFi sharing. I used WiFi Tether previously on my rooted S2 and S3. Any help would be appreciated. Here is all of the information for my device, not sure what is relevant and what is not:

    SW and Baseband version read the same: L720TVPUAMK5
    Hardware version: L720T.03
    Model Number: SPH-L720T
    Android Version: 4.3
    Kernel Version:
    3.4.0-2099174
    se.infra@R0210-09 #1
    Build Number: JSS15J.L720TVPUAMK5
    SELinux status:
    Enforcing
    SEPF_SPH-L720T_4.3_0012
    Secure boot status: Type: Samsung

    When I got the device home I started looking around for root methods. I've always used the ones described here but for some reason I stumbled upon galaxyS4root.com. I attempted to root the device using the CWM method shown here: How to Root Galaxy S4! [CWM Method][GT-i9500][GT-i9505][T-Mobile][Sprint] | GalaxyS4Root.com.

    Everything seemed successful with the procedure, but when I got to the end and brought my device back up and launched Super SU, instead of updating the binaries it showed a message asking if I wanted it to attempt to disable KNOX. Being unfamiliar with KNOX I read up a bit and decided to choose yes to disable KNOX based on what I had read. It said it successfully disabled it but it never updated the binaries. I also could not get my root wifi tether app to work. I've tried a few other methods since then and none are working. As it sits right now I have root check which states that the device does not have root access. I do not have Super SU or Superuser on the device.

    When I go into download mode it reads the following at the top left:

    Product Name: SPH-L720T
    Current Binary: Custom
    System Status: Custom
    KNOX Kernel Lock: 0x0
    KNOX Warranty Void: 0x1
    CSB-CONFIG-LSB: 0x30
    Write Protection: Enable
    eMMC Burst Mode enabled

    When I go into Recovery mode I get the picture of the android guy laying on his back with the red triangle above the chest. The yellow text reads:

    # Manual Mode #
    -- Appling Multi-CSC...
    Applied the CSC-code : SPR
    Successfully applied multi-CSC.

    The standard Android system recovery options are at the top in blue.

    Again, I'm not sure what is relevant and what is not, but I'd rather put too much info rather than not enough. Normally I would just do a factory reset with the device kind of in limbo right now but I read a warning on the sticky Root thread here to not do that. Again, any help would be appreciated as I would really like to get this one rooted and be able to use it as a hotspot. Please let me know if I need to clarify anything. Thanks.

    Try flashing CWM again. Get into Download mode and use Odin to flash CWM, I am specifically looking at Step 5.

    The instructions in the link above is for the sph-l720 which is different than the l720t. I tried rooting my 720t with 720 files and bricked it. Lucky I could get to download mode and restore the stock firmware. You need to go to this link it works.... m.youtube.com/watch?v=ok6bBq3TRas&feature=youtu.be I used it it works.

    I was able to successfully root my sph-l720t earlier today using the towelroot method...I ended up voiding the warranty but it's definitely rooted, I was able to flash TWRP recovery as well. I've got the NG5 firmware.
