Just checking... I got the kit kat OTA update and now Im thinking of rooting. Does this root method still work? How about the free native hotspot? Thanks

No, when you root your phone with CF-Autoroot, the knox warranty flag will be tripped and show 0x1. There is no way to reset this at present. The flag is tripped when a custom recovery is installed and CF-Autoroot momentarily installs a custom recovery to accomplish root. The Safe Root program works for 4.3 based phones and does not trip the knox warranty flag. Safe Root works for the 720T.
I just picked up the Sprint S4 and it is the 720T. I already attempted a method that tripped the flag. There was no warning regarding the 720 vs. 720T. I haven't had any rooting problems with previous devices so my fault for not checking out all of the details. When I go into download mode I see KNOX Warranty Void: 0x1. So that ship has sailed for me..hopefully at some point there will be a way to flip that back.

As my device sits now, I'm wondering if Safe Root will still work? The only thing I'm trying to do right now is get it rooted so I can use it as a hotspot. I previously used WiFi Tether for Root users on my S2 and S3, but I haven't found anything concrete on root Wifi apps for the S4. Any help from anyone on both fronts would be appreciated. I have a post in another forum and haven't gotten much yet.

Here are all of my device details in case any of it is helpful:

About Device:

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
[email protected] #1
Build Number: JSS15J.L720TVPUAMK5
SELinux status:
Enforcing
SEPF_SPH-L720T_4.3_0012
Secure boot status: Type: Samsung

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.

Any help would be appreciated. Thanks in advance.

Always should check the phone name and what the root method is for. I always ask if there is something that doesn't match.

If you are on sprint, they won't care about your Knox flag. They have worked on many of my rooted, flashed, etc devices and they don't care. All they will do is flash it all back to current stock if they REALLY need to. Just don't break anything in firmware that you can't fix

@sandman515 - I have a 720T/MK5 and Saferoot worked fine on it. Don't know if anything you've done would matter though, as I've recently migrated from HTC-land and am still a Sam-Noob... :eek:
I was able to get it rooted with Saferoot. Unfortunately the main thing I'm looking for from root is the hotspot functionality and it doesn't look like there is anything out there yet for this device. Does anyone know of a solution yet for the 720T?

I do not know if it works on your model?? I've got the regular 720, used safe root then downloaded goo manager from the play store. Goo manager let me install a recovery that let's the mods begin

I booted from recovery just now and got an Android is Updating screen. It 'optimized' all ~170 apps and then 'finished booting'.

What does that mean? I was pissed and thought it was updating system and boot. I checked and still have mk2 and 4.3. Root checker still says I have root access.

I was scared. What was that? Is it because I wiped the dalvik cache?

Yes, you saw that because Android rebuilt the Dalvik cache files for your apps at boot time. Here, the term is "upgrading" is something of a misnomer, and I've always been puzzled as to why (someone at) Google decided to use that term.

I have never had a dalvik rebuild display like that before. All my old HTC phones would just show the boot animation whole rebuilding the dalvik cache

Odin's trials

I have a sprint s4, unrooted atm. My current issue regards the color of the status bar is not yellow but blue. I have downloaded the driver and made sure it was the most current version, and I have my phone is currently running on 4.2.2. I am not entirely sure what I am to do, i followed the video from the beginning of the forum and this is my only issue so far.
The file I'm using for the PDA has the file name: CF-Auto-Root-jfltespr-jfltespr-sphl720.tar.md5
