Is this the preferred method to root a T-Mobile Samsung Galaxy S3 T999
Android 4.3 Jellybean USA phone?

I have never rooted a phone before, but I want to test out Titanium backup,
so I went through the rooting motions just now to test out the procedure.

Almost all instructions suck, so when I went through the motions, I
modified the instructions to be clearer on the parts which confused me, so
the note below is an original, although 95% of it is based on the framework
found here:

How to Root T-Mobile Samsung Galaxy S3 (SGH-T999) on Android 4.3 Jelly Bean
---------------------------------------------------------------------
Requirements:
a. Windows computer with USB drivers installed
b. Fully charged T-Mobile Samsung Galaxy S3 SGH-T999 with USB data cable
c. CF-Root zip package
http://download.chainfire.eu/234/CF-Root/CF-Auto-Root/CF-Auto-Root-d2tmo-d2tmo-sght999.zip
d. Odin3 v3.09 Flashing Utility (note the version available is 3.10)
http://androidcentral.us/2013/11/download-odin/
e. Optional: QuickHash for Windows XP
https://sourceforge.net/projects/quickhash/

Phone:
1. Settings > More > About device > (repeatedly tap) Build Number until it
says "you are now 4 steps away from being a developer".
2. Tap developer mode 4 more times until it says "you are now a developer".
3. Enable USB debugging on your phone by the following options:
Settings > More > Developer Options > Debugging > USB debugging (check
the box)
It will say:
Debugging mode launches when USB is connected.
Allow USB debugging?
USB debugging is intended for development purposes only.
It can be used to copy data between your comptuer and your device,
install applications on your device without notification, and read log
data.
Press "OK".

NOTE: To turn off developer mode in the future:
Settings > More > Developer options > (slide the green slider from
ON to OFF)
You may need to click "Revoke USB Debugging Authorizations".
You may need to go to apps > all > settings > Clear Data.
Some say you may need to also do a factory reset.
4. To verify root access later, open the Google Play Store app on your
phone and install "Root Checker" by "joey krim".
https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck
Use "Root Checker" to confirm root access.
5. Install Titanium Backup root freeware:
https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup

Windows PC:
1. Extract CF-Auto-Root-d2tmo-d2tmo-sght999.zip to its own folder

2. Extract Odin v3.09 files to its own folder

3. From the Odin extracted folder run Odin3-v3.o9.
4. Reboot your T-Mobile Galaxy S3 into Download Mode:
a. Turn Off Galaxy S3.
b. Simultaneously press & hold the three buttons "VolumeDown+Home+Power"
until you see a warning on your screen.
When you press the buttons, within a couple of seconds, you'll feel a
buzz & the green, white, & yellow message comes up:
Warning!!
A custom OS can cause critical problems in phone and installed
applications.
If you want to download a custom OS, press the volume up key.
Otherwise press the volume down key to cancel.

6. In the Odin GUI, make sure that only "Auto Reboot" & "F. Reset Times"
options are checked.
(Leave the rest of the options off, which are the default settings).
7. In the Odin GUI, click the PDA button and from the extracted folder
select the CF-Rooted kernel file and hit the START to flash the kernel.
8. Wait for Odin3 to complete.
9. When completed, Odin will notify you via the PASS!! message in Odin and
at this stage your phone will automatically reboot.
10. Once normally booted, check that SuperSU has been installed.

a. Now you have full root access to your phone.
b. You can also install apps which require root access.
c. You can get rid of the stock apps (using the Titanium Backup app).
d. If you?re planning to install a Custom ROM or Mods then you want to
install ROM Manager, which will then help you to flash Custom Recovery,
TWRP or ClockworkMod, depending on your choice.

The problem with this method is that the instructions are older than the
software, so, the buttons don't line up nor do the file versions.

Also, my USB port is kaput, so, no root method that uses USB wire will work
as shown here with both a flash drive and the phone hooked to two USB ports
(where only the flash drive shows up).

Nonetheless, I honed the instructions for the next person to benefit from:

I solved the problem by rooting without needing a USB cable or computer:
https://u.cubeupload.com/ccNUuE.jpg


In a search, I found this "kingoroot" app:
http://i.cubeupload.com/HY1E6B.jpg

I downloaded the kingoroot APK (which is just a ZIPped installer):
http://i.cubeupload.com/uleVfF.jpg

Then I tapped on the APK file to run the kingoroot installer:
http://i.cubeupload.com/Z4uCU6.jpg

That installed the "kingoroot" app:
http://i.cubeupload.com/GxVyyC.jpg

Here is the kingo root app organized in my system folder on my one desktop:
http://i.cubeupload.com/XRjvkP.jpg

I tapped on that Kingoroot app and this came up:
http://i.cubeupload.com/CJlJEg.jpg

I pressed the button to root the phone, which took about 90 seconds:
http://i.cubeupload.com/9Sd1TC.jpg

I started getting scared, but I soon saw a message "root succeeded":
http://i.cubeupload.com/nlIV1u.jpg

To confirm I had root access, I started a separate root-checker app:
http://i.cubeupload.com/9qx4JW.jpg

That root checker app confirmed I now had root access:
http://i.cubeupload.com/DG7PjD.jpg

Then I ran the Titanium Backup free app (which requires root access):
http://i.cubeupload.com/OQHqGv.jpg

And voila! I can now backup my phone to an sd card, to an internal
partition, to a computer, to the cloud, whatever!
