How to Flash
We are going to be using Odin in this explanation to flash the stock kernel to your phone.
First you are going to want to start by downloading all the needed files onto your computer and then place them onto your Desktop.
Once you have everything downloaded and on your desktop, you are going to want to first install kies.
After this is done you should restart your computer for proper driver installation.
Next, extract Odin to a new folder on your Desktop. Leave the tar in the form it is.
Now, open up Odin by double clicking the .exe in the folder you extracted it to.
The most important step is now, you need to put your device into Download/ODIN mode so your computer will recognize it and be able to flash to it. To do this simply turn your phone off completely (or pull the battery). Then you are going to want to use the following button combination to force your device into download mode:
Hold the volume up/down and power button all at the same time.
Now ODIN should have recognized your device ( it may take a while for the drivers to complete installation so don't panic the first time).
Lastly, we want to click on the PDA button and then search for the SGH-T989-UVKID-Insecure.tar
we download earlier and placed on the Desktop.
If all of the above has taken place you are free to hit the Start button.
If all has gone well at this point the flash should be proven successful and your phone should reboot like normal.
If so, please feel pressured to give yourself a pat on the back, that was tough! :P
