Method 2 - Using Odin

Download Odin 3.07 from my signature

[*]Download Chainfire's Triangle Away to your

External

SD Card (

Thread

)

[*]Download and extract

Stock System + Root

[*]Download

Stock Recovery

[*]Download

Stock Kernel

[*]Open Odin

[*]Reboot Phone into Download Mode. (Power + Home + Volume Down, Then press Volume Up when prompted.)

[*]Once in Download Mode, connect the USB/Charger cable to the phone and plug into the USB port on your computer.

[*]You should now see a COM# port listed toward the top-left of Odin (under ID:COM)

[*]Click on the PDA button in the middle-right area of Odin.

[*]Browse to and select the Stock System you downloaded

[*]Make sure Auto-Reboot and F. Reset Time are the only options checked and that PDA is the only other thing checked.

[*]TRIPLE CHECK your settings and that you have selected the correct firmware for your model phone and are using the correct options.

[*]If you are using a laptop, make absolutely sure you are plugged in, or if on battery, that it is charged enough and will not go into sleep mode during flash.

[*]Click Start to begin the flash. This can take a few minutes, so be patient!

[*]Once complete, in the top-left box in Odin, it will say PASS and the phone should have automatically rebooted.

[*]You may unplug the phone and close Odin if you wish.

[*]Wait at least 5-10 minutes for the system to boot the first time and then build its cache! (It may seem to hang during boot, this is normal and you must be patient!!!)

[*]If the phone still hangs during boot up, hold the power button down until it shuts off, quickly release power and then Immediately repress Power + Home + Volume Up. This will boot recovery. Now Factory Reset and Reboot.

[*]Follow these same steps again for the Stock Kernel and Stock Recovery you downloaded. (Note: You can alternatively now replace all 3, System, Recovery and Kernel, with the official root66 firmware!

root66_TMO_T999LUVAMB7.7z

)

[*]DONE!!!

Reboot Phone

Install Triangle Away and reset the flash counter.

Reboot and check Triangle Away to see if it still says the counter is at zero.

Now, to unroot, open SuperUser/SuperSU (app)

Find and select the option to Permanantly Unroot (Full Unroot or similar)

Reboot

Next, if you want a 100% clean, out of the box type device, reboot Recovery.

This should take you into the stock recovery you just flashed. Now Factory Reset.

This will wipe Triangle Away as well as your Internal SD Card.

Your phone should now be exactly as it was when you powered it on the very first time!
