Alright. This is for everyone who wants to root their phone. I've seen MULTIPLE threads of the same question "Can I root my phone and How do I do it". So I hope I never have to see it again! In this tutorial, I use use my toolkit as the way to root. Doing it manually takes forever and that is why I made my toolkit.

Requirements:

HTC One S (charged to at least 70%)

Windows XP,Vista,7 (8 is not officially supported since I don't have the drivers)

USB cable

Ability to read and follow step-by-step

Understanding that I am no way guaranteeing anything. If you screw up your phone, you probably didn't follow my steps and made a foolish mistake.

Let's begin.

Download my toolkit from here.

Link 1 and Link 2

Extract the FOLDER to your C: drive or to your desktop.

MAKE SURE YOUR DIRECTORY DOES NOT HAVE A PERIOD OR SPACE.

Open One S.exe

So now you have my program open. Great.

On your phone, go to Settings -> Developer Options and Enable USB Debugging.

From my toolkit, Click 1. Install HTC Drivers.

After the drivers install, restart your computer.

After your computer loads up, open my toolkit and connect your phone to the computer. Your phone should now be recognized.

Now, click 2. Register at HTCDev. Register with a VALID email address and LEAVE the web browser open.

Now, under the commands section of my toolkit, press Boot into Bootloader.

You should have a nice, white, shiny screen that says FASTBOOT USB.

Click 3. Get Token ID. Look at the pop up and it will tell you how to get the Token ID.

Highlight where it says < < < < Identifier Token Start > > > > all the way to < < < < < Identifier Token End > > > > > and right click and it will automatically copy it.

Now, click Submit Token ID. Your web browser should now open a new tab. Scroll down and in the empty box, paste your Token ID. Press submit. HTCDev now emailed you your unlock token.

Your phone should still be in the bootloader. Now, go to the email address you registered to HTCDev and DOWNLOAD your unlock_code.bin. Press 5. Unlock Bootloader. Locate your unlock_code.bin and it will flash it to your phone.

READ the warning. THIS WILL WIPE ALL YOUR DATA FROM THE PHONE.

When you agree to it, press the volume up button and press the power button to accept it. Your phone will now restart.

When your phone loads up, go through the set up wizard. Then, on your phone, go to Settings -> Developer Options and Enable USB Debugging.

Under the Extras section, press Perm Root. It will push SuperSU.zip to your phone.

Now, it is time to flash a recovery. The custom recovery is for 2 different devices

TWRP (Team Win Recovery Project) is a custom recovery that will allow you to flash custom ROMs, Mods, etc.

If your phone is the S3 model, then flash the one that says TWRP (S3)

If your phone is the S4 model, then flash the one that says TWRP (S4)

If your phone is the special edition 64Gb model, then flash the one that says TWRP (Special Edition)

After it flashes, remove the USB cable and have HBOOT selected in bootloader. Press the power button and it will reload to another screen. Press the Volume Down button until you get to Recovery. Press the power button to select it.

Go to Backup and back up your boot and system partition. Always have a back up before you flash or do anything.

After that, go to Install and locate SuperSU.zip. Click it and slide the screen on the bottom to flash it. After it flashes, reboot the phone.

In your app drawer (your menu with all the apps), open SuperSU. If it says the binary needs to be updated, then update it. If it doesn't, then you are fully rooted!
