[Sprint HTC EVO 4G LTE] dkman123:
Step by step

I am also not a fan of toolkits, I prefer step by step, but since I had the latest OTA update my options were limited.

I tried rumrunner but it gave me an error, and since it's an exe I couldn't easily troubleshoot what was happening.

Then I tried WinDroid and it worked, so here are my steps (I know I'm missing a few little bits, but I tried to spell it out as detailed as I could recall the process. You can copy/paste the block into a notepad.

Optional:
Hard reset your phone (factory reset)
Turn the phone off
Hold Power and Volume Down
When phone comes up select Factory Reset (volume up and down change selection,

power button selects it)

=== install drivers ===
I drove myself nuts because "adb devices" only shows devices that are booted normally and

"fastboot devices" only shows devices booted into fastboot mode. I wanted it to show in

both, but it doesn't work that way.

So if the fastboot step below doesn't work you can try this:
Download HTC Sync Manager: [url]http://www.htc.com/www/support/software/htc-sync-manager.aspx[/url]
Install it
Uninstall HTC Sync Manager, but leave HTC Driver Installer

Download the Android SDK: [url]http://developer.android.com/sdk/index.html?hl=sk[/url]
Unzip it somewhere
Fastboot is in xxx\sdk\platform-tools , where xxx is your android sdk folder

=== htc - unlock bootloader ===
NOTE: This will give your fastboot the **UNLOCKED ** message

Go to htcdev.com
Select Unlock BootLoader
Click "Get Started"
Select "All other supported models"
Click Begin Unlock Bootloader
Click Yes
Check the 2 boxes
Click Proceed to Unlock Instructions

Click the fastboot download
Unzip it somewhere
Open a command prompt
Change directory to where fastboot is
Run fastboot devices (it should show your device as HTblabla)
Click Proceed to Step 5

In phone settings:
Power - Fast boot: Disable

Turn the phone off
Hold Power and Volume Down
When phone comes up select Fastboot (volume up and down change selection, power

button selects it)

In command prompt:
fastboot oem get_identifier_token

Right click - Mark
Select the area as shown on the web page
Right Click inside the selection
Paste inside the box on the web page
Submit

In you email you will get:
Unlock_code.bin

Download this file and save it to the directory where fastboot.exe is.

fastboot flash unlocktoken Unlock_code.bin

FYI, To re-lock your bootloader:
fastboot oem lock

=== ready the phone ===

In phone settings:
Security - Unknown Sources: Enable
Developer Options - Stay Awake: Enable
Developer Options - USB Debugging: Enable

Download WinDroid
[url]http://xdaforums.com/showthread.php?t=2499926[/url]
Click "WinDroid Universal HTC Toolkit" under the Download heading
Either the Direct Download or the BitTorrent should give you the same file

Unzip the file somewhere

Use a USB 2 port if able
Use the original cable if able
Ensure that there is no lock screen (no passcode, no pattern, no face unlock)

Unplug and replug your phone from the computer

In a command prompt (if you loaded the android sdk):
cd \<your android sdk folder>\sdk\platform-tools
adb devices

If you don't see your phone:
Open Device Manager
Expand Portable Devices
Right Click on Evo - Update driver software
Click Browse my computer
Paste C:\Program Files (x86)\HTC\HTC Driver\Driver Files\Win7_x64

Go to where you unzipped WinDroid
Double click WinDroid Universal HTC Toolkit.exe

You may get a driver popup. You should OK the driver installation
You need to select your device.
I don't remember if there was more, so follow the apps directions.

Step 1 is already done
Click the TWRP button under "2. Flash Recovery"
NOTE: This will give your fastboot the ** TAMPERED ** message

Click "Flash SuperSU" under "3. Gain Root"
Turn the phone off
Hold Power and Volume Down
When phone comes up select Recovery
Click Install
Scroll down and click SuperSU.apk
Swipe the bottom to ok it
Click Reboot

You should now have SuperSU as an app in your list.
