Step 1:: Go to settings > General> About Phone > Software Info. Scroll down and you should see "Build Number" Keep touching this until you enable (Developer options). Phone will actually warn you and start count down letting you know.

Step 2:: Go back to regular "General" tab under general. You should now see a select icon that says "Developer Options". Open it up.

Step 3:: Select the options "Enable OEM Unlock", and scroll down until you see "USB Debugging", enable that one as well and then get out of developer options.

step 4:: Now you need to download "adb and fastboot" to your computer. You can find the program through XDA using a google search. This is basically a program that will open up a command line once your phone is plugged into the computer (Think MS DOS, or Linux). This may seem scary, but dont panic, typing a few words in it isnt going to kill you, or destroy your phone (depending on what you type).

***Side Note. Remember the OEM Unlock? Now what we need to do is to actually unlock the boot loader. Let me explain based off my extensive knowledge and certified degree I obtained at 20 Min Google Search University! My elementry (think grade 3) understanding of the bootloader for our phones is that its basically a stuck up jerk who starts issuing commands to various processes on our phone in order for it to work.....how it works upon start up. He makes sure everything does what its supposed to do in order for our devices to work correctly (Or at least as Google and Metro PCS intended them to work). We want him to loosen up and we will do that by unlocking him.

Once you download and extract the downloaded ADB and fastboot program onto your PC, you need to actually locate the folder. Go to My Computer and head to the program files in your C drive.

Fish out where it is exactly! Once you find it, move it to your desktop for easy access. Open up the file, and start the program once you connect your phone to the PC. IMPORTANT Once your phone is connected to your computer, and "adb and bootloader" is running on your computer.....the folder is an actual living breathing organism that allows you to transfer files into your phone issuing commands! Example:: You can move the modified file our friend posted to root our phones into the folder then issue commands to transfer that data into our cell phone!

**USB Debugging Unlock that we did earlier is essentially what enables developers to issue commands, clean up, or repair phones through a USB Cord. Once you start this program your phone will confirm that you want to use this feature and enable it.

Step 5:: Now that we are plugged in and that "ADB and Fastbooot" is running and ready to go we can unlock the Bootloader. To do this, once you start adb and fastboot and the console is up and running waiting for your commands type.

adb reboot bootloader

*Your phone should start doing some creepy stuff. It will essentially turn black with a TINY display in the top left. If you have made it this far I salute you.

now type

fastboot oem unlock

*This should unlock the bootloader! Congrats if you did it correctly.

now type

fastboot reboot

and it should reset your phone (as in factory reset). Now you need to plug in your phone again, open up adb and fastboot again on your computer. (Remember the adb and fastboot file we moved to our desktop? Now we need to follow the instructions posted earlier and download the file he posted and go from there).

***Note, the adb and fastboot folder in our desktop now is actually a working file that we can utilize to transfer files into our phone using the console! Move the file Brad created into that folder, THEN issue the commands he posted so that it transfers to your phone.

I just want to say I realize that there are a ton of unanswered things folks may have with the BRIEF description I posted. I looked into this for a full day or two to get a basic understanding of all this.....then took a leap of faith and downloaded a random file off a hacking website from an anonymous creeper in hopes it would actually root my phone. It did. DO YOUR HOMEWORK! Look at some videos on youtube, post questions, and see what you can understand.
