This is an intro to rooting your Sprint Evo 4G or ANY Android device for that matter. I want everyone knows what root is and why you might need it. Whether you have a G1, Mytouch 3G, Slide, or Nexus One then you've probably heard about rooting or jailbreaking your phone and I just want to make sure you know what it all means. As a result, hopefully there will be a few more educated users out there.
HTC EVO simple root for Windows users
Warning: Hack at your own risk. Watch the videos below if this is your first attempt. Before you start, backup all the files from your SD card and delete/format your SD card.
First you need to download and install Microsoft .NET Framework on your PC: http://download.microsoft.com/download/1/B/E/1BE39E79-7E39-46A3-96FF-047F95396215/dotNetFx40_Full_setup.exe
Then install HTC Sync on your PC:http://member.america.htc.com/download/Driver/HTC%20EVO%20(Sprint)/HTC_Sync_2.0.40.exe
Then download the OTA Simple Root.zip and unzip: http://myevo4g.net/simple/?file_id=1
Open the OTA Simple Root folder and once inside, open the OTA Simple Root application program then click the buttons starting from Step 1-4 and FOLLOW THE ONSCREEN DIRECTIONS. If at anytime something goes wrong in any of the steps, don't panic. Just delete/format your SD car and start over from Step 1.
After you're done with Step 4, open the menu and click "Extras" then "Flash Recovery". Then select the Recovery of your choice.
After you've completed all the steps and have loaded a custom ROM, remove all of the files no longer needed on your sd card by clicking "Extras" then "Clean Root-Files." If that doesn't work, delete all the files manually (including PC36IMG file).
To boot into Recovery on your own, power down your phone then press and hold the power and volume down buttons until you get to the screen with the skating Androids.
Once you're in Hboot, wait for a second (its gonna scan for the PC36IMG file again so hopefully you deleted it) then use the Volume buttons on your phone to select RECOVERY and use the power button to select it.
You should now be in the custom recovery and from here you can wipe, wipe cache, wipe dalvik cache, and flash any custom ROM of your choosing.
