For those who need help:
1. Turn your phone off
2. While holding volume down, press power
3. At the prompt, choose bootloader
4. At the next prompt, choose recovery
5. You will get to a black screen with a phone and triangle
6. Press power and volume up at the same time (I had to wait several minutes for this to work. Your experience may vary.)
7. Some blue writing will appear at the top of the screen. Select "Apply update. zip" (I renamed mine update.zip) BE SURE THAT you don't rename your file .zip.zip You should check the file name in your SD folder from your Evo, not your PC.
8. Yellow typed info will scroll on the screen. Once the update has finished it will tell you, "Reboot to finish installation."
9. Select the proper instructions for the reboot and use the power key to enter, as instructed. A weird phone with an arrow will show up and turn on and off a few times. WAIT for this to finish.
Your Evo will reboot and that's IT!!
*This is assuming you already copied it to your SD card
