i rooted my evo 3d. downloaded the 2 zip files. got into bootloader, and when i try to run recovery, as it said in the walkthrough, it shows the black screen with green refresh arrows, then changes to the red exclaimation mark. when i select bootloader, it says "no image all the way down the screen, prior to not working. what am i doing wrong? i really want this rom on my phone, but i brand new to this, and i have no idea where to go from here. please help. thanks
