[EVO 4G Q&A, Help & Troubleshooting] steveno131:
Just curious on how to unroot my evo after rooting w/ unrevoked3. The S-On shows in the reboot mode, im not even sure that i downloaded the (2) required downloads. i tried to download the PC36IMG and its saying that its not valid. i have no idea what im doing, i tried to install the new update 3.7 and my phone showed the android, w/ a triangle w/ a yellow exclamation point in the center....i had to take the battery out because it just froze up. i really want this phone back to the way it was when i bought it, im not good at things like this, im desperate for some help. i just want to go to sprint and see if maybe there might be someone to help me but im afraid to go that far just yet... another thing, there is this that shows up on my sd card:
