I tried to root my evo phone. I followed some instructions having me DL pc36img.zip and type some commmands in cmd window. But after the process was done the phne was unrooted and in ver 2.1. So i have a buddy pretty good with these things so he sent me a rom to flash it back to 2.2. Now the phone stays between the sprint screen and 4g screen on bootup. Can anyone pls help.
