i have a rooted evo and have flashed several roms already. My problem is every time i download a rom from xda-devlp. they download as a folder into my mac not a zip file. i place it on the root of my sd card and when i go into recovery and try to flash the rom it just opens as a folder and i cant flash the rom. ive used rom manager to flash roms before in the app it self. help is much appreciated. thanks.
