So I was gonna use ROM manager for the first time to install CM6 and after selecting my ROM it says "will reboot into clockwork recovery and install rom". But when it reboots it came to a screen showing a triangle with an exclamation point and a little green android robot next to it. Been like that for 5 minutes. Is it doing something? I'm afraid to reboot lest I brick it. Some help is appreciated. Edit: I figured out it went to that screen since ROM manager failed at installing the file. When I hit power, it brought me to clockworkmod recovery. I had to manually select the file using clockwork.
