I am putting it here because I was on CM7. I'm not sure which nightly, but it was pretty recent.
I was in ROM manager and selected the latest Liquid ROM (3.07).
clear Delv cache....go.
The install seemed to go fine but when the phone booted I got the Motorola symbol....never went any further...I waited 10 minutes.
I went into recovery (X-power) and I got the dreaded triangle of death.
I've pulled and restarted several times....nothing is working.
