With the release of the Flash Patch v1 tool (http://forum.xda-developers.com/showthread.php?t=814461) I tried to download the Nexus One Cyanogenmod latest nightly, I tried to flash it and it gave me an error...
I tried both evo and nexus roms. Failed with an error 7 during install.Same here...I only tried AOSP for the Nexus One though, I haven't tried an EVO ROM yet. Have you tried both? Did both fail?
