Need to Find updates for rooted phone with unlocked bootloader

[Guest JonN1]

I have a rooted Nexus One with an unlocked bootloader and I am trapped with the ERD79 build after re flashing the phone. All the updates I've downloaded and tried to run off the SDCard with the name "update.zip" are giving me the error "Verification Failed"...

According to this post: http://androidforums.com/nexus-tips-tricks...ota-update.html

There is a special file I need to use since my boot loader is unlocked located at this website (modaco): http://android.modaco.com/content/google-n...optional-himem/

I can't find this file... Is there someplace to get updates for an N1 with an unlocked bootloader? Can anyone help me???
