Great job Kevin, now all you have to do is accept your answer so we all know that your case is closed.
What is a 'Dig' ?
@Michel, probably abbreviation for digitizer...

This is to help others with the problem:
Take the OEM part that you didnt replace, like the LCD and pop it onto the phone without the digitizer. One by one try parts like this. I have noticed that many aftermarket parts can cause endless boot issues. once the phone boots up, try installing the other part, and you will notice it sometimes freezes up. Quality control in China sucks, I can't tell you how many times I've had to troubleshoot like this.

Do you get an error when restoring via itunes?
Possibly use irecovery to change the env to auto-boot true?

did you try to restore via itunes.
i think is software problem.. just try first the basic troubleshooting... software first...
question.- what did you do last time before its happen?
Was this answer helpful?
For me it was connector #3 that did it. disconnecting that cable lets me boot properly now.

That means your #3 ribbon is damaged and causing a short and thus the loop. Replace that ribbon and see if that helps.
