So I rooted my phone, then unrooted it, to see I had no service.

So I was using Odin to restore to stock 2.3.5, but I had to unplug the usb and plug it into another port, while it was in download mode.

Now it is stuck on the connect phone to PC screen. I don't know what to do now. I think it is bricked or soft bricked. Help?
As long as data wasn't transferring to the phone when you did that, a simple battery pull and replace + a reboot should fix your issue.

I'm also going to move this to the root forum since you're trying to unroot.
