If you can get to download mode, check out Lumin30's guide for Heimdall...works like a charm.
Once you get back to GB, you can also use Heimdall to flash AntonX's Basic-With-A-Twist kernel. That will get you rooted. The rest is up to you.
Actually, all the OneClicks were failing on FACTORYFS.RFS... that was part of the problem....
But that link lead me down a path to other links, and this one actually brought the phone back to life!
