See if the full FXZ works for you.
Use RSD Lite to flash it. If that works, let me know. That will wipe the contents of your phone including your sdcard so make sure it's all backed up properly first. If that works, let me know as I'll have to look into what's going on.
Hot damn Samuri you're the bomb! I was experiencing exactly the same thing and had tried all the same options Daemoen tried (many, many, times) without luck. I tried this method (download the zip & run RSD Lite) and my Bionic is no longer a brick. Thank you!!!
