Does it recognize it in WebOSQuickinstall? The reason I ask is because you can go through and remove all of your patches and tweaks then doctor from there. My Pre stuck on the boot logo. Battery pulls, holding the volume up, etc... nothing worked until I did this. There's a thread on it, I followed this and got my "Bricked" Pre to come back from the dead.
