I used oneclick unbrick a few times ( Thank's to Adam Outler & Benjamin Dobell) as my phone soft bricked as i was flashing it.
there's a known issue (a clash between) the oneclick zadig drivers and the samsung phone drivers.
basically when you use onclick unbrick odin can't find the phone, you have to restart the pc and or reinstall the samsung phone drivers because odin dosen't find the phone after unbricking.
Ive found a work around for that.
(I'm Running Windows 7)
Once you have used oneclick unbrick, go to your control panel, then device manager.
Once in device manager scroll down to Universal Serial Bus Controllers.
Look for NEC PCI to USB Enhanced Host Controller (B1)
Uninstall it, then click actions at the top of the device manager box.
Now click scan for hardware changes, this should reinstall all the drivers back in again, and the phone should be found in Odin without restarting or reinstalling any drivers.
This method uninstalled a few other things (i tether my phone) but all the drivers reinstalled again and there was no other issues once i had clicked scan for hardware changes.
Saved me a lot of trouble shutting down and restarting and reinstalling drivers etc
Have a try and tell me if it works for you too
