Accidentally hit PIT during Odin update now phone is stuck I was attempting to flash a handset using Odin, and accidentally clicked on the button marked PIT, and now the Odin is saying similar to this message - 'connecting phone ------ pc'. 

Also, the handset cannot be rebooted nor put into downloading mode. 

Please advise?
Well, you seem to have 2 options:


If under warranty, send it to service center, your Main board (PBA) should be replaced.
You probably will need a JTag repair!


AFAIK, there is nothing you can do at the moment, by yourself to get the phone working, apart from the options mentioned above!
