Re: UnRoot and Return to stock
Dimak:
You say this happened AFTER you flashed the stock ROM, right? So you were able to connect to Odin previously? If yes, did the flash of the stock ROM complete sucessfully? If so:
As long as you're not actually transferring data from the PC, you can disconnect even though the screen says not to. I would suggest holding down the power button until the phone shuts off, then disconnect the USB cable and see if the phone will boot normally.
Just to make sure we're not missing anything: You do have the Samsung drivers installed, right? If you connect the phone normally (not in download mode, Odin not running) does the PC recognize your phone?
If so,when you're running Odin, make sure you start Odin on the PC and enter download mode on the phone first, and then plug in the cable. If that's not it, try using a different USB port (use one on the PC, not a USB hub), and a different cable. Odin is very sensitive to connection quality.
