Samsung Galaxy S3 (i9300): Wiped Download mode Something went badly wrong while trying to flash my phone. I have somehow managed to delete Odin/Download mode. I CAN access ClockworkMod, but it's a very old version not supported by the ROM I wanted to use. I cannot access download mode.

Is there any way I can update ClockworkMod and/or restore Odin?

I appear to now have some kind of download mode, though it's not the Samsung one - I just flashed a new ROM. Going to close this either way, as I don't think there's a simple solution other than sending it back.
