Using Odin to flash a custom rom Nearly bricked my Samsung Epic Touch 4G. Managed to boot into Odin Mode with a USB jig. I'm back where I started now and need to re-evaluate what to do next.

The phone is rooted, won't see the SD Card or Internal anything. My only option is using Odin to get a custom ROM back on there. Can someone point me to a step by step? My last attempt at this led me to having to work with the USB jig to get another crack at it.

Thanks!
You'll want to Odin a stock (or nearly stock) ROM after a softbrick.  This guide on XDA looks pretty good and includes a pre-rooted but largely stock ROM that should work for you.  If step 4 fails, disconnect and reconnect your phone to the PC; if it still fails, reboot the phone and try again.
