I was running OTA 4.3 from vzw and wanted to root it. I ha used Casual in the past I tried it again and it failed. I noted it was for 4.1/4.2 so I tried to Odin back to 4.1 from OTA 4.3 Little did I know this was bad juju. Now I have a phone that won't boot, it keeps saying firmware upgrade an issue. I can get to download mode but have no idea what to try and flash to it since I've read that flashing anything less than 4.3 won't work and the 4.3 official isn't available.
So, is it dead?
