Updated my phone and it seems like it soft-bricked during the update. I've tried deleting the cache, factory reset, and flashing a stock ROM with Odin. Whenever I try to flash a stock ROM it fails on my computer screen. Searched around on other websites and can't find a solution. :/

Phone goes directly into Odin Mode with a "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again. Tried downloading Keis older and newer version and it won't recognize my SGS3. Not sure what else to do. No insurance.
