Finally bricked a phone... SG3

After years of successful rooting I think I may have killed an SG3.

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?

first of all your phone isn't dead alright there is so much hope for that device you have now.
ok boot to recovery mode and wipe cache and dalvik cache and reboot system...
If that fails,i'll advice that you use an official SG os that your phone came with and flash it with odin...
yup that should help

The device is not rooted. So flashing CWM or TWRP isn't going to work.

Here's what I did:

1. The phone is running NON-ROOTED stock 4.3 OTA from VZW.
2. Decided to root device so I tried Casual's Root app which I later realised only worked on 4.1/4.2 devices.
3. Since step 2 didn't work I tried to flash 4.1 to the phone via Odin.
4. Step 3 caused the device to no longer boot. It gives a firmware upgrade error and will only boot into download mode.
5. I obtained the 4.3 OTA and tried to flash it via Odin, no go. It didn't work.

The phone is effectively dead with only download mode working.

Thumbs up
Phone is not dead till you can get to Recovery or Download mode.
You possibly have problem of new bootloader which might not be downgradable.

My suggestion would be :
1, Flash some Custom Recovery like CWM or PhilZ through PC ODIN.
2. Enter Recovery and format System,Data, Cache and Dalvik.
3. Flash some 4.3 based Custom ROM. (download it and place it on your External SDcard before doing anything)
4. Clear Cache and Dalvik again.Reboot.

Good luck !!!

I tried to flash CWM and TWRP, both failed. However, the device rebooted and worked after flashing the failed TWRP.
