If you can access the download mode option, then your seemingly quite lucky for there’s a chance that you can recover it by yourself.
Hardbricks – refers to the phone as totally jammed, it doesn’t show anything, can’t access the download mode screen. The only solution for this is by called JTAG flashing, which is forcing to install the firmware back to the phone. The process is not too easy, this includes disassembling the phone, some soldering required and flashing by means of using a flashing device tool. So this method means that you cannot save your device all by yourself anymore. If you badly need to have your Galaxy S3 back to life if you can’t recover it anymore with yourself is to bring it back to your dealer.

3. Connect the phone to PC via USB. Then make sure you can see as phone “Added” in Odin log box or highlight the COM:ID once the device is detected,
4. In Odin window, DO Not tick ‘RE-Partition’ only Tick ‘Auto Reboot’ and ‘F. Reset Time’ and nothing else.
