I have maybe destroyed my s3 i9300 after wrong flash. All what I see now after power on is (picture1) and canīt go to recovery mode. I can go in download mode (picture2 and 3) but if I can flash via odin stock firmware now, that stop on "setup connection" and nothing more. I canīt see on xda or on google how I can try unbrick my phone via Multiple Firmware with PIT file if is possible. But I mean is mainboard death.
Thanks for help
