Default [Q] Ultimate brick

I rooted my sgs 3 mini and install custom ROMs. I loaded CM 11 (4.4.2 kitkat) from Maclaw.pl. It worked, but after few weeks, my fhone just suddenly shut down. Tried to unroot it via odin + stock ROM, but nothing happens. Or something happens, there is the samsungs own bootlogo back. But the phone is stuck on that logo. Funny part is that when I put a charger on, there appears maclaws panda charging logo. I tried to load stock charging logo via odin, but nothing happens. Phone won't get to recovery mode, but the download mode works. Any ideas what to do? Except to throw it to trash can...
