Default [Q] Samsung Galaxy Mega 6.3 GT-I9200 Boot Loop

Hello,

I own a Samsung Galaxy Mega 6.3 GT-i9200, I was running a unofficial cm 4.4 rom. Device is stuck in a boot loop, and can only go into download mode. I have tried everything like installing new recovery's and the stock rom for it using odin, odin says it intalled properly but whenever i go to restart the phone it doesn't change still boot loops.

Please help me out I have no clue what to do, right now i just have a 500$ paper weight.
