Unhappy [Q] Got stuck trying to update to kitkat

Hi,
I need help because after 20 hours of trying i gave up.
I've tried like 8 guides of how to update the rom and it always failed.
I tried 10+ rom versions and put them on sd card and it fails with "status 7" or just "aborted" with no reason.
i'm using cwm 6.0.3.0, and when i try to update it using odin it also fail.
also when i try to load the original stock rom for my country it fails with no reason just "aborted".
I also tried fastboot in download mode but it wont recognize my device even with correct drivers.
now the worst problem is that when i restore it to the previews backup it works but the device is unusable, stuck after one minute.
I'm really frustrated and i hop to get some help here.


Thanks
