Note 2 seems bricked after trying to go back to stock firmware. Help needed!

Hi all,

I was using my Galaxy Note 2 with the latest Resurrection Remix ROM, but wanted to revert back to the stock firmware .
I downloaded the latest stock firmware and tried to flash it directly with ODIN.
Unfortunately, the process stopped at about 3/4 of the progress bar. I tried several time, changing USB ports and slots; even computer. After one try, the messages changed and the process stopped event before trying to write with the message : "There is no PIT partition".
The download mode shows the usual warning and download screen. But if I try to go in recovery mode or just boot normally, I get the "Firmware upgrade encountered an issue...".

What I've tried so far:
. Flashing several stock firmwares via several version of ODIN.
. Kies upgrades (tried about everything there).

I also tried a PIT file, but got the message: "Re-Partition operation failed".

I really don't know what to try anymore :(
Any help would be greatly appreciated!!!


(edit -> oh, and I've also tried with firewall and antivirus out)
