Galaxy Grand 2 SM-G710 Bricked? topic

Hello all,
I foolishly wanted to install a SM-G7102 rom into my SM-G710.
I didnt backup, formatted,wiped everything with twrp.
Then Installed CM11 as instructed.
Phone got into unlimited bootloop.
Tried wipe delvik cache and wipe cache, didnt fix it.
Then i formatted everything again. And downloaded stock rom from here.
I got odin 3.09, i try to flash it but it fails :((
