I'm in Istanbul, Turkey. I will go to the support center now and I will let you know what is their procedure.
Thank you again.
after support center edit: They took the phone without any complain, I took the risk and told them it's unrooted, they didn't ask it though. They replaced the motherboard, flashed the 4.3 stock and gave the device back to me in 4 hours.
Samsung surprised me today.
Thank you all dear xda family.
