1. Connect phone to pc via usb
2. Open Odin
3. Put phone into download mode (turn phone on holding volume down, home and power) and hit continue
4. Odin should show that the phone is connected [COM]
5.In the Options section, make sure that only the Auto Reboot and F. Reset Time boxes are checked and everything else is unchecked
6. Hit the AP or PDA button (depends on Odin ver) and select your stock rom (.tar, .tar.md5)
7. Hit start and wait.
Makes alot sense, thanks i'll do it later and update you if it worked

You should download Samsung drivers for your PC before using Odin. I think that was required for S7s, dunno about other samsung phones.
Thanks i'll try it later since i can't atm
