6 - Make sure re-partition is NOT SELECTED [Very important]
Notes :
- Do not disconnect the cable or turn off the device while flashing
- I am not responsible if something wrong happened to your device (use this AT YOUR OWN RISK)
- Install Samsung Mobile Driver or Samsung Kies if you don't see a sign in Odin (Step 5)
