@ Ahmad: Thank you so much for the help, I turned off my device then I pressed and hold the power button and the volume down and it works! Now I can root my device
BTW, it's my first time rooting an android device.
EDIT: When I click the start button in Odin, I waited for a few minutes then it says "<ID:0/004> Can't open the serial(COM) port." I found out that the rooting failed. edited 1×, last 10.04.13 08:13:43 am
