Done that several times already, did it one more time right now and nothing happens. The link you gave me says at the end:
"If your device is stuck in bootloop (device restart continuously after showing Samsung logo ) then restart your device in downloading mode, open Odin, click PDA button and browse param_I8190.tar then click on Start."
But the file I downloaded with the firmware is just one, there is no param_i8190.tar.
