You can access the download mode on the device. You should try to flash stock rom again with an older version of Odin. That might solve the problem.

I tried it already bro. but it completes the download process on the phone via odin 5.0 and 4.4.2 but it stucks on the download screen. didn't boot. it is 6.0 now but while am trying to downgrade it. it stucks.

You cannot downgrade from 6.01 to 4.4.2 as it involves a bootloader downgrade which hangs your phone . Flash the latest firmware via odin 3.10 is good . Also check your data cable for good connection else flash with a different data cable .
