4. Set the the Galaxy W I8150 into "Download Mode" -  Before connecting the device to PC USB you need to put it into download mode state, so that Odin will recognize it. To set the device into download mode, turn the 'POWER OFF' then gently press and hold the ( Volume Down, Home and Power Button ) at the same time.
Then there's confirmation message appears like the picture below,  then just press "Volume Up to continue".

If struggling into download mode, this is a little bit tricky sometime. Try to remove the battery for a while then put it back again, then try the button combination again.

5. Connect the Phone to PC or laptop - Once the device already displays "Downloading... Do Not Turn Off  Target", it's now time to connect it to PC. In Odin the COM: Mapping box will turn to color yellow and it says "added! or detected!!" in the log box when the device is properly connected and Odin recognized the phone.

(If  still struggling for the connection set up, do this: re-install driver, check and try using another good USB cable wire and PC.)

6. Click the "START" button - Once all of the above was set and went smoothly begin flashing.

Wait until the firmware installation finishes. You will be notified with a word "PASS!" in Odin if the Flashing process successfully completes. Let the phone reboot for a while, then it's time to unplug it from PC.

If the flashing fails don't panic. Switch to a different port of your PC and then repeat the process again.

Note: First boot takes longer time than usual.
