Now in SEtool2 Lite, make sure W660 is selected as Phone type, uncheck 'Bypass DB2020 security', and check 'Use "quick access" patch', (if it hasn't already) remove the MAIN from the files box, and in the MISC files box, browse to the Add video to Walkman 2.0 you just extracted.
Your SEtool Lite window should look a bit like this:
How to add video at walkman2.0
Take care NOT to press WRITE GDFS as that will damage your phone!
It will now patch your phone, now a lot quicker because you just applied the quick access patch.
Once SEtool2 Lite has finished (when it says "Elapsed: xx secs.") disconnect your phone, remove the battery then reinsert, then turn it on.
Now your video files was added to walkman2.0.. Enjoy!!
