Artist background images are not showing up

Hi all,

Am facing a problem.
My phone is Samsung Ativ S and its still under GDR2.

I had consumed hell lots of time to set artist backgrounds for my songs ( For Indian songs, not an easy task to set artist background).

My mobile's CSC is XME. Tried changing to others to check if GDR3 is available. Already I had updated artist background images for all of my songs using MPAtool. Before I changed my CSC, I copied the music folder (including the hidden folders) as it is from my phone to my laptop. After my phone restarted under new CSC, I saw my music data gone from my phone. So I pasted the copied data from Laptop back to Phone and surprisingly there are no artist backgrounds which I had set earlier.

Really I cant take the pain to get the artist background again for all songs. :sweaty::sweaty::crying::crying:

Generally if I change a windows phone (for ex: from ATIV S to Lumia 930), do I need to set artist background again in new phone. :unhappy::unhappy:

Did I missed something while taking backup? or copying complete music folders?
How can I restore back my artist backgrounds? Please suggest.

Thanks,
Pavan
