And it worked...
I flashed my N8 and again tried the same patch.. and guess what this time without any problm it worked.
Thanks guys...
However, i noticed very little bit of change in bass.. It cud be becoz earphone itself doesnt support loud bass itself.
Also, I would like to mention the mistake that i think i wud have made last time while patching and that caused my n8 dead..
I copied content of private folder in c:/ instead of coping private folder itself into c:/..
So, to others who are also facing this prob. pay attention while copying private folder into c:/
