I did it till here:

sfdisk --no-reread /dev/mmcblk0 < table

and rebooted My phone..and on rebooting now My phone does'nt display any image words nothing at all..its all white with little boxes wheres characters or numbers are supposed to be..and places where images are supposed to be is marked wid a lil x mark i.e no image..
Its gone now for sure I think..
I cant try or do sumthin..cz I probably won't be knowin which app is open or what am I typing

So Im gonna give it once again to Nokia care tomm..but could you guys tell Me what should I specifically tell em to do..so that they get it clearly

P.S My warranty also expires by 29th of this month
