Root Nandroid Restore Problem

[coolguy95]

Hi,

I have recently flashed my funbook with clean ics and hadn't taken backup of my stock rom.

So i have taken nandroid backup from my brother's funbook through cwm recovery in sd card.

When i tried to restore my brother's funbook stock rom in my tab it strucks on restoring system and said "error while restoring /system"

Can anyone suggest me where i am lacking.

Thanks in Advance...
