Revert from MIUI to Motoblur

I am a proud owner of Motorola Defy. A few months ago I upgraded my defy from 2.1 to 2.2. Although it had new features it became a bit laggy and so finally I decided to root my defy and install MIUI Gingerbread. I was using MIUI Gingerbread all this time and suddenly it started itching me and a thought came to my mind that I want to experience Motoblur again. I had already created an image of my Motoblur Froyo before installing MIUI Gingerbread. So I went ahead and reverted the Froyo image back on my defy. But then some of the things stopped working: e.g. Camera is not working now. I found that the Foryo image did not copy the Motoblur Froyo Kernel and when I reverted back my defy is still having the MIUI kernel. Can someone help me getting back to Motoblur Froyo or can I download the original kernel and re-install it back to my defy? Anything would help.... Thanks.
