Try a different kernel, that message appears when you flash the wrong kernel....good luck!

If you were on MDL, you need to use Loki. Try a different kernel too and if not you probably need a different firmware.

A while back I had something similar happen to myself as well. The only way I was able to revive my phone was by performing an emergency firmware upgrade via Kies. This will bring you back to your original stock firmware so you will have to re-root your phone.
Hope this helps

If you were on MDL and installed a new bootloader, then say goodbye to custom ROMs like CyanoGen Mod and AOSP.
