I believe it`s because the firmware you downloaded is not compatible... Try a different firmware, I mean BOTH the MAIN and FS.
EDIT
No sorry. You miss read the turorial.
There must not be 2 FS. PAY
ATTENTION : You first add the MAIN part and afterwards the FS part of the firmware. NOT 2 FS, only one. AND I DON`T GET IT: you try to debrand it by rebranding it with Vodafone firmware again ? LOL : Definetly use a different firmware.
