What boot.img ?! ...I didnt see boot.img attached to the post and I use neXusRecovery as you wrote in the requirment...but from where I can get boot.img ? Is it from here : http://xdaforums.com/showpost.php?p=40187247&postcount=37
There is a boot img and a recovery in op. Under the rom download link.
If you flashed another kernel after you updated to JB you need to flash the one in the OP from fastboot.
If you want full stock you can flash the stock recovery also.
