FYI, rajendra82 has produced stock 1.3 versions of the the files in the OP. I've personally tested the keepCWM version, but there have been no reports yet on the full restore. Let us know here and in the original thread whether they work for you.

If I get a chance to test the full-restore down the road, I'll edit this post, but it would require considerable juggling of SD images on my part.
