Ahhhh found a way to restore!
Yeeeeeeeeeeeeeeeeeeeey!

First, look at this post about a prog http://forum.meego.com/showpost.php?...0&postcount=50 It have this background change as option.

As last resort i'we downloaded clean backup, put zip into my phone, unziped and made full restore in that prog. Worked sweet!

Besides, i'we compared my backup and that one fith full folder-text compare. While textually files are identical, files have different bytesize, and different below HEX ehamination. Seems that some wierd encoding or tabulation bug.
