set wallpaper in K770i

I change the default wallpaper in my 770i to "Blue Orbit". After restarting my cell, I get the theme related wallpaper and not Blue Orbit.

Tried 'master reset', tried flashing with the official Updater from SE.

It has been suggested that the provider may block updates - is this true? Will generic flash software (that is: provider independent) solve this?

Don't want to screw up things just to find out it doesn't work

Thanx

Never heard of this problem before...

Just dont restart it or try unlocking it, not sure if it will work but it might, maybe someone else would know.

Just a suggestion.
