Instructions:
1. Create your background image size of 480x854 in PNG format
2. Rename it to meegotouch-desktop-bg.png
3. Copy the resulting file to your smartphone in the Downloads folder
4. In the same folder Downloads unzip libmeegotouchviews-modified-default.css from the archive (http://www.mediafire.com/?b05rri3b3x20ris).
5. Open a terminal and type:

Code:

devel-su
rootme (the default password)
cp -f /home/user/MyDocs/Downloads/meegotouch-desktop-bg.png /usr/share/themes/blanco/meegotouch/images/backgrounds/
cp -f /home/user/MyDocs/Downloads/libmeegotouchviews-modified-default.css /usr/share/themes/base/meegotouch/libmeegotouchhome/style/

6. Reboot

PS. For the subsequent change of the background, you need only change meegotouch-desktop-bg.png
But to return to the standard change libmeegotouchviews-modified-default.css to the original (http://www.mediafire.com/?yexu8a70ld534iu).
