The Tweak GG-4 should do the job you asked for. However, the original booting image is in /home/user/MyDocs/.N9QTweakBackup/usr/share/themes/blanco/meegotouch/images/system-services/ folder. The original images (during boot) and video are inside /home/user/MyDocs/.N9QTweakBackup/usr/share/MProgressIndicator folder.
