General installBash.sh white icons

hey everyone
I managed to get this script from the installous directory to work
This script installs IPA manually without installous
The app installed just fine, except for the icon. its white.
Already tried uicache, respring,notify_post("com.apple.mobile.application_installed") and other things..
the only method that work is removing the folder - /var/mobile/Library/Caches and restart (no respring!)
Another thing, the iTunesMetadata.plist is not being copy to app folder

any other method to fix the problem are welcome
thanks!
