Hello how are u all
The problem started as both packages the mmmrpc and starhash enabler got locked and can't be installed , although i deleted both packages but they kept returning which prevented me from installing any new app for my Nokia n900 , then i have done stupid thing which is deleting the dpkg file in usr/bin directory and dpkg doesn't exist anymore which means that i can't install anything .. i checked the file with cuteexplorer and i could find the 3 dpkg files but in the terminal it doesn't exist .. please help i don't want to flash my Nokia
