i uninstalled google maps with root explorer, to update the app to the latest version. when i did this, the app was fully removed from the phone, but now i cannot reinstall the updated .apk file. when i click to install, the installation completes to say the app was not installed successfully. how can i reinstall the maps app, it took me awhile to get the gps fix working properly. *i recently flashed the phone to unlock it.
