Connector installation is a reliable process, so if it is not successful the phone is rejecting the installation. In this case, there is probably not enough of RAM memory, storage memory or there is something wrong with the phone. Try deleting a few apps and restarting the phone.

If it is still not possible, then the phone is not standard Android and is not compatible. Send us more details about the specifics of the phone so that we can either add support for the device or assist in achieving a successful connection.
