There is one way to restore the sounds but not the CP by program the eeprom AT64A on the Head Unit with the old (original HU) image. The way to do this is using a <a href=\"https:\/\/amzn.to\/2K2k6Y2\" target=\"_blank\" rel=\"noopener noreferrer\">CH341A USB programmer<\/a> with some 30 agw wires, small enough to slide through the vias on the PCB. If you received a Head Unit that has CP removed, you may need to use VCDS to turn on the Suspension and other menus, especially the BT module (the telephone option must be set to UHV\/BTA). If you upgraded the MMI software and bricked the HU, you may corrupted the 2 EEPROMs on the board which not much you can do besides getting a new one.<\/em><\/p>\n<p><em>We can also remove the CP completely by sending the CP image of the new HU to <a href=\"https:\/\/www.digital-kaos.co.uk\/forums\/showthread.php\/454951-Audi-MMI-2G-component-security\/page19?highlight=MMI+component+security\" target=\"_blank\" rel=\"noopener noreferrer\"><button class=\"w3-button w3-green w3-round-xlarge\">this website<\/button><\/a> for CP removed image on your HU.
