This chipset R8j32740fp42 is renesas RX24T family it needs debbuger for connecting to PC there is whole evaluation studio for it as there might be out_tro command. It possibly can be unlocked as there is access to whole memory even protected areas, however costs are ~300$ per unit plus you have to resolder ~100pin chip from evaluation module to drive PCB possibly multiple times so clip would be recommended. Faster and cheaper is to get LG drive.
