I'm searching for the latest firmware for TN2464BP in CM3.1.4 and the only one I've found was for TN2464CP. It was specifically stated there that that firmware cannot be used in TN2464BP. Is the TN2464BP supported in CM3.1.4 and if it is would it be okay not to upgrade its firmware? Would a firmware in a lower CM version work under CM3.1.4?
