how to flash t889 into DN4 topic

so i was trying to mess around a lil bit and i flashed DN4 for the N7100 . Amazingly , everything worked perfectly except the baseband was unknown. I flashed a modem but it still didnt work. Apart from that, everything works great including the wifi too. Anyone with a workaround for the baseband fix could kindly help..... I am using dn3 which great but it so lagging and something it wont wake at all I have to took the battery out and install . I hope you guys have some idea
