Compile TL-MR6400 v3 APAC

Hi friend .... I managed to compile the firmware for my MR6400 v3 ... This is the APAC version ...
everything is as expected .. including the modem can connect to the internet .. but I can not turn on the LED modem signal, still looking around inside the forum ... I just doubt the systemlog .. there may be an error ..

Here is the log:
