I am trying to flash the KCS_A8V3_V3.15.0.bin firmware to my Kincony KC868-A8-V1.5 board. It flash but does not boot up. What did I do wrong? I flashed with KCS_KC868_A8_V2.2.14.bin it works but limited features. 
Can this board flash with the latest KCS_A8V3_V3.15.0.bin firmware?
Does this board compatible?  The board power light up but the Wired Internet RJ-45 no lights up.  AP no available too.
