I bought some 5Ghz dongle to connect with LP v1. It will work??

I use lattepanda V1 4Gb/64Gb S70CR700. So I think "Lattepanda V1.2 for CR700 z8350" BIOS is right one. But when I flashing BIOS to lattepanda, red led still blink. What can I do?

I can't boot 5V3A adapter. and lattepanda v1 is not using RTC battery. Also I removed all the peripherals, but It's still not booting

I use 5V 3A adapter too and V1 model is not use RTC battery. Also I removed all peripherals and tried to boot, but nothing happen.
