auth fail after updating

Gordan

Hello there ..
I had tried so many of CV338H-A42 software but it's not working and when reading the printing information it says AUTH Fail ..
anyone has an idea ??

is this about mac address but I don't see a connection between updating  with RT809H and MAC address it must be something reasonable !!!!!!

我也碰到了这样的问题，指示灯绿灯，开不了机，打印消息显示：AUTH_FAIL，换了EMMC也不行。原来拆下来的EMMC经检测也是正常的。不知道这样的问题是什么原因造成的。
