有一台蒲公英工业4G无线路由器，今早登录管理界面的时候，遇到了一个报错

/usr/lib/lua/luci/dispatcher.lua:206: /etc/config/luci seems to be corrupt, unable to find section 'main'
stack traceback:
    [C]: in function 'assert'
    /usr/lib/lua/luci/dispatcher.lua:206: in function 'dispatch'
    /usr/lib/lua/luci/dispatcher.lua:175: in function </usr/lib/lua/luci/dispatcher.lua:174>

查看指示灯显示sys 红色。
