V7 AP无AC配合情况下手动降级V5版本操作经验案例问题现象：

部分局点存在如下情况，手头的AP为V7版本，现在临时需要降级V5，按照常规操作AP V7版本降级V5版本，需要在V5版本的AC配置下就行操作，但是手头没有V5版本的AC，手动操作AP直接降级。

需要提前准备AP V5版本的软件

第一步：进入V7boot Ctrl+F

第二步：进入V7boot 通过网卡口，传入V5 AP bin文件，提示更新boot版本的时候选择Y

第三步：再次Crtl+F格式化AP flash

第四步：导入V5 AP版本（从AC V5版本中获取，建议使用最新版本）

第五步：重启，降级完成

第一步：进入V7boot Ctrl+F
