wa2620i-agn导入官网下载的升级文件升级不了

wa2620i-agn在http://www.h3c.com/cn/Service/Document_Software/Software_Download/IP_Wlan/AP/WA2610E-AGN_WA2620E-AGN_WA2610E-GNP_WA2610X-GNP_WB/下载升级文件，上传bin文件后提示Something wrong with the file.

官网提供的三个版本都试过，结果都提示错误。

在BootWare主菜单下进入文件控制子菜单，并查看文件，系统显示如下：

===============================<File CONTROL>===============================
