你妹的，救砖回来过后web设置页面空白，应该是以前改E8C界面造成的。无法用cd等一些重要命令。
又再经历两次刷砖以后这次是终于真正的救回来了！！！！！！！！！！下图
下贴是HG8240 改配置后 TTL线下 猫的情况！！ TTL线下任何按键 命令 均无法中断启动
telnet: can't connect to remote host (127.0.0.1): Connection refused
停在这里反复连接这个地址失败一直重复
https://www.chinadsl.net/forum.ph ... d&tid=128424&extra=
经过N天坚持不解的研究，终于救回来了。救砖过程如下
可能你们打死也猜不到我是怎么中断启动的

命令用完，重启 那熟的红灯又开始闪烁了~！ 救砖成功
我就是死马当成活马医，用镊子把内存芯片弄短路（按住其中两只脚就行了，可以从TLL信息看出来短路对了没）。让系统认为芯片坏了，强制自己中断而启动华为的 U-boot 也就是hisilicon # 命令
就这么简单！ TTL不能中断的可以用我的方法，当然芯片烧坏不负责哈
