linksys E3000变砖

leno***

linksys E3000变砖：
1、机子开机后不能ping通，返回为时间超时；
2、电源灯闪烁，一直这样循环；
3、reset键不起作用，30/30/30也没有用，
4、usb转tt可以进入CFE 。
请高手指点，究竟是什么问题？

如果没有刷机，那就是cpu虚焊了。bcm4708机器的通病。

TTL中断，然后进刷机模式上tftp刷固件，Ok

有ttl 还砖什么， 吞吐量中断一下，电脑手动IP到192.168.1.100 ，然后浏览器就可以打开路由升级界面了

可以进入CFE

可以进cfe 就可以刷机，电脑设置固定IP 与路由同网段就行（比如192.168.1.100） 就能连接
进入cfe模式后 进入浏览器输入192.168.1.1 就能出现刷机界面了

能进cfe 你把cfe进去之后的启动记录 发出来看看

看红字，你的eth0 找不到，就是没有了wan口，现在不知道是物理的坏了还是nvram遭到破坏

你看机的时候接通ttl 在ttl 下一只按 contr +C 进入中断，出现cfe》 之后，输入help 或 ？ 看看命令列表，清空一下nvram 试试
如果可以看看能不能重新设置eth0 的mac 和ip 地址为192.168.1.1
你可以发看到的内容发出来再看看怎么设置
