linksys E3000变砖


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

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
