请问我是不是有几个固件在设备上，我用
CFE>nvram erase 命令后，还是这样子，出现上面的情况，请问是不是没有清出nvram 成功？我该怎么操作？ 我是按dd-wrt wiki上的说明做的 http://www.dd-wrt.com/wiki/index.php/Serial_Recovery 我的开机时的ttl相关信息为

然后就停在那儿不动，能看出是什么问题不？ 问题和我遇到的一样，没有拿到CFE的提示符。

这是刷错了固件造成的，如果没有刷CFE（用JTAG或仿真器），用TFTP应该可以救回，先找到原厂固件或ldd-wrt.v24-14144_NEWD-2_K2.6_big.bin刷回。前期应该先恢复出厂设置（按WPS键也行，断电再通电10S以上），再次断电再通电，同时开启CMD，PING 192.168.1.1 -T 直到ping 通时，点TFTP上传！
如果刷错了CFE,只能用JTAG或仿真器重刷原厂的CFE.
