求教杂牌BCM 4708路由器 救砖 ,求深圳南山福田有焊工好的朋友帮忙。
网上买了一个BCM 4708 的AC路由器,刷固件是刷成砖了。情况如下:
正常刷机方法:
1.按厂家的说法CFE的IP是:192.168.8.1。但在路由好的时候:192.168.1.1也能进CFE MINIWEB。
2.先路由器断电,电脑网卡设置成192.168.8.x(不设置默认网关和设置默认网关都试过),然后电脑ping192.168.8.1 -t,路由器按住reset键再上电,按住一会松开,tftp才能ping通,等ttl变成100时浏览器打开192.168.8.1上传固件刷机
3.TFTP勾选自动刷,捅reset,上电,等几秒,松开reset,就会自动开始了.
成假砖后得情况:
CFE下:
以下操作两个IP都试过了。并在不同电脑的WIN7下尝试过,win10也试过。
按正常刷机方法操作,机器亮灯情况正常(按住reset键上电——开机全亮——只亮LAN口和电源灯——松开RESET键——灯全亮——一次只亮LAN口和电源灯),但是PING不通cfe的IP地址(8.1和1.1都试过)。CFE的miniweb也进不了,用软件全自动刷机也不成功。
TTL下:
机器自带TTL针,不纯在我焊接不好的原因。
笔记本没串口,用的PL2303转接。TLL波特率设置的是115200,路由器的字符能正常显示。但命令能不能发送到路由器不确定。另外我有两套同样的PL2303板,以下操作两套都试过了。并在不同电脑的WIN7下尝试过,win10也试过。
TLL接法是TX-RX RX-TX GND-GND。这机器特殊接上GND后灯全亮,不能正常开机。所以要等机器第一次灯全亮后才能插上GND。另外反接TX和rx我也试过。
按特殊方法开机后,TTL输出以下字符:期间按CRRL+C中断无效。其实可以看到加载路由器固件了,但是就是不能中断启动。
分析
个人感觉和群里的人分析,CFE没挂!但是怎么就PING 不通!TTL不能中断。
根据TTL输出,可以发现是分区错误。
另求深圳南山福田有焊工好的朋友帮忙。当然有编程器更好了,可以付费。编程器需要的固件已准备好。
能接通TTL就出现下面的提示:中间那个QQ联系不上。

先找编程器固件,在弄个编程器慢慢刷
操作系统问题?用winxp试试。
usb转ttl问题?在其他有ttl的路由试试或整个usb编程器。
还是找个XP试试吧
学习帮顶顶了!
买个编程器自己刷,不贵
