R619AC 競斗雲 2.0 刷機教程，x-wrt系統

連接串口

路由器開機過程，串口不斷輸入 f + 回車 直到進入安全模式

 

串口波特率是115200

 

啟動到10秒左右看到如下提示按 f+enter就可以進入安全模式了

================= FAILSAFE MODE active ================
special commands:
* firstboot          reset settings to factory defaults
* mount_root     mount root-partition with config files

after mount_root:
* passwd                         change root's password
* /etc/config               directory with config files

for more help see:
http://wiki.openwrt.org/doc/howto/generic.failsafe

 

 

執行命令 掛文件系統

mount_root

 

然后執行命令 修改啟動

sed -i 's/^#ttyM/ttyM/' /etc/inittab

 

重啟

reboot

 

等待2-3分鍾重啟完成

 

回車進入控制台

 

執行兩個命令，關閉煩人的日志

 

ifconfig wifi1 down
ifconfig wifi0 down

 

電腦開啟一個簡單的http服務器，網上有很多http服務器，自己找比如  CuteHttpFileServer

把改名固件 x-wrt-nand-factory.bin 放到http服務器

 

串口下載固件，假設電腦IP是 192.168.7.100 電腦要接網線連竟斗雲lan口。

注意，wget 下載固件的地址，根據你實際情況寫，這只是給個例子參考

 

wget -O /tmp/factory.bin http://192.168.7.100:8000/x-wrt-nand-factory.bin

 

下載完成

執行命令升級刷機

 

sysupgrade -n /tmp/factory.bin

 

等待5分鍾

完成

注意，刷機用 nand-factory.bin 文件，后續升級，用 sysupgrade.bin 文件。https://dl.x-wrt.com:4443/rom//
