刷机 OpenWrt

不支持SFTP

OpenWrt 默认不支持 SFTP，请使用WINSCP的SCP模式传输文件！
OpenWrt 默认不支持 SFTP，请使用WINSCP的SCP模式传输文件！
OpenWrt 默认不支持 SFTP，请使用WINSCP的SCP模式传输文件！

breed 这个 bootloader 可以不用安装
如果后续 更换为其他固件, 建议安装 breed
否则 在OpenWrt更换其他固件 还是有点麻烦.

备份系统

可选操作， 可以跳过

可以保存在U盘中，
也可以保存在/tmp目录下, 使用WINSCP的SCP模式传输出来

无响应/忘记密码 重置

情况1:

当错误的配置了 OpenWrt 导致无法启动时, 如过跨大版本升级, 密码
当OpenWrt配置了错误的 IP 无法登录时
  1. 按住 reset 按键 直到 红灯闪烁, 等待 重启.
  2. 进入 192.168.1.1 web页即可.

情况2:

如果设置了错误的配置, 导致OS没有完整启动,用上面的办法没有时.

  1. 断电->上电

  2. 用ping工具一直ping 192.168.1.1

  3. 屏幕上会有短暂的瞬间 能够ping通

  4. 用牙签 顶一下 R3G 的reset 按钮,立即松开

  5. 用SSH 工具连接进去 ssh root@192.168.1.1

  6. 进入故障模式, 输入 恢复为出厂设置
