小米路由器MINI(R1CM) can see this in web, MiWiFi 稳定版 2.22.9

开启小米路由器的SSH功能之后用户可以获得root权限

小结：

u盘先格式成fat32，里面不要放任何文件

下载开发固件升级miwifi.bin ，因为稳定版不能刷ssh固件断开小米路由器的电源，将U盘插入USB接口；

按住reset按钮之后重新接入电源，指示灯变为黄色闪烁状态即可松开reset键；

等待3-5秒后安装完成之后，小米路由器会自动重启

U盘记得及时拔出来

2，再格式化下u盘，用app连上刷了开发固件的路由器，http://d.miwifi.com/rom/ssh(或者通过http://www1.miwifi.com/miwifi_open.html的开启ssh工具)下载ssh固件miwifi_ssh.bin

断开小米路由器的电源，将U盘插入USB接口；

按住reset按钮之后重新接入电源，指示灯变为黄色闪烁状态即可松开reset键；

等待3-5秒后安装完成之后，小米路由器会自动重启

最后刷openwrtGet the latest firmware, eg:# cd /tmp; wget

Check the MTD layout:# cat /proc/mtd

If you find a line “OS1” go ahead with flashing:# mtd -r write OS1

mtd -r write /tmp/openwrt-18.06.1-ramips-mt7620-miwifi-mini-squashfs-sysupgrade.bin OS1

Unlocking OS1 ...

Writing from /tmp/openwrt-18.06.1-ramips-mt7620-miwifi-mini-squashfs-sysupgrade.bin to OS1 ...

Rebooting ...

After flashing is complete, the router willreboot. When finished you can login using telnet or web-interface on a LAN-connected client to host 192.168.1.1. User: root,no password.

SSH will be enabled after you set a password (usingpasswdor LuCI web interface), telnet will be disabled.

Please note that the OpenWrt binarydefaults to the red colorof the led instead of the orange/blue during and after finishing the boot.

如果ping 不通192.168.1.1等路由器一直红灯时再重启下即可
