小米路由器R3刷机教程

全套刷机工具和固件

一、升级到miwifi_r3_all_55ac7_2.11.20.bin固件

二、开启ssh

http://192.168.31.1/cgi-bin/luci/;stok=cbbff01508d95c563042c23c659c8cc3/api/xqnetwork/set_wifi_ap?ssid=tianbao&encryption=NONE&enctype=NONE&channel=1%3Bnvram%20set%20ssh%5Fen%3D1%3B%20nvram%20commit

http://192.168.31.1/cgi-bin/luci/;stok=cbbff01508d95c563042c23c659c8cc3/api/xqnetwork/set_wifi_ap?ssid=tianbao&encryption=NONE&enctype=NONE&channel=1%3Bsed%20%2Di%20%22%3Ax%3AN%3As%2Fif%20%5C%5B%2E%2A%5C%3B%20then%5Cn%2E%2Areturn%200%5Cn%2E%2Afi%2F%23tb%2F%3Bb%20x%22%20%2Fetc%2Finit.d%2Fdropbear

http://192.168.31.1/cgi-bin/luci/;stok=cbbff01508d95c563042c23c659c8cc3换成你自己的，一行一个复制到浏览器回车

三、刷入u-boot和padavan固件

使用winscp上传u-boot和MI-3_3.4.3.9-099.trx到路由器tmp目录，登录协议选scp
然后在putty中执行以下命令(逐条执行)

nvram set boot_wait=on
nvram set uart_en=1
nvram commit
mtd write /tmp/uboot.bin Bootloader

cd /tmp
dd if=MI-3_3.4.3.9-099.trx bs=4194304 count=1 2> /dev/null | dd of=MI-3_3.4.3.9-099.trx.part1 2> /dev/null
mtd write MI-3_3.4.3.9-099.trx.part1 kernel1
dd if=MI-3_3.4.3.9-099.trx bs=4194304 skip=1 2> /dev/null | dd of=MI-3_3.4.3.9-099.trx.part2 2> /dev/null
mtd write MI-3_3.4.3.9-099.trx.part2 rootfs0
nvram set flag_last_success=1
nvram commit

写入patr2时出错，显示[e]，执行以下语句，并用u盘刷官方固件

nvram set flag_last_success=0
nvram set flag_try_sys1_failed=1
nvram set flag_try_sys2_failed=1
nvram commit

重启路由

在putty中执行命令
reboot

等待重启完成即可进后台，后台ip是192.168.123.1，用户名和密码都是admin

四、刷入OpenWrt固件

开启ssh后（做完上面第二步），使用winscp上传openwrt-ramips-mt7620-xiaomi_miwifi-r3-squashfs-kernel1.bin和openwrt-ramips-mt7620-xiaomi_miwifi-r3-squashfs-rootfs0.bin到路由器tmp目录，执行下面命令：

cd /tmp
nvram set flag_last_success=1
nvram set boot_wait=on
nvram set uart_en=1
nvram commit
mtd write openwrt-ramips-mt7620-xiaomi_miwifi-r3-squashfs-kernel1.bin kernel1
mtd write openwrt-ramips-mt7620-xiaomi_miwifi-r3-squashfs-rootfs0.bin rootfs0
reboot
