xiaomi r4a install padavan

最近换了个小米的路由，想着登录ssh，能在路由上跑一些小的定时任务。但是无奈，绑定不通过，那就直接刷机了。

一开始是按照csdn上的文章刷opewrt的，但是都不成功，最后换成 老毛子Padavan 了。

# 步骤描述

# 获取root权限

使用 WSL Ubuntu 进行访问，python3已经安装了。

winse@LAPTOP-I9ECVAQ4:OpenWRTInvasion-master$ python3 --version
Python 3.8.5

# https://github.com/acecilia/OpenWRTInvasion
winse@LAPTOP-I9ECVAQ4:OpenWRTInvasion-master$ ls
Dockerfile  readme                                     requirements.txt  set_english.py
extras      README.md                                  script.sh         speedtest_urls_template.xml
firmwares   remote_command_execution_vulnerability.py  script_tools      tcp_file_server.py

winse@LAPTOP-I9ECVAQ4:OpenWRTInvasion-master$ sudo apt install python3-pip

winse@LAPTOP-I9ECVAQ4:OpenWRTInvasion-master$ pip3 install -r requirements.txt
Requirement already satisfied: requests in /usr/lib/python3/dist-packages (from -r requirements.txt (line 1)) (2.22.0)

# stok获取：登录web访问后，浏览器的地址上就有stok的参数。

winse@LAPTOP-I9ECVAQ4:OpenWRTInvasion-master$ python3 remote_command_execution_vulnerability.py
Router IP address [press enter for using the default 'miwifi.com']:
Enter router admin password: __xxx__
There two options to provide the files needed for invasion:
   1. Use a local TCP file server runing on random port to provide files in local directory `script_tools`.
   2. Download needed files from remote github repository. (choose this option only if github is accessable inside router device.)
Which option do you prefer? (default: 1)
****************
router_ip_address: miwifi.com
stok: __xxx__
file provider: local file server
****************
start uploading config file...
start exec command...
local file server is runing on 0.0.0.0:1135. root='script_tools'
local file server is getting 'busybox-mipsel' for 192.168.31.1.
local file server is getting 'dropbearStaticMipsel.tar.bz2' for 192.168.31.1.
done! Now you can connect to the router using several options: (user: root, password: root)
* telnet miwifi.com
* ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -c 3des-cbc -o UserKnownHostsFile=/dev/null root@miwifi.com
* ftp: using a program like cyberduck

winse@LAPTOP-I9ECVAQ4:OpenWRTInvasion-master$ ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -c 3des-cbc -o UserKnownHostsFile=/dev/null root@miwifi.com
The authenticity of host 'miwifi.com (192.168.31.1)' can't be established.
RSA key fingerprint is SHA256:AT91yqVuqPnmOO5wmke6V0Hl67GKXdkb48W/FU3WfEM.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'miwifi.com,192.168.31.1' (RSA) to the list of known hosts.

# 安装breed

用WinSCP登入路由，使用 ftp协议 ，ip地址 miwifi.com ，账号 root，把 breed-mt7621-pbr-m1.bin 文件上传到tmp文件夹内，之后执行如下命令：

root@XiaoQiang:~# cd /tmp
root@XiaoQiang:/tmp# ls breed-mt7621-pbr-*
breed-mt7621-pbr-m1.bin

root@XiaoQiang:/tmp# mtd -r write breed-mt7621-pbr-m1.bin Bootloader
Unlocking Bootloader ...

Writing from breed-mt7621-pbr-m1.bin to Bootloader ...
Rebooting ...

接上网线，再等一阵子（1,2分钟），然后访问 http://192.168.1.1/ 。

# 刷padavan

下载r4a版本的padavan: https://opt.cn2qq.com/padavan/

MI-R4A_3.4.3.9-099.trx

访问 192.168.1.1 ，备份eeprom和固件（重要），然后勾选固件，然后将小米4A的trx固件文件进行上传，然后完成固件更新流程。

更新过程请不要切断路由电源！更新完成后, 页面并不会自动刷新, 自己尝试能否进入路由配置页面。。

刷完后，这里需要多等待一点时间，耐心一点。
