XiaoAi Smart Speaker Patcher - Add open source software

duhow

Hello everyone!
Since I discovered the CVE-2020-10263 report regarding XiaoAi Pro LX06, I thought there would be lots of possibilities with the speaker, and so I ordered some speakers and begin testing them.
I'm based at Spain, and I can't speak Chinese, so the speaker as-is is useless for me, since I cannot interact with it.
So I'm currently working in a public repository to add new software that allows me to have my own smart speaker, without having to connect to the Cloud Internet Services, and extending functionality, by adding MPD music player, multi-room audio with Snapcast, and more!


As I see this forum has lots of posts regarding Mi Speakers, I thought it would be good to share the repository with you, so you can test it if you want and provide some feedback and improvements.
[/!\] Please be aware that this will patching will remove all MiBrain and related Mi Services, so you will not be able to use the default voice assistant.

Link: https://github.com/duhow/xiaoai-patch

Default patching includes following changes:
- Enable SSH and ssh-keys in /data/ssh, so you can login without password
- Remove mico, MiBrain services
- Allow change Bluetooth name
- Remove Dolby DTS library reference
- Update time NTP after boot finishes
- Update hostname to match the speaker SN, for example LX06-1420 .
- Update SSL CA certificates
- Add custom sounds for different notification sounds
- Custom binaries, volume control, Google TTS

In order to install this patch, you need to extract the rootfs squashfs file - for example on LX06 this is done with dd if=/dev/mtd4 of=/tmp/root.img , then use this as a original file to perform patching.
Once you have build a patched image, apply it on the unused root partition (if you're running on boot0/rootfs0, flash rootfs1), and boot it.

For LX06 I'm currently testing with base image 1.58.15 , newer versions may have different changes and patching may require some additional changes.

Hope you like it, and let me know your opinion. Thanks!

就是这人找到了小爱音箱的一个漏洞，用它重新刷了系统，移除了小米的服务(可以留下小米的服务和小爱同学，但是有可能剩余容量就不够自由发挥了)，然后自己可以向里面添加功能， 比如用snapcast做全屋音乐等。楼主想把它变成一个hub，可以跑自动化和有很多像亚马逊/谷歌音箱的插件。想让大家都去尝试探索这个刷了以后的系统可以干的事情

Thanks for sharing the firmware/patch. It sounds like a big project. IMHO it could be a dealbreaker for most of Chinese users that this patch removes all Mi services. It's like you have a smart speaker and but its voice assistant and relevant features removed without having anything useable to replace with. Voice assistant is quite importatnt to smart speakers nowadays, especially for those non-protable ones so it might be hard to promote that in the Chinese forum unless you can leave the Mi services intact inside. If not, maybe https://community.home-assistant.io/ is a better place to share it and probably could have more feedback there.

Really appreciate it @relliky!
The patching repository is very modular and allows to add and remove changes, so for example, in case you want to keep the Voice Assistant service from Xiaomi, you can delete the following files:
- patches/21_disable_services.patch
- scripts/20_disable_services.sh
- scripts/24_remove_property_bin.sh

And edit the file to not delete the libs:
- scripts/92_copy_build_packages.sh

The thing is, with all the factory content, there's less space available to use, so that limits the amount of programs you can install inside the speaker.

On the other hand, I'm still trying to setup both Home Assistant and some custom application to have a Voice Assitant available. Unfortunately, Mycroft is discarded, since it requires Python and that application itself exceeds the space available in the system drive! So my next options are to have some STT service provided by Vosk via Home Assistant, and Almond to run the commands.
