LineageOS is a free, community built, aftermarket firmware distribution of Android 10, which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
Base source code is available in the LineageOS Github repo. And if you would like to contribute to the project, please visit our Gerrit Code Review.
Recommended firmware is latest MIUI stable firmware.
No custom kernels are supported in this thread. Only stock kernel and official builds will be supported. No bug reports if that's not the case.
Reboot to recovery (TWRP recovery for Mi 8)
Format /system, /data and /cache
Install MIUI firmware
Install LineageOS zip package
Install [optional] a Google Apps package of your choice
* Required * firmware version must be based on MIUI *-based builds.
Formatting data (all user data is wiped, including internal storage) is a must if MIUI was previously installed and device was encrypted.
All LineageOS team would like to thank everyone involved in helping with testing, coding, debugging & documenting! Enjoy!
so the newest build 04/11/2019 uses Xiaomi Q blobs.
Therefore it has some bugs:
I havent got bluetooth audio working yet. Bluetooth calls seem to work fine though.
Sound: Speaker works if you make a phone call first and switch to speaker during the call. After that everything else starts working.
Edit: fixed. - GPS all satellites should show up now.
Android Auto fixes probably havent been added yet to lineage but when anything shows up I'll add it.
The reason this build took so long to be released is that Q radio blobs kept causing a reboot when data was used and switched to low power mode. I believe I have fixed this.
Also fyi I'd hoped to have anther build up by now but since lineage has changed to 17.1 branches instead of 17.0 my build system is a bit of a mess. Waiting for all the repos to be updated to 17.1 before releasing anything. Hopefully it wont be too long...
