LineageOS is a free, community built, aftermarket firmware distribution of Android 9.0(Pie), 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.

Broken:
Sepolicy is still permissive
Nothing else

Working:
Camera (and flashlight)
WiFi
Bluetooth
Telephony (Calls and Data)
Audio (Record and Playback)
Video Playback
Sensors
GPS
VoLTE

Compatibility:
Compatible with all Xiaomi Redmi 4A and Redmi 5A variants (16GB / 32GB), other Redmi devices are not supported.
Builds are based off the Xiaomi's Android 7.1 firmware with proprietary blobs from MIUI 8.3.29 dev package.

Downloads:

Notice:
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.

Installation:
Reboot to recovery (Custom TWRP recovery for Redmi 4A - Direct link)
Format /system, /data and /cache
Install LineageOS zip package
Install Magisk 16.4 For root permission
Install [optional] a Google Apps package of your choice (Open GApps is advisable, but stock and super variants are not recommended!!!)

Credits & collaborations:
This work is due to efforts from RedmiDevs founding members that did the full device bring-up. Huge thanks to @tEaM Tentacles for all the help during that bring-up.
Finally, all RedmiDevs & LineageOS team would like to thank everyone involved in helping with testing, coding, debugging & documenting! Enjoy!

Thx developer for porting the backup of lineage is 16.1

But is very buggy all apps crash (even pixel setup)

So I could not able to enter the phone

I tried flashing with out gapps the phone booted up and opened

But all apps crash like gallery, fille explorer etc

The above one is of lineage is 16.0 back up

The carbon ROM backup also had the same type of problems but for the first time it did not even boot up

Plz developer fix these bugs

Would like to see the ROM fully functional in The near future

Yup I tried it

Good but

Apps force close and force crash every time

If you flash gapps you can't even enter the phone

Because the pixel setup crashes

Is it Gapps related bugs or rom related? In several unofficial Lineage 16 for other Redmi devices, most of the bugs are solved after the latest unofficial open gapps is released. 20th Aug build I believe.

Update: here it is https://builds.nezorfla.me/?dir=open...arm64/20180820

I tried flashing with old gapps 20180811 version

When I tried booting into the phone pixel setup was not working and I could not enter in the phone

When I tried with out flashing gapps at first boot

The phone started and was good but all apps crash or force close

So practically if you want to know how android p will be u can use that for just seeing it


But currently you cant use it as daily driver
