[ROM][UNOFFICIAL] LineageOS 17.1 for Redmi Note 9S

[EmiriUchi]

THERE IS AN OFFICIAL BUILD NOW, USE THAT INSTEAD!
​

Note: this ROM is derived from LeddaZ's build. I will continue to update it until my 9s is on its last legs. Do not expect any features to be added.

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. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

What's not working:

• Widevine L1
• Some users may face "idle freeze" bug (phone reboots after a few minutes with the screen off). If it happens try to change kernel.

Instructions:

• Download the latest build and GApps (optional)
• Reboot to recovery
• Wipe cache/dalvik and format data
• Flash the latest build and GApps (optional)
• Reboot

Downloads:

• LineageOS
• Lineage Recovery (optional, you can use any custom recovery)
• mauronofrio's TWRP (recommended for OTA if/when it's added)
• GApps (OpenGApps arm64 10.0 nano recommended)
• Firmware for curtana, joyeuse, excalibur, gram (download the last version for Android 10)

Notes:

• GApps are not included
• ANXCam v190 reportedly works with all features
• SafetyNet should always pass, if not use MagiskHide
• The build codename is curtana but the ROM reportedly works for all miatoll devices
• If you use Lineage Recovery make sure to mount /system before flashing GApps and Magisk
• If you want Magisk, flash it after the first boot
• If you want to update the ROM, make sure to disable ANXCam before flashing, you can re-enable it after the update
• Use latest global firmware for curtana and joyeuse, Indian firmware for excalibur and gram

Source code:

• LineageOS
• Device tree
• Kernel source
• Vendor tree

Thanks to everyone that contributed to the original xiaomi-sm6250-devs trees

If I use LeddaZ build: Do I have to clean flash or will a dirty flash work?!

I've personally just done a dirty flash with no issues (as far as I can tell).

Which one from @LeddaZ did you upgrade from? I'm still running version ...20210117 and I'm in doubt whether I need to upgrade to the last one from leddaz before flashing this one.

I had their final build installed before trying mine. It should be fine without it, but if you're paranoid flash that first.

Very good and snappy ROM. Thank you EmiriUchi.

I second that, @EmiriUchi ! I know it's a lot of work, but if you could do that, it would be great. Of course just rebuilding it here and sharing it with us is already great, thank you again for that.
