Thank you for the excellent work. I installed it sucessfully on a 4/128 Redmi Note 9 Merlin:
- Unlock via MiUnlock
- Downgrade 12.0.5 to 12.0.3 Global ROM via MiFlash
- Install TRWP 3.4.1b-0606 (for RedMi 10x by by wzsx150)
- Wipe by format (data, cache, dalvik)
- Install LineageOS 17.1 20210209, Gapps via TWRP
- Install Magisk 21.4 via TWRP

Just one little thing: I could not get the Aux Cams to work with any GCam config. Would somebody please upload a Xiaomi Redmi Note 9 Stock Camera APK extracted from the stock ROM?

Camera app urgently needed :)
If I'm understanding well, that TWRP is only for A10 roms right?

Redmi Note 9
this is the best way to restore your phone
Good luck
thanks for your help. I will try soon to bring my phone back to its stock rom. But what should i do next time to not make the same mistake? is there an ultimate guide? Thanks again

One question: should i install the 12.0.6.0 version or 12.07 ? i found that 12.0.7.0 is too new and doesnt have that much support. Does it even matter?

All the LineageOS 17.1 20210209 links are dead.

I still had the file on my system:

However, you should probably consider a different and more recent ROM at this point in time. This one is almost half a year old, and not getting any updates. How much time will you get out of it before the lack of security patches becomes an issue? I liked it, but moved away from it some ago due to that very reason.

Thanks! What did you move to by the way? I can't seem to find any more recent lineageos roms for redmi note 9. Are you using another distro?

I'm currently on Kraken, because it was the most recent at the time. But it's getting a little bit stale, so I'm not sure I'd start using it now.

The most recent LineageOS I'm aware of is CommunOS' Lineage 18.1 from May: https://forum.xda-developers.com/t/...redmi-10x-4g-unofficial.4244657/post-85083767

Perhaps worth a look are any official ROMs, because they'll probably receive more regular updates (although you never know). This one seems quite recent, but I haven't tried it myself yet: https://forum.xda-developers.com/t/rom-11-official-pixel-extended-oss-redmi-note-9-merlin.4295499/

    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.

    Code:
    /*
    * Your warranty is now void.
    *
    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at me for messing up your device, I will laugh at you.
    */

    What's working :
    • Audio
    • Bluetooth
    • Camera
    • EGL
    • GPS
    • RIL (Calls, SMS, Data)
    • Sensors
    • Video Playback
    • Wi-Fi
    • MTP

    Known issues/Bugs :
    • Double Tap to Wake
    • Brightness slider
    • Encryption
    • WiFi Calling
    • VoLTE
    • Selinux is permissive(Temporary. Will soon make it enforcing)
    • You tell me the rest:)
    Reporting Bugs
    DO NOT Report bugs if you're running a custom kernel or you installed any root implementation
    Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
    If it is a random reboot, grab /sys/fs/pstore/console-ramoops and /sys/fs/pstore/dmesg-ramoops-0. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless). Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.

    Instructions
    • Have custom recovery installed
    • Download the latest LineageOS Build and GApps(Optional)
    • Wipe Data
    • Flash the ROM and GApps(Optional)
    • Enjoy the rom
