@joelh I'm trying to build my own build directly from sources and I got it to boot up but the camera is crashing because it can conntect with cammeraservice. Any trick or idea of where to look for?

    LineageOS is a free, community built, aftermarket firmware distribution of Android 10 (Q), which is designed to increase performance and reliability over stock Android for your device.

    #include <std_disclaimer.h>
     * Your warranty is now void.
     * We are 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 us for messing up your device, we will laugh at you.

    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.

    GPL compliance:
    • Almost everything

    • You tell me

    Compatible with all Xiaomi Mi MIX 3 variants.
    Builds are based off the Xiaomi Android 10 firmware with proprietary blobs from MIUI v11.0.3.0 global stable package.​


    • 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 MIX 3)
    • Wipe /system, /data and /cache
    • Install LineageOS zip package
    • Install [optional] a Google Apps package of your choice (Open GApps is advisable, but stock and super variants are not recommended!!!)
    Important notes:
    • * Required * firmware version must be based on MIUI Q-based builds.
    • GApps can only be flashed on clean installs.
    • Formatting data (all user data is wiped, including internal storage) is a must if MIUI was previously installed and device was encrypted.

    Credits & collaborations:
    All LineageOS team would like to thank everyone involved in helping with testing, coding, debugging & documenting! Enjoy!​

    Other Issues?

    Before posting on this thread, make sure of a few things:
    You've utilized the search function of the forums. Nothing irritates us more than lazy people who do not search for an answer before asking or ask the same question over and over again.
    If you are the only one having a problem: boot into recovery, wipe data/factory reset, reflash the rom/gapps and nothing else. Boot up and see if the problem persists.

    Press BOTH volume keys + power key - it will vibrate very short. Wait until a notification appears that the bugreport is ready, send it to your mail and post it.
    Alternatively go to dev options (press "build number" in "About phone" 7 times to activate it), activate the switch "Bug report shortcut", then go to Settings->Keys->Power key and activate it there as well. Long press power-key and then use the new menu item.
    * [url='https://forum.xda-developers.com/showthread.php?t=2774386"]how to grab logcat[/url]

    Only if rooted:
    Use this: SysLog by Tortel

    If you have a hard reboot (to the vendor boot logo, not the LineageOS boot logo), use adb or any other file explorer tool to pull a copy of "console-ramoops" after the reboot and provide that.

    adb pull /sys/fs/pstore/console-ramoops

    Note: We will not support any kind of modification on the ROM not done by our sources. If you are running XPosed, Kernel Booster or whatever occurs to you, we won't support you in any way. The problem will in every case be treated as the additional softwares' fault (because often it is!)

    Important note

    This is a development thread. This means it is NOT your personal support thread.
    Questions about anything not related to LineageOS on perseus (Mi Mix 3) will not be accepted nor be answered.
    This includes topics like going back to stock, problems with third-party apps (e.g. Snapchat), ...
    Also do not encourage people with such questions by answering them but report them to keep the thread clean!

    How does this version of Lineage 17.1 from other Lineage ROMs for the MiMix3? What are your plans for releases/updates? Is this going to be a one and done type of rom?

    lineage team is pretty strict about how their roms are maintained. The dev also said it'll be Nightly so no worry

    This will be the official support thread.
    There is a time i though that development scene for Mi Mix 3 was dead. Thanks!. Do you have paypal so we can donate?

    Thank you for the offer, I don't personally take donations but you can always donate to the LOS project:
