Did you have magisk installed ? You can try to flash magisk uninstaller in TWRP

But i spontaneous switched to Pixel Experience. For now it works better

If I stay on a phone call for longer than around 30 mins it reboots to lineage logo. Just noticed as I dont often speak on the phone for long.

Is it possible to flash the new official Havoc OS over this ROM via TWRP by any chance or is the full method from scratch required?

Thanks for working on this.

I'm waiting for the official build too.

Unfortunately this device will never get an official version of LineageOS. From the device dev inkypen:

"Notice how none of the Xiaomi SD855 devices (raphael, davinci, cepheus) have an official LOS build? The stuff required to get LOS working properly goes against their Terms of Conduct, so none of these devices will get official builds unfortunately.

Required changes to display HAL have already been rejected by peer review.

But the biggest problem is vendor blobs, Terms of Conduct make it clear that only original device blobs extracted from stock firmware are usable. Any of the updated CAF blobs generally come from a BSP leak which is a big no no. Unfortunately we need CAF graphics stack to get rid of Xiaomi display feature (which is the root cause of all the colour issues)"

Would have to take the issue up with the LOS team but it's a risk for them using copyrighted code.

Hi,

I'm using a development chip but this rom didn't identify the mobile options. If I change the chip, all works fine. Somebody can help me?

Since recently we got MIUI12, is the new vendor blobs still not usable?

MIUI 12 on this device is little more than a themed version of MIUI 10. It updated a few drivers, DSP & modem too but nothing much changed. Official LOS is never going to happen on this phone.

Unofficial LOS is available and as soon as a working device tree for A11 is available LOS 18 will follow shortly after. Other than OTA updates there's no benefit to official builds. Updating manually only takes a minute anyway...

Inkypen adds all of his build material and sources to his GitHub if you're worried about security, anybody is free to see everything used in all of his ROMs.

Hey Inkypen I've been trying your lineage 18 build but i can't seem to install it with magisk. Whenever I try to install magisk I get in to a bootloop or just boots back to recovery. Is this a known issue or is it just on my end?

Sorry guys, I've been quiet on the XDA forum because the telegram support group is just faster and more convenient. As some of you have seen I've been working on Lineage 18. The latest build has almost everything working including 5G.

In relation to Magisk, many devices seem to have a problem with A11 and Magisk. I have discovered a method to get it to work though:

Boot into recovery and flash Magisk 20.4 then reboot.

Phone will loop on Mi/Mix logo.

Boot back into recovery and flash Magisk 21.1 then reboot.

Worked like a charm. Thanks for building all these ROMs for mi mix 3 5g.

Hi all.

I'm truly stuck. Have had issues where I'm not able to charge properly, where charging in Android happens very slowly, and I'm talking 100mA according to Ampere.

I came from Pixel Experience (Android 10) where this was an issue identified and fixed. I still had issues. This was why I left.

Clean installed, just tried LineageOS (Android 11) and am having the same issues.

I'm truly stuck. Have been told in the past to charge in Recovery which does work. Unfortunately, I'm a food delivery driver so I often use my device on-the-go for my work. I can't use my phone like this.

Thoughts?

Hey Piovendder,

Yeah the Gapps thing stumped me too for a bit.

Opengapps mentioned using Sourceforge instead of GitHub for their builds in the blog section of their website.

If you follow it, there you will find Beta versions of Gapps for Android 11. 😉

Hope this helps!

Thanks for the reply, I managed to get a working set of gapps off a Google search lol. Unfortunately the 18.0 version of Lineage rom is very buggy. Out of curiosity I tried the pixel experience 11 rom, which surprisingly runs very well! Been using that for a while now with hardly any issues.

    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.

    Code:
    #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.

    Working:
    Almost everything

    Broken:
    You tell me

    Compatibility:
    This is for Mi Mix 3 5G (andromeda) only. Not compatible with regular Mix 3 (perseus)

    Downloads:
    https://sourceforge.net/projects/xiaomi-andromeda/files/

    Installation:
    Reboot to recovery
    Wipe /system, /vendor, /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:
    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.

    Additional installation instructions if coming from stock MIUI:

    In order to install a custom ROM you must have an unlocked bootloader. You can apply for this at Xiaomi's official site: https://en.miui.com/unlock/

    You then need to install a custom recovery. Official TWRP builds are available, and the official maintainer has a thread with installation instructions here: https://forum.xda-developers.com/mi...covery-unofficial-twrp-xiaomi-mi-mix-t3941867

    Once you have TWRP installed, boot into recovery mode. Wipe cache,dalvik,system,vendor partitions.

    You are strongly advised to flash the latest modem firmware. You can grab that here: https://sourceforge.net/projects/xiaomi-andromeda/files/firmware.zip/download

    WARNING: You will lose all saved files on your internal storage in the next step, make a backup of important files before proceeding

    Data partition must be formatted (not wiped) to remove forced encryption. Use the bottom right "Format Data" button in the Wipe menu. You will be asked to type "yes" to confirm your choice.

    At this point your internal storage will be empty. Copy the ROM from your PC to the phone, click install in TWRP and select the ROM. If you wish to install gapps/nanodroid, copy it to the phone and install after the ROM. Once you have flashed the ROM and any add ons, you must format internal storage again. Internal storage must be completely empty for the very first custom ROM boot, once a custom ROM has been installed and you want to swap to a different one, further formatting is not necessary.

    Reboot back to system and enjoy custom ROM goodness :)

    The LineageOS team have added in Qualcomm's Bluetooth stack so I've uploaded a new build. You probably won't notice any changes because these are "under the hood" improvements, but if you have some high end headphones you may hear a difference!

    Also this build and all future builds have encryption enabled. Unfortunately this means you will need to format your data partition in order to install this build, but this is a one time only thing. I can also confirm that F2FS is working perfectly with encryption if you wish to change filesystems. I can also confirm you can switch to a different ROM without formatting (just the usual wipes) so long as the new ROM you are installing is also encrypted. This change might mean that you can come straight from MIUI without formatting but this is completely untested by me.

    Here's the link, and remember you MUST format internal storage if you are on an unencrypted build:
