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.

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.

LOGS LOGS LOGS!!!!

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://xdaforums.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!

I don't think so, lineage is pretty much the closest rom to stock aosp, I may be wrong tho. Anyway if you're rooted there's a magisk module to hide the gesture bar

Hi to all!

I face a strange problem and i'd like to ask you is someone have the same.

When i choose

Security>>Device Security>Screen Lock>None

after 15 sec (the limit that i put to screen off) while my screen is off, suddenly light up again and after 15 sec goes off and light up again and .... this is happen to infinity....

If i press the power button (on-off button on the right of the device),

the screen goes off without light up again

.

If i choose

Security>>Device Security>Screen Lock>Swipe,

the screen also

goes off without light up again

.

Can someone help me please to stop screen goes off - on when i choose "None" to Screen Lock?

Hi, I'd like to know if this Rom is also for the 5G variant. I know it states all variants but I'm not sure if this includes the 5G models
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] fpozar:
It means all the perseus variants. Perseus is the non 5G model. In fact, I believe they only share the look. I might be wrong but andromeda (5g mix 3) is based on a newer snapdragon chip making development on perseus not immediately useful for andromeda. Sure, since it's open source you might be able to salvage some code, but no, it almost certanly (if I'm correct about them being actually different hardware) won't work out of the box.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] ilya_m:
I just recently switched from official and missed this rom. are there any updates or news?
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] PerplexityJeff:
I do hope that this will receive updates and maybe even get into LineageOS Official but we'll see we can only hope.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] adam900710:
Boot loop here.

Not sure what I have done wrong.

Chinese non-5G version, boot loader already unlocked.

The phone has been updated to V11.0.3.0.QEEMIXM using global official fastboot rom.

Hasn't encrypted the phone, just copied lineageos and gapps, nor logged into any account.

Then flashed TWRP, wiped system, data, cache, flased lineage os along with gapps.

The result is boot looping, no booting animation, just MI with unlocked icon for several seconds, then black screen for one sec, then back to MI screen.

Updated: Without Gapps, the result is the same.

Tried data wipe, no difference.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] adam900710:
Finally got it fixed. It looks like this LOS doesn't like V11.0.3.0.QEEMIXM at all.

Had to go xiaomi.eu v11.0.2.0.QEECNXM first, then go this LOS.

Would be happy to see some firmware version check, just like what official LOS for OnePlus5 does (won't continue if firmware doesn't meet certain requirement).

Any idea?
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] sergej_7:
maybe creating logs will Help to find a fix
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] vq8acsxht:
OK, Just figured out a massive bug that you should all be aware of. As you know, lineage stripped root off of OS which was a BAD MOVE!!! They thought it would be fun to get root access off of magisk (basically mooch off a third party). Well, what you DO NOT WANT TO DO IS: in developers options turn on the advanced re-start options. Then, try to restart the phone into the recovery. If you do, the phone will restart into the lineage OS and give a message "Phone is starting". It will brick the phone. In order to fix this the internal storage has to be formatted. A clean or dirty flash will not fix the phone. So, because the nuts decided to use third party root, your phone becomes a paper weight. The lineage 16 add on root does not root the phone either and does nothing to correct this. So, you have been warned!
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Jaitsu:
That's not specific to this rom. I'm not sure what it is, but booting into any recovery from any rom on this device seems to have a chance of corrupting /data and requiring you to wipe (someone might have some more input on exactly what causes it, but it's definitely not specific to this rom, I get it all the time on just about every rom I've tried)

Also, there's a good reason to use Magisk: the possibility of passing SafetyNet and otherwise hiding root from apps (games, some banking apps, etc) that will give you a hassle if they detect root or that SafetyNet isn't passing. I don't think that's currently possible with system-installed root. (hiding non-Magisk root from normal detection might be possible but you're sure not passing SafetyNet)
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] vq8acsxht:
I do not believe it is corrupting /data. I think it is inserting a partition into the internal storage area. The dev needs to find out why this is occuring because another app in google play store that needs root in order to boot into recovery did the exact same thing.

In the states no one gives a sh|t about some damm banking app that google thinks you may need. Here, you are a real idiot if you pay that way. So, what is to hide? I really do not like Magisk because it depends upon twrp anyway to flash anything. Faster to download the package and then flash it. But yes, I do like hearing other ideas.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] vq8acsxht:
This is not a root problem and can be fixed. It is caused by flashing TWRP over TWRP within TWRP where the recovery partition is not bootable. To fix this a computer and fastboot is needed. In dev options enable android debugging and connect phone to computer via cable. 1) type in teminal "adb devices". (make sure phone is there) 2) type "adb reboot bootloader" (to put phone in fastboot mode). 3) In fastboot mode type "fastboot erase recovery" (which will fix the main problem-remember TWRP is erased). 4) In fastboot mode type "fastboot flash recovery twrp-x.img" (where twrp-x.img" is TWRP which will install twrp in the recovery partition). 5) Reboot into OS type "fastboot reboot".

Now, while in Lineage debugging turn on advanced restart then try rebooting into TWRP. Hopefully this helps someone!

Hi to all. After so many months, i'll move to stock ROM. Could you possibly know any good guide to restore STOCK (Xiaomi eu v12. 0.1) from LineageOS (this ROM) without problems. I am not lazy to search just stressful with my timeframe job.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] joelh:
Laziness or not, this is not the right place for this sort of question. Please make a new thread for that or find an appropriate one to post in.

I've not forgotten this ROM, expect more builds in October.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] inspigr:
All in all it's a question moving from specific ROM to stock. You are the developer, or at least you had started the topic and you done a great job.

Sorry to bother you, but it's (my opinion...) not the solution to open a new thread, asking something "unknown" from people out of this topic!
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Grellenort:
Xiaomi.eu isnt stock, its custom rom. And if you want install official GLOBAL/CHINA rom straight from Xiaomi then you can google tons of guides about MiFlash.
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] inspigr:
Thank you Grellenor for your "valuable answer" with the tons of guides. You know ..... you can post just a link (which is most helpful to me.) without write any of your text. Hope you guys not acting like this in your real life!
[Xiaomi Mi Mix 3 ROMs, Kernels, Recoveries, & Other] Grellenort:

[LG G7 ThinQ  Questions & Answers] strifej:
Hey, did a search but didn't see anything. I have a G7 running ULM20e (sprint cross flashed).

When I'm on a call using Whatsapp or Kakaotalk, the other party can hear their own voice (echo). I never hear any; it's perfect for me. When I switch to speakerphone and keep the volume low, then they DON'T get the echo. With earphones plugged in (iphone style earbuds), they still hear the echo.

Does this sound like a software issue?

I installed a mic app to record voice/sound and when I speak into it, it's fine. No echo, so the mics are operating properly.

Weird, and the gf is getting annoying.. sigh
[LG G7 ThinQ  Questions & Answers] strifej:
Posting my fix for future reference. After some research and lots of software testing (tried 3 differen roms, Oreo and Pie), I believed it to be a "hardware" issue. On youtube, I saw a video that described a fix and I basically did that: https://www.youtube.com/watch?v=FkcxzmCPFWw

I took soft foam and covered the areas around the bottom microphone with it. Both underneath the plastic shield (boombox speaker) and above (just under the back panel). It has reduced the echo to 10-15% of the amount before, but not completely eliminated. I think I can live with that for now.

[Samsung Galaxy S7 Edge Questions and Answers] shah22:
Then stay on stock rom :) its the best one that fits your criteria..

Also depends what you exactly need custom rom for.. you need often to sacrifice on somethings to get another ..

At this point.. if you are new to rooting and custom OS scenario, i recommend staying on stock.. because it is now more complex procedure and gives far more problems sometimes then it gives benefit. Imho the benefits of rooting/custom OSes are degrading slowly to the point where its just a useless hassle..

But ofcourse its everyone's choice.. you want to live on the edge by trying new OSes/new things/features you are free to do.. just make sure you know how to do everything safely, and backing up the vital data, like copying your nv data (the first thing after gaining su access), knowing the correct/safe procedure and please DON'T "ACCIDENTALLY" turn oem unlock off.. :)

I personally recommend gaining su access by SYSYEM LESS methods plus magisk in order to avoid dm verity errors and encryption problems.. it also makes it less likely to mess with your nv data..

See alexndr's system less dev base and custom rom.. its based on stock 8.0 too (i think its all stock) and also stable too :)

https://xdaforums.com/s7-edge/development/rom-dqd1-devbase-v4-1-multi-csc-safe-t3591647/

OR if you want to live on the edge.. backup your nv data and try custom roms like black diamonds, hyper rom, deluxe rom and any other which is being actively updated/supported.. try and find your taste on your own and report problems on their threads (every rom has their problems)

But i would either root stock "system lessly" or flash alexndr's custom systemless OS devbase :)
