Oh yes, I overlooked that the color can be set there. But it still doesn't work. My most important application for communication is Conversations (XMPP/Jabber) and here it doesn't work either.

I meant the system-wide setting in System Preferences in my previous entry. I cannot set a color here.
I can' t set the color in the settings - the option is missing. However, the function itself seems to work, because in one case the diode flashes white - when I have missed a call. Unfortunately, only here. 😑
You can access the LED-settings throug the search funktion in settings menu.
I didn't find a way another to the LED-settings in this rom.

Oh no, I seem to have to make a misunderstanding. I have the setting for LED of course, but you can't set the LED color there. But I remember some ROM, I think CrDroid 6.6, Android 10, where you could also set the color exactly there. Even for each application. But that is missing here (see picture).

The entire WIFI modem is not working.
I first was having trouble with the setup ('Android setup not responding') but it loaded eventually.
Now the WIFI is broken, if I try to enable it it shows it is enabled, but then I close the notification shade and reopen and the WIFI is still off. If I enable it in Settings the Settings app freezes, same with Hotspot. Bluetooth works fine.
I tried flashing persist.img (https://forum.xda-developers.com/t/...talling-lineage-os-17-1.4202351/post-84201629) but it didn't work.
Can somebody help me with this?

Please follow the install instructions as provided on first page, especialy use the correct firmware from download page, otherwise you get this kind of issues.
I followed the instructions and used the right firmware too. I tried 2 times, but it is not working...
Evolution X 5.5.2 and stock MIUI works fine.

I only see praise for this custom rom, which is the best. Question: Do banking and payment applications like PayPal work correctly?

Okay, thanks. I read the thread under 5.6 and many people found 5.5.2 more stable, and I couldn't install 5.6 in the first place. Then I found out it needs the Xiaomi Android 10 firmware so I will give it a try again.
Hi, i'm using LOS18.1 since 6 month as daily driver without any issue, battery life is 6 days w/o use, under normal circumstances ~2 days, enjoy A11

@ceracz thank you for the rom but i have question in messenger app any bubble chat while typing the keyboard freeze if i pressed (v. b ) it's random but if i opened the app itself there was no problems . and another question i can't give any app full screen permission
I have noticed the same issue with both versions of this ROM. It only exists when using bubbles for chatting. Can it be related to the fingerprint sensor as letter "V" seems to be directly on the same place? But overall, a great ROM that made my phone usable.

    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. 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.

    Special thanks:
    All LineageOS developers (for this famous ROM)

    If Im installing the linage os freshly from stock MIUI, I just need to wipe the system and then install the Linage os package? Awesome work, I am glad to see this phone still supported :)
    Yes... and lineage 19 is on the way.
    Hello, many thanks for the rom, but we need some screenshots.
    Before i try it, what are the bug´s?
    And camera works at 100%, with all funcionalities?
    Thanks in advance.
    Screenshots attached...
    Regarding bugs... Afaik none.

    Camera works at 100%... For features see screenshots.
    this rom is amazing. everything worksout of the box i dont see even the need for updates its perfect. thank you very much dev for your work.
    I found a terrible bug:
    Call dialer is not working properly, i had to replace it by google call dialer app.
    If i try to call someone, i only hear the ringing, i can´t see anything and no way to turn off the call.
    Besides that, it´s working flawless i think!
