Some people here really need to curb their entitlement mentality. The dev is doing this for free, in his spare time.

He literally doesn't have to do this at all if he doesn't feel like it. Just wait or switch to a different rom in the meantime.

Hi everyone
I was trying from yesterday to install the last release but I couldn't install it. At last I try the February release and it works like a charm. Everything works alreasdy until now.but I have a problem in network selection.
When I try to select network manually, unfortunatly it can't be set. Can somebody test it and say the result?

The developer has no obligation to do anything. But since so many people are waiting, it would be nice to say something about what to expect or not. Dont get me wrong, I know he doesnt have to do that just that it would be nice.
Switching to a different rom, you surely know, means set up your phone from start. Since lineage 18.1 was such a good rom many if us, I believe, could wait 2,3 weeks.

Anyway, we know all that. The ROM is great, and it is a very good work from developer. We need only some news about ROM issues, nothing any more. No ETAs, no pressure.

Brillant answer. Ok, so only video playing is broken. No problem with sound, BT, and so on...
Sorry, i don't read that you ask for a list. I have some sound issues long time ago, on all previous builds.

-Sound is shortly broken when minimizing/putting on background YouTube/Spotify...

-Outcoming call doesn't start over BT on my car OEM audio system (using audio systems screen/steering buttons), if phone screen is off and locked. I have to push A2 lite power button and then automatically call process continues.

-Video broken issue not appear over BT for me (last build).

I installed the ROM on my phone yesterday. The latest version
lineage-18.1-20210427-UNOFFICIAL-daisy.zip failed to boot (bootloop).
The previous two releases (20210221, 20210421) boot and look fine at first look. However, I was not able to connect to my wifi (which works of course fine with the stock ROM and other wifi devices, the wifi uses WPA2+3), which unfortunately renders both ROMs useless for me. I am puzzled that I am the only one with this problem. Or is there a trick to get wifi working?
I tried with a fresh stock ROM (latest version available) before flashing lineage.

Xiaomi Mi A2 Lite
Two days ago I spent a ridiculous amount of time installing this ROM on my Mi A2 Lite, but it was totally worth it in the end, so I'll begin with a big THANK YOU to @reujea0 for the ROM itself and to @LinkBoi for the reco that made it possible to flash it.

So I had the same problem as @marcelmi - a bootloop between dastboot and Android One logo on the latest build. After reading the entire thread I decided to load the February build and it works flawlessly.

I'd love to give back to the communty so I wonder: is there a way to somehow investigate why the latest build won't boot and get some juicy logs for you guys?

Also I experienced some very minor bugs, some of which come up in this thread: no viewfinder preview in Google Lens, inability to switch camera HAL mode... And I feel like @Singman33 's idea to list them is a good direction - why don't we track bugs in GitHub?

Maybe you should try this twrp https://forum.xda-developers.com/t/...-twrp-recovery-for-xiaomi-mi-a2-lite.4178901/

After formatting data, wipe everything except sdcard. I put necessary files on sdcard.

And after the step that you install the rom, install twrp installer, too. And before rebooting system, don't forget to change your slot(from reboot menu), and reboot to recovery again. Than i installed gapps and magisk and rebooted system. Everything gone well.
Hello, I have tried the official flash description and the one above, but unfortunately I keep on booting back into Fastboot. Any suggestioins?
PS. What do you mean by "wipe everything". I presume not system, because I tried that to but to no avail.

After a few days, no more reboots needed to solve video issues... it is very strange.... maybe new Magisk version (23.0)?

But audio glitches when minimizing audio related apps, and my personal calling issue over BT in my OEM car audio aren't gone yet.

Soft bricked after update.
TWRP over ADB to boot into Slot B and working again, but I think on old rom (20210421.104824). Update appears on updater again.

What's the issue? What I have to do now to avoid data corruption or data loss and get latest OTA without issues?
Get the newest ota, make sure the rom's file indicates it was built in may(05)

    As requested, here is a beta of the microG version. It looks functional at first sight, should be the same as the non-microg one. Give me feedback if you try it. If it is good will release it. Download this http://transfer.sh/1UtZs3v/$RK4RW1G.zip

    I would like to express my gratitude for all the effort that went into getting LineageOS work A2 Lite 👍
    Indeed wifi calling does not work, will see if I can fix it.
    Hello XDA, I think my problem is solved. I made a fresh install again (full wipe) and used opengapps pico from today. At present, by incomming phone calls displayd this (only above wiith the red and green button. Last time, the phone app was automatily open by incomming phone calls (17.1). Is this new in 18.1?

    Best regards all
    I'm on a clean install on this rom for 24h now and no bugs so far.wifi works ok, Bluetooth pairing is ok too GPS is fine. I've chosen MindTheGapps-11.0.0-arm64-20210412_124247 and everything is fine.
    For the gcam the choice was DMGC_8.2.204_ver.5.0

    LineageOS 18.1 is a free, community built, aftermarket firmware distribution of Android 11/R, 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. You can also view the changelog for a full list of changes & features.

    #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.

    What's working:

    Known issues:
    You tell me

    1. Download the latest build from here
    2. Download LinkBoi00's version of TWRP here
    3. Reboot to bootloader (adb reboot bootloader)
    4. Fastboot into TWRP recovery (fastboot boot twrp*.img)
    5. Do a factory reset in TWRP
    6. Flash the latest build of Lineage OS
    7. Boot into your new phone
    Most of us will want the basic functionality like Google Play, Maps and others, therefore I recommend downloading Gapps. You choose your own, but I recommend OpenGapps. They are among the few that can survive OTA updates. They do not yet have official R builds, but you can yet the beta ones that work fine from here.
    If you do this, I recommend booting into the new LineageOS first, then reboot to recovery, do a factory reset and then only flash the gapps.

    Lyceris-chan (most of this is possible due to him)
    The wider Android community

    Ending words:
    This is a follow-up to the Lineage 17.1 ROM that I was working on. You cannot just upgrade from it to this via the system updater, you have to go through the process above. As said before, this is mostly possible due to Lyceris-chan, go support him. If you have any errors or questions feel free to ask in the thread. As for official status, might happen, probably not, I don't have enough time to make the push. As for MicroG, I plan to publish a build too, keep an eye out on xda. If I failed to credit you, make yourself known.

    By no means is it mandatory, I do this because I find it interesting. But it takes a lot of time and also requires me to have a powerful server, so if you could spare some change, I would be grateful.
    Sorry, for leaving the rom broken and being away for so long. I had important deadlines at school and could no work on this rom. Sorry, from now on things should be much smoother, probably microg build coming in the next month.
    Latest OTA is out, Bluetooth is working and it has the February security patch. Feel free to tell me you got it.
    I have gotten Bluetooth fixed, selinux is enforcing. Building now to see if I can get WFD foxed as well.

    Depending on the results, new build with February OTA might be out today or tomorrow.
    New OTA is out.
