I flashed lineage 18.1 zip and MindTheGapps.zip together. Lineage is installed but cannot find google service. I tried to reboot to recovery mode but I am stuck on Glitch splash screen. I tried flashing twrp and recovery with fastboot but no luck.

what are the benefits over unofficial other than updates?
are the issues fixed?

Is the camera working well?
GPS connectivity?
Bluetooth?
IR Blaster?
overheating?
random crashes?

any experience on these issues known with unofficial?

Not sure if this is my device being dumb.. I try to update to the 18.1 Lineage recovery to update to the new rom and I keep getting "writing recovery FAILED (remote: unknown command)" in fastboot, tried 3 different laptops, 2 different versions of fastboot, 2 different USB cables, disabling screen lock and stuff on the 17.1 rom still installed.. Not sure why I cannot get it to push.

Did a fresh install on an h918 of lineage-18.1-20210408-nightly-h918 with TWRP 3.5.2_9-0-h918, MindTheGapps-11.0.0-arm-20210328_143701, and Magisk v.22.1 and everything is working smoothly.

Thanks for the new version of Android Linegae OS!
Currently I am using Lineage OS 17.1, do I need to revert back to the stock LG firmware before flashing this ROM?

Спасибо за новую версию ОС Android Linegae!
В настоящее время я использую Lineage OS 17.1, нужно ли мне вернуться к стандартной прошивке LG перед прошивкой этого ПЗУ?
Нет. Но нужно удалить гаппсы 17.1. Протрите систему.

On 04-01, I updated to TWRP 3.5.1 and did a clean install of this ROM (04-01). I wiped & formatted, after making a copy of my internal storage to a PC. The install went great. I reinstalled my apps and then flashed Magisk 22.0. Everything I tried worked well (BT, GPS, quad DAC).

Today, I updated to TWRP 3.5.2 and Magisk 22.1. Then, I dirty flashed the 04-15 nightly. Magisk patched new boot.img automatically and everything is working well.

Thanks to npjohnson and x86cpu for keeping my travel device up-to-date. :)

But mostly, thanks to aleasto !!! (sorry about originally overlooking you).
:)

I just turned my phone on. Using GPS Test (chartcross), I had over 20 satellites in view within 2 seconds. It showed over a dozen satellites 'connected' within 15 seconds. But, it took about a minute to get a 3D fix.
This is indoors, in a single-story structure. It's a clear day.

I don't have any custom kernel or GApps. Just latest of this ROM and Magisk 22.1.

I know this helps you ..... none at all. It's just a data point, in case it matters.

no custom kernel or anything extra either... gonna try another clean load tonight with of course magisk and mindthegapps package and hopefully that fixes else its back to the last build of 17.1 for me for a while :/

UPDATE: A fresh install seems to have fixed GPS (not safetynet yet)... downloaded the newest mindthegapps just in case no idea if that helped or not but GPS working again... I will say however it does take 18.1 a lot longer to get your location than 17.1 did... hopefully this will be fixed some in the future versions :) either way good job LOS team :D

Noob question. Can i install this rom on my h990n?

Before this, i used lgup to downgrade with nougat 990ds aus rom. It installed but got error at setup wizard. Something about modem not compatible. So now i assume 990ds ≠ h990n even though both are similar

    Sad to say that unfortunately due to persistent crashes I had to give up on LOS 18.1 on my h918. I started from scratch after flashing stock KDZ numerous times and no matter what LOS would start crashing. The most recent episode after the latest LOS update started occurring seemingly for no reason in the middle of the night when the phone just kept booting and crashing over and over. Wiping Dalvik/cache had no effect. I simply couldn't take it any more. I never experienced repeated crashes like this on stock.

    I'm on rooted stock 20h now and it is very stable and it's nice to have wifi calling and a few other features also.

    If anyone wants to know how I got to rooted 20h I first flashed 10p using LGUP, then using lafsploit on mAID system installed TWRP. From there I flashed H91820h.zip image (which doesn't overwrite bootloader) and Magisk.

    is there a way i can make the github website create me a massive .zip file i can download with my web browser?
    Definitely not a spec problem since i build it in a laptop with 8GB of RAM (using ZRAM) and a i5 8250U, besides, repo sync isn't even RAM intensive, only the build commands are. I suppose it must be something in their server.

    And unfortunately no, the github address only stores lineage's pointers to the actual files, not the files themselves (github has a repository size limit, and lineage can very well use around 100GB on disk just for the 18.1 branch). I will try a repo sync here just to check if it really is their server.

    guide works fine - the accusatory tone won't get you anywhere.

    Delete the build tree, check your internet connection, and restart the guide.

    Those errors mean you've been rate limited by google's site for some reason, and the latter one means the .git folder of that repo is corrupted. Like I said, just restart.

    On my LG v20 H910 with LOS 18.1 lineage-18.1-20210722-nightly-h910-signed.zip
    (nothing else installed, no gapps, no mods, no root, etc...) the "LOS SNAP CAMERA" VIDEO record sound volume is almost 0%

    SAME ISSUE ON Lg v20 H918 !!!!!!! I have that phone also.

    After days of research and playing with mixer_paths_tasha.xml settings I gave up..... PROBLEM VERIFIED: its a LOS snap camera apk issue.

    Then I installed ROM [android 11] UNOFFICIAL SuperiorOS-Xcalibur

    https://forum.xda-developers.com/t/...96-11-unofficial-superioros-xcalibur.4248255/

    COMING FROM LINEAGE/RR:

    1. Boot into twrp
    2. Do a regular wipe (not format)
    3. Flash Superior zip
    4. Flash magisk (optional but recommended)
    5. Wipe dalvik
    6. Reboot

    CAMERA VIEDO WORKS PERFECT !!!!
    PERFECT SOUND !!!



    To LOS maintainers: Fix the LOS SNAP CAMERA apk or quit screwing around with programming android ROMs. Simple as that. I am a MSEE engineering manager and if I cant do my job right I don't do it at all.


    The LOS snap camera has been broken for a very long time (years) and many people have had to use GCAM or Open Camera and all these people including myself are sick that LOS maintainers can't fix a simple but very important apk in LOS (CAMERA video sound issue). This is well documented all over LOS wiki and github etc.....

    "Hi @npjohnson
    Open Camera (and BSG GCam 8.1) uses unprocessed-mic by default to get audio while recording video."


    I am done with LOS until this is fixed. YOU ARE WASTING MY TIME
    Yeah, considering h910/h918 are near identical, makes sense that they both suffer.

    By your own statement, you're an engineer, and should be able to discern based on the info you gave me that it is _not_ an issue with the "Snap Camera apk", instead that we are using compressed audio path, and clearly it isn't processing right (likely a codec issue like I mentioned several posts ago). We could swap it to unprocessed mic input, but that will be garbled and awful - only using that as a last resort as opposed to actually fixing the compressed audio route.

    As for the insults launched - k, stop using lineage then. I literally have not a care in the world whether you use it. I'm doing hard work for free, which, as an engineer, you should understand is often thankless, and your naggy/attacking comments only make me want to never touch the device again :)

    I'll be looking at it sometime this week, but for everyone else on this thread who has been kind and supportive lol.

    Maybe you should go back to stock? You do realize we do this for free and on our own time? If there are any issues we try to fix them ASAP but with your comments I doubt @npjohnson is going to want to support the device anymore. If there is any issue I would recommend reporting it in a less-hostile way and it might be a simple fix rather than insulting the primary dev for LOS on the device who may now not want to support the device anymore...

    Thread slightly cleaned!

    This is a development site and people contribute work as a fun hobby, NOT A JOB! They don't owe you anything but you owe the developers respect!
    If a ROM does not work for you, what did you do to contribute? Did you clean flash? More important, did you run a log of errors to help the developer? Just remember what you would expect in your profession. Or were you just too lazy to help and prefer to leech and complain?
    This world will only get better if we all learn to give instead of always taking! Please do not comment on rude posts, please report and a moderator will help.

    So, my girlfriend is at home, asked her to try it - and surprise surprise, Snap Camera's video recorded audio works just fine lol. Front and rear camera.

    I did pick the patchset we merged on g5-common though afterwards, and merged it - it sounds to loud to me tbh, but enough people seem to like it better, lets go with it.
