but on stock it's no problem so i think it's some interaction between kernel and firmware, we may pick one firmware and work on it?

@A.Whit what do u think?
It works on stock, and that's exactly the problem. We can deal with the phone's rom and kernel sides, but the firmware is a proprietary blackbox that we have no actual access to, unlike LG with their stock rom to which the firmware was tailor-made to. We can only send things in so that it can send results out, we don't know what it does with the interface code we have on the rom and kernel any deeper than surface level, and surely we can't simply brute-force our way through by testing every possible combination of blobs/kernel configs/firmware version, etc. About using a specific firmware and working around it... that's kinda what @npjohnson is doing by recommending that people use the nougat firmwares on the first few posts. They're the ones that are known to work the best until now, and those proprietary files are also the reason we still don't (and likely will never have) VoLTE and Wi-Fi Calling on the V20's custom roms unless a genius manages to reverse-engineer the frameworks in a way that allows them to work on customs.

I mean, maybe there's a decrypted and "tweakable" firmware out there, but if there is one, i didn't find it yet and messing with those things isn't exactly legal, so the most we can do is work around the firmware with the tools we have, and that's what we're doing.

But here's the thing: Most of my knowledge is on the kernel side of things, if anyone more knowledgeable than me, especially with roms can clear some things up, i'd really appreciate it.

thx!

1. right now h910-10r modem seems to be okish for my wifi only use. not perfect but not too bad...
2. gpu driver await dev to fix thx
3. twrp seems i'm not the only one... https://github.com/TeamWin/android_device_lge_h990/issues

umm.... i may have found the culprit... my 2 h910 seem to be generating the same randomized mac addresses nd so when they're both on they keep disconnecting the other from the wifi network....

their device mac are different so i have no idea why they keep generating the same randomized mac address

any idea?

right now, both devices use this randomized mac address D0:13:FD:41:AE:6C, and I cannot find anyway to disable randomization.......
Isn't there a developer option for that? I'm currently on my Redmi Note 4X (My V20 is on a barebones Lighthouse ROM for the time being), and it's LOS18.1 has a "WI-Fi-enhanced MAC randomisation" option in there.

Modem doesn't do much for wifi. Wifi blobs are what's causing the issues, makes sense seeing as their old, really old. As for the gpu driver, it's old, but still fine. You can flash a newer driver if you'd like from the adreno team. For twrp decrypt, send a log here.

i am unsure if this is a LineageOS bug or a TWRP one, but is anybody else losing their fingerprint settings after restoring a backup from TWRP?

Now that is weird, chances are slim but i guess possible.
SORRY and SORRY to devs and @npjohnson ! It turns out it's probably the seller who modded the phones before selling and put in same MAC. I finally fixed it by following this guide


So it's TOTALLY unrelated to LOS. 😅😅😅

Last outstanding issues for me.
1. graphic driver https://gitlab.com/LineageOS/issues/android/-/issues/4336
2. twrp decrypt https://github.com/Phoenix591/android_device_lge_h990/issues/1

I just read @npjohnson explanation in the TWRP thread about decryption. Maybe I just switch to Lineage OS recovery instead.
:D

as long as system update can work it should be fine, backup is preferable but not 101% necessary

so now still trying to figure out the gpu driver

    what is a work around to delet or disable the
    "fusedlocation" spyware?

    i do not want that on anyphone i own. there are a few roms i can disable that with but lineage 18 is now softbricked if i delete that spyware.

    i totally understand many people want it.
    i do not want it.
    It is a core part of Android, and not removable.

    It is not spyware. You can go look at the source.
    This is gonna sound silly at this point but here goes: I was never sure how the DAC toggle works. Is it the same as stock roms where it turns it on but with the difference that high impedance is always on?
    Same as stock.

    Can you try lineage recovery? I don't think this would happen there.
    Yes i can test it. I will let you know. Thanks for your effort.

    Does anyone know if LOS 19.1 will be available for the LG V20?
    Nope. Kernel is 3.18 which can't ever properly work with android S.

    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.
    Thank you all for your cooperation.

    Will you working on Lineage OS 19?
    Lineage OS 19 is based on Android 12, so the chance of it even booting on the current 3.18 kernel is very slim, we'll need to update a lot of things including a major kernel version bump to reach a reasonable state to port anything Android 12 so it will likely take a while. Even kernel 4.4 still requires a ton of patching to be able to boot android 12
