I installed an OTA update today. (device: h990-ds)

I have to thank the DEV for keeping this device up and running and working on it.
but the problem is that remaining issues we speak about here, are not even considered in any of the updates from almost first unofficial release till now and that is very frustrating. :(

I mean why should a user struggle on basic needs of a daily driver? like BT connection? GPS connection?
aren't they more important than updating lineage wizard script for TV??

and why aren't any of them mentioned in the first post? known bugs? just volte?

I can name 8-10 issues and bugs!

please at least consider looking at them :(

bcs maybe you are the only one encountering these problems?

i don't mean to be mean, but it maybe the truth

btw, h990ds is not officially supported, although a friend has said it works just fine (https://forum.xda-developers.com/t/official-lineageos-18-1-for-the-lg-v20.4255323/post-85892415)

maybe you can ask him

i think either your hardware is defect (if they work on another rom, then it's not), or if the firmware isnot compatible...

maybe if you provide some logs to the dev he can fix them, but just complaining wouldn't help bcs the dev cannot reproduce the errors it seems

What v20 model do you have
h910

When I enable "WIFI Verbose" in developer options the WIFI stays connected but the setting app is unavailable and unable to access the wifi setting by tapping on wifi. When I enabled this setting before it caused many systemUI crashes. So unable to access the setting app really sucks.

Good news: Your H910 can be fixed
Bad news: There is no kdz for the H910, BUT you can use US99610f_00_1205.kdz

My recommendation:
Option A: Road to LOS 18.1
1) Boot into downloader and flash US99610f_00_1205.kdz with LGUP and reboot, phone will work perfect. This will set up partitions and LG framwork files correctly
2) Unlock bootloader and install TWRP
3) Flash h910-10r.zip via TWRP >>>DO NOT reboot
4) FORMAT DATA >>> DO NOT reboot
5) Flash LOS 18.1 and MindTheGapps-11.0.0-arm64-20210328_143848 and reboot
6) IF needed flash H910 nugut modem. I cant remember if this is necessary but possible

Option B: Oreo with no ATT crap
1) Flash US99620f_00_1120.kdz with LGUP

Done.......

I have the LG V20 910(AT&T Model). I am trying to opening up the boot loader so I can install TWRP and then Lineage OS on it.

The instructions say to follow this guide to open up the boot loader but some of the downloads are no longer available.


What Is the current best way to unlock the bootloader? These phones have never had any custom software loaded and them and they have never been updated.

I should be clear. The phones need to be rolled back because its security patch is Mar 2017 and November 2017. They can be rolled back so that is not a problem. The problem is the guide I was following and linked can't be followed because some of the downloads are missing. Once this is done, I can then follow the guide you linked.

NOTE: You do not need to install anything. Unzip the file and follow pdf instructions. I have omitted root instructions. I have included info that the other websites forget to mention. Also ignore step 1, but I follow step 1 for reasons I cant remember.

It says to flash US99610f_00_1205.kdz but that file is not included in the zip you said to download.

IR works on any rom as long as you get a kernel that supports it. For now, only gamma has working IR (and only a specific version that i tested while trying to find a fix for it on lineage kernels, but it's quite outdated and might have other bugs with newer android versions although i didn't face any during my testings).

Thanks for the info. Curreny I am using PE with gamma. 3 things I notice is 1. Using gamma the phone is sometimes getting really hot. 2. It drains the battery compared to PE built in kernell. 3. Every 2 or 3 days I.get green kernel.panic. so if I switch to LOS, will I be facing.those problems also? Thanks

Not really, you'll only face abnormal battery drain and high temps if you push the device (some other kernels are better at this, but lineage is good enough for most cases). Green kernel panics also shouldn't happen at all on LOS stock kernel from what i've tested.

Ok if I install LOS with gamma, will I face the probles I said above? Thanks…

    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

    BTW, I wonder if it's advisable to upgrade the baseband (and how) on LOS18?

    For example, one V20 is running m8996faaaanazm-1.77269.3.79643.3
    Nah, if your current one works, keep it, v20 can be finicky.

    Will you working on Lineage OS 19?
    We are far, far, very far from that. Our device trees are simply too outdated for a12 to even get past the lg logo. Only hope of even booting a12 is a significant upgrade for the kernel, device trees and device firmware. All of which will take time, lots of it.

    This link seems to be dead now, any suggestion?
    It is? Weird, i just entered the AFH link right now and there's a mirror to download the modem.img file.

    In any case, if AFH can't find any mirrors for you i think i still have that file somewhere on my phone. I'll see if i can upload it later.

    ahhh i didn't know that, i though it was a h910 so i unlocked/rooted using the common root method, is there anyway to revert and "officially" unlock it now?

    static screen doesn't bother me that much though

    wifi instability is more of a problem

    ahh i just checked lg has stopped the bootloader unlock service
    Yep, unfortunately they seem to have closed that service, so the best approach you have is using that us996 rom with the modem that works best for you and also a h910 kernel to solve that screen glitch at boot. I don't think the h910 kernel will break things on your us996 since they're basically identical except for that unlock procedure.

    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.
