I know stock's are pretty old, and LOS hasn't had a GPU driver update in some months now, if you go back through one of the Gerrits for it (or maybe even search this thread) there'll be a commit about them being updated.

From what I've read, the latest ones in the GPU drivers thread are fairly more recent. I don't use them myself since I don't do any gaming on my V20, but I'd look at starting there, flashing them after a ROM re-flash.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Grin59:
I don't wanna clean flash everything so I'll just do a twrp backup and then see what happens if I flash them right after
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
I didn't mean a clean flash. Re-flash the latest version of 15.1 for your variant over your existing one (this is called a Dirty Flash) and then flash the GPU drivers.

If you have a /system problem, flashing the GPU drivers over the top of your current /system won't fix it.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Grin59:
Okay, thanks. I'll do this then

Well flashed the latest Resurrection Remix, which is the one I was on, and then flashed the latest gpu drivers and still am having the same issue.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
If you do a full TWRP backup, dirty flash LOS 15.1 over the top (as well as the to-x86 zip before flashing LOS, assuming that works, which it should) do you still get the issue?

Short of trying it on stock (which probably isn't worth it IMO) I don't know of a way to work out if it's a LineageOS thing or a problem with that app specifically.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Grin59:
I'll try flashing LOS over it tomorrow.

Although on this video, they're playing it while on Lineage and gamma kernel but even when I had lineage installed it still wasn't working. I think I just need the missing file but idk where to obtain it

I have finally managed to get this ROM booted up successfully. Everything worked very well so far, but even if I turn on both "Ambient Display" settings (not sure why there are 2 of them), and put it "always on" mode, I still don't see any ambient display when my phone goes to sleep.

Is Ambient Display not working in this ROM?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
A search yields multiple mentions that it's turned off because of massive battery drain. V20 doesn't have an OLED screen, to power just the pixels that are active we still need the whole screen powered on.

This also causes burn in.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Grin59:
It is working just not the always on display. It'll turn on when you pick up the phone, wave at it, and get a notification. You would not want it always being on since the V20 has an LCD screen and not OLED meaning the entire screen will be on.

Even we had an OLED screen, why would you want the screen in when you're not looking at it? It'd also be causing burn in eventually too.

Although if you really want it to work, go try out Resurrection Remix. It has more features and is more up to date than Lineage. It's my daily rom now
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] zhangla:
I am just curious if IPS screen is so battery draining, why the 2nd screen is on 24/7 with the stock ROM yet it does not really impact the battery life much? I don't think the 2nd scree is OLED
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] zhangla:
I cannot get the screen to show anything no matter what I do, except to press power button or double tap. Once the phone goes to sleep, it's dark even if there is incoming text or other notifications.

If the error message was different, then this won't fix the issue.

Are there any variants of the V20 which lack /firmware? To the knowledge of people I've asked all V20s have /firmware, and it was only the G5 which lacked /firmware. I'm trying to get a commit done which assumes all V20s have /firmware and will break devices if the belief is incorrect...

The latest fully working version is 15.1-20180808. After that the bugs we experience are introduced. This is the only version that can be used as daily driver. Remeber that many vulnerabilites were found after this release. So the phone is working as intended but not secure.

I have a H990DS.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
Not sure what problems you're having, but I'm not having any issues at all and have been running builds past that date since the day they came out, as daily drivers.

That leads me to believe it's something to do with your setup specifically.

Everyone has different software setup but I don't have a single issue.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
Is there anyway you can give more details than it has a 15 second delay?

Unlock your phone and try to increase or decrease the volume. If nothing happens and the slider appears after a delay, you have the previously mentioned bug with the timeout on the audio device as shown in the logcat.

This problem has many symptoms. For example you can have the locking issue which was mentioned multiple times already. Or you have problems to accepts calls or even make calls at all. The guy you just quoted has this problem, too.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] scorpio76r:
Hello, quick question... Is this the only option that we have if we are to keep this phone? Seems stock is no longer an option. Am I correct? I also read online that you were the first member to notice what lg did and, you pointed it out to the rest of us, thank you for your heads up.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
It was sad news, but still, you're welcome.

I didn't move to this ROM recently; I've been running LOS for quite some time now, probably between 6-9 months if I had to approximate.

Custom ROMs are indeed now the only option if you want a V20/G5 that's as up-to-date as possible. Now that official stock support has been phased out, if anything, custom ROMs are now more important than they've ever been.

I think this will be a good thing though. As more users look to custom ROMs like LineageOS for features, security, updates and efficiency, people are going to also end up getting more life out of their V20 than they otherwise would have (because of the much cleaner, faster and more fluid experience it provides vs stock).

With LineageOS 16 beta available for Android 9, a full major version above the latest available stock update, and the aforementioned more fluid, clean, faster experience it provides, I don't really see a reason not to be running it.

LineageOS 15.1 has been stable for me for as long as I can remember, and has gotten me through work life, personal life and everything in-between.

The DAC works in either 15.1 or 16.0, as does the second screen (it works natively in 16.0 courtesy of Pie's native 'notch' support but on Android 8.1/LOS 15.1 requires a second-screen version of a ROM like ResurrectionRemix with a custom framework implemented), there's custom kernels available, and ways to deal with the burn-in issues that plague stock among all the other great things a custom ROM beings to the V20.

I've never been left in a situation where something critical has left me with an unusable device, especially since I always have a TWRP backup on my microSD card ready to go.

Stock IS an option if (for some reason) you want to keep the stock experience but you forgo important security updates, optimisations, etc.

It's still important to keep stock-related things for those that ever need to restore to stock, and it's important we have mirrors of all the files and processes important to the V20 (KDZs needed to obtain root, DirtySanta files, etc.) and I've been meaning to put together some sort of a repository for everything for a while now.

The only challenge I see us facing is support for Android versions above 9.1/Pie and beyond, but no-one really knows what's happening there (Google's FuchsiaOS is rumoured to take over from Android at that point, but who knows).

In short, I don't think there's ever been a better time to ditch stock and join the custom ROM community. We all know how trash LGs software support of their devices is, but we should be thankful we're fortunate enough to have a device with the possibilities that the V20 has.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] scorpio76r:
Thank you so much for this. I'm also guessing that there will definitely be more subscribers to this there. I just subscribed.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Electrolite_XYZ:
I can't give you my baseband because I left Lineage and a new ROM changes the baseband right? (I'm a noob correct if I'm wrong).

My model was the H990DS, not sure if you can infer the baseband but I flashed Lineage directly from a old stock Nougat (used to root) and was using Gamma kernel non ss v60.

Until the end I was having issues with random slow downs, long time to shutdown/restart after pressing the option, volume taking time to change when pressed, phone not locking when I press the button (when I woke it wasn't locked it was in the app I was using and I could use it normally) and other generic slown downs and freezes, but they were rare and random.

But my main issue with LOS is that the DAC isn't working properly (yes I know the DAC works otherwise there would be no sound) but I'm pretty sure that the high impedance mode isn't engaging properly, my high-impedance headphone presented all the symptoms of not being driver properly with amplification while using LOS (unlike on stock ROMs).

I'm using the flashable stock Oreo now and it's much louder and sounds tighter (being driven with more power), when I turn off the high impedance mode DAC with that button it sounds just like it sounded in Lienage, same volume and same flawn in sound because lack of amplification so I'm pretty sure LOS isn't using the amplifier properly or can't trigger that action when a high impedance headphone is connected.

Lineage is by far my favorite Rom and I miss it, Lienage 16 is also looking gorgeous but the audio issue and the lagging issues forced me out.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] scorpio76r:
Hey guys, I'm just joining so excuse me for what might seem like a idiot question. Can someone please help me identify the latest 15.1 or send me a link? I can't find the H918 15.1 Los rom in Google drive folder. (I'm coming from stock on the H918). I have never used Los before and, I'm grateful that this is a way to save the v20 after what LG did to us recently. Edit * (I found it).
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
Your baseband version is determined by what version KDZ your modem is from, and what region. I've seen different region V20s running stock with different baseband versions while on the same software version.

In order to update your modem, I believe you have to manually flash the modem partition from an updated KDZ using KDZWriter, which can be done even if you're on a custom ROM.

You can't currently use 20a's modem though, emdroidle said it causes crashes.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ESmazter:
I flashed the using the KDZ file H990ds10k_00_OPEN_ESA_DS_OP_0117.kdz (https://lg-firmwares.com/lg-h990ds-firmwares/#tab=firmwares) and kdzwriter with the command:

kdzwriter -m H990ds10k_00_OPEN_ESA_DS_OP
_0117.kdz

Now I have Baseband: .2.0.1.c3-00045-M8996FAAAANAZM-1

And guess what. It seems to work now without the lag. Thank you very much for the hint [MENTION=5988026]Redline[/MENTION] !

It would be nice, if someone is able to create a flashable modem from this file so that the other guys can do it without having to download the large kdz file.

Can we please add this information to the first post [MENTION=2881807]x86cpu[/MENTION] ?

[MENTION=8921470]Electrolite_XYZ[/MENTION] give it a try!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
You aren't able to create a flashable modem zip, because not only are KDZs laid out in a weird format (I wouldn't even know where to start to extract just the /modem data) but every variant more than likely has a different modem version, that's different again for each version of software for said variants.

We'd be looking at well over 20+ different flashables across every variant and its software versions. It makes sense to just have people download the ~2GB KDZs and flash them using that.

They're useful to have for returning to stock anyway, it's why I still have my stock KDZs.

I'm glad that ended up solving it though! I suspected it was something to do with the modem since that's the only difference between me not having that issue and other people having it.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Electrolite_XYZ:
So I just flash the modem from the latest nougat kdz I I can find? Different regions aren't an issue and I can do this while already on Los 15.1?

Well makes sense that my issue was an old modem, I flashed Los over a very old stock kdz, at the time I thought Los would update everything so I didn't need to worry, now I wonder if my bad mobile data range and connectivity is related to this old kdz.

Unfortunately I don't plan to do this now, I just flashed the stock Oreo, I would need to wipe everything again and hope that my TWRP backup would be able to restore the Nougat bootststack and my fingerprint with it, also there is the high-impedance issue which is a deal breaker for me.

But eventually I'll have to go back since the V20 updates are dead, I already miss the bloat free and better battery of Los and if the audio is ever fixed I'll come back running.

Hey guys. I don't want to sound like a noob here, but I have been reading for hours and I want to safely install Lineage 15.1 onto my H91810J device. I wasn't sure if I should follow the guide to upgrade to ARB1 H91810P first with a KDZ flash, before unlocking bootloader/rooting/installing twrp etc. Am I lucky I am still on H91810J? or does it not even matter?

If you are completely stock then you can use the regular LG up to flash 10p, FYI once you flash 10p arb will be incremented, so you can no longer downgrade prior to 10p.
