I see.. Been read some people posts about camera issues, seems it will be focused when LineageOS 20 ready.

Video play slightly lag in MX Player both HW+ and SW. Sometimes video in Instagram feeds not loading and also slightly lag, not frequently though. Honestly it's not big deal for me. My main concern just battery life, DAC, and basic communication and internet function.

This LineageOS far better than stock oreo. I'm really enjoy using this ROM :)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
I had never tried before recording at 60 fps on Lineage, but I remember that I tried on stock Nougat and worked. At least on Lineage 19 with GCam it locks at 30FPS (without sound), with Open Camera again at 30 FPS max, but I could reduce to 24 FPS just changing in the settings.

I use mpv and works just fine with all my library of 1080p BD-Rip and web-dl on either x264 and x265 (just remember that multi-channel audio has volume controls still broken, not only on mpv but stock player as well) and I play directly from my NAS. I never tried any video above 1080p on this device.

Another BCL tweak has been pushed, next LOS build should, theoretically, behave better in regards to random reboots.

Also, it cannot be improved further unfortunately, so if you still have random reboots only on LOS 19.1 (as in, stock and LOS 18.1 work fine), it's because your model or battery is triggering some issue in the kernel where the lge code on the older kernel worked around it somehow, and it's pretty much impossible to transplant it into this newer kernel.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] AShiningRay:
Not only the kernel. Our rom-side camera blobs are awfully out of date, and with them being closed-source, there's not much that can be done on them besides hexedits.

There was an attempt to port the whole camera setup to OSS hals a while ago, but suffice to say, it hasn't progressed much yet and maybe won't at all because it's very complicated to do and cam sensors aren't even picked up with OSS yet.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ElMichi:
hi, i have LG V20 h910, unlocked with little santa, i'm not a newbie in lineage roms, but i've never been able to get lineage OS working on this device, or any other rom, i tried to figure it out by myself, but i never could achieve it, someone here would give me a hand?

the device is not broken, I flash any rom, crdroid or lineage and it doesn't boot, it stays in the boot animation forever until it reboots, I flashed the roms with recovery twrp and with the lineage one and nothing, then I flashed one android 7 rom and it runs perfectly xddd

I do not know what else to do.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] AShiningRay:
Huh, that's a rare one. So it loops for a while and then reboots after some time? If so, you might be able to get the ramoops file (basically a log of what has been happening until it crashed) by booting directly into recovery when it triggers a reboot.

Quick steps:

1 - Try booting normally and keep an eye on the phone

2 - Once its screen goes black, that's when you need to use the button combo to get into recovery

3 - Once in there, no matter if you are on TWRP or LOS Recovery, enable ADB and link the phone to your pc

4 - On a console or terminal (assuming you have adb installed), run adb shell

5 - Run ls /sys/fs/pstore/, and if there's a console-ramoops-0 file, run cat /sys/fs/pstore/console-ramoops-0 to see its contents.

6 - We won't need the whole file, so you can copy the last 500 lines or something and send a small file here so we can take a look at what's failing.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] 0ldsoul:
I see. Thanks. I always manually update mine. I don't use OTA in fear of downloading corrupted files. I usually update shown on the site. I'm just making sure I'm not doing more steps than needed. :)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
You are - use the Updater app - it does more sanity checks that just updating via recovery - corrupted updates aren't a thing - it will fail before it installs if you manage to do that somehow.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ElMichi:
i did such procedure but it seems that such file does not exist.

the first command didn't give me anything, and the second was, "inaccessible or not found"

Should I run it with the mobile with the lineage ROM? or it works the same when running these commands from android 7
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] AShiningRay:
adb shell won't give you anything right off the bat, it'll just "log" into the phone (you can see that if your terminal's cursor working directory changes to "elsa" or something that resembles the V20's model numbers)... But if the "ls" command failed, that means you either didn't get the shell to work (make sure you enable ADB on your recovery and ADB is also installed on your PC), or you're running an android and kernel version that don't have ramoops enabled.

And yes, you should run those commands after failing to boot at least once in LOS 19, after which you'll need to go directly into the recovery to read the ramoops right away, otherwise it will be flushed in the next boot.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ElMichi:
Ya hice el procedimiento y el archivo "console-ramoops" no aparece en la lista despues del primer comando, entré en modo fastboot y mi variante es msm8996, (no se si este dato se puede cambiar dependiendo del recovery que está instalado) suponga que compra la versión h910 de at&t, el "estado de búsqueda" dice buscar.

cargue un TWRP para h910 e instale el LOS para h910, hice el mismo procedimiento pero esta vez para us996 y tampoco aparece el archivo "console-ramoops", use el método little santa para acceder al fastboot, no sé que problema tienes o como solucionarlo que pasa a partir de ahora?

Le agradezco que se tome el tiempo para responderme.

As a rule of thumb: Unless in a forum have a specific non-English section, you should always use English. Even use many translate tools available to do it. Some places are more strict than others, but that's the rule.

As your question, I don't have the low-level knowledge of the devs here, and so far on the devices that I owned throughout the years dealing with Android never had a single issue with TWRP (unless I was trying to flash some super new ROM that requires a newer version of TWRP, so update and flash again... But maybe I got lucky?)

With the H990DS the only time that I had any problems flashing any ROM was with the Lighthouse Raft but flashing an older version of TWRP solved my problems. Other ROM was DivestOS, but even with their own recovery I never got it to properly boot (I don't know if it was a problem trying to encrypt the data or anything else before first boot)

But as I see around here and as another unspoken rule: If the project officially support their own recovery, it should be used, or face the consequences.

You mention that you have the h910 and flashed both the us996 and h910 TWRP recovery, so I must assume that you cross-flashed taking the necessary precautions and unlocked properly.

I don't like the Lineage Recovery for my own personal reasons because I don't like to be tethered on my computer as on TWRP I can perform more tasks without needing my computer... But Lineage Recovery it's the only who could format properly as the TWRP appeared success, but the device failed to boot after flashing.

The latest time that I formatted my device using TWRP to clean flash TWRP it apparently worked, but it never could get to the first screen of welcome. So I used Lineage Recovery, erased, formatted and everything possible and after that used to flash the OS itself. Worked flawlessly.

So do you try the Lineage recovery a chance using properly?

As far as I know all V20 variants use Snapdragon 820 (MSM8996)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] AShiningRay:
Do not enter fastboot, you should be entering recovery instead, with that being either TWRP or LOS Recovery. You have to enter it with the button combo right after the phone's screen turns black after being stuck on Lineage's boot animation for a while.

You said you installed TWRP after (apparently) using dirtySanta to unlock your phone... but did you update it? The version commonly installed with dirtysanta is really old and TWRP 3.7.0 is the bare minimum you'll need to reliably install LOS 19.1, newer is better. Either that, or LOS Recovery's latest builds.

The vast majority of them do, yes... although there are a few sporting a Snapdragon 821 here and there. In any case, it shouldn't matter for ADB because those same commands can be run on G5 and G6 as well, and recovery won't change your SoC's internal name.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ElMichi:
I'm sorry, I sent my message in English, but before sending it I translated it with the browser's tool to verify that it was correct and then I sent it. xd

I have installed LOS with the twrp revovery and with the recovery lineage and I get the same result, it never boots, the phone is not damaged because I have installed a rom with android 8 without lineage and I have it working right now, I have done the procedure with the latest versions of lineage and twrp recovery, and nothing.

Who should I go to for guidance in order to run LOS on this mobile?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ElMichi:
Yes, I have installed the latest version of twrp and recovery lineage from their respective websites, LOS is also from the official website, I clean the data before doing the procedure as in any other device, I do the procedure and when I start the phone, it never happens from the boot animation of the lineage.

It is not the first time that I put a rom lineage on a mobile, only this time I do everything as it should be but it does not work xDDD
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
Like I said, it's my experience with my H990DS that I'm basing what I think maybe useful to you case as well.

In TWRP it may appear that everything it's correct and functional, the wipe, format and the flashing process. The first versions of LOS 19 when it was available worked for me, but not in the last time that I flashed the device.

And sometimes just "clear the data" may not be enough, I mean really format at the point that every folder when you see trough MTP it's gone, nothing literally.

I'm not saying that you don't know what you are doing, and maybe you really have an odd device. I'm just trying to make things clear to help you with the limits of my knowledge/experience.

For diagnostic purposes(with available time from your part), you should try other non stock ROM's and see if your device complete the boot process after a clean flash, and from there you can make more accurate assertions.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
I would love to get one if they can be easily available. But in my experience with the OP3(non T) and the Pixel XL that have the Snapdragon 821 I couldn't see so much difference, but still the power consumption/thermals worries me.

Or simply board swap since this device it's much more friendly to maintenance.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] AShiningRay:
Wait... so it doesn't even reach the boot animation, or does it reach, but never leaves it (not even by automatically rebooting after a while)?

Cause if it doesn't even reboot, or reboots before reaching lineage's boot animation, you won't get any ramoops unfortunately.

Hi, I cannot get the phone to either receive or sending files through NFC android beam. Sometines it restart the phone sometimes it just doesnt do anything. I attach the log. Hopefully it can be fixed. Thanks
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] bobminshull:
Just wanted to jump in and share my gratitude. Incredible work and I will be donating asap. I haven't had a single issue short of I keep losing magisk root seemingly randomly. Haven't read through the thread yet so I'm sure the answer is in here somewhere. I'm sure it's just user error. Regardless thanks to everyone that contributed.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ElMichi:
I install LOS and the OS never starts, it stays in the lineage boot animation, after spending a while in the animation it restarts, that's how it always happens, I installed LOS in its previous versions and nothing, to date they don't work, and I don't have idea how to solve it xD
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] AShiningRay:
And you can't get ramoops by hijacking that restart by going straight into recovery? Yeah then i've no idea what's causing that... maybe wrong firmware or something along those lines, but even that's unlikely.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ElMichi:
so i can stop the lineage starting course after a while of being in the boot animation, take out the battery and then enter recovery to recover the ramoops file?

Before trying that I want to make a copy of my data, but not with twrp, since last time it didn't make the copy for some reason it gave me an error, I want to find out if I can do the whole copy process through adb, and then the LOS installation by adb too, let's see what happens, regards.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] AShiningRay:
No, ramoops stays on the ram, so removing the battery will erase that data... what you should really do is wait for the phone to reboot after being stuck on the boot animation for a while, use the button combo to access the "factory reset" menu (which actually takes you to recovery), and then get into your recovery of choice without powering the phone off at all.

As for backing up your data, if you only need to backup internal storage, you should be able to use the 'cp' command on adb shell to copy all of it into your PC, as it's all located in /sdcard.

Is it just me or is it software related? When I make a call, the proximity sensor works, so it blanks the screen when i put it onto my ear. But when i take it away, it doesn't light up the screen again

Yes, but you need to setup your password, pin, pattern so you can latter setup the fingerprint unlock.

I would appreciate some clarifications on which LOS build to use for the H990DS variant? I'm guessing it's the H990 build here? Am I good if I follow the steps for the H990 variant? Mostly worried about the Dual Sim feature & QuickRemote (IR Blaster). My H990DS is on stock Android 7.

ALSO: is the 2nd screen supported with LOS?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
Well, I have an H990DS as well.... Welcome.

But, may I suggest next time to spend a little more time to search? Because all your questions are already answered... And yes, all works, but the second screen isn't the exact original functionality of the stock ROM, it would behave like an extension of the main screen.

So if you didn't already unlocked your bootloader, it's the first thing to do, and in this forum have a great thread with lots of valuable information and instructions to help you achieve that.

So take your time and read, make notes, download and follow the instructions that I'm sure that all will go well.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Xfoliate:
Thanks for the reply, I actually found some answers after my post with a little more searching with regards to the IR Blaster. Looks like it should be working just fine.

But I can safely say that I didn't see any confirmation anywhere mentioning the exact LOS build to use with the H990DS. And I didn't find any specific mention of whether or not the dual sim feature will still work. I might have missed it?

I also saw that there is a way to get near stock second screen functionality with "Resurrection Remix" Custom ROM (which I'm not familiar with at all) so I'm wondering if something like that is possible with LOS instead of extending the screen?

I'll keep searching but I'd appreciate your help since you also have the H990DS. I'll even buy you pizza.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
As you could be aware there's at least 3 variants of 990: the Single sim H990, the dual sim H990DS and the Chinese H990N. And as far as I know the developers included all necessary changes to work between the different variants.

I'm happy that my V20 H990DS has dual sim and it works flawlessly, data, calls and everything that I tried so far.

But not everything it's paradise so far... Let me make a list of things that not exactly works or have some limitations:

1) Double tap to wake: Works flawlessly if there's an app that its currently keeping the device active, like playing some podcast/music or on a phone call. Works as well when the device are plugged or charging, otherwise may not work as consistently (on the stock rom for me wasn't perfect either)

2) FM Radio: It was available the app on the first iterations of the Lineage builds, but didn't work and at least on my device on latter releases it's completely missing, but since I don't listen to radio doesn't bothers me.

3) Sound recording: The levels of the mic(s) are a little low for my taste and the last time that I checked was recording only in mono, but this is a problem that the devs are aware and will be fixed with more time+testing.

4) Multi-channel audio playback on videos: The audio it's played normally, but you don't have control of the playback volume. Also this was discussed and will be fixed in the future.

5) USB hub features: using your phone as a modem and or HDMI out (Im not 100% sure about this) isn't working at this moment, but transferring files with MTP, PTP it's working perfectly.

6) Bluetooth and NFC: There's some complains about some things not working 100% but the results are mixed. I tested with an Bluetooth Keyboard myself and an remote camera shutter button with 0 bugs. Never used NFC on this device, but other users reported success cases.

7) Camera: The stock Lineage app in the launch wasn't perfect but there's a lot of options of GCam and others that can get a really good photos. On recording videos I didn't have audio on the GCam version that I'm using, but I'm lazy and with no real necessity of searching other version at the moment, but the stock camera works fine for that. And the Hi-fi multi fancy audio from stock rom I believe isn't implemented because proprietary blobs and other shenanigans from LG

Could be implemented? Probably, but the project it's Lineage and they have more strict guidelines to make more concise overall experience across different devices. So it's less likely that this feature could be implemented, but never lose hope.

I'm flattered with the offer, but the devs... They deserve much more credits/incentives/donation than me. So if you are happy, let them know.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Xfoliate:
Thanks for clarifications. I will probably be up and running by tomorrow. I'm just gonna read through the steps few more times and let it soak in overnight.

With regards to the second screen functionality, I will definitely miss it. It's one of the reasons why you'd want this phone. But there's an app called "V30 floating bar" that kind of gives you the same things but it's still just a floating bar only when your screen is on. So you don't get the AOD features.

And yes, the devs deserve all the love here. All the pizzas. I will try to donate to the V20 LOS devs.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Xfoliate:
On my H990DS, just noticed I don't have any VOLTE option in the settings to turn on and can confirm that VOLTE is not working for me at all. In the LOS installation steps, it says to make sure to use VOLTE at least once on stock android 7 before installing LOS.

From what i can see, LOS doesnt support VOLTE but im just wondering why its missing for me? Is it just missing in android 7?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
Same here, and on that matter isn't a problem unless you have an carrier that is restricting coverage/operations for non voLTE users as I believe in USA/Canada (I don't know if there's more cases like that).

In my country most carriers have voLTE, but on Android 7 and 8 I didn't have any voLTE support probably because my V20 variant or V20 in general was never certified or anything in between (even on my OnePlus 3 I had to make many adjustments/flash and many more, just to enable and in my carrier wasn't a game change)

So with Lineage on the V20 in general voLTE isn't supported because the way it was implemented in a proprietary way by LG (Samsung and other manufactures have the same bad behavior) and it's challenging or almost impossible/impractical to reverse-engineer it.

So if you don't miss and/or need voLTE, no problems for you.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Xfoliate:
Not having VOLTE on its own is not a HUGE dealbreaker but it's definitely nice to have. But what you just mentioned about coverage/restrictions with some carriers is a dealbreaker. I was planning to use this phone as my travel phone especially with the dual sim.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
LineageOS itself supports voice over LTE just fine, it's just this device family that can't support it, LG devices in general really can't support it on custom ROM
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] loyukfai:
With regard to D2TW, it's to me a regression because it worked flawlessly on LOS 18. However, the benefits LOS 19 brings far outweigh the ability to reliably utilize D2TW for me.

The camera can be a deal breaker for some, but my usage of V20 doesn't demand it, but yes it would be nice to have it works more reliably.

Cheers.
