So I just upgraded my h990N from LOS15 unofficial, to 16 unofficial, to 17.1 unofficial,

then flashed twrp-3.4.0.1, official-to-unofficial.zip, los 17.1-20200809, gapps arm64-10.0 20200808, stock-thermal-engine-mod, gamma kernel, Magisk.

As mentioned camera starts working after another reboot.

However I couldn't get bluetooth calling to work. It's not even low volume, just nothing on both ends. Bluetooth audio works.

Also the phone would freeze a few times and only taking out the battery would restart it. I disabled trust agents and will see how that works out.

LiveDisplay -> Color calibration -> all colors to 90 resolved the problem with ghost images.

Increasing the mic volume levels in mixer_paths_tasha.xml worked fine

Overall it feels much faster, great thanks to all colaborators.

Yes bluetooth calling(BT devices 4.0+) is not working in 17.1 for many folks including myself. I am using H918. the forum and lineage bug tracker has reports of the issue. It works fine with 16.0

Just installed the New August Nightly Build on my V20 H990DS

Encountered issues:

•Unable to unlock phone fingerprint and on-screen unlock (keys won't pop up)

•Random reboot on the first 5 minutes

•Freezes on bootscreen logo

•When using camera stock/gcam photos are not saved/displayed in gallery.

Edit

•No Audio on Video recording. Recorded videos appear when rebooting but no photos.

Flashed lybxlpsv's BETA 2 Gaming OC Kernel for LOS seems to fixed random reboot and freeze on bootscreen.

Just need to know if anyone encounters the same issue with the camera/gallery and how to fix it.

[LG V20 Guides, News, & Discussion] pradeeppk:
Does partial LGUP cause sensor to stop working? when i flashed LOS 17.1 on rooted oreo base all sensors and camera working properly except fingerprint. Then tried to flashed Nougat kdz using LGUP using partial dl feature, omitted recovery, recovery.back, aboot, aboot.bak. Again flashed LOS17.1 at this time fingerprint works, but all other sensors and camera stopped.

Then flashed RR 6, all sensors and Camera working, flashed RR 7, all sensors and camera are working properly.

Any suggestion?

Hi.

I have an US996 USA ver. and I clean installed the latest nightly 20/8/6 coming from the stock 10p and every thing works fine e.g: camera, battery life, speakers, preformance, thermals, Wi-Fi, Bluetooth, hotspot, mobile data, fingerprint, etc...

The only big problems are:

-the Sim card (CDMA) gets disconnected randomly and I have to reboot to get it working again, but sometime rebooting once doesn't fix the problem ( I have to reboot multiple times ) and it just shows ( No Sim card ) in lock screen stats bar.

-The static at boot is still present and I couldn't find a stable kernal to fix ( If anyone know about one, please share it. ).

Other than that, a good experience overall.
[LG V20 Guides, News, & Discussion] Vortell:
Not sure whats going... If it works on los 15.1 it has always worked on 17.1 except for a short time when clean install woukd cause issues. Seems to be type where if you close all the cameras and system resources it would work again. Not sure why. Never use camera but it does work. Just have to reset it one way or another. I know dirty flashing from Los 14.1 eventually failed and I had to do clean install for 17.1 before that it was the only way to get it to work. The other thing is if you have TWRP most the time the flashable file from i98 can solve most firmware issues. So you could try that for sure.

We all know lineage and lg phones do not play nice when it comes to volte, and without security updates our phones will be paperweights soon https://www.lg.com/us/support/email-to-president Please leave some feedback there and maybe we can change this on future LG devices.
[LG V20 Guides, News, & Discussion] cnjax:
Volte works on stock based roms
[LG V20 Guides, News, & Discussion] TripOG:
yes, old roms without security or os updates, if we wanted those we probably wouldn't be commenting on an xda lineageos thread.

sorry, if that comes off like a ****, I just had a conversation earlier where the person was standing up for LG for not releasing updates and making volte a pain to enable in aosp roms. I guess some people think it is acceptable to abandon flagship phones.
[LG V20 Guides, News, & Discussion] cnjax:
That's the problem with lineage its half baked at best, most of the stand out features of the v20 will never work on Lineage, but I'll take stock based over lineage any day even without security updates. If you are prudent about what you put on your phone then you won't have any issues, I haven't had any. But alas the v20 is a dated device, so if you want a full functioning phone with the latest and greatest OS and security patchs best to get a new phone. Heck Google is getting ready to release the 4a for 350 and from the reviews I read it's a great phone for the money and you'll get 3 years of updates.
[LG V20 Guides, News, & Discussion] TripOG:
I see that as problem with LG and this phone, we shouldn't have to choose between security/software updates and features. I would like to be able to use my device as a phone and still receive updates. Right now, lineageos is the only way to do that, until next year when a lot of these phones become paperweights. If you don't care about updates, and only care about gimmicks that came with the phone then yes you are fine until some security flaw bites you in the ass. Either way the support LG provides with phones is awful and that alone is worth the time to send them a message in hopes they get their **** together and not considering them for a new device until they do.

fwiw i have an old ass windowsphone that is running a more recent os than available to my v20 from lg and it has volte. LG should be embarrassed of their phones.
[LG V20 Guides, News, & Discussion] MaverickNextDoor:
What's happening next year to make them paperweights?
[LG V20 Guides, News, & Discussion] eaburger:
I cannot be more agree with you! I use the link you proved to give them a complain about the lack of post sale Software support, I'm aware the 2 year support that most of the company give and right know they are seeing is so bad that they are adding more time (cough "Samsung") considering other give since start more software and security patches for more time (Google, Nokia, Motorola,m Sony, Oneplus, etc).

But as was mentioned before way 4 years ago, last year, or tomorrow if a paid for a flagship mobile (no less that 800$ in his base model, not considering the Ultra, Pro, + o what ever over priced version :rolleyes:) they will give me so bad support as LG give it to us, for that reason my next mobile surely will not be a LG, and of course I give all mi thanks for this community to continue giving more live to our old mobiles and also are the best proof that the problem is not a old hardware (or have the best hardware, the thing they want us to purchase) is the software and the support you give to that hardware!

Long live to LOS and XDA! ;)
[LG V20 Guides, News, & Discussion] TripOG:
most networks are shutting down 3g service so without volte you will not be able to place phone calls. Some stock roms have volte so if you don't mind older android versions with old security patches you can roll back and still use your device. If you want to continue using lineage you will not be able to place phone calls. If you want volte and current android patches you will need to buy a new phone.

coming from stock 20h following the forced downgrade to 10p to actually be a able to bootloader crack and install recoveries with recommended toolkits...

i've tried official twrp-3.4.0-1-h918, Phoenix591 twrp-3.3.1-1-h918--2019-10-25, and LOS Q 20200813 rom (finally switching to los recovery, wiping system and cache to reinstall los, opengapps, magisk, leaving data untouched), but...

rtc resets to build date on every reboot or power down, and i need to connect to the network to correct the clock date time info.

i don't see other people mentioning this bug, so i don't know if people just don't care enough about it to complain, considering all the other issues and hassles trying to make this device ready for non-stock.
[LG V20 Guides, News, & Discussion] rlvddoes@gmail.com:

LG h918

Fix

Clean Install RR 7.02 and reboot

Set date and time and reboot to recovery

Dirty Flash LOS 17.1

Hope it works for u.
[LG V20 Guides, News, & Discussion] jmichael2497:
actually i just re-did kdz to 10p, lafsploit, final phoenix591 recovery, los 20200813 with opengapps 202007xx, and it seemed fine...

so i made twrp data only backup, restored my fully configured twrp data backup, but time was broken again.

so i restored twrp data backup, since obviously that should fix it, right? nope.

this is all so frustratingly poorly documented, so i tried all sorts of factory reset, format data system cache, flash with los recovery as well and only the los rom no gapps, then camera app stopped showing and working.

maybe because i'm using 10u modem with 10p bootloader this is what happens, so i just re-did kdz 10p and will try again another weekend when i have time to waste reconfiguring every little f-ing setting all over again, sigh.

(i hope this s5 running los 9 p doesn't get any more finicky in the meantime)

[LG V20 Guides, News, & Discussion] Wilro1999:
Howdy All,

Just signed up with xda (been lurking since the Samsung Galaxy S2 days ;) - I currently have a H910 & H990N V20, & noticed that both of them suffer from this rtc issue (never really noticed before, as they rarely get rebooted/powered off) - The above post gave me a clue as to what I suspected is the cause - selinux permissions in my case.

I have resolved this issue for both of my phones (one I use simless & the other runs dual sims) - Both are running the latest los 17.1 (Aug 2020 security level)

Flash Permissiver_v4.zip (search thread to find a link - grabbed it ages ago)

Boot device like normal

Go into settings->system->advanced->date & time

*disable* Use network provided time

turn off all network connectivity (wifi/mobile)

power off

power on

re-enable network connectivity

Voila!

While I prefer not to disable selinux, having the phone rollback time/date causes a lot more issues for my apps that start during boot before network connectivity is established

Hope this helps!

Standard disclaimer: "It works for me" :fingers-crossed:
[LG V20 Guides, News, & Discussion] jmichael2497:
i did notice a lot of threads mention changing selinux to permissive mode for various other reasons i didn't really look at, but i want to avoid that if at all possible, so i'm going to wait and try the next build since this one seemed really weird, even after data format the camera app was hidden and would crash if i tried to force it to start.

(although i'm tempted to go looking for the official maintainer's now "unoffficial" pie to see if that works better (being closer to the blobs).
[LG V20 Guides, News, & Discussion] Wilro1999:
Yes, there is a lot of reasons to try it - It's probably the easiest way to prove if it's an access permission problem after update - Worse case scenerio is you re-flash the same version of los & it's re-enabled.

I had to do this on both my devices at some stage (was always getting the 2 out of 3 working sensors - Camera/fp/Torch) - Done it once on each device (up until now ;) & have never had to go back to permissive mode. ( I don't know how long this rtc issue has been happening for me, as it wasn't I looked/tested for after each update - it will be now ;)

I was thinking of going back to enabled to see if it was just a one off again, but then, we are due for another weekly build shortly, so I'll probably just leave it as is until then.

[LG V20 Guides, News, & Discussion] jailedmike:
I have an issue with streaming video using .mp4. I'm primarily using it for upnp. I have tried money media, bubble upnp,vlc and nova video. For Simplicity I just use VLC take a log of what happens. Oh yeah it takes about 10 minutes for it to happen. It work fine if I download them to local storage. So I assume this is caused by some network buffer. Wish it would let me upload a log. I will try again later. I have tested to for out server side issues or network issues. As it works fine on at least 5 other Android devices. It you need upnp server to test serviio is free. Was may different codecs as well just to for it out. I am on official do use magisk and was clean install.

Hopefully this link works.

[LG V20 Guides, News, & Discussion] ssurell:
Charging loop

us996 ran down battery and device shut off. Now when I plug it in to charge, it begins to charge and see the empty battery image with the dotted circle, but immediately tries to start the bootloader, dies again, goes back to the charge screen, and continues this cycle without ever charging. Plugged it in overnight and was looping in the morning. Pulled battery, went into fast boot, almost went into TWRP but died at splash screen. Can't seem to get it out of the loop. I can use a special external battery charger on it, but there is an obvious bug with the kernel. This is the only phone I've had that didn't emergency power cycle with long pressing power button. ima plug it to a PD charger when I get home, and give it more to deal with.

update: So PD charger gives it the extra juice to cycle completely through the bootloader splash screen and then returns to a slightly different charging screen with a smaller white battery image that indicates the level of charge. Apparently, the 500 milliamp laptop and 1 amp wall charger didn't have enough capacity to get it into a proper charge mode.

[LG V20 Guides, News, & Discussion] eaburger:
In TWRP (Restart it and enter in the Recovery) follow the next Steps:

Press the "Install" option.

Press "Select Storage" option.

Select "Internal Storage".

Up until you are in the root folder "/".

Select the "data folder "/data".

Select the folder lineageos_updates "/data/lineageos_updates".

Select the .zip of the last update package of the OS you downloaded by the date (remember in the package the date is YYYYMMDD), my recommendation to avoid using a lot of memory and have this easy to select that previously in the Update option you deleted the older packages.

OPTIONAL: If you have other .zip to install select all of it (yo will need to go to the folder where you have all of this saved), my investigation took that the recommended order is OS update, Vulcan and OpenGL drivers, Kernel and his packages, Magisk (this is updated with the LOS update, but if you change the kernel you need to install it again) and lastly GApps (if you are in the first install or update Gapps via TWRP).

Run the installation process, remember that depending of the quantity of .zip will take more time.

when the installation ends and before restarting to System, do a Cache Wipe (Dalvik & Cache), only to ensure the cache of the apps is regenerated with the new version and avoid any possible problem.

And for last wait until the OS bot up and finish all the update, to perform the "almost" mandatory phone restart to gain access to all the sensors (camera, and others).

I always use this method to install in the same process the updated Vulcan and OpenGL drivers, Gamma Kernel (with Tasha and Thermal) and Magisk at the same install process and do not need to go to TWRP after the LOS Update.

I've hacked up a kernel that attempts to fix intermittent broken camera/sensor issue by bypassing sensors related selinux denials, especially if you came from stock pie or oreo.

Gamma only for now. may attempt it on LOS stock later.

Only tested on H990DS so DWYOR.

Details for security concerned ppl :

for some reason u0:r:sensors:s0 got blocked trying to accessing u0:r:sensors:s0. so when it happens it got bypassed.

to double check you can run

dmesg | grep LYB

and then you will see

Are most people here using this ROM on their primary phone? or on a secondary testing device? I use stock 8.0 on a H910, and it's getting a little outdated. Applying new thermal paste on the processor helped a bit; making the phone run a little smoother, but nothing like CyanogenMod on my Nexus 6 back in the day.

I typically test the ROMs myself without asking someone to do it for me, but I'm unable to test this ROM extensively right now as my H910 is my main phone; based on your experiences, is this ROM good enough to be used on a primary phone?
[LG V20 Guides, News, & Discussion] aCIDsLAM:
Depends, what you need. LOS 16 on primary h918, Los 17.1 und Test Phone, as long as TWRP cant decrypt Data on LOS17. 1

If that Problem wouldnt be, i would use it on the primary
[LG V20 Guides, News, & Discussion] Merazomo:
Now that I think about it, I've never encrypted a phone as I always flash the ROM/Kernel and start using the phone right away; big mistake on my part, but I've never lost one either. Is that the biggest issue you've noticed so far on 17.1? Since I've never done it, I shouldn't worry about decryption right? I mostly care about: Wifi, LTE Data, and the Camera.

Got it! did a little research on the matter right now, it's supposed to be around 2022 right? I know people here don't work for AT&T, but I'm sure some are more knowledgeable on these types of things.

Will custom ROMs be useless after that happens as far as calling? I use google voice with hangouts through an AT&T MVNO sim card.

Is it better to upgrade the H910 right now while it still has value for another 2 years?

Does the H910 support Volte on stock ROM? Will it matter? Or is it one of those things AT&T will force people to upgrade to newer phones.

Google Voice and Hangouts work fine with just a data connection for calls. I use then on a wifi only tablet. As long you still get data you will be able to use GV for calls. Effectively GV is already doing Voice Over LTE. Only native phone app calls using VOLTE and the SIM associated # may be disabled.
[LG V20 Guides, News, & Discussion] :
i'm currently on the latest RR and the included app "gallery" is awfully slow due to sd-card access i think. When i tried LOS 20200705 it was hanging when i tried to browse the sd-card with the included file browser. my device is a h990ds, let me know if anyone ever faced a similar problem.
[LG V20 Guides, News, & Discussion] Merazomo:
I truly apologize for being redundant, and I know this Volte things is still more than a year away; however, the SIM card is where I get my LTE Data from to use google voice and hangouts. Speaking hypothetically here; If the SIM associated # gets disabled, won't that disrupt the cellphone service (LTE Data included); specially if this phone is not supported moving forward?

Seeing how my friend got an email not that long ago saying his device wasn't going to be supported, even though he has a top of the line Samsung phone, makes me not trust AT&T in what phones will be supported; or if the H910 will be supported.
[LG V20 Guides, News, & Discussion] holistone:
If ATT is aware of the IMEI of the phone in which the SIM resides AND are aware that the current OS does not support VOLTE then they may, indeed, disable the account. More likely they won't know the phone and they can't tell if you are using stock or not so they will most likely continue service and you would be able to use LTE data. ATT does offer data only plans and I see no reason why that couldn't be used on the V20.
[LG V20 Guides, News, & Discussion] cnjax:
Simple solution is to a stock based rom and this won't be an issue. The problem lies with Los because volte doesn't work on it.
