I think it might be Open Gapps, i tried the booting without flashing OGapps or magisk and it booted up just fine
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] G U C C I:
I would just clean flash 15.1 with no GAPPS as that always booted no matter what. No Magisk, No GAPPS. Nothing. Clean flash.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Lillievela:
what i ended up doing is clean flashing 15.1, no magisk or gapps. Then flashing magisk and gapps for 15.1, then dirty flashing 16, rebooting, then the kernel, and gapps. As of right now, no sms
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] EnterTHEvoiD:
Which gapps are you using?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Lillievela:
the latest for android 8.1 and 9.0 nano
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] EnterTHEvoiD:
Cool, just make sure it's arm64 android 9. What happens when you try sending an sms? Also have you checked your APNs?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Lillievela:
Just doesnt go through, I dont receive any either.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] EnterTHEvoiD:
If yo go to your settings, network and Internet, mobile network, advanced and access point names do you have that configured properly and accordingly to your data provider?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Lillievela:
Ive checked many times after ever flash, I dont know why it doesnt work. Ill just wait till either something that works comes out or stay on AO for a while, give my phone a break from wiping and flashing so much

o2 germany

Hello, a bit off topic but is somebody using the H918 with o2 in Germany?

My o2 sim cards dont get a data connection for all services with this phone, while vodefone is doing fine. I tried flashed diffrent Modem driver.

Checked and also manually enterd the APN settings. The strange thing, threema messenger sill seems to work. Maybe doesnt use port 443/80.

But i cant use any webbrowser or other services, that require traffic. Like Lime E Scooter.

Any ideas? This happens with all H918s devices i have.

The SMS not working has plagued me through one clean install and two dirty flashes. I've found that making a phone call (*86 to voicemail is the easiest for me) and hanging up right after the call connect will get SMS's working again. Maybe your problem is a different problem, but it's something to try.

A little more about my situation in case someone has a suggestion or permanent fix:

I have a VS995. I was running SuperRom for a couple of years and decided to install something a bit more current. I gave resurrection remix a try, but had huge heating and charging issues that I couldn't resolve. So I switched to LineageOS.

I did a wipe everything / clean install of lineage-16.0-20200110-X86CPU-vs995 and had problems with SMS working. I have since done a dirty flash of lineage-16.0-20200204-X86CPU-vs995 and lineage-16.0-20200303-X86CPU-vs995 with no improvement. I have been unable to identify the cause of the problem. I'll make a phone call and get inbound/outbound SMS working, then a few days later notice that an SMS that I tried to send would get stuck. I then make a phone call and I'll receive all the SMS's that were sent to me since the problem reoccurred.

My provider is US Mobile, which uses the Verizon network. My settings / network type is set to Global. I've tried some other CDMA type networks with no improvement. The APN is set to VZWINTERNET with no ability to add or edit APNs.

I picked up the phone trick from the main RR XDA thread: "Verizon users (regardless of phone model): You need to make an outgoing call after booting to be registered correctly on their network. Calling your voicemail is an easy way to do this."

It sure would be nice to solve this permanently.

If I fully decide to attempt... I'm currently on ls997 Nougat and was wondering if I messed with flashing this would I be able to switch back an forth between this and stock 7.0 with no issues? Sprint implemented arb in 7.0 ZVD as I'm on 7.0 ZV7 no ARB (obviously for root stock) is why I wonder. Don't wanna brick due to ARB and switching between stock 7.0/custom 8/9/10.0.

I mainly wanna try because there are some things only available for 8.0+ I wanna try.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mivvv9lives:
Good evening everyone; I just wanted to make a small reply as an FYI for people who have sim problems.

I was using super rom for a while, until I've noticed that V20 was going to get official support from Lineage.

So I decided to install LOS again from our favourite dedicated dev.

Unfortunately, I've also been plagued with a "no sim" problem. I've tested clean and dirty installs for one whole day and I can only say one thing.

No matter what trick I tried, or what kind of dirty/clean flash I've done, I'm stuck with a no sim after 5 minutes.

Phone is H990TR, using H990DS flash for it. I'm glad I don't have to use my phone that much since internet is all I need; but if anyone knows how can I fix it I would appreciate the help.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cnjax:
Someone else who has a 990tr flashed another variant's firmware also sim functionality so that is probably the cause of your problem
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mivvv9lives:
Ah damn, is that so....

Well; after many flashes and weird stuff; I managed to get a weird working status.

The sim will stay on for indefinite duration, but will eventually fail, forcing a restart to get the functionality.

(I don't know why; but not using wifi seems to increase the working duration.)

Also as an update; 16.0 is the latest sim card working one for me. I couldn't manage to make sim card work for 17.1

GCAM 7.3

Ive been testing GCAM 7.3 for weeks now usint H918 and the one that worked for me is

trCamera_V4_Stay_Safe_Lite_Google_Lib_only

change the front camera to Nexux6P(...default setting/model settings)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] G U C C I:
There's also many others that work but if you're still on LOS 16, then your options may possibly be limited due to Android 10 introducing new APIs and features. I'm on Android 10 and most of the GCam 7.3 builds work just fine for me.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] nwananka001:
I have installed all the versions of the 17.1 Rom for my H918 device and the Gcam 7.3 though "works", front camera pics come out blurry. the one i mentioned is the only one that doesn't have blurry front camera pics. I only stepped down to LOS 16.0 because bluetooth call doesnt work for my device.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] aCIDsLAM:
Filesystem

Is there any way, i can get the rom to use another filesystem besides exfat on ext SD? I am getting corruption errors often with that filesystem on my SD. Forcing me to connect it to a PC, repairing the card,

before the LG V20 can use it again.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mangokm40:
Well, you could just format the SD card from LOS. This will not allow you to store files over 4GB, though.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] aCIDsLAM:
You mean inside the system, not TWRP? But wouldnt that be exfat too?

Maybe there is a way with magisk to add a filesystem?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] pm23:
I have the same issue with Los 17.1...can you confirm that bt calling and everything else works fine on Los 16?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mangokm40:
If you format the SD from Android itself, you don't get exfat. As I mentioned though, that means limit file size ~4GB.

In LOS16, the standard 'Files' app has a 3-dot menu.

After selecting your SD card from the main (3-line menu), you'll be in the top folder of SD card.

Hit the 3 dot menu and Storage settings->Format
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] softwaretech:
I too have an issue with BT calling. Music works, just not calls.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] pm23:
BT calling works for me, its a H990. I had 20b and I downgraded to 10c and installed the latest LOS 16, works with stock kernel as well as with Gammekernel v20. It did not work on LOS 17.1
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] lybxlpsv:
Camera does not work

I'm back from H990DS Latest Stock Oreo, LG UP to v10c and it seems LOS16.0 and LOS17.1 doesn't have working camera at all.

The same build was working before.

Kernel seems to fail when initializing camera looking at the dmesg.

LOS15.1 works just fine

Attached dmesg and logcat.

Hope this helps so that we don't rely on SELinux Permissive.

v14.1 and v17.1 are officially supported

The V20 series is officially supported by LinneageOS, with v14.1 and 17.1 available for all hardware, except the us996, which only has 17.1. Maybe you should consider moving to one of those?

I'm running an old version of v15, and haven't upgraded my h918 to an officially supported version, but I'm considering it. I like security patches. They are the only reason I'd consider an iPhone, because I'm tired of Android vendors' ****ty support. When there no longer is LinneageOS/decent community support for the V20 there is a good chance I, with very, very much reluctance, move to an iPhone.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] nwananka001:
I am different coz i dont really care for security patches, i rather have tools like privacy guard that i can use to control app permission and behaviour. I have used all versions of the rom on my phone h918. The reason i am back on 16.0 is because 17.1 doesn't have Bluetooth calling for bt 4.0+. Once that is resolved, i am definitely going to use it.

[MENTION=2881807]x86cpu[/MENTION] Would it be possible for you to fire up the compiler again in order to update the 16.0 build with merged security patches? That would be awesome :good: 16.0 is rocking the V20, it's much better than stock.

For me 17.1 is way too unstable (lockscreen freezes, BT calling not working, Wifi crashes) so I am going to stick with 16.0 for a while.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] jmichael2497:
i've so far wasted over a two weeks, across multiple days of reading, attempts, restore to stock, different combos of recoveries, to get lg v20 h918 working properly, with issues or shortcomings no matter what i try, really need official stock to los tested directions.

i was almost going to just go with LOS P unofficial to keep encrypted data twrp access instead of having to disable SELinux in LOS Q with Permissiver_v5.zip (suggested and seems to fix many things not working right, like disappearing camera, auto rotate sensors not working, clock resets, but then camera is crashing again)...

but the ir crashes after first use in both P and Q on my H918 device, so on top of losing fm radio... about the only benefit over my current s5 is going from 2g to 4g ram, since that has a consistently working ir under LOS P.

i'm so over the current state of android mobile technology, maybe i should just look for a replacement s5 since my screen is dying... or just use this v20 in stock O with Magisk mode.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Electrolite_XYZ:
Hey people, I installed Lineage 16, I'll try to give some opinions on it and also update if anything happens. I was using a stock Oreo when suddenly my phone bricked.

I own the H990DS, to install I did the following:

- 'Nuke' the phone with LGUP using the dl partition option (all partitions) to flash an old Nougat .kdz, this saved my bricked phone.

- Root with DirtySanta, including flashing the kernel provided by emdroidle and booting the phone once before next steps (I installed a newer TWRP already).

- Clean flash Super Rom Nougat to update the modem partition etc

- Use the 'factory reset' wipe option and 'wipe data' before flashing Lineage

- Flash lineage 16

- Wipe caches

- Flash gamma thermal mod

- Flash custom tasha xml provided in the gamma topic

- Flash Gamma Kernel v20

- Flash Google apps

Everything seems to be smooth. The system is gorgeous, it feels snappy and modern compared to the Oreo UI. Some key stuff that worked/issues:

- As usual it's a shame to lose stock apps like the HD Recorder and Camera, would be great if someone managed a port.

- The Quad Dac's amplifier (high-impedance mode) isn't working, even using the Gamma Kernel and after flashing the custom tasha .xml my high-impedance headphone just isn't as loud as it used to be.

I know this because on a stock rom using Spotify on the 'quiet' normalization setting and max volume almost hurt my ears, now max volume on the same settings and the loudness is low to medium.

I'm a huge music lover so this might be an almost deal breaker for me since I own .flac songs that are very very quiet. It might be hard to listen to those songs.

I tried to use Ainur Narsil, didn't help, I'll check if other Tasha settings might fix this.

- IR blaster is working fine (used SURE app).

- BT is working fine with my speaker.

- Viper4Android (new one) is not working, drivers won't install correctly. Maybe Audio FX (installed with Lineage is the one messing with Viper? I think they both alter some of the same files), the legacy one worked fine for me.

- Calls etc etc are working fine as expected.

If I notice other things I'll report but everything seems to be working fine. My only issue with this rom is how the high-impedance mode won't work which is such a shame since I'm really liking Lineage.

Let's see in the long run how the rom will behave.

EDIT:

I noticed I can't connect to my 5ghz Wi-fi, is this an known issue? It tries to connect then nothing happens, when I click to connect again it asks for it's password again like nothing ever happened.

Update on the 5 ghz:

I set the channel and bandwidth to fixed values, then I changed my password (was the same for the 2.4 ghz). Now my phone connects to the 5 ghz wi-fi perfectly and with good speeds.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] nexuserx:
This rom works perfecly fine on H910. To make dac working you need to manually insert files from tasha flashable zip, after that it will start to work. The zip file doesn't make any changes to system audio files for unkown reason. Remember to set proper file permission.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Electrolite_XYZ:
I was messing around a lot with the Tasha files and I think I found the issue:

The High-impedance mode on the quad-dac is working, the problem is that if you plug an high-impedance headphone, Lineage can't change the DAC settings to high-impedance mode, it's stays in the normal mode.

If I edit the Tasha files to force the high-impedance at all times then it works fine. So the issue is not if the quad-dac works, the issue is that it's unable to change modes when a high impedance headset is plugged and vice versa.

Now I don't know if it's even possible to fix or implement a mode changer on Lineage, but I've been thinking of making a bug report in the Gamma kernel topic.

Another issue I'm having: if I plug my phone into the PC, it can't detect it's internal storage, I can only access my SD card. I think the issue started after I formatted the SD card as external storage but I'm not sure (but the issue has been here pretty much since I flashed Lineage).

I tried to update LG's mobile drivers to the last 4.5 version but didn't help. I tried to search here but didn't find similar issues. I'm using Windows 10 19042 (october 2020 build), Linux can only see the SD card as well. Is this a setting for when you set the SD card as internal storage?

Is there any log I can send that would help finding the issue?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] lybxlpsv:
it is normal. all data will be stored on sdcard and the phone's internal storage doesn't exists now, or only exists as system and internal app data.

anyways quad dac doesn't work if you only use gamma flashable tasha zip.

you need the more changes for it to work. for more information please refer to one of my post here https://xdaforums.com/v20/developme...0-variants-t4076549/post82481703#post82481703
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mcsmart:
I've been having WiFi issues on my V20 ever since I got it. This was on stock, Lineage 16 and Lineage 17. I am running Lineage 16 right now (most stable ROM out there!) and I was finally able to fix the frequent WiFi dropping issues. It turns out it was related to IPv6 (I actually suspect IPv6 multicast traffic)! This also explains why some people don't have these issues at all as there might be people out there who only have legacy IP in their WiFi.

So long story short, if you have issues with WiFi dropping on your V20, try to disable IPv6 on the V20's WiFi interface. You can disable it with the following commands in a root shell:

ip6tables -A INPUT -i wlan0 -j DROP
ip6tables -A OUTPUT -o wlan0 -j DROP
sysctl -w net.ipv6.conf.wlan0.disable_ipv6=1

Those settings won't survive a reboot, so if it's working for you, you should add these either in a init.d script or run those commands through Tasker upon reboot.

And in fact this won't turn off IPv6 at the kernel-level, it just drops all IPv6 traffic at the firewall level. The sysctl-call does not really do much, it just forces a singe disconnect. Still that is enough on my side to fix dropping wifi connections. Please report back if this is working for you (obviously only if you are affected by dropping WiFi). Then we can file a bug on the LineageOS bug tracker so this can be fixed officially.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Electrolite_XYZ:
Thanks for the answer, I'm super eager to get the DAC working, would your flashable files possibly work on Los 16?

Oh no, I'm plan to get my SD card full of songs so that's not ideal. Maybe I'll format it as portable again.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] lybxlpsv:
you format is as portable storage. not format as internal.

anyways i've made a magisk module version you can check it out on this post
