H910 here. Dirty flashed from Lineage 15.1 (second screen variation with Gamma kernel). Followed all of the steps exactly as listed (flashing Magiska 17.3 & Open GApps 9.0 Nano). Phone does now boot into Lineage 16, works for about a minute... then says "Powering Off / Shutting Down..." & reboots into recovery. Tried pulling the battery & wiping caches again... no luck.

I ran a logcat log & got an output right upto the shutdown, which I've attached to this post. Shutdown happens right at the bottom, and you can scroll up to see the history. Looks like something in "blank_screen" perhaps? Tons of constant errors about wifi spammed the whole time leading up to the shutdown, but unsure if that contributed to the shutdown. Restoring a backup to Lineage 15.1 for now. Hoping this can help!

Just incase the attachment is acting up, I made a pastebin: https://pastebin.com/Z4CkWKpg

Dirty flashed my US996 and everything's working well except camera, third party cam app works fine though.

MagiskManager passes safetynet w/MagiskHide so I can even load/play Pokemon Go (in case anyone else is in the same boat).

Dirty flashed and forgot to install Magisk and GApps so things were broken. Did a clean flash because I remembered GApps after I had already wiped. Pretty stable for such an early build! Hats off to you! Can't wait for a stable build!

[H910]

-Battery Drain

*watching videos etc

-stock camera has terrible quality, none of the ported gcams work currently, haven't tried open camera yet

*confirm that zooming in camera mode freezes the app.

EDIT- zooming in freezes all cameras, including open camera and google camera

-only 2 issues so far , running it on a 910, smoothest beta ROM I've ran so far. haven't tried Bluetooth yet, but thats a confirmed issue anyway.

-I like the status bar on the second screen it looks pretty sexy

-thought 9.0 had lockscreen weather? Probably hasn't been merged yet, understandably

Keep up the good work [MENTION=2881807]x86cpu[/MENTION]

NOOBS! DONT EVEN TRY THIS ROM. IT WONT BE A DAILY DRIVER FOR YOU.

So far the only problem I'm running into on the H910 version is battery drain. I'm sure it'll get better through updates though.

Battery drain issues

Reflashing lastest gapps 9.0 then -> wipe -> advanced wipe, select ONLY 'dalvik/art cache' and ''''CACHE''''' -> swipe to wipe -> reboot and reboot a little longer itself rebuilds . Ur battery will be good to go.

I'm not currently running los16 but if I'm not mistaken in Pie when you take a screenshot in the notification panel there should be an option to edit the screenshot. From my understanding that's a native feature in Pie now and I had the same option while running the RR 8.1 rom on this phone. Hope that helps.

I'm having issues with Bluetooth audio on LOS 16.0 20181214. I use the Anker SoundBuds Slim+. They need to be very close to my phone or they start making a crackling noise as if the connection is weak. Even with my phone in my pocket it's too far away. With stock ROM bluetooth behaves normally, I can leave my phone on a table or in my pocket and go about getting chores done.

Earbuds: Anker SoundBuds Slim+

Phone: LG V20 VS995 (Verizon)

LineageOS: 16.0 20181214

Update: Same behavior occurs when I use these earbuds on my Windows 10 laptop which doesnt support apt-x. Could it be that apt-x shows as enabled but isnt actually?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] mikekote666:
Anyone that has a H990 DS that doesnt shut down after installing los 16?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Grin59:
Well either that this rom has Bluetooth issues because their early beta builds, or it's that this rom doesn't support apt-x but you should be able to use your earbuds without apt-x so I'd test with another phone that doesn't support apt-x and see if they still work.

---------- Post added at 03:35 PM ---------- Previous post was at 03:33 PM ----------

If I recall correctly this model has shut down issues. You'll have to wait till another build comes out that fixes the shut down issues
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] jtay419:
I dont have any phones without apt x unfortunately. However I did set the codec to SBC in the developer options of stock ROM and the connection was great. That probably rules out apt x being the problem

Also I tried another windows 10 machine. It has an intel wireless ac 3160 and there are connection issues similar to that in LOS
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
It might cause issues elsewhere (like breaking the Camera as other users have reported) but try doing a TWRP backup and flashing the test Gamma Kernel versions for LOS 16.0 (you can find them somewhere by searching this thread) and see if it fixes it.

If so, you can revert to the stock kernel by simply re-flashing the ROM (or restoring your TWRP backup) and that way x86 knows it's a ROM/kernel issue or keep using Gamma if it has no adverse issues.

It should be noted though, that Bluetooth is confirmed working properly ONLY if you upgrade from a previous 15.1 installation, and is listed as failing (as per post #2) if you come from a clean flash (which would be the case if you're come from stock).

H918 running 12/14/2018 Lineage 16 here. After several weeks living with the already reported short life and hot battery experiences, I persisted. Now I am happy to report my phone has finally settled down. No heat and all day long battery life. Very pleased. Don't know why but the schedutil governor's are now working correctly.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] jtay419:
Flashing Gamma Kernel beta 3 for LOS 16.0 didn't fix the issue unfortunately. Music works OK, but anything with video such as YouTube and Twitch results in a bad connection. I believe this was the behavior before installing the kernel as well

Update: It appears wifi is a potential cause. I used LOS 16.0 with stock LOS kernel and Gamma. The network I connected to is 5 GHz. When I play a local video with a seperate file downloading or browsing the web, there's crackling, dropout, etc. When I play a local video with wifi off, the connection is perfect. Next I will test with LG stock ROM to see if wifi affects connection there

Update #2: LG Stock ROM works perfectly as expected. No connection issues with wifi on while watching Twitch or YouTube

H918 20h bootloader/tz/whatever, running lineage16 from our friend x86cpu. Only things not working are FPR, and Flashlight. (Works in camera fine)

Other issues

include reboots randomly. I can't catch them because they're usually after I've set it down and am working. I don't know if its a kernel panic/demigod or if system is crashing.

Rebooting when dealing with Bluetooth low-energy stuff.

Anker Roav BT FM transmitter/charger, Fitbit Blaze

If you need a buildbox, let me know, I'll set it up. 100mbit down/10 up, 2.6GHz C2Q, 8GB, 500GB set aside for ye. Sitting idle in my closet. I know the specs aren't great but I've built on it before and its pretty fast. 10-20 min for lineage for h811/g4

I recommend Kernel Adiutor. Have been using it since I started running custom ROMs.

I recommend conservative on the big cores and interactive on the LiTTLE cores, with the minimum frequency of 307Mhz selected.

As for the GPU, I leave it on stock with the maz frequency limited since I don't do any gaming.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] nickthaskater:
Is there anything in particular that needs further testing to get this ROM to the "next step" of development, or is it just a matter of time for now?

I'm happy to load it back up and take a more targeted approach to usage if there are any lingering points of concern.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ESmazter:
You need people who dedicate their time to work on this. Our dev is busy with his life which is a more than acceptable reason. If we had more than one developer, this might work faster but until then lets' be happy for the occassional security updates :)

That's literally what I'm offering to do - I just need to know what to focus on. I'm not complaining about a "lack" of updates.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Zizo159:
In the last update everything worked very well except for games(at least for me on the h910). It's the performance to battery that needs the most work. U can increase performance but battery suffers heavily. If u prioritize battery the gaming performance suffers.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ESmazter:
There is the CPU overheating issue and the reboots with inserted sim cards for H990DS users. I think these are the main concerns at the moment. Other than that, merging the latest los updates is always welcome.

Excellent work on this ROM. I originally came from the Alpha Oreo ROM and had nothing but problems the first few times I tried to run this (crashing, massive overheating, fingerprint reader not working, wifi broken) but after going back to stock Nougat and completely wiping and recreating all partitions and then transiting via LOS 15.1, this is running perfectly. No overheating, excellent battery life (I think the best battery life of all ROMs I've tried). Actually, I'm a little shocked as I think it's the best ROM I have ever used on this phone so far.

Can you explain what exactly you did in a noob friendly way? Sorry, but I really want the same result that you have and, want to do exactly what you did.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Messaibi:
Fully wipe and format your phone, doesn't matter what rom you're running

Flash any nougat stock rom then boot to system

Go back to recovery, fully wipe again, this time flash to-x86cpu and restart to recovery

Install lineageOS 15.1

Boot to system

Go back to recovery, flash lineageOS 16 on top of it without wiping.

That's what I did and I got similar results to what he said, hope this helps.

The best thing to do is to try what Messaibi has suggested first. The way I achieved my stability is not recommended and is certainly not "noob friendly" as you might put it. In fact, I've bricked my phone twice in the last week from navigating the obstacles associated with the weird method I used. Anyhow, I can provide some extra thoughts later pending your experience with the more "sensible" method Messaibi has described:)

I used this to downgrade my firmware back to nougat:

https://xdaforums.com/v20/how-to/guide-downgrade-8-0-firmware-to-7-0-t3882290/amp/

Then wiped system, data, cache, and finally format data, type yes to format.

Afterwards installed Los 15.1, gapps, anykernal ss91 with recommended audio patch and thermal patch and wrapped up with magisk 18.

Booted to system, reinstalled all apps, customized phone, used it for a full day getting everything back how I like it then backed up data via twrp (just in case upgrade didn't turn out well.)

Installed los16, gapps, and magisk 18, boot took about ten mins but after about 6 hours seems stable minimal heat, and no deal breakers.

Best test run by far and hope this can be my dd. Hope this helps.

Searching 'Gamma' in the thread will lead you to it.

The "Xposed for Pie" is an unofficial fork someone did themselves instead of waiting for the actual Dev to update the official Xposed, so be careful with that.

Wow, so some massive potential with this rom. VS995 owner here reporting in

As warned, a clean flash will blow out the mac address of the Bluetooth (Doh’!), so I flashed a 15.1 resurrection remix rom, did the initial setup with 15.1, and then flashed this 16.1 rom. After flashing 16.1 the first boot looped - had to pull the battery, however after that It booted in like 20 seconds, reboots are incredibly snappy with this rom.

Dirty flashing over a version 15.1 (boot up on the 15.1 rom for a bit, you cant just flash one after another in twrp) will make bluetooth work perfectly, minus the notification in the status bar not working when the device is unlocked. When locked, the Bluetooth icon in the status bar with battery bar shows up, oddly enough. Smartwatch synced right up, and connections to car / headset are perfect. I am sure the garbled audio issue is still there, but have not confirmed.

The phone did get stupid hot on boot, switching to power save with kernel auditor did fix that, it is now nice and cool, however I am going to play around with the modes to get the best performance vs heat vs battery drain.

You still need to place a call after reboot to get any incoming calls / texts

Battery life is abysmal. Going to run some wakelock detectors and try and find out what is draining things. I have an extended battery I am going to snap in (man I miss removable batteries in flagships) to help boost battery life for a bit.

Second screen is smooth like butter, I love it!

If anyone needs any logs or any help diagnosing anything let me know. Thanks for your dedication to the V20. Thanks to you guys, I am going to have this phone till someone pries it from my cold dead hands.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vs995Child:
Yeah the vs995 has done a little better than most, from what I have been reading. I came from the AOKP oreo version, and like you, the Bluetooth works great. I do still have a few heating up issues, still trying to find that "sweet spot" with the kernel auditor (or however you spell it). This rom has been my daily driver for a couple of months now. I know once the dev smooths things out, it will really be great. Keep us posted on your kernel settings when you find that good combo...

The only issues I have with vs995 is inconsistent battery charging. I can plug it into a QC 3.0 battery pack and it will display charging slowly and the charge is slower than the drain. I use Voltuz usb C cables the yellow one gets slow charging, The Red One Gets Slow Charging.
