Coming from resurrection remix pie 7.0.2, I wiped system, cache and dalvik, Then factory reset. Started with just the bare lineageos and no gapps. It needed a reboot first. But it worked. I rebooted into recovery. Installed gapps then. Voila! Nothing complicated really

Remove the battery, insert it, hold vol down and insert USB cable. It'll take you to fastboot mode. Then flash TWRP, then install a rom and kernel to fix the static

I'm not expecting anything on the charge or freeze, which I am not sure what that's all about.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] EnterTHEvoiD:
How did you fix it?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] darkknight200:
It was leaving the active v20 on and then charging it for about 30 minute without touching it. Then i come back after a while and try to unlock it with fingerprint and it will buzz but the screen will remain black and then it becomes unresponsive and doesn't recover. Only way to get it back is to pull battery and then it boots up fine like normal.

So far with the build prop line added, it hasnt frozen while charging so i say it fixed that problem too

nvm it just did the same thing i described up there, will try to capture logs nex time

To clarify , the v20 on official +stock los kernel is having that problem of locking up when charging

the v20 on x86 17.1 + gamma v20 kernel isn't having the problem charging

I am going to flash gamma v20 on the official los and then do charging test and see

** ok after a long time charging, i think its safe to say there is no locking up charging on the official los + gamma v20 kernel

Who do we report all these issues to so that they can get fixed in the official version?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
The same developer handles the unofficial and official. There is a Jira bug tracking too. You are more than welcome to use it, it won't fix bugs any faster and could if not fixed have official builds pulled too. That being said, there is nothing that does not meet the Lineage Charter for official builds.

You, yourself can also fix things and submit then to gerrit as well. Fixes will go into unofficial before going into the official.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] alexp1289:
I just wasn't sure if there was someone specific we needed to give the logs to. I don't know how to fix anything but I can take logs and send them to whoever needs them.

i did try the fix suggested [MENTION=2881807]x86cpu[/MENTION] and it works, from the moment the option to choose which app opened a video i knew there was something but thanks for the fix.. can actually go to 17.1 now

I'll work on getting that into the codebase now. I've had enough confirmed cases on the V20/G5 threads.

great. thanks for making it happen.i have a question, going forward what will be the difference between unofficial and official?if any
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
Unofficial will have some tweaks I add that are not allowed for official, plus fixes/changes/testing will happen on unofficial. Once confirmed it will be merged so the official will get it.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] alexandero11:
Thank you so much for getting the V20 back into official development, you are amazing! I just got a V40 and had to RMA it (stuck pixel, very noticeable on the crappy pentile layout) and I'm unsure that I will get another due to how much of an overall downgrade it is from the V20. Unfortunately, some of the biggest features I use very heavily are not supported by the V40 or by your ROM on the v20: proper second screen support (a second screen LCD like this is THE ONLY PROPER way to do an always on display in my book, no burn in, no stress) and the hifi DAC (yes, I use it multiple times a day). Is there any chance the hifi DAC will be working and is there a way to shovel in real second screen support? If this can be done, I would probably be willing to open my wallet, no joke, these features mean that much to me and I get that much use out of them.

If I have an ARB0 H918, would installing the official build trip ARB1? Do I have to wait for the unofficial build PRE-10P build to flash? Thanks.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
Odd. It should not matter. It could though as the unofficial is about a month behind, which I'll get updated once security patches come out.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
Most likely it won't boot at all. There won't be any pre-10p for official, not any us996-ds either.

I do monthly builds with updated security patches. If I need to do a sooner build I will too.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
Most likely never. LG does some proprietary stuff, so until someone can figure that out most likely never, this includes volte too.

Then again, LG doesn't update stock anymore, so it depends what is not important to each person.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] sjavvaji:
Good to know. No worries. I'll wait for the monthly build release. Thanks for all your work!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] alexandero11:
Bummer. I still cannot comprehend how the Korean Pie stock firmware has not been ported to all variants. Why has it not happened? There's obivously intrest, there are plenty of comments and posts detailing how people want proper second screen support and multi camera use in all apps and quad DAC support and VoLTE. Seven years ago, that would have been something that would have happened just because it could even before the realization that most variants weren't getting it would be revealed. It's sometimes depressing to see how much the custom ROM dev scene has changed, but I know it's largely Google's fault, so no hard feelings. It really does annoy me that nobody makes an effort to answer this question though. Is the answer really obvious and that's why nobody is taking it seriously? I do know a few of the basics so I'm tempted to try porting it myself, but if there's something I don't know that would make it a fools errand then I'd like to know. Thanks.

stock rom to 17.1 unofficial

hello x86cpu,

i'm newly here. so i'm now on rooted oreo stock rom (h990ds) and want to try this 17.1 unofficial rom.

can i just factory reset from twrp > flash to-x86cpu.zip > flash directly lineage 17.1 rom?

or factory reset from twrp > flash lineage 15.1 > lineage 16 > lineage 17.1?

thank you.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cikenkari:
is your bootloader h990ds unlocked?

if not you need to downgrade to 10c using LGUP,

then follow this method to root, https://xdaforums.com/v20/development/dirtysanta-h990-t3624296

once you're in TWRP you can install the lineage 17.1 zip
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] lallolu:
I was also thinking about this the other day. I guess the motivation to always port and build custom ROM has greatly reduced because android is now a very mature OS. Unlike before when there was usually one bug or the other, features lacking and not to mention the lag in those days. Porting would definitely have happened if it was 7 years ago. I rememberd my HTC sensation which HTC never release andoid 4.1. We go the version from a developer who ported it from HTC One S. Porting new UI from a newer phones was very common then, especially on Samsung and HTC phones. Great times.

If you mean my LBFM™, then yeah- it should. I made it for stock based mainly, but might work with Lineage, I'm not sure tho. I can't test because no one will answer my simple question lol.

I've tried to find the differences between the gamma kernel IR and Lineage. I have not been able to track it down. If anyone is willing to compare and has any ideas let me know
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Brophen:
I have 0 idea where to look but I'm giving it a shot. Would /drivers/media/rc be the right place to diff? Wish I knew when it started working, I don't see a mention of "Hey this works now" anywhere. Maybe it was working in lineage, Gamma forked, and then a "fix" broke it in lineage instead? https://github.com/LineageOS/androi...mmit/b02dac504efc353e1e8507c10f835f09757b0068

If I'm on the right track I'll poke around further
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
I believe it was working in 14.1, and since 15.1 it has not been. It can send 1 command via IR (serial port), but then hangs for about 2 minutes, and times out, then it will work 1 more again...etc. I'm pretty sure it's part of the serial port area.

https://github.com/LineageOS/androi...ob/lineage-17.1/consumerir/ConsumerIr.cpp#L33

That's where it is pulled in via userspace. It uses the try serial port.

Since only the gamma kernel does work, it points to the kernel...

These are set in the defconfig:

CONFIG_SERIAL_MSM_HSL=y
# CONFIG_SERIAL_MSM_HSL_CONSOLE is not set

The kernel area for that is: https://github.com/LineageOS/android_kernel_lge_msm8996/tree/lineage-17.1/drivers/tty/serial

Only these are compiled in: msm_serial_hs_brcmbt.c msm_serial_hs_lite.c msm_serial_hs.c msm_smd_tty.c serial_core.c (all of these are identical for gamma and Lineage)

It could be in the try area too.. Really unsure where to start

Guys, does any of you know where the alarms, ringtones and ui sounds are in this ROM? In LOS16 they were in system/media/audio folder. In LOS17.1 they are

not there.

At first I thought that is some Android 10 thing but I have LOS17.1 installed on some other phones and in those builds they are in system/media/audio folder.

I am asking because I would like to replace some of those with Stock LG sounds, as I regularly did while I was on LOS16.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] G U C C I:
Yes it depends on the rom. They go off of the stock rom when they write those articles. As far as I'm aware, Lineage cannot do 60fps, however the stock rom can. Probably due to proprietary drivers and such.

Since you are the maintainer for the official build, can I ask a question pertaining to that? I did my best searching Le Goog, XDA, and reddit unable to find my exact situation.

I'm running the official April 23rd 17.1 on h918. When I am on a phone call, the proximity sensor correctly works and causes the screen to go blank like it should when you bring the phone up to your head. However the sensor fails to work when you pull the phone away from your head. In order to turn the screen on, you press the power button on the back. Any advice is appreciated.
