WARNING: DO NOT ENCRYPT! YOU WILL CORRUPT YOUR ENTIRE DATA INCLUDING INTERNAL SDCARD
(Please do it carefully)
Disclaimer
Your warranty is now void.
I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed. Please do some research if you have any concerns about features included in this ROM before flashing it! YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.
Introduction
LineageOS is a free, community built, aftermarket firmware distribution of android, which is designed to increase performance and reliability over stock android for your device. More info.
These are my UNOFFICIAL builds of LineageOS-15.1 for LG V20 variants. I did NOT create this ROM. I am helping to contribute to this ROM. Thanks to all other coders who contributed to LineageOS.
IMPORTANT
BACKUP! These are UNTESTED builds. Please be ready to recover your previous ROM. If it kernel panic, boots into bootloader, etc... grab as much info as you can.
Builds are done periodically (see download below)
Do NOT be rude.
Respect all users.
Any and all users, please help each other. I have a us996 variant, so other variants might have some issues.
Known items
Lack of 2nd Screen Support
VoLTE and WiFi calling do not work yet
Other known issues (same as OFFICIAL too):
us996 static on boot: Unlock bootload from LG, using dirty santa causes static on boot, will not fix. (sorry)
WiFi or Bluetooth MAC is "00:00:00:00:00:00" - You wiped the misc partition, you'll need to fix: https://forum.xda-developers.com/showpost.php?p=70474540&postcount=12
5Ghz tether not working due to "error"
Enabling ADB Debugging in development setting can cause a kernel crash. If you are quick and press OK right away, it will take and still crash. On reboot, it will be enabled.
H918 - ARB1 .. flash the 10p version, ARB0..flash the PRE10p. (10p is where the ARB got tripped to 1)
Install
You can upgrade from 14.1 (UNOFFICIAL) to 15.1. If you are not on my UNOFFICIAL yet, flash the to-x86cpu.zip first (and reboot recover before upgrade, not reboot into system).
I would suggest the TWRP from Phoenix591 (See Thanks section below)
Flash to-x86cpu.zip if you want. (See Downloads below)
Flash UNOFFICIAL ROM
Wipe cache, and dalvik cache
Magisk if you choose
Flash GAPPS (I use nano)
Reboot and wait....
(Copied from OFFICIAL thread)
To enable Developer Options go to Settings, About Phone and repeatedly press Build Number.
If you use ADB read this: PSA by CM
If you use reboot to recovery read this: PSA by CM
Regarding new Superuser: PSA by CM
Bugs
If you encounter issues/bugs that are not known, please report. This is not the OFFICIAL ROM, but I can help to get any issues fixed. I use the us996 variant. If I can replicate your issue then I can track it down. If I cannot, please provide as much detail as possible. Logcats are great.
Please indicate what v20 variant you have (h910, h918, ls997 us996, vs995, h990/ds) and what you are running (OFFICIAL or UNOFFICIAL) and date. Any mods (no judgment) as well.
I am aware people run mods or change things. I am not against it (as I do myself). However, if needed I may ask you to data wipe (you can say no), or remove a mod that might be interfering. I will do the best I can.
Thanks
Any and all users in this thread who contributed or will contribute to making this ROM as stable as possible

What is not working or problematic
What is not working or still wonky:
Encryption -- Works.
USB OTG -- Should be working.
Ambient display -- Disabled now.
Livedisplay -- Should be working.
IR will work, then timeout, then work again.
Video recording -- Should be working. Works sometimes, appears to record, but playing back audio is at the beginning, video at the end, and the duration is messed up.
5g tether -- Not working still.
No FM driver.

Freakin' lit. Flashing it on my VS995 now. Awesome work!

---

Thanks for your effort for bring LOS definitely I'II try this later tonight on my vs995 .

---

Thanks a lot sir, @x86cpu, your dedication should be an inspiration and I implore all users to thank and possibly donate to this dev. Make him rich. I would say this thread is XDA portal news worthy.

There can still be bugs I haven't found. I tested what I could on a us996 using a VZW sim. Apparently LTE might be a bit weird in a vs995 device.

I'll have to check into it.

Its great that you're able to get this up basically as soon as the april fools thread was locked and disappeared XD . Will be installing soon.
Edit: Like others are saying finger print reader is MIA (US996).

---

On the vs995, so far so good. Only thing I see missing is the fingerprint sensor. But maybe it's been moved

---

Couple more issues:
Encryption is probably broken: I let it go for an hour and the ETA was still at 0:00 like it was the whole time ( I had only a handful of apps installed and in 14.1 it only took around 5 minutes).
Enabling adb caused the whole system to crash and reboot, but it did seem to be enabled afterwards.
Still enjoying Oreo benefits like YouTube picture in picture mode

Can confirm fingerprint is missing.
@x86cpu Thanks for bringing Oreo to our devices! Very smooth experience so far except Ambient Display seems bit sluggish. Disabled it and its all good now.

I'll have to check encryption too. Did you upgrade from 14.1 encrypted? Or just try to enable the encryption? (ADB kernel panic is a known issue right now.)

This was enabling from unencrypted. Had handful of apps but none of my large ones restored yet so it should have been really fast.

Confirmed on the h910 as well, enabling causes a crash and reboot

I thought It was the April Fools post. I'll be waiting for the ARB1 version for my phone

So is HiFi DAC working? I thought it might not be possible...
