It has the same bugs as Lineage, wifi calling, I can't remember if it actually works or not. Maybe it does with Gamma kernel because I think I was able to use wifi calling. The 2nd screen isn't completely stable but definitely usable, and don't ever count on getting VoLTE on this phone unless you wanna create it. If I remember correctly, it's something that's made by LG and is proprietary. Like the 2nd screen, it was proprietary and had to be recreated.

Hey guys, I installed Lineage OS lineage-15.1-20181214-X86CPU-h918-10p.zip and now I am stuck at the rotating circles screen for about 1 HOUR.. going to patiently wait even longer.. but in the meantime, I realize there is contradictory information in the first post.

On one line, it says "Flash to-x86cpu.zip if you want. " and on the first line it says "If you are not on my UNOFFICIAL yet, flash the to-x86cpu.zip first"

I ended up not flashing this mysterious to-x86cpu.zip file... Will I have messed things up by doing this?? :( Also I didn't install SuperV20 Prerequisites-H918, could that be the issue? I didn't install Gapps either.. maybe that is a problem?

How long is this rotating circle supposed to take??

EDIT: RESOLVED. Pulled out battery, put it back in again, now booted into Lineage.. WEIRD!

Call record working too. I didnt even need to change the lg ui-call apk. I recently moved over from alpha. I95swervin shut down development with do cause. Lg screwed us and, he moved on. I had to also. Instead of device right now, I chose to move to lineage. It has been my daily driver ( personal tweaks added also). If you are going to keep your V20 this is the rom to have.

I am so sick of the lock down that Oreo has placed on the Navigation Bar. What is the best way to swap the back button to the right instead of the left. I don't want to install apps that add additional nav bars, etc. We have root so this should be a piece of cake, is there a good module that can take care of a bunch of these things, similar to how I used to have on my PureNexus 6 device?

Silly stupid me.. and damn so helpful! Thank you!

---------- Post added at 11:24 PM ---------- Previous post was at 11:10 PM ----------

Just out of curiosity, what is the current best stock ROM that can be flashed onto the H91810p device? By best I mean being easily able to switch between LineageOS and which version of stock ROM? Because after reading all these forums, people are saying that going from an Oreo based stock rom back to Lineage 15.1 causes headache, problems, and broken things. it would be great if I could easily switch from stock ROM to Lineage and back on the fly with just restoring the system/data/cache partitions, given that my initial KDZ flash was 10p.

And second question.. the in-camera app with LineageOS is pure garbage compared to the LG stock cam.. pixel peeping at 100% shows crazy amounts of artifacting and distortion.. normally I used the CSpark version so will try adding that.. hoping that isn't a problem.. :( Also even with the LiveDisplay off.. the brightness of "white" color doesn't seem as bright as my previous phone/rom. Might be the phone, or the rom.. but not quite sure yet.

Thanks!

Yes... this is known. It doesn't happen all the time. Also enabling usb debugging in the development settings causes it too. Still being investigated.

I can't install this rom because is said my device is not us996

But Im sure my device is us996

how I can install it?

Sorry because my bad English

Dumb question how stable is this rom I know it's unofficial but I've been dying to try out Oreo, also if I flash this rom and don't like it can I flash back to a stock nougat rom i.e WETA would I be fine

Also I'm still on 10k update would that be a problem
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
Go to page 1 if this thread. Find the "Thanks" section. There's a link to the right TWRP. switch to that TWRP then flash the rom again.

You can do all of that. Just make sure you use the right TWRP. SEE MY LAST POST. back up first.

I can't express my appreciation enough for you building this. Everything has been smooth so far and I don't think the stuttering issue I was having on LOS 14.1 exists on this. Only thing I've noticed is I always get a kernel panic when setting trying to change to MTP file transfer mode. Otherwise I've just been using AirDroid. Thanks for keeping this device alive. (US Cellular variant btw)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] :
H918 user here with issues to report.

Installed this ROM on 04/13/18 and ran it straight through the weekend. Only have a few issues to report. I apologize in advance if these are already known issues.

1: Phone does not unlock right away when using the finger print scanner / unlock method.

Explanation:

- From a fresh reboot the phone will unlock itself as expected when using the finger print method. However, that is where the stability stops. Once you lock your screen for a second time, going back in takes some getting used to. Putting my finger on the button does not wake the screen and get me back into the system. I have to "physically push the power button" then "take my finger off for a split second" then "Place my finger back on the power button" After doing this the phone will unlock. This is not a HUGE issue to report as I am able to get back into the phone, but thought it should be mentioned.

2: Sometimes when unlocking the phone I will be presented with a black screen with only 3 navigation buttons at the bottom

Explanation:

- (these buttons do not appear to be functioning or have any affect when pressed). Pressing the Power button to lock the phone again is the only way I've found to alleviate this (besides an obv. battery pull).

3: Disconnect from USB crashing Kernel / System.

Explanation:

- When the phone is connected to a PC via USB, it would appear the Kernel crashes / phone freezes when unplugging the USB cable from the phone and/or PC. Not a HUGE issue for me, but for others this may get old very fast.

4: Kernel / System crashing when enabling USB debugging via DEV. options.

Explanation:

- I found this issue when trying to pull log cats for better issue reporting. However ADB will not see my device unless USB debugging is enabled. When trying to enable this feature my phone/kernel freezes for a good minute then reboots.

I am sorry for not being able to supply log cats. If there is anything I can do, please let me know!

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] bmooney1988:
I really like the smoother and snappiness of the rom but I always come across the MAC address being 00:00:00 etc. Is there a way I can flash the rom without it defaulting to that? I'm on Super V20 for the time being? I'm using H918 on 10p
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] :

I think these two issues are related to ambient display. I had similar issues to this; disabling ambient display solved the issues instantly.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] :
You are 100% correct. Disabling ambient display resolved those mentioned issues. Glad that's over with, that was annoying. Thank you Sir!

1/2 are the same issue.. ambient display..disabled it and should be ok.

3/4 are the same too, working on it. For #4... sometimes it is enabled after a reboot...sometimes it takes a couple times.

Look for the display settings, there are some options turned on by default like a blue filter when it's night etc, etc if you turn off all this stuff the brightness will look like the original one.

Yes use the new Gcam by Cstark (maybe i missed his name), I like the latest version with zero lag shutter and the night mode, great stuff

Do i need to restore saved ROM before trying to flash 15.1

I am able to boot to LAF, which has TWRP 3.2.1. I can also boot to recovery, which has TWRP 3.2.3-4.

I tried loading the OFFICIAL 14.1, but the phone won't boot. After the LG screen, it just goes blank.

Should I restore the saved ROM (backed up after LAF TWRP install, before Recovery TWRP install)?

Or, should I just try to install the latest UNOFFICIAL 15.1 now?

thanks

I can confirm that Redline is absolutely correct. I have been running this rom for close to a full week now. The only issues that I have noticed is at most those but, I honestly have no personal issues with this rom. It's been stable enough for me to trust as my daily driver.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] :
the first post in this thread says that the second screen is not supported, voLTE and wifi calling are not working, 5Ghz tether not working due to "error", enabling ADB Debugging in development setting works after a crash and reboot.

Is that still the case? mainly i'm watching the second screen, this is the most important in these issues. What about IR, FM radio, OTG, and video recording?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] scorpio76r:
You have to use the 2nd screen rom found in the Google drive folder. To me stock has a better ui but, the 2nd screen does work.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
Like [MENTION=7200067]scorpio76r[/MENTION] said, you need to use the second screen version OR use the second screen builds of ResurrectionRemix because they're more up to date than LineageOS' second screen builds.

I imagine second screen is still not listed as working because it's not part of the base builds in 15.1 (like it is with 16.0).

VoLTE isn't and won't ever work, same with WiFi Calling (except for one case I saw in another thread a few days ago where someone got it working under a specific case), 5G tether doesn't work, I've never had an issue with ADB Development settings, always works fine for me.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vortell:
It seems I'm probably wrong here but I thought it was possible with most phones to get volte working if the network you choose has implemented the Google accepted standard volte. For instance I am pretty sure it was possible to get volte working on los 14.1 s5 but only on T-Mobile maybe one other network. It's honestly only thing holding me back from using custom rom on the phone. T-Mobile coverage in my area is more 4g then 3g. Big 600mhz release here. Oh well not sure how much longer I will have the phone. As screen burn started on both sides and have a warranty on it. They can't find a place with us996 I guess...
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
That may be the care r.e. specific network variants getting it working at some point, but I suspect it's not a priority (if it's even possible) due to how complicated the RIL-stack is on the V20 (at least here on the H990/DS variants).

If you haven't already, it might be worth updating your /modem to the latest non-v20a KDZ release using KDZWriter, doing a full TWRP backup and giving LineageOS a go to see what service is like on it, worst case you try it for a bit and if it doesn't work out you just restore your backup.

If you've not already (and want to continue on stock) you could try a kernel like mk2000's stock version and/or use KCAL to try and mitigate the burn-in.

Unfortunately, the only REAL ways to keep it at bay are to keep the phone itself cool and not have the screen be bright.

Only my opinion, lineage is the only option that we currently have if you want security updates and possibly a stable pie rom soon. If you wait for lg to do it, that could be close to the end of the year if it happens at all.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Grin59:
Don't forget about Resurrection Remix, Lineage lacks a lot of features. Also, we will never get Pie from LG for this device. They're terrible for updates
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] scorpio76r:
I agree with you completely. I can't really use RR because I broke it a few times with the majisk and, xposed combo. With lineage, I haven't had that problem and, run both majisk and, xposed modules together without bootloops unlike on RR.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] :
VoLTE not working, you mean the LTE connection does not work? Some phones display VoLTE and some do LTE only. Does the VoLTE involve both phone communications through the large bw of LTE and data? And hence LTE meaning that only data go through LTE and phone comm goes through the usual 3G or 2G bw? What about the IR blaster?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
You can get a different second screen affect by using the non second screen ROM and flash the gamma kennel that supports second screen (v71SS). It moves the nav bar to the second screen area. I've been using that for a few days. It works very well. Even YouTube video plays full screen.

Thank you for taking the time. In case it's useful to someone in the future, it's post #2521.

What I did:

1) I followed the instructions from runningn4ked's thread and installed TWRP 3.2.1 into LAF

partition.

https://xdaforums.com/v20/how-to/root-lafsploit-h918-version-t3773443

2) I used TWRP 3.2.1 to install TWRP 3.2.3-4 into recovery partition.

https://xdaforums.com/v20/development/recovery-twrp-3-2-1-0-t3720239

3) I used TWRP 3.2.3-4 (recovery partition) to do a backup (IMPORTANT!) :)

4) I went to lineageOS.org and downloaded OFFICIAL, latest nightly-14.1 & addon-su.

5) I copied the 2 zip files to external SD card in my phone.

6) I used TWRP 3.2.3-4 (recovery) to install OFFICIAL 14.1 & addon-su, following the instructions in lineageOS.org. I was unable to boot. It gave me a blank screen after LG screen. According to post #2623 in this thread, it was never going to work. Can't use 14.1 once your phone has tripped ARB1.

5) I booted to recovery & restored 10p ROM from the backup in step 3. I rebooted to stock ROM to verify.

6) I downloaded UNOFFICIAL "lineage-15.1-20181214-X86CPU-h918-10p" from link in first post.

7) I downloaded "Magisk-v18.0.zip" using that thread to find the link.

https://xdaforums.com/apps/magisk/mod-magisk-v1-universal-systemless-t3432382

8) I copied the 2 zip files into external SD card.

9) Using TWRP 3.2.3-4, I installed the UNOFFICIAL 15.1 zip. I wiped both caches.

installed Magisk zip. I booted to system.

10) It took about 1 minute to boot to lineageOS 15.1.

TODO) Sometime today, I will boot to recovery and do a backup of this install.

If anyone needs more detail, I'll be happy to provide it.

Am I right in assuming I should thank the following?

This is exactly what I did also. I just personally want to thank you for your contribution because when I came to lineage from the alpha rom after lg pulled the plug, I was a little lost on how to flash this rom. Anyone who is new would profit from your post.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Grin59:
Also to note, my H918 had ARB1 and will never work with LOS 14.1. I can't remember if the H918 is the only one that can get ARB1 but I do know LOS 14.1 won't work with a device with ARB1. So if you're in the same position as me, just flash the latest LOS 15.1

This rom rocks, except that sometimes the phone won't connect to saved wifi (like my home wifi) when I get back home from outside. Forcing the wifi on or off won't work, and the only way to connect to my home wifi is to restart the phone.

This is the same with my office wifi too.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] txenglan:
I did this in an attempt to fix the fingerprint reader on my US996. It completely hosed the phone and turned it into a brick. This forced me to spend an entire day going through the unbrick method as posted over here I advise extreme caution if anyone attempts to flash whatever is in this zip.

Which variant are you using?

Incidentally, I've tried to flash back to pure stock using LGUP/Uppercut but it refuses to recognize my phone. I also spent hours trying to sort this out (using about 10 different methods mentioned elsewhere in this forum) but I haven't found a way around it. I'd appreciate if someone (Redline perhaps) could explain exactly what it is about flashing any stock Oreo/variants that causes the fingerprint reader to stop working if installing Lineage. I'm still learning and I'm intrigued by what stock "leaves behind" when moving to other ROMs.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
I don't know what exactly flashing stock Oreo breaks, but one or two of our notable devs at the very least have mentioned the bootstack.

Flashing a stock ROM using LGUP or KDZWriter writes or allows you to write to areas that flashing something like LineageOS doesn't.

These areas include /modem for example, which is why one or two people fixed the dialler delay problem by manually updating /modem from the latest non-20a KDZs for their variants.

It more than likely includes other areas that emdroidle talked about in a recent post in his KDZWriter thread.

It's more than likely, if I had to guess, that stock Oreo updates something somewhere that LineageOS 16.0 doesn't touch. And that whatever it updates gets broken by using LineageOS and not stock (could be something as simple as a symlink to a file somewhere that exists on stock but not LineageOS).

If this is true, then what's "broken" in an area that LineageOS won't write to gets "left behind" in the sense when you wipe stock and flash LineageOS. Even though it's not actually "left behind" because it's meant to be there.

The reason I think this is mainly because of which partitions LineageOS or even ResurrectionRemix write to when being flashed, and the fact that pre-v20x KDZs can be used to update /modem without issues. Using a v20x modem currently causes kernel crashes.

Hopefully, it's all just a matter of waiting for the devs to work out where everything is, and relocate it to somewhere LineageOS can work with. Being able to have all the firmware and such in /vendor would help, rather than having it all spread out everywhere and needing to keep track of it.
