IR blaster works on my H910A after installing Gamma kernel 3.0. That was the only version I could find aside from 20.0 (which is for LOS 18.0 and didn't run right on my phone with LOS 17) since the Gamma kernel download page links are dead.

IR blaster wouldn't work for me with the stock LOS 17.1 kernel.
[LG V20 Guides, News, & Discussion] DonVasaschi:
Okay, thanks. I am having some doubts about flashing the gamma kernel because I have magisk 20.4 on the phone now (it appeared to have auto updated some point yesterday). I would like to know can I go ahead and flash the gamma kernel 3.0 and not encounter any booting problems also would I have to flash the thermal and audio mods? And if so could you possibly share the order in which i should do it, it will be much appreciated. I will spend some time today finding the files but I won't flash anything until I hear back from you or someone else that have done it based on how my phone is currently setup.
[LG V20 Guides, News, & Discussion] partyman66:
Make a TWRP backup of your boot partition before putting gamma kernel in. You can always roll back to stock kernel by restoring just that partition and wiping cache if something goes wrong or you don't like it.

The gamma kernel install is as straight forward as it comes. Boot into TWRP and just flash the flashable gamma kernel zip file that's the correct one for your v20 model. It doesn't matter if you flash it from internal storage or SD card.

As I mentioned earlier, I'm using Gamma 3.0 because that's the only one I could find that's compatible with LOS 17. I tried using version 20.0 which is for LOS 18 and my system ran all choppy and generally like crap so I switched to 3.0 and it's fine except that I noticed the KSMD process taking up a bit of CPU almost constantly while my screen is on, so I manually disable it by going to /sys/kernel/mm/ksm/run and changing the 1 to a 0. This can be automated with a startup script or even set to automatically apply with a kernel manager app on startup. They really need to fix the downloads section for Gamma kernel, because there are many versions newer than 3.0 that supposedly have improvements and bug fixes all the way up to version 10.0, but nobody seems to have those other gamma kernel versions available anywhere that i could find.

If for some reason you don't have working root after the kernel install, boot back into TWRP and flash Magisk again. The Magisk stuff is tied into your boot image (kernel), so I've found I usually need to reinstall it after restoring an old kernel.

Also flash the modded stock thermal engine config after the kernel from TWRP. I think there are just 2 files in the package, and i found where the originals were on my system and made backups of them just in case i didn't like it so i could go back, but nobody ever goes back on those... just me being cautious.

I'd also recommend staying with the Magisk version you are currently using. Don't upgrade to the new version. Magisk started blocking root apps that it arbitrarily thinks aren't worthy of root in the later versions which made it so that I couldn't use ES File Explorer anymore as root(old safe version of it). I don't like that and just want root manager to be simple and do what it's told.
[LG V20 Guides, News, & Discussion] DonVasaschi:
Thanks for the reply bro, I've been holding out waiting in your reply, i will definitely try it when I get off work in the next 6 or so hours. I will inform you how it goes.

UPDATE

I've returned with positive news. The ir blaster is now working. Along with flashing the thermal file and editing the file you suggested everything is fantastic. It's a minor issue but I currently have to install 3 different camera app on the phone. In one the selfie is blurry, in the other the selfie is super sharp and the stock lineage camera app records audio low (tested the back camera and not the selfie camera) is it possible to just install an audio mod just for boosting the audio when recording or could there be a flashible zip that tells the microphone to record on a higher decibels than normal so as the playback in the video may seem normal (hopefully not too baffling). Let me know if that is something that could work (theoretically yes but in reality???)
[LG V20 Guides, News, & Discussion] rsr911:
I was on stock rooted Oreo with TWRP and installed LineageOS 17.1, nanodroid and magisk. Working fine but fingerprints (at least) don't work.

As I understand it I need to use LGUP to flash back to nougat, then install LineageOS to get the fingerprints to work.

Can anyone confirm that and will I lose TWRP when downgrading to nougat?

If I lose TWRP then I assume I use the dirtysanta method to get TWRP back and then flash Lineage like I did before. Is that correct.

Sorry just a little confused after reading all 58 pages in this thread.
[LG V20 Guides, News, & Discussion] partyman66:
You'll lose TWRP if you go back to Nougat since you have to do it by KDZ. Just re-root with filthy Santa, install the right firmware files for your device from TWRP (unless the KDZ was the right one for your device... Meaning not an H910A), and then do lineage install. I did the 15.1, 16, 17 progression of lineage so I could make sure my fingerprint sensor and various other devices worked after each install (did a factory reset after each one).
[LG V20 Guides, News, & Discussion] partyman66:
I also ran into a bunch of issues with every Camera that I've tried on this Rom. They all pretty much crash on occasion (even the one that comes with the ROM). As you mentioned, the stock camera that comes with it takes unuseably blurry selfie pics. I tried various GCam ports with various configs and none of them could do a combination of front cam, selfie cam, video and audio recording successfully. The one that I found which did all of them is TRCamera. I'm using TRCamera and currently bouncing back and forth between Maciek and Diablo configs. Weird thing though..... all of a sudden my selfie cam on the stock camera now shoots clear shots in the past few days instead of those blurry ones. I don't get it. It seems like me messing around with GCam and TRCam settings somehow kicked my stock Lineage camera into now working for selfies, which is nice since that seems to be the most stable of the bunch despite not necessarily having the most features or having much for customizable options.
[LG V20 Guides, News, & Discussion] BloodyIron:
I really hope the Friday release fixes Exchange Services on my device, because if not, I'm going to wipe and re-flash from two weeks ago and not update for a while. :/
[LG V20 Guides, News, & Discussion] DonVasaschi:
Yes. It sucks but that's the price we pay as testers. Could you somehow send me the exact settings you're currently using for trcamera and GCam. I'd like to see if I can possibly improve on those while also wishing that my stock lineage camera starts to take selfies better.

Also in-between those three camera has the audio after recording a video increase or is it still low?
[LG V20 Guides, News, & Discussion] rsr911:
Thanks much! I kinda figured.

What I did was flash H91810p using Uppercut after I made sure I had all the LGUP drivers, dll, and program installed. That got me back to nougat stock.

Then I used FWUL inside a virtual machine (I have a persistent version) and ran RunningNak3d's TWRP scripts, step 1 and step 2. That got me TWRP which I then used to flash to the newest TWRP.

From there I flashed LineageOS, Magisk, and Nanodroid GAPPs. Its working great!

My goal was a degoogled phone and that's what I have now. When I tried to install on Oreo fingerprints didn't work but they work fine now!

Now I just gotta figure LineageOS out. I have a few banking apps I need that I can't find apk files for. Looks like I can just use Aurora store to get them from Play anonymously.

I must have had a brain cramp earlier. Like duh! Of course flashing back to stock nougat kdz would wipe out TWRP lol. But it never hurts to ask. Only reason I didn't use dirty Santa is I've never used it before but I have used FWUL. Just gotta make sure you have the right kdz to work with the script.

Anyway again, much thanks! I'll have to find a lineage forum or thread as well as nanodroid so I can learn the ins and outs and keep big tech from spying on me.
[LG V20 Guides, News, & Discussion] partyman66:
You can get official safe versions of banking app apks by installing the app from the Play store on an Android Emulator like Knox and then finding the APK in /Data/app on the Emulator and copying it off to your phone. Kind of a pain to do if they regularly update it though.
[LG V20 Guides, News, & Discussion] Lokmane Deve:
Is there any stock pie rom for this model (H918)???
[LG V20 Guides, News, & Discussion] BloodyIron:
Updated to daily that rolled out yesterday. Did not properly solve the Exchange Services issue. Going to wipe device clean and re-flash to two weeks ago and not update for a while. Really annoyed the updating ecosystem breaks things like this. Punishing me for wanting to stay secure and updated.
[LG V20 Guides, News, & Discussion] Jesus is God Almighty:
What TWRP 3.5.0 Should I use for my V20 F800K model?
[LG V20 Guides, News, & Discussion] rsr911:
That would work. Then I could fire it up from time to time and let it update and grab the new apk files.

Anything wrong with just using Aurora store though?
[LG V20 Guides, News, & Discussion] rsr911:
Where are you finding TRCam?
[LG V20 Guides, News, & Discussion] partyman66:
I have never used it. Just with banking apps you want to be extra careful where you get them.
[LG V20 Guides, News, & Discussion] Jesus is God Almighty:
Disgusting... That is absolutly unacceptable. So they are now deciding which apps deserves or does not deserve root?
[LG V20 Guides, News, & Discussion] partyman66:
It seems so. I'm sure it's of noble intent so that people don't install untrustworthy apps with root permissions, but I'm of the opinion that once you root your device the responsibility to act as warden of your root apps should fall on us and not have it decided for us by the root manager's programming.
[LG V20 Guides, News, & Discussion] nexus5+user:
Howdy there,

Do you have an update on the case please good sir?

Thank you kindly & Bless
[LG V20 Guides, News, & Discussion] BloodyIron:
Yeah I really want my flip cover case thinggy to work again :( switching to LineageOS 17.1 from stock LG v20 ROM 7.1.1, I notice its absence immediately! I use the feature exhaustively, so I'm hoping I can find a way to get it back.
[LG V20 Guides, News, & Discussion] Jesus is God Almighty:
Amayn to that! Absolutely agreed on that, we the users should have the power, not being decided by foreign bullshitters who just wanna push more control. They do it on every level these days in our world.
[LG V20 Guides, News, & Discussion] Chucknorris1975:
Has anyone else had this issue? On the last 2 nightlies I flashed for the H990DS I ended up in a boot loop. Loading LOS for several minutes and back to TWRP. I ended up having to do a FULL wipe (data system cache etc) and re flash an earlier nightly to get it to work. I'm currently on 3rd Jan 2021 nightly and am too nervous to try flashing the current 31st Jan 2021 nightly. Magisk is up to date.
[LG V20 Guides, News, & Discussion] hungtinglung:
dirty update from Jan 24th nightly-h990.

no problem.

wipe cache/dalvik everystep.

lineage-17.1-20210131-nightly-h990-signed.zip

gamma kernel

magisk 21.4
[LG V20 Guides, News, & Discussion] BloodyIron:
I didn't have the same issues, but I had issues with the last two nightlies breaking Exchange Services. I completely wiped and went back to a nightly at the beginning of January, as Exchange Services was 100% useless.

I really hope updates in the future aren't like this, because this really motivates me to NOT update, ever. Defeating the point.
[LG V20 Guides, News, & Discussion] G U C C I:
Have you considered LOS 18.1 to see how it works with Exchange Services? It may have been fixed in Android 11. We have an unofficial build from @aleasto that you can try.
[LG V20 Guides, News, & Discussion] aleasto:
Exchange is fixed again in the next rolling release.

Unfortunately the email app is very much outdated and will almost surely be dropped in 18.1
[LG V20 Guides, News, & Discussion] BloodyIron:
Hi Aleasto,

Next rolling release, as in Feb 4 2021?

Will EAS still work in 18.1 just in a different way?

Thanks for the insights here!
[LG V20 Guides, News, & Discussion] BloodyIron:
I really am hesitant to try beta code on my daily driver, it has a time cost involved. I don't mind moving forward, but I'm cautious at this point.
[LG V20 Guides, News, & Discussion] G U C C I:
It's not really all that beta, just a few minor issues. I run it as my daily and it's fine for my needs at least; although I don't require Exchange Services...
[LG V20 Guides, News, & Discussion] BloodyIron:
I run about 4-5 EAS accounts at any one time that I need to keep up with, so it really is rather important to me. That being said, how soon before LineageOS 18.x goes RELEASE status?
[LG V20 Guides, News, & Discussion] G U C C I:
Probably not for awhile as @aleasto is the one who makes the UNofficial builds for it and while I make my own, it's still not as stable as 17.1. 16.0 is the most stable in my opinion but obviously it's the oldest of the bunch.
[LG V20 Guides, News, & Discussion] Chucknorris1975:
Where can I find gamma kernel?
[LG V20 Guides, News, & Discussion] G U C C I:
Which variant?
[LG V20 Guides, News, & Discussion] Chucknorris1975:
For V20 H990DS running LOS 17.1
[LG V20 Guides, News, & Discussion] hungtinglung:
flashable-h990-gamma-kernel-v20.0.0.

use smartpack-kernel manager to control the kernel.
[LG V20 Guides, News, & Discussion] aleasto:
The date depends on your variant.

You'll need a third party app for sync and email.
[LG V20 Guides, News, & Discussion] zeroderp:
will some one PLEAS make these 15, and 18 LOS downloads available with out google PLEAS!

after the pain of going to another persons house and using their micr0$oft system instead of my home linux & firefox,,, i FINALLY got 17 downloaded from the lineage site,,,but i still have absolutely NO way to download anything i need of the android 8,,,or lineage 18.1

yall is KILLIN a brother !!!!!!!

been a lurker here about 10 years. yall hurt me so bad wit this google spyware embedded into xda. took me till now in such a desperate position to finally make a log in user name so i could beg for a way i can download what i need to flash my phones..

on a micr0$oft machine,,verified by google. so shameful.
[LG V20 Guides, News, & Discussion] BloodyIron:
Wait, so EAS and E-Mail just won't be included in LineageOS 18.1 out of the box??? What madness is this? (Why?) And what app should I use instead?
[LG V20 Guides, News, & Discussion] partyman66:
I couldn't get kernel version 20.0 to run right with LOS 17.1 on my h910A. IIRC this version was built for LOS 18 not 17. Mine runs fine on gamma 3.0.0 when installed on the same Lineage 17.1 installation with 3.0 dirty installed over Gamma kernel 20.0 after 20.0 was slow and choppy.

Got it to work on h910 coming from rooted oreo. everything seems to be working fine.

So let me explain one of the issues I had, that was the camera not working but I found a fix. let me explain my installation process for anyone interested

1)boot into twrp (im using phoenix recovery-twrp-h910-2019-10-25)

2)wipe>advanced wipe> select data/cache/ and dalvik cahce/

3)go back to wipe and format data, it should be around there in the wipe options.

4)I then Flashed the latest oficcial LineageOS 17.1 for my h910 and then wiped dalvik/cache

5)I then flashed gamma kernel v20.0.0 for the h19 > then flashed the v20 tasha xml patch> then the stock thermal engine mod. (all files can be found in the official gamma kernel thread)

6)Then i flashed magisk v20.4 and wiped cache and dalvik cache

7) Then i reeboted into system thinking it was all done good to go but ran into the issue that neither the camera nor the finger print sensor worked. I looked into the thread and found
[LG V20 Guides, News, & Discussion] serpent android:
Will flash it and see.scared a bit but hoping all goes well dude
[LG V20 Guides, News, & Discussion] Landloord:
Just follow the guides, the worst you can get is a bootloop which is very unlikely.

Do u use gamma kernel and if yes can u please send the latest link..heard ir suppirts the Dac
[LG V20 Guides, News, & Discussion] stevenjus:
I just installed last night and coming from rooted oreo all I can say is the experience seems to be better. honestly I havent given it as much use as i had with rooted oreo but the setting options and control lineage offers is so much better than stock oreo that its worth it. I do believe its smoother than stock tho/ less warm and snappier. og launcher sucks tho so im ussing kiss launcher

I use gamma kernel but dont see any option for the dac like there was on stock
[LG V20 Guides, News, & Discussion] YesofCourse:
f800 when ?
[LG V20 Guides, News, & Discussion] Landloord:
I'm currently using no custom kernel. Lineage's own is just fine.
[LG V20 Guides, News, & Discussion] stevenjus:
Hey you seem to know a lot about this, one question. If i later on would like to update to a more stable linage, how would the process go? im on the latest official.
[LG V20 Guides, News, & Discussion] Mysticblaze347:
I'm in same boat. Guides say nothing for ARB. I'm scared to try because I am not sure if this will work for Sprint. Sprint stock after ZVD was not rootable. If I can easily swap from this 17.1 and stock 7.0 then I should be fine, but not knowing for ARB is holding me back.

I'm sure this don't have ARB and would work fine, but no one has answerd my last question.- Not that I am saying you have to lol.
[LG V20 Guides, News, & Discussion] stevenjus:
from stock oreo straight into lineage, no prior lineage before. I have decided to flash again and try the latest unoficial but with out gamma kernel. the reason? it has been working very sluggish so far. web browsing/browsing the reddit app/ or clover(4chan app) is much slower than it was in stock oreo.
[LG V20 Guides, News, & Discussion] Landloord:
Lineage requires a stock nougat base, not Oreo, if I'm reading right
[LG V20 Guides, News, & Discussion] stingbandel:
Alright so u can get the camera to work from stock oreo but not able to get the fingerprint to work. To make them all work, it has to be from nougat. Thanks for the info…

I'm on an H918 (I know, not the same) and I'm running Gamma Kernel v20.0.0 just fine. Curious not the same for you.
[LG V20 Guides, News, & Discussion] partyman66:
Yeah.. I'm not sure why it ran so poorly with 20.0 on my phone. Does 20.0 still do the massively delayed notification from when you unug a charging cable from the phone? Sometimes I have like a 1 minute delay on that notification with gamma kernel that wasn't there with the original LOS kernel.
[LG V20 Guides, News, & Discussion] xxseva44:
I have the same issue with gamma v.20 on my vs995 although other than that gamma makes my phone so much better to use. Are you running the thermal fix too or just gamma?

okay pretty new and unlearned on this, but does this version run on the V20 F800K version?

Strange, i've only had issues similar to yours when i didn't use the thermal profiles
[LG V20 Guides, News, & Discussion] partyman66:
I just put Gamma kernel 20.0 back on my phone last night just to give it one more shot and it seems to be running fine now strangely. I wonder if some sort of fluke partial corruption occurred the first time when I installed it, installed Magisk, and the thermal profiles? It's a night and day difference between this install and the prior one.

Anyone else have the issue where video recorded on the camera has no sound? I recorded at an event and when I got home and tried watching I was disappointed to find that there was no audio.

Using Google Camera Urnyx version 7.3.018.291816413. Every other camera I've tried kept crashing.
[LG V20 Guides, News, & Discussion] Chucknorris1975:
This kernel as well as v3.0.0 made my phone laggy as hell. Notifications took forever to come through. When I plug my phone to charge or take it off charge, it would take almost a minute for the notification to come through that it charging or came off the charger. Apps were laggy, especially the camera. 🤷
[LG V20 Guides, News, & Discussion] partyman66:
Did you install the modified stock thermal engine files with it? I think you need that to get everything running smooth with Gamma kernel.
[LG V20 Guides, News, & Discussion] Chucknorris1975:

[LG V20 Guides, News, & Discussion] Chucknorris1975:
Do I flash that in twrp?
[LG V20 Guides, News, & Discussion] partyman66:
Yeah, you flash in TWRP. You can save the original files if you want, should you ever decide to revert back to stock. Make sure you're comfortable in using the TWRP file manager or TWRP command line to do the file copy should you ever want to revert though. I wouldn't recommend trying it with a running system.

I tracked them down as these:

/system/vendor/bin/thermal-engine

/system/vendor/etc/thermal-engine.conf

It's possible that the originals are included in the flashable as well, but i'm not certain of that.

BT been stable (from what i read) for a hot minute.

* from what i hear * everything i need for my daily is long ago worked out and stable for a very long time on both. i just do not ask for much is why.

once i get my other 2 v20 working i hope to have one running 17, and one running 18.

if the Lord be willing. then maybe i might learn after that how to be useful to the community here.
