When I was about to start installing LOS16,17 - 18 having downgraded to Nougat and rooted; I asked if/why I needed to install 16 and 17 before installing 18 and Aleasto (The dev of this ROM) said I didn't need to - said I could install 18 directly. So far the ROM is working really well and I have reliable finger print scanner: only thing is lockscreen gestures currently not working, which I think others have mentioned too. And of course there are things still to be added.

As I am less experienced than others I am happy if others have differing opinion to contribute. However so far it seems more that people are doing the step by step upgrade, simply because someone else did it that way and they know it works.

I have yet to see any explanation of why you would need to flash the in between versions, especialy if you are clean flashing; as I believe you should between different version numbers.

Maybe could be a good idea to put a warning about Gamma not being the best choice/ready for this ROM on the original post?

Just sharing that I've just made an experiment in downgrading from rooted Oreo H990DS to Super ROM 4.1 before flashing the Lineage 18.1 Dec 13 build. Everything seems to be working, however fingerprint sensor does not work. It seems we need to fully downgrade using KDZ file to Nougat before upgrading to LOS 18.1 in order to make the fingerprint sensor working.

Thanks a lot @aleasto for this beautiful ROM!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hamid_valad:
Thanks for sharing your experience.

the problem is that i'm on a mac now and i can not use lgup or other utilities for root!

I think i have to go to a friend for downgrade and root. and other problem is that i have no idea how to root again. i read the topic and i don't know how i did it in the first place. thanks my friend Reza form xda that guided me back then to root.

another thing. if i downgrade to android 7 i believe it will wipe my internal storage too. thats another issue.when changing roms, internal storage remains intact, but KDZ wipes it too if i remember correctly.

does anyone have a backup for a rooted stock android 7?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] SammyKitkat792:
Heyyy buddy!!! You can use Alpha Omega Nougat Custom Rom which is based on LG Stock nougat rom!! It will solve the problem! I've did the same!

that would be great. can you give me a link? i read the post. but the link is not working.

also i'm on h990ds. i cant find any android7 rom for it. :(
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] slaxer:
Just like I've shared in the several posts before. I've tried to downgrade H990DS from rooted oreo to nougat, using H990DS SuperROM 4.1 ROM. It went successfully. However the fingerprint scanner did not work after downgrading, it does not work both in SuperROM 4.1 based on nougat as well as LOS 18.1. I think something is missing eventhough I have successfully downgraded to nougat using SuperROM zip. We should use the KDZ file to downgrade or if someone still having the downgrade.zip file that @jl10101 shared before in other thread, please share it here? I can test it since I have more than one V20 H990DS that I can play with.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hamid_valad:
I think super rom is based on LOS and not based on stock rom. thats why it is not working. (haven't used it before, thats what I think)

I cant find any rom or working link for stock android 7 based rom for H990DS. neither the "downgrade.zip" that you mentioned nor the "Alpha Omega" that SammyKitkat792 mentioned.

if you decide to downgrade using kdz and root afterwards, can you please make a backup zip file for me so i can restore it on my phone and go to rooted stock android 7? pleeease! :( it would mean a lot to me.

nothing works on MAC :((
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] slaxer:
I think the SuperROM is based on stock nougat. However, when we update to Oreo, some files are being replaced and rewritten by LG. That's why when we upgrade to LOS from Oreo, some of the functions (i.e. fingerprint sensor) is/are not working as is should be (and I've heard that LOS in V20 is developed using V20 nougat as its development base).

Anyway, I've tried to downgrade using LGUP and H990DS 10b KDZ, but has no luck. It can't be detected by LGUP. I've tried copying the LGUP_common.dll and replacing the LGUP.exe, but still no luck. Reverting back to the old Oreo stock TWRP backup also gives me error on /system partition not being mounted. Lucky I can still access TWRP.

Edit: I think I've lost Download Mode :( I can only access fastboot. I think that's why I couldn't revert back to stock as my PC does not detect any COM Port related to V20.

oh my!

getting really frustrated!

I went back to android 7 with kdz. phone would not boot. long story short after a day of constant struggle, i got my phone back with lg bridge.

then i used dirty santa to root and then installed this rom. i had only one problem and that was the pre-boot logo. every thing else was fine until i wanted to use my bank app. it said it wont work because i am rooted! i opened magisk to use hide and changing package. but the change package was grayed out! i used the app to reinstall, did not work and after that the app said no root! i went to twrp to reinstall it. it said can not mount /vendor. tried different magisk and twrp versions. non worked!!!! i had it installed and i had root access. but it is gone out of the blue. can any one help on how to solve this issue?

bank app says you have root

magisk says you dont!

:(
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] G U C C I:
Some banking apps have other safeguards in place and can detect a modified device even if you use Magiskhide.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hamid_valad:
thats not the problem now. and i know how my banking app works because i had it for years on my rooted phone.

the problem is:

magisk manager app says magisk is not available!!

when i go to twrp to install it, installation fails.

error:

can not mount /vendor!

latest twrp and latest magisk + some other versions. all have the same problem.

edit: root checker says root is not properly installed on this device!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] G U C C I:
Which version of Magisk are you using?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ezzony:
Firstly, I thought I would try this out and I have to say I'm really impressed! I haven't used non-stock for a long time on any device but I'm tempted to stay on it. But I need to sort out some issues first.

Camera and fingerprint don't work. I downgraded the partitions to nougat AFTER I installed LineageOS. Would that be the reason for this?

A minor bug is my data disconnects, not often. I looked at the APN settings for my carrier and found that it had been deselected, so I just reselected it and it came back. This has happened twice in the last 24 hours.

All my essential mods are working including V4A, JamesDSP, and Xposed edge pro which required Edxposed. Nice. BTW, does anyone know hot to induce full immersive mode or just for the Nav bar? SystemUI tuner won't do it on 11.

Is there anything else to do with Quad dac? I see an app for QuadDac tile but I don't see the tile but maybe I didn't look hard enough as I'm just getting used to the new layout. It sounds good but it just doesn't seem to go as loud as on stock. I recall there was some additional stuff to do on previous LineageOS roms to get it working like stock or is that done already in this rom.*

Is it the case there is no way to fix the static screen in the kernel? I'm be prepared to have a look at it when I've time, but I'd need some direction to get up and running with it first. I suppose it's a modified LG kernel with bits taken out and ramdisk modified?

*Edit: I found the Hi-Fi toggle, pretty cool. Edit tiles is on the left and not the cog on the right.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ottafish:
Sadly, I'm noticing some dropouts in bluetooth connections now and echo on voice calls.

Echo on voice calls seems to happen after about 10 mins on a call. I just blame the service provider ;)

Also, BT is starting to become flakey again. Seems it's random on dropouts when connected to my car or headset.

Doesn't seem to effect calls as much as streaming music.

I'm just working around it for the moment by using the 3.5mm audio out plug.

But Los16 which I still have on one of my other H990DS is the most stable and useable of all of the releases I've used.

I'm starting to wonder if it's time to retire the V20, (sad day indeed) and move to newer hardware ..

As much as I love my V20's, there's a few small, niggling issues that start to add up. Some things I can put up with, some become like a small splinter, annoying but livable.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hamid_valad:
Fixed

workaround:

extracted boot.img from rom file. and put on my phone

opened magisk, it has an option to patch boot file. so i patched my boot file. (new file name: patched.img)

went to TWRP and flashed patched.img.

reboot.

done.

camera is not working at all???

for finger print, I went from stock oreo to LOS 18.1 and it did not work.

so I installed stock nougat with .kdz file. after setting up first boot, i started rooting. after root finished (and a lot of issues and errors in between since i did not remember how things were and i had to do things multiple times!) i installed LOS 18.1 and fingerprint is working.

did not notice APN issue since i'm mostly on wifi.

I could not get full screen mode either. (also i could not install xposed! thats how old my knowledge is! what is v4a and jamesdsp?!?! )

for screen burn-in (if I understood your problem right) there is an option in settings.

open settings --> display --> livedisplay

what i used:

color calibration: every thing 85 percent

picture adjustment: intensity 30 (others)

i also use darkmode all the time.

hope it helps.

Is it possibile to decrypt a phone with Los 18, before an upgrade?

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ezzony:
I downgraded to nougat and started all over again. Fingerprint now works fine but Camera still no work.

Yeah some say to reduce live display to 90% each, but you say 85. No harm in experimenting I suppose. I think 90% wasn't enough.

So not sure what I can do about the camera now. I tried the earlier version in case it was a bug in the latest version but still no camera after downgrading and fresh install.

Edit: I'm on VS995 is that is relevant.

Of course
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] sonar77:
Great! I hope so, because 17.1 (encrypted and Magisk rooted) crashes on updating
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] aleasto:
Magisk cannot reinstall itself after an OTA if the device is FDE encrypted. You'll need to manually flash magisk every time (though you must have something bad for system to crash when magisk is not installed)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] sonar77:
Thanks again. So: should i uninstall Magisk before upgrading? Does Los 18 have OTA upgrading?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] aleasto:
Magisk will be uninstalled automatically. If you have modules that break without, then perhaps you should.

Thanks again! Now I'm ready to install your ROM. By now I have rooted Oreo: should I revert to stock Noutgat or is there a Noutgat custom Rom?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] slaxer:
Revert to stock nougat by flashing the appropriate .kdz file using LGUP if you want to have a working fingerprint sensor before flashing LOS. There is a stock nougat custom stock rom, such as super rom, however from my own experience flashing the nougat custom stock rom from rooted oreo does not make the fingerprint sensor work properly.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] sonar77:
To upgrade version, should I use a dirty flash?

Yes, everything works fine. On his builds and my own personal ones...they both work!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Merazomo:
Thank you for that. Aside from the usual installation of the ROM (lineage-18.1-20201213-UNOFFICIAL-h910) after going back to Nougat, GAPPS (NikGapps-basic-arm64-11-20201214-signed), TWRP (twrp-3.4.0-1-h910), Magisk (Magisk-v21.0), etc. Are the Vulkan drivers also recommended? What's with the [R] and [M] on the GPU driver's name? Is the R for recovery and the M for magisk? Sorry, I've never installed drivers on my V20.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hamid_valad:
after a while using this rom, this is my experience:

things are smooth and working fine most of the time.

there are glitches though:

I have black screen crash, from time to time. (based on usage, once or twice a day.)

safety net is not passed.

camera or camera related apps (even whatsapp video call) crash some times and after a few seconds if you run the app again they start working. this crash happens mostly when switching between cameras

navigation bar is another issue. if you want to use gestures, you HAVE TO use the default gesture settings.

if you want to use 3rd party apps, the navigation bar will not hide. no immersive mode.

quick settings grid is 3x2. and you can not change it.

and there are negative points for android-r.

like not much magisk or edxposed modules working.

no official opengapps.

some apps not supporting it.

and things like that.

i dont know about first issues, but if android 11 issues bother you, i suggest using lineageos 17.1

(also the quick settings grid is bigger in LOS 17.1)

I hope my short experience helps.

edit: can I go from LOS 18.1 to official LOS 17.1 without loosing my apps and having to install them and setting them up again all one by one, to see if above issues can be fixed there?

edit: there is no one hand mode (or single hand mode) either. :(
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ottafish:
I also have the camera crash when using apps. I basically have to kill the apps and start again. It's random when it happens.

Also Bluetooth is a bit hit and miss. ( but way better than 17.1 which BT is mostly useless) but still nowhere near stable as stock.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hamid_valad:
Well I don't miss stock oreo with awful kernel AT ALL

its faster, lighter, more customizations, less lags, less bloatware, and ... (I think less battery consumption)

I can name a few things to be added or tweaked. like one hand mode or quick settings grid size.

EdXposed, OpenGapps and other not compatible apps with android 11 has nothing to do with this rom or awesome developers.

ps. I dont use camera that much and 5sec for a camera crash is much more tolerable for me than a day long slow mode!!!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ottafish:
I agree totally. It's the best the phone has been, both speed and modern usability. It's a great upgrade. If we could nail BT down, it'd be perfect.
