Okay so out of curiosity i flashed gamma kernel and it's themal fix and with gamma, it found it's location within a couple of seconds and stayed locked whereas with the stock kernel, after 10 minutes it still couldn't figure out it's location. This issue seems to be an issue with the stock kernel. I would keep gamma but it does not run smooth at all on 18.1 so i guess i'll just have to sick with the stock kernel. What variant of the v20 do you use? i use the vs995
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] e-thug:
Fingerprint scanner not working on clean flash. Anyone have this working on VS995?

Using lineage-18.1-20210104-UNOFFICIAL-vs995
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Works fine on my vs995, assuming u started with the original android 7 kdz, your supposed flash lineage 15.1, 16, 17.1 and then 18.1
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] e-thug:
Wish that was mentioned in the OP. Now that I've lost TWRP, how would I go about doing it in that order?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Was twrp replaced by the lineage recovery? if so, the next time you set up lineage os make sure you disable the option to flash the lineage recovery. To flash twrp, Connect your phone to a pc and and install the adb platform tools. Once you have that, go into a command window (if you dont see the option to open a command window, press the windows key and R and type "cmd" and it will open a command window) and type adb devices, (if it doesn't work navigate to where you installed the adb platform tools by typing cd and the folder it's in) you should see a window on your phone pop up and ask you to enable debugging, from there type "adb reboot bootloader" and you should see your phone start vibrating. From there type: fastboot flash recovery (location of recovery image ie: c:\recovery.img) Dont include the brackets. Once your done type: "fastboot reboot" And once you have twrp back, simply get the different versions of lineage os for your variant and flash away!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] e-thug:
Right, but I was more interested in flashing incrementally. Coming from a rooted 20c Oreo ROM (Alpha Omega)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Since your coming from oreo you'll have to go back to the nougat kdz which is 13A or below, you'd have to use lgup. Although a shortcut i found was that if you made a twrp backup from when you had the 13a kdz, you can flash it and then flash the new roms and your fingerprint should work. One that's done, flash 15.1, 16, 17.1 and then 18.1 one after another. If you have a vs995 i can send my nougat backup
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] TripOG:
I don't think I am seeing that issue on the latest build using the kernel that comes with it on waze or Google maps. Maybe I am though, how long is forever? I seem to get a lock within a few seconds.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Dang that's fast, during my testing i did with the stock kernel and gamma, after roughly 5min mins i got a lock but after a while it loses it's lock. Gamma got a lock almost instantly and stays locked. I wonder if this issue only affects the vs995 and possibly the us996 since they use the same hardware and stuff. @aleasto
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ottafish:
Mine's the H990DS version. I tried Gamma kernel and it became sluggish, hot and would lock up. I ended reverting back to the stock 18.1 kernel. It's really weird, sometimes it'll take forever, (6+ mins) to get a lock. Other times it isn't an issue. But sitting on the side of the road on my motorbike, waiting for a gps lock with my girlfriend on the back has led to some frustrations.

Some of the 2fa we need for work won't run on anything under pie (9), and oem firmware stopped before that. It's such a shame that I'm starting to consider moving to a new phone. I love my V20, but it's starting to become less stable as time and firmware progress.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
I'd probably use the rr7 rom in your case, It's the most stable rom i've used on this phone and from what i remember it doesn't have this gps issue. RR7 Another bonus is the customization options for the rom. I'd recommend flashing gamma and it's thermal mod with RR7

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] TripOG:
Oh dang, yeah mine is no where near that slow. I did have an issue with google maps crashing a little while back because of a change made with gapps or something but it's been fixed in the newer nikgapps builds. For the most part this version of lineage has been almost as stable as stock, just occasionally have the camera crash on me.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Yea, this rom is amazing, only thing that bothers me is that gps issue and occasional camera crashes
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] jaggyjagz:
Hey guys. I have been using the LG v20 roms for years, veteran developer here - awesome work!

I am trying to restore a TWRP backup of this rom from exactly one year ago. That backup was tuned with Google Play Store and the downloads from exactly one year ago. When I start my phone, it starts to spend energy for updates - but I am simply unable to download any new apps on Google Play (only update existing ones in the restore twrp file).

The problem I get is "Can't download app", (x app) can't be downloaded. Try again, and if the problem continues, get help troubleshooting (Error Code:403). I've tried wiping cache and data from the Google Play Store, didn't do anything. Any other options available or is there a latest Google Play Store package I can download from somewhere?

Thanks in advance!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] TripOG:
This rom isn't a year old, did you mean to download 17.1?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] e-thug:
This actually does not work. I'm now stuck with Lineage Recovery. The usual methods for flashing TWRP are no longer working. There was no option to install Lineage Recovery when I originally flashed this ROM with TWRP. Even in fastboot mode it will not push TWRP like it used to. LG UP will not recognize the phone any longer while in Fastboot, only while the ROM is running. I'm basically permabricked here. I can make calls and use apps, that's about it.

I appreciate all of the help. That being said, it should have been mentioned in the OP that if you're coming from another ROM and you don't incrementally flash older versions, your phone will be rendered useless (except for Internet and phone calls). This all started with Magisk bricking my ROM with their latest update. I figured I'd give Lineage a try since I was starting over. Followed the install instructions to the T, now I'm here with nothing at all.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Did you try going into download mode and seeing if lg up will recognize the phone then?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] e-thug:
It tells me there is no handset connected as soon as I enter fastboot. With the ROM running it recognizes the phone

Meanwhile, from the command prompt, fastboot recovery flash uploads TWRP, I see it taking on the phone, but it just reboots into system in spite of my command to reboot into recovery after flashing.

Even DirtySanta isn't working.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Try goin into download mode, i bricked my phone the same way a while ago, it wouldn't boot into anything but it was recognized when i went into download mode. then i flashed the 13a kdz and was on my way
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] e-thug:
I get the dreaded unknown model error.

I must have used 10 different variants of LGUP at this point, including LGFlashTool. Getting nowhere. I'd be happy just to use this ROM with the features working. Unfortunately I can't even use messaging. Flashing this ROM according to the OP's directions have reduced this phone to paperweight status.

I challenge anyone using this ROM to try and get your phone back to pre-Lineage status. If you do, I'd sure like to know what you all did to get it that way!

I do appreciate your help, xxseva44. I've never been relegated to permabrick status before.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Wait are your running lg up with uppercut or just using lg up by it's self
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Merazomo:
The reason for me having issues rooting my phone (H910) about a month ago, wasn't so much of a phone issue; it was a computer issue. I upgraded my Windows 10 PC, and the adb drivers wouldn't completely recognize my H910 when it was on fastboot mode after the upgrade (most likely I'm missing drivers on my PC too). I have to manually install the google usb_driver from the "device manager" window on my PC everytime I want my H910 to be recognized when on fastboot mode; the phone is recognized by my computer just fine otherwise.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] e-thug:
That's what I was missing, thank you for that.

I guess before I try this again, going from 12A, are there any particular releases I need to flash before trying this again? Any build of Lineage 15.1, etc will do? Also, is WiFi calling working on Verizon?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] e-thug:
Same. Last time I did this was with a whole different machine. Bought a new laptop last year and didn't migrate my tried and tested working setup.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Any version of lineage 15.1, 16, 17.1 will work, you can flash them one after another in twrp, thats what i usually do instead of booting into each rom. And no, wifi calling isn't working
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] e-thug:
I can't get past the Verizon logo. Think this phone is permabricked from installing Lineage. There is no going back. In spite of a successful firmware flash, it won't completely remove this OS. I can't enter fastboot. I've flashed 12A and 13A and still nothing. Cannot boot into fastboot any longer.

EDIT: LGUP Dual Mode got my phone back. I set Dev Mode and was able to use the refurbish option. If this helps anyone in the future, that's the version you need to look for.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] e-thug:
OK, I'm posting this for all of you who may either install Lineage without doing all the incremental updates (as per directions in the OP), as well as for those of you who may want to opt out of a working Lineage ROM in the future. I'm doing this because I just went through 3 days of Hell just trying to get back to where I was before coming over to Lineage:

If things don't go your way after installation, or if you just want to try a different ROM (or if you just want to rid yourself of Lineage Recovery), do the following:

1) Get the 13A kdz from lg-firmwares.com for your device

2) Get LGUP_DualMode and run SetDev.bat before running LGUPD.exe. This will allow you to reflash your stock kdz in REFURBISH mode, which is the only method that will get you back to stock. From Download Mode on your V20, flash the 13A kdz with REFURBISH checked.

3) You're still not out of the woods yet because although you are back to the stock ROM, you still cannot flash the boot partition without using the RAW command. Use the DirtySanta exploit as directed UNTIL YOU COMPLETE STEP 2.

4) EDIT the file called step3.bat. THIS IS CRITICAL or you will be back at reflashing the stock kdz and doing this over. Where you see the 4 lines that say:

fastboot flash boot boot1.img

Change this to add the RAW parameter (all 4 times):

fastboot flash:raw boot boot1.img

If you fail to do this step, you will get the error: Couldn't parse partition size '0x'

5) Run Step3.bat. Once completed, your device will reboot. Reboot to recovery and you should have TWRP. If you have a VS995 (Verizon model) you will probably be stuck at the boot screen indefinitely. Pull your battery and boot into recovery.

6) You will have to mount System and go to the Repair File System option (this may only affect VS995 users but YMMV). Change to ext2, then change back to ext4. For good measure, I also upgraded to the latest TWRP as well.

7) At the Install option, you should see that 0MB error disappear for your Internal Storage and it should now reflect your actual hard drive space.

8) Flash the ROM of your choice. If you're using Lineage 18.1, be sure to start with 15.1 and increment installations as per xxseva44's direction until you get to 18.x.

I've been having terrible cell reception since I installed this os

I've done the incremental install as suggested by @xxseva44 still the same, any help will be much appreciated
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
I'm having the same issue with both the call reception and gps, i haven't been able to fix it. In anything other than 18.1 my reception and gps work like a charm, but in 18.1 they both have issues Actually, what variant do you use?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hellrose1228:
Same here on a VS995. Notification says "SD card is damaged, tap to fix". I tried using the " tap to fix" option and formating it as "portable storage" but upon a successful format, it still brings up a SD card error notification.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
My sd card was detected just fine, I'm also using the vs995, did you guys come from the official builds or unofficial builds because I went from the stock nougat rom to the unofficial Lineageos 15.1 rom to rr7 to unofficial Lineageos 17.1 and finally to unofficial lineageos 18.1
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Mysteriouslog6:
I went from Android 7 stock rom (Needed for fingerprints to work) and then Lineage os 15.1 then 17 and finally 18

Edit:My sdcard works fine

2 day report of using this rom (VS995)

-ui is very smooth, cameras work, the phone seems very responsive and fast, Instagram doesn't lag/slowdown the phone

Also, I recommend that you don't flash gamma as when I did, the phone would run super hot when not doing anything

Weird things/bugs:

Bluetooth turns on and off before actually staying on, fingerprints get wiped after a reboot, ir doesn't work and i keep getting "com.android.phone has stopped"

Ideas for next build:

-add advanced reboot
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] jailedmike:
Not many do. This is actually because the combo of oems not being willing to release "proprietary information" (As if lg audio recording is so much better ?) and agreements with wireless providers. For inside US: OnePlus, Motorola, and Google historically do. I think asus and Razer do as well. I think Zenphone 6 and newer lack cdma, though most cdma it's going to be shuttered soon. Outside US I know l there are more options though. Like poco,Xiaomi,samsung, and sony. At this point in the US refresh cycle I would be shooting for OnePlus 7 pro probably. Based on it being a OnePlus I would assume full lineage volte/vowifi/volte support. Plus it is not much more then 6t and 5g is mostly stupid unless it's going on T-Mobile. Even then it's best for congested situation like apartment complexes where you know you will have to share bandwidth with extra people. Otherwise your paying for a somewhat incomplete 5g offering. It will probably be at least a year until proposed specs on full future 5g offering are out. We know 5g(they might lie and call it 6g for marketing purposes like they did with 5g) will change due to upcoming c band auctions.

I am curious to know - did you flash the thermal fix - which is on the page for Gamma Kernel. Additionally - have you tried upgrading the graphics drivers?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] hankster112:
I just need to be able to find a phone that absolutely supports VoLTE on Lineage. My carrier is dropping support for 3G in January which basically kills my Galaxy S4 (which supports 4G data but not voice, apparently. From what I understand every carrier's ROMs except for T-Mobile have support for VoLTE on it), so I need a replacement for it. Is it absolutely confirmed that Lineage on OnePlus or Motorola works with VoLTE? Are there any threads discussing it?

Fingerprint now works for unlocking the phone, but no apps are able to use fingerprint.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Yea i used the thermal fix, it worked fine on 15.1, 16, rr7, and 17.1 but on 18.1 it causes my phone to get hot. Also no, I haven't tried to update the graphics drivers
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Nwananka:
The new update fixed the fingerprint issue but broke my bluetooth, it doesn't stay on once i leave the bt setting menu. H918

Note: i dirty flashed the update. I will try wiping phone and install again
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] TripOG:
fingerprint survives a reboot, does not work with apps and I am only able to add one fingerprint before enrollment fails on h910 10/28 build

edit: is it just me or did this build break gestures? i can no longer swipe up to open up the app switcher thing, and I cant find the menu option to change to the buttons either.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
I'm having the same issue, tried a reset that didn't do anything. Although i have a logcat
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
My gestures are working fine, so is the menu (vs995). It could be an isue only on the h910
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] TripOG:
hmm, I'm going to try a clean install and see if it works otherwise I'll have to roll back to the first build i guess.

edit: well a clean install brought the three navigation buttons back and fixed the fingerprint enrollment issue but there is now way to reenable gestures now, the menu option seems to be gone. If you search for gestures it shows in the search results but when you tap it, it disappears.

edit: just noticed the square navigation button doesn't do anything either.

I will dm you this is of topic to much
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] TripOG:
yeah, I don't know whats going on. i dirty flashed first and didn't have the option, tried to reboot a few times but nothing changed, same thing with a clean flash and another one and finally, it just appeared and started working after one reboot. even the square button wouldn't work for a while then it just started working and the system navigation menu started showing up again.

I use us996 although on the board it says vs995 and when I tried to unlock the bootloader on LG's site it says vs995

Had to use dirty Santa method.

Was thinking of flashing a stock modem don't know if it'll help, I'll update when it's done.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
It was most likely converted to a us996, i'd probably keep it the way it is since they're basically the same thing. So this issue seems to be present on the vs995, us996 and H990DS
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] justcosmic:
I asked if/why Ihad to install incremental updates rather than clean flashing this ROM (after flashing Stock 7 and then doing Dirty Santa): Aleastro the dev of this ROM replied that I didn't have to; I could just (clean) flash the ROM directly. If you can explain some reason to the contrary I would be interested to know.

Curent issues I'm experiencing Current Jan 4 2021 installed):

Windows not seeing the phone/storage over USB sometimes when I have my 128gb card in the phone (which the phone sees no problem); works fine over WiFi with MyponeExplorer. Sometimes it sees it sometimes not.

Waze navigation app just hangs on openning screen. Google Maps seems to be OK though.

Camera Apps all seem to crash quite often on changing cameras etcetera.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ottafish:
Sadly, the time has come. After 6 and a bit years of V20 togetherness, and ending up at 18.1, I have retired my V20's from daily life. Whist I love the phone and also 18.1, I was running into many small issues, which mounted up I to daily frustrations.

Without doubt, the best and most stable was Los 16.

What I have rediscovered is the amount of extra bloat on oem firmware that I now loath. But I'm willing to accept that for now for stability and "just works"

My gratitude and thanks for all the work the many Devs have put in to keep the V20 alive so long after LG bailed on it.
