Just wanted to share my experience running this ROM as my daily for the past 2 months. Currently running 2020-05-06 build on us996 on verizon. Everything's been working well for the most part, with the following exceptions:

I seem to be having issues _sending_ SMS when on LTE. I am able to recieve SMS without issue on LTE+CDMA/EVDO, but in order to send SMS reliably, I've had to switch to CDMA/EVDO only.

I can corroborate the bluetooth 5.0+ issue some of the other users have reported. Sound works perfectly fine on my pair of galaxy buds when playing music or watching youtube, but I am unable to use them for calls. However, I am able to use my car bluetooth to make/receive calls, as it is (presumably) using an earlier version of bluetooth. Also, android auto works fine on these newer builds for me :D

One last "bonus" issue/oddity I've experienced is that when pressing the power button, it would try to launch the camera. In order to get around this, I just disabled the "launch camera when double tapping the power button" feature in system settings.

For me, these are just minor inconveniences - I'm looking into using Tasker to automate switching between LTE/CDMA as a workaround for the SMS thing, and I've just been using a wired headphone/mic when I need to make "hands free" calls. These issues aside, this ROM has been rock solid for me. If its possible to fix any of these issues, that's just icing on the cake as far as I'm concerned. Thanks for all of the time and effort you've put into this x86cpu! I cannot overstate my appreciation for having access to new android builds on this device!

Need help

I have a US Cellular V20 us996 on stock Oreo. Here is the process I followed:

1. Unlocked bootloader

2. Used LGUP to flash back to Nougat.

3. Flashed TWRP.

4. Wiped all but SD and formatted (maybe shouldn't have done that but I thought I might need to remove encryption).

5. Flashed LOS 15.1 and wiped dalvik.

6. Flashed LOS 16 and wiped dalvik.

7. Flashed LOS 17.1 and wiped dalvik.

8. Flashed magisk.

9. Flashed open gapps.

10. Rebooted.

It boots, shows the los logo for a few minutes and then boots into TWRP and then i reboot and it does the same over again. I've tried pulling the battery before booting and same thing.

I'm now back to Nougat and ready to start again. But I need to know what to do differently. Can anyone help me?

Edit - I've tried doing each update 1 at a time. I can get los 15.1 to boot. But I can't get los 16 or 17.1 to boot. As soon as I flash either one it gets the loading animation for a while then boots into TWRP.

I'm not sure what else to try at this point.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vortell:
Many try dirty Santa version of us996 as that's what happens if you don't on my us996 bpt or on my us996 cross flashed h915. You could try gamma kernel too.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] bgottschalk:
I tried the DS versions with the same result (other than static while booting). Gamma kernel didn't fix it either.

Basically I can get 15.1 to boot but not 16 or 17.1. Not sure why.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vortell:
Start from behind again then. Sometimes there are firmware particularities in lg phones. Method you use to dirty Santa it seems to affect it. You could first try to start over with alpha omega nougat base rom. It replaces most the firmware. Still at times it seems there only way to fix oddity issues on lg is to use lg up to flash firmware. I would suggest using unlocked us996 as a base. Twrp can flash it too but it's way harder. Search a couple of threads you will see what I'm saying works sometimes, especiallywhen nothing else seems to. I not sure if it's not stack or what. You can try that first by flashing just the modem partition in lg up.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] bgottschalk:
Thanks - I've been using LG UP to go back to stock Nougat before each attempt. I've been using the us996 UCL version since that's what the sticker on the back says and I did get it from US Cellular.

BTW - I didn't unlock with DS. I just used the LG website.

Are you saying to flash the stock Nougat with LG UP and then flash AO Nougat and then 15.1, 16 and 17.1? Or are you saying to use LG UP to flash AO Nougat - can I even do that? Should I use unlocked or universal since my phone is a UCL?

Just crazy how 16 and 17.1 get the bouncing dot when booting to system but then after a few minutes stop and boot to recovery like it got some error that I can't see.

Sorry for all the questions. I've read so many articles and they all say something a little different.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] SammyKitkat792:
Hey [MENTION=2881807]x86cpu[/MENTION] ,I really want to know which is more stable and smooth for h918, the official los 17.1 builds or the unofficial builds provided by you? Thanks in advance, waiting for reply!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] bgottschalk:
One interesting thing in all my attempts to get los 17.1 to boot.

I see the bouncing dot for a few minutes then the screen goes black and it reboots to twrp.

Now the interesting part is at that point the system is always unmounted. I can mount it and reboot and the same thing happens. Not sure if that means anything.

If nothing else is there a way to log the boot so I can see what the messages are when it reboots?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
Hard to catch.. But plug in usb when you have 15.1. get an adb root shell. Accept your computer fingerprint too. Then upgrade to 16.0... during the boot see post 3 to catch a logcat and dmesg. Keep that running.. Then you can retrieve it from TWRP.

Once large difference though from 15.1 vs. 16.0/17.1 is that ALL apps in /system must declare their permissions correctly. Meaning.. Do not place something in there or you could boot back to TWRP. I've also seen bad opengapps cause the same thing too.

Unlocking us996 UCL from LG website is much better than the dirty Santa method. Dirty Santa should only touch the aboot and not any firmware area.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] bgottschalk:
Thanks! I'll give the logging a shot.

As far as system apps I'm not adding any that I know of. I've tried it with no gapps and no magisk - only 17.1. Is it possible twrp could be the issue? I believe it said something about installing itself as a system app.

BTW- I did use the lg website to unlock. I didn't use dirty santa.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
If you get prompted to install TWRP, do not do it. Read carefully.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] bgottschalk:
Prompted when rebooting from twrp? Or do you mean from inside lineage. I didn't install it from the notifaction shade prompt in 15.1. But when rebooting from twrp it said something about installing it so it would stay after flashing and I did allow that.

---------- Post added at 02:31 AM ---------- Previous post was at 02:05 AM ----------

Wow. I am an idiot. I completely misunderstood what that prompt was saying. Or, as you say, didn't read it carefully.

It's all sorted now. Thank you so much for the help and all your hard work!

I have a H990N . I flashed the to-x86cpu.zip file and then the latest build of your lineage OS using latest TWRP but when I boot fingerprint is not working. Is there any solution to this? I am new to this phone phone, so I am unaware of the problems going on. I hhave read the thread and read about gamma kermel. Is that something that can fix fingerprint? What are pros and cons of gamma kernel? Your help will ne highly appreciated.

CAn you please mentione the step by step procedure?

I have tried almost all aosp roms and in all of them during startup it asks for finger orint setup. When I touch the finger print nothing happens. it workd fine in stock rom.

I have tried the following method and failed

flash stock nougat

wipr cache and delvik cache

rebot to recovery & flash to x86Cpu.zp

rebot to recovery & flash lineage os 15.1

After I boot into lineage os 15.1 through this method fingerprint option is completely missing with no option for it in the settings.

Please help!!!!!!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vortell:
What stock rom? How are you getting to stock? Did you test finger print on stock? Fingerprint is based on bootstack in modem partition. There is guide in guide section from i95swervin the same guy who made alpha omega to downgrade just the modem partion. Fyi

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
hey guys, it's been a while. Hope all is okay with the V20 crew. I've been on v30 for a year. nice phone. Still have my v20 for a wifi phone. It's doing a lot of things you wouldn't believe. It's live streaming Facebook groups with a 10800 Mah battery because I had to switch my business to a virtual business and the v20 running off wifi is amazing. It was sprint but I'm no longer on Sprint. I'm on t-mobile now. But the v20 with the removable battery is what I need for business. I'm scared if it dies on me I'm going to have to change how I'm doing my virtual classes. So I am thinking about buying another v20 as backup. I don't care which variant. I just want to root it and run a rom on it. Is there any variant (I know Sprint is done because can't roll back) that can still be rooted with dirty santa? Anyone?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Vortell:
Not TMobile and not sprint. I think all others. Ones i know for sure from us are: us996 all variants ( Usc[us cellular], bpt[bright point],usa[is unlocked] vs996(not sure of battery letters for Verizon), h910(att). The rest i know work but I don't know carriers for: Canadian h915 the same thing as h910,south Korean f800, h990/h990ds. TMobile has very complicated root available but it's way more likely to brick it. As for sprint i know there was a method they were testing for a bit but never kept up to know if it worked. I think it used su98... Some common exploit that they used for other phones too. Maybe even another lg phone. V30/g6? Something like that so if they didn't you could maybe figure out how they got it to work on other phones.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Lillievela:
So ive been thinking about switching to lineageOS for the pie or 10 update. Has SMS been fully fixed on vs995? or does it still require a workaround? Also just to be clear if i do it i need to flash the tox96cpu, then the roms and wipe dalvik cache, storage and data each time? Ive looked at this over whenever i try to flash but i keep forgetting the specifics and where they are
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
Is low mic a know issue on all LOS roms? This would be for example when using a social media app like facebook to stream live. I listened to what I sound like and it is much lower than stock. Is there a fix or that's the way it is?

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
It works fine. I tested it myself - decrypting in recovery is your own doing, and I see no reason to support that, or use it.

It's the only recovery we support for OTA updates, due to having to change our bootloader_message offtset mid-cycle.

Sorry, but that's wrong. Use Lineage Recovery, or, if you must use TWRP, use 3.4.0-1.

You're wrong my h910 doesn't have it and it only displays 4G when making phone calls. Lineage labels AT&T's 3G service/signal as 4G which can be misleading. Your device may be okay but all V20's aren't yet. Furthermore that app tells me the voice connection is UMTS.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] G U C C I:

TWRP Decrypt

Anybody found out, why TWRP doesnt decrypt with LOS 17.1 anymore while it worked with LOS 16?

Its the only reason now, keeping me on LOS 16. The rest seems quite stable now. But not beeing able to decrypt data in recovery is quite a boomer. On my LOS17.1 testphone i cant reflash magisk automaticly on LOS update, because data isnt mounted. And a backup ofcourse is also impossible. Dont know about other sideeffects.

Guess Lineage Recovery wont help either?

I am curious why you are not using the official 17.1 US996 build? It's also working on DS devices (tested myself). You'll get some noise during booting, but that's about it. Turn off screen and turn it back on and it's working. You usually don't boot your device every day, so that should not be an issue.

I am asking because I had many other issues with official 17.1 on my US996-DS (such as freezes on lockscreen, BT calling not working, Wifi crashes), but I think none of them are related to Dirty Santa. How is this unofficial ROM different from the official one? Does it have working BT 4.0 calling?

I have had random issues with not using debug kernel in ds unlocked/cross flashed us996s. Mainly kernel crashes. Last time I just pulled h910 kernel flashed it that solved the issue. Kernel's can do firmware checks though so that's why I asked if I could do it. The otherwise I don't like the static screen. It has scared me into thinking I broke my digitizer before.

Kernel Crash and SD Maid / Databases cleaner

I wonder if you cleaned Databases with e.g. SD Maid Pro as even in default settings it seems to "clean" too many paths (it was over 240 within an earlier build of LOS unofficial). I guess this brought my phone to some strange kernel crash. Tried this several times and if kernel does not crash at least system becomes much slower. So I have flashed my backups and everything works fine again.

If you found another reason pls post.

Hi I am sorry to dredge this old topic up again but am hoping someobdy might have a brief version of steps guide to get our H918's back from LineageOS 17.1 to stock nougat, so I could re-root etc.

I do have TWRP v3.5.0 - 9 on the phones currently on recovery and laf.

Not been able to find much

I figured it would take using LGUP to flash stock 10P, so I ran the laf-recovery.zip from TWRP which did give me download mode back but now LGUP can't recognize the device even with using Uppercut to launch LGUP from, so I'm sort of stuck.

Would go to LOS 18.1 but the motivator for all this of course is the VoLTE cutoff coming from T-Mobile. Looking to buy some time going back to a stock rooted ROM setup til we can find newer phones we like.
