you may have run into whatever issue i had that required switching from TWRP to LOS recovery a few months ago due to bootloop.

basically had to flash latest LOS recovery, use that to reflashing LOS plus noticed updated MtG, then had to reinstall several google apps over themselves to fix permissions errors.

i posted in thorough detail about my troubleshooting method and all that fun stuff on reddit, since i use that regularly.

if you haven't noticed by now, everyone will be requiring VoLTE but that and VoWiFi both are industry hot messes for the last decade (this has been causing so many problems for me through supporting my parents in the last couple months).

my recommendation is move your phone number to a voip service, like google voice (for americans), then you can at least avoid some of the hassles, but still may potentially be issues calling 911 as that is not really clear (and likely also broken by ATT whitelist crap).

Is it okay if I ask how you guys are getting along? I see there's always some work done on your Linux 4.4 repositories on Github but since this reply I get the impression that you talk about support for newer Android in this thread pessimistically nonetheless for some reason.

Is it possible to give a rough judgement on the chances of us having Lineage 19 (or preferably above, wouldn't mind seeing Android 12 skipped) by the time Android 11 stops receiving security patches from Google?

I only recently moved to the V20 (might be a bad idea in the long run but even if that's the case I'll at least have experienced the swansong of old-style phones in terms of batteries, etc :D It's been great so far) and just want to have those security updates for more than ca. 1.5 years if possible.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] rftgyhuj8i9o0pq2w3e4:
Also thank you so much for the work on LOS, at least to @npjohnson (idk how much work anyone else put in lol). As things are LOS 18 is serving me well, I don't have any meaningful complaints.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] AShiningRay:
Well this is getting a bit off-topic given what this thread is about, but i think i can answer that briefly.

The short answer for the 4.4 kernel is: So far, it's working reasonably fine. Most things work and in theory we can get Android 12 running on it as of now. However, what doesn't yet work is pretty critical to the phone, namely USB, Audio and Camera (there's probably something else, but i'm not home to look at the local docs right now). Every single one of those is pretty complicated to fix due to the lack of documentation, and none of us being well-versed in low-level stuff like i2c calls and etc. but we're trying to get more help though.

As for the rough judgment... well, the chance is 100% now, the V20 can get Lineage 19-19.1 running on the 4.4 kernel with some work, but those problems above will render it basically unusable for most. The overall negativity surrounding the newer android versions is because we don't even know if we'll be able to get the newer kernel working 100% with the phone since we've been stuck with those three key difficulties for a while, hence we don't think there will be a perfectly functional A12 build for the V20 very soon and are refraining from bringing it up all that much.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] pranciskus2:
For me camera is slow and freezes (usually when quickly zooming) often, didn't pay attention when it was less than 50% or not. Currently using an original battery (about a week old) H990DS

Edit:

Unfortunately, Open Camera just froze me while being at 50% and plugged in. I think it can always freeze for me. But I opened it quickly after restarting my phone. Not sure how would it go under normal conditions.

A bit off-topic again, but oh well...

For those looking for a gamma build to use the IR Blaster: One way of getting it up and running for now is by compiling from source. Last i checked (might be wrong, since i only compiled it one or two times to check the IR output while debugging other kernels), the gamma-oreo-stable branch is the one that has working infrared.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Xanvast:
Hi, I need help to solve an issue with my mobile network not working on this OS. I'm new into all this therefore a bit lost. I have found some others with similar issues and a beginning of an answer but it is still unclear to me what is wrong exactly and what to do to fix it. All the different versions make it confusing.

A little recap of my process so far :

I got my LG V20 H910 ~10 days ago. It was new and running an old android 7 from Dec 2016. So from what I gathered no need to downgrade or change versions.

It took me a week of research and preparation to feel comfortable to execute the steps in this guide

[LS997|VS995|H910|F800L] DirtySanta Bootloader unlock and Root guide

A couple of minor hicups along the way but in the end it worked, the bootloader is unlocked and twrp-3.2.1-2-h910 is installed, I used this build lineage-18.1-20220623-nightly-h910-signed afterwards.

I flashed this version SR5-SuperSU-v2.78-SR5-20161130091551, now for some reason the root checker indicates no root but this is another problem I'm not too concerned about for the moment.

So everything is working fine that I can see except the mobile network data. I can send and receive SMS but not call and get called. I am unable to connect to 2G, 3G and 4G at all. My carrier is SFR (France). The APN is correctly configurated.

From what I have read it could be an issue with the aboot.img that is incompatible with the modem or something.

If the solution is involving rolling back I have never done it, please provide all the steps. The above is all my experience in this domain. Is there another version or another OS that would work with my configuration ? If there is a quick and easy flash fix that would be great. I don't care about the android version I end up with I just want a clean debloated system.

Thanks in advance for your time.

Edit : looks like it was not to do with the OS, I had the same problems with another custom rom. My issue is not solved yet.

Would recompiling gamma be enough? Aren't lyb's modifications necessary for the camera to work?

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Hadi99:
@npjohnson

Thanks for your contribution. The rom feels smooth and as stable as ever.

Noticed a few things though. An oreo base should be recommended if camera performance were to be a priority. Having an oreo base seems to fix the choppiness in video recording. Of course at the expense of fingerprint unlock

I know this is going to be obsolete at the end of the year, due to volte, at least for us on Verizon. But I want to get around to it sooner than that. Is there an up to date rom based on stock that will work, and if so, how can I move over?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Hadi99:
Try reverting to stock (including stock recovery) and performing a factory reset through the SVC hidden menu. Be wary that all your data will be erased.

To revert, use the modded LGUP to partitionDL to a us996 or VS995 nougat kdz. Select all partitions except aboot.

USB-c to charging hub with HDMI will not work right on this rom still. It will charge to 100% working the whole time. Once it hits 100% it stops charging and will not start the charging until hub is unplugged from the phone and reconnected.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
I am really struggling to understand what you're saying here, so you want your phone to charge past 100%?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] askermk2000:
You want the phone not drop in battery after it reaches full? This is from what I recall, normal behavior even on stock.

You might be able to prevent that by using ACC (Advanced Charging Controller) or similar app. You can slow charging down, set a limit etc.

If you don't reach the max voltage (i.e set a lower limit) then perhaps charging can resume again, without unplugging first.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] jailedmike:
No, what's happening is instead of it staying at 100 % well being continuously plugged in the battery will drop until it turns off. This only happens with a charge capable HDMI adapter.

The adapter has been tested to work correct on lg g8 op8t and stock lg v20.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] askermk2000:
That's what I meant with what I said. Staying at 100% and "not dropping in battery after reaching full" is the same thing.

Have you tried my kernel BTW?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] jailedmike:
No the USB pd standard adapter should be able to maintain 100% level well in use

I'm the past yes your thermals used to be better l but not this time.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] askermk2000:
I'm talking about the mk2k-custom kernel, just to be sure. And it wasn't just a loose unrelated question, I was wondering if the type-c hdmi hub behaved the same, and if you didn't test I suggest you do.

If the problem still persist, we can be almost certain the problem is in the ROMs charger/usb configuration.

I have the same issue with lineage-18.1-20220623-nightly-h910-signed. Did you find a solution ?

What could be the cause ? Was it fixed in a subsequent release ?

It appears to me that some necessary services might not be running in the background to be supplying these notifications. I'm not getting notified of Discord/Skype messages nor getting the call if I'm not in the app open in front of me.

Thank you

Edit : Signal works, it stated that it can compensate for the lack of google play services and disable battery optimizations that prevent it from getting messages while inactive. It then created an authorization to always be run in the background. Unfortunately I have not found a way to replicate this for other apps, the options is simply not there. Also removing all battery optimizations did not help.

Edit 2 : any way to get notifications to work without installing anything google ? And without google cloud messaging through microG.

Edit 3 : Skype Lite works and Discord is going into the dumpster.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Xanvast:
I have another issue I need advice on. I am getting kernel crashes and random reboots in a few instances. One of them is calling and being called : 100% of the time. Another is when using Skype Lite and browsing something else : high risk.

I might add that the phone is chewing up the battery faster than stock and getting hot when video chatting.

My whole detailed process until now is detailed on this thread. This is my second installation of LOS 18.1. The difference this time is 4G works and I'm getting kernel crashes. The rest didn't change. I'll sum up real quick.

So what led me to this : I've followed this procedure [ROOT] HOWTO: AT&T H910 up to v20g (FULLY TESTED) by using a H91510e kdz as a base. The issues started at the very end when flashing the h910-10r.rar and then Magisk-v19.0. I would get a secure boot every time even after formatting. After a few times it became a green screen kernel crash and at that point I couldn't get into TWRP anymore.

I ended up restarting from scratch with a H91510e kdz and redoing the rooting. This time I didn't get to TWRP to flash anything I got the green screen crash again it was still there. I managed to boot into recovery by flashing another boot.img and then the h910-10r.rar again without magisk this time. But same result with secure boot even after formatting.

What I didn't know at the time is that the h910-10r.rar provided at the end of the thread (because it is now unavailable in the OP) was missing the mk2000 kernel and therefore I didn't flash it.

So with that endeavor going nowhere I ended up installing lineage-18.1-20220623-nightly-h910-signed.zip instead like the first time and this is where I'm currently at. It works well but the battery is going down faster than normal (maybe 1h40 in autonomy for video chatting, should be over 2h30), it overheats and I'm getting kernel crashes that I'll attach below.

This post is displaying a very similar issue and fixed it by flashing h915freedommobilemodem.img. Is this going to solve it for me too or is there something else I should do ? If I go ahead and flash this modem, how do I go about it ?

Thanks !

Edit : I just noticed my phone won't go into headphones mode for some reason when plugged in and the HIFI Quad DAC is unavailable but that's another problem.

Edit 2 : Well no it didn't help at all. At least it didn't make it worse. I'm still getting the kernel panic crashes. I will try the one from this post now.

Edit 3 : I thought at first that the H910 modem fixed the crashes, it worked no problem for a day but it happened again 4x the next day.

Edit 4 : the H910_v0.7-mk2000.zip kernel for Lineage seems to have solved it for me. Thanks a lot to who made it. I was ready to give up.

Edit 5 : black screen kernel crashes have stopped definitively yes but they are now replaced by blue screen modem crashes and orange screen adsp crashes. I think this is the end of my LOS adventure.

I can confirm LineageOS has been working great on my H990DS and I still get updates, it just needed some special step to unlock the bootloader before flashing. Feels like a brand new phone.
