Has anyone succeded in flashing this rom on a F800 variant?

I'm currently using WETA (stock android 7 based, vs995 version).

I tried following the procedure mentioned in the first pages (to-x86cpu.zip-> 17.1unofficial -> 17.1 official)

The to-x86cpu gave as error "packages.xml missing"

I modified the unofficial 17.1 updater script to avoid the version control. Flashed and the result Is kernel panic (green screen).

Can anyone help me? Thanks

[LG V20 Guides, News, & Discussion] Gorilla Daddy:
Video doesn't play in Google Photos or WhatsApp, on lineage h918 releases after 10/29 for me. Anyone know why or have a solution? 10/29 will work fine with any gapps up to 11/19. But any lineage release since 10/29 I can't play the videos.

Thanks.

I cam from unoffical lineageos 16 with my H990DS - everything worked except IR (and i miss the original camera, which is much better than the lineageos one sadly)

Upgraded to official 17.1 yesterday by wiping, flashing, flash gapps nano, flash Magisk 20.4, and it booted fine.

Sadly i still have the same problems with IR.

Some people said it works fine with the right app.

I Tried "irplus" by "binarymode" this app manages it to send 1 key correctly, after that no further signals can be send correctly. I noticed with a camera that the app still sends followup signals, but their PWM pattern is so slow, that 1-2 seconds are in between them.

I also tried other recommendations here: Mi Remote, Lean Remote, both show the same pattern that irplus shows, but i did not manage the identify my tv here, as i have to reboot after every try (and cant use the model name).

Asking this, is there a guide how to build and flash your own modification of lineageos ?

Edit: found it https://wiki.lineageos.org/devices/h990/build

H918: Is it safe to replace LOS 17.1 with stock firmware?

Hello. I have an LG-H918 onto which I installed LOS 17.1 (20201015 I believe) using this guide. I now have need to return to the stock firmware with which I received the phone, 20H. Is it safe to simply install the KDZ file over LOS 17.1 using LGUP?

Can I even use LGUP now that download mode on my phone has been replaced with TWRP?

Unfortunately Lineage 17.1 is very unstable here - its 'fine' after a fresh boot - but when I am not wrong, the problems start until the battery charges up to 100%.

When I charge it to 100%, my fingerprint-sensor disappears...any ideas whats causing this?

Lineage is up to date and OpenGapps (nano) too.

Many thanks already.

Btw, its dirty-santa rooted and a Vz995. Everything is fine so far except the fingerprint-sensor....just works after a reboot. Magisk was installed and is uninstalled atm through the apps uninstaller. I assume its a problem of OpenGapps, are there any known issues?

Is it possible to uninstall OpenGapps?
[LG V20 Guides, News, & Discussion] jmichael2497:
looks like 2 for ir only works with gamma kernel?

not conclusive.

same experience using that app on h918, so based on other posts, looks like have to use whatever gamma kernel is, instead of the official LOS kernel.

my current older ir blaster capable LOS P phone is acting up more, so i should switch to v20 or something soon, though i'd rather stick to official LOS builds instead of having to add more variables like alternative kernel for basic functions to work (other than magisk for root).

edit: confirming downgrade from LOS kernel 3.18.113 to gamma kernel 3.18.71 fixes ir blaster, able to get more than one button press to function in remote app, but has obvious security implications. must flash this after every os upgrade, along with suggested audio and thermal patch from that page.

(side note, switch to gamma kernel still did not allow FM Radio to function)

After running the updater for Lineage, do I need to flash the gamma kernel again? While I've lost some bugs, the performance seems a bit off. I am wondering if that is the cause.
[LG V20 Guides, News, & Discussion] itt533:
I'm currently running the nightly 20201122 release. Very surprised how well it works compare to what i tried some months ago. I have used for long time the latest RR as at that time (Feb. March 2020?) it was working well enough, but now with LOS i discovered that RR was not optimised at all. Running VLC was leading to high cpu heat and within two to three hours the phone was used to run out of battery, even for only audio. Now with LOS just about 20 to 30% is used for the same time duration of music.

But still there is the audio recording issue being that the sound is very weak and noisy. The DAC is not working (BYPASS). My device is a h990ds.

My H910 flashed this ROM yesterday and everything seems smooth but accepting battery drain out quickly, Now cannot last for half day for a full charge for medium level usage. Before updating from unofficial LOS 17.1 to this official LOS 17.1, the battery can last full day. the battery drained out from 67% to 0% under idle for 5-6 hours.

This really drives me crazy.

Am I the only Vz995-user here having problems with loosing fingerprint-sensor after charging to 100%?

Unbelieveable how many lifetime I've lost on this mobile....

I've now started from scratch. See my earlier posts in the dirtysanta-thread, flashed us996-kdz through LGUP, dirtysanta-unlocked it, then installed Los-x86 15, 16, LOS nightly 17.1.

Without any Gapps (!).

After every flash I checked this damn fingerprint-sensor - nothing. After the whole process and first bootup of LOS 17.1, everything is fine - fingerprint is recognized and working as it should.

Until I charge this mobile - when it reaches 100%, fingerprint crashes. And it looks as if also the QuadDAC-functionality breaks, not sure as I never used or checked it if it works at all.

If it is the bootstack (>dirtysanta-thread) - why does it work fine after the first bootup? If it really is the bootstack, shouldnt it be 'defect' on first startup, too? How can the bootstack cause a crash when I charge the phone to 100%?

However, I want to figure this out more precise! I am so tired of all this trial and error....can someone please tell me exactly how to catch this bug precise exactly?

I'll do a fresh install and want to get a useful log of the crash - but how? What do I have to do, to see what exactly crashes when I charge the Vs995 and produce a useable bugreport for someone?

Beside the log, if its caused by my "Us996-kdz/LOS-Vs995 cross" - why does fingerprint-sensor work on first startup at all?

Strangest point of all is that everything was fine until some weeks ago the way I did it...I did exactly the same and have had a working sensor for weeks. I do not know what went wrong here, I def need to find out more precise details what is causing this...but how?

I want this terrible crashes get fixed for my V20 and a stable mobile/LOS install...who can help me and how can I help to produce a useable log of the crash when I charge it?

[LG V20 Guides, News, & Discussion] Ms0206:
Doing further tests: after the fingerprint sensor broke/was gone, I was not able to let it reappear - I did a factory reset, from OS, from Twrp, no success. I wiped Dalvik an cache, no success. I did several reboots, no success.

I started into Twrp again, wiped system, data and internal storage + dalvik, reflashed LOS x86 15,16 and Los17, no success - still no fp-sensor anymore.

I did it again - went into Twrp, wiped everything (System, data, internal and dalvik), reinstalled x86 15,16 and Los 17 - have not wiped Dalvik after this and instead of rebooting, Ive shutted mobile down and pulled the battery out.

After a reboot I am now sitting infront of 17.1 and it asks me to set fingetprint for display?!.

So I am wondering what made it reappear - that I've pulled the battery out or the miss of wiping Dalvik after installing LOS x86 15,16 and current 17.1 ....

However, it is working now until I charge it to 100% and I know how to reproduce everything.

Whats next? Neet a good dev now, telling me how to create a useful log when I charge it to wipe out the problems. Need to figure out max details now to solve the crashing things in the background when I charge to 100%.

I want this instability ironed out for everyone and all time, it sucks completely. So - how? Every help appreciated!
[LG V20 Guides, News, & Discussion] Ms0206:
Update: a reboot was fine and without any problems. Charged to 98% and started system trace in dev-options with almost everything marked in hope to see anything when I charge it to 100%...but this time it did not break....mysterious, completely.

I'll watch this and try again tomorrow...it definately crashed many/all times at charging - I dont know why it not crashed this time after I am prepared.

[LG V20 Guides, News, & Discussion] Ms0206:
I am running out of ideas whats going on here - everything was fine tonight. I thought there could only be 2 possibilities:

1. wiping Dalvik makes the system instable somehow

2. or the timespan of my charging was not long enough to make it crash

Today I made several reboots, installed all my apps...everything was fine. Then I thought a dump with LGUP would be a good idea - so I (mistakenly) booted into fastboot mode and then pulled battery out when I recognized its wrong and restarted to download-mode - and made a full dump.

After this I pulled the battery out, rebooted - fingerprint-sensor is missing! Wtf??

Happily I was able to make it reappear - after I wiped Dalvik cache, made it shutdown, pulled the battery out and restarted. But what the hell made fingerprint crash this time?

Later today I start a trace and charge it....

[QUOTE = "Ms0206, post: 84083081, member: 10865713"]

У меня заканчиваются идеи, что здесь происходит - сегодня все было хорошо. Я думал, что может быть только 2 возможности:

1. wiping Dalvik делает систему как-то нестабильной

2. или время моей зарядки было недостаточно продолжительным, чтобы вызвать сбой

Сегодня сделал несколько перезагрузок, установил все свои приложения ... все было нормально. Затем я подумал, что дамп с LGUP будет хорошей идеей, поэтому я (по ошибке) загрузился в режим быстрой загрузки, а затем вытащил батарею, когда я понял, что это неправильно, и перезапустился в режим загрузки - и сделал полный дамп.

Cameraproblems with Lineageoes 17.1.

The defaultcamera is a joke, because you dont't have the wide-angle lens. So, you need another cameraapp. But which? Almost all apps crashes or are very sluggish. The only cameraapp, that works is camera zoom fx, but there, you can't make videos. All gcams are crashing. Why does the default app have no wide angle?? Why can't the stockcam be used? Or another question: Do I need a special kernel, that works with the gcams?
[LG V20 Guides, News, & Discussion] rlvddoes@gmail.com:

No, it doesn't. Do you have camera api 1 or 2?
[LG V20 Guides, News, & Discussion] rlvddoes@gmail.com:
Both work fine, but I use API2.

All 3 camera's can be selected.

Maybe you need to clear the cache (off all camera apps).
[LG V20 Guides, News, & Discussion] martinsche:
Open Camera has the problem with the fokus. When you put infinite and you take a picture of, for example a mountain, the picture is not sharp.
[LG V20 Guides, News, & Discussion] rlvddoes@gmail.com:

But in the meantime my 910 runs very fine and stable on LOS 18, so I can't check it on 17.1 any more.
[LG V20 Guides, News, & Discussion] martinsche:
I tested it. With API 1 it worked passably. With API 2 one crash after the other. Ok, i clean the cahe. Have I to clean the cache every day 20 times??? With the stockvam, all works excellent.
[LG V20 Guides, News, & Discussion] rlvddoes@gmail.com:
No, cache clearing should only be done once, after installing any camera app.

ROM works great but anybody successful with rooting (with Magisk 16) immediately after format and flash of ROM? I keep getting that error 1.

I tried using the Lineage recovery as well as TWRP.

I'm using the latest nightly for H918.

Even restarted all the way from step 1 of this guide and still root fails after flashing Lineage.

EDIT: I used the latest Magisk 21 and it worked!!
[LG V20 Guides, News, & Discussion] jmichael2497:
similar frequent camera crashes with third party messengers or OpenCamera app on LG v20 H918.

i am using on H918 10p to LOS Q updating with every monthly security update (currently 2020-12-17), opengapps nano 2020-09-17, magisk v21 and props config hide to pass play store check, then gamma kernel to mostly fix ir, flashed recommended thermal (still can get pretty hot) and audio (though still terrible pops within last 3 notches of volume on speaker playback).

i've disabled browser, camera, gallery, google, used titanium backup to clear user and system dalvik cache, twrp 3.3.1-1 Phoenix591 2019-10-05 to clear cache, too.

still too frequently get message generally reproducible going from OpenCamera 1.28.3 finished photo or video (when it doesn't go black screen or freeze) to Simple Gallery 6.18.0 and back to OpenCamera will get error "failed to open camera. camera may be in use by another application? id:0".

close and reopen fails to start camera2 api (seen in OpenCamera by missing iso options), will fallback to camera1 api instead, have to close and reopen to get camera2 api again.

this can also happen in other apps, like using various messenger apps to take a pic to send, seems like after failure needs long while to kill and reset camera, will miss any spontaneous moment (or get tired of posing).

other threads suggest it is a driver update needed.
[LG V20 Guides, News, & Discussion] partyman66:
I'm using the nightly ROM from 12-24-2020 on my H910A with TWRP and Magisk 20.4. ROM runs absolutely blazing fast and really smooth. It's literally like a totally different phone than it was on rooted stock-based roms. No crashes at all over the past 3 days of use yet. Battery life is slightly better than on a stock based ROM but my phone is and has always been horrible on battery even at idle in airplane mode(probably bad hardware somewhere internally burning up 2-3% battery per hour doing nothing with screen off on every rom and even just sitting there idle in TWRP).

The main really annoying thing is that I can't get the fingerprint scanner to work. I was on Oreo before this so that's probably why(tried installing ALPHA-OMEGA Nougat rom first then installing LOS 15.1 over that and then 17.1 over that, but still did nothing. I don't think there's any way to downgrade AT&T version of V20 to nougat firmware since they don't publish KDZ files for it (unless someone knows of a way... Please speak up). This really pisses me off because I have to use double-tap to wake and then enter my PIN to unlock the phone every time I want to use it. I don't like using the physical power button to wake because that type of thing eventually wears out your power button when used constantly every day for each and every wakeup.

Other negatives:

-Bluetooth call quality over a headset sounds very tinny, weak and grainy. It's pretty bad and people you are talking to notice it. On a scale of 1-10, the bluetooth call quality is probably a 3.

-Camera app is very simple and has no wide angle support or burst shot.

-No WIFI calling or VOLTE (as we all know)

Unexpected other Positives:

-I've been told by others that my Skype video is much clearer and brighter on this rom than my stock-based AT&T rom.

-It seems that MMS videos I receive from others are less grainy than on stock based AT&T roms.

-Hotspot works really well. Very fast connection for clients.

I also found that TWRP backups of LOS 17.1 don't seem to restore properly to my phone. When I try restoring a backup of LOS 17.1 it just boots into fastboot screen after the restore finishes. I haven't tried using the lineage custom recovery.
[LG V20 Guides, News, & Discussion] partyman66:
Man.... Oh man did I just shoot myself in the foot trying to get this ROM to have a working fingerprint scanner on my H910A. I tried to revert to Nougat so I could do a stock based Nougat --> LOS 15.1 --> LOS 16.O --> LOS 17.1 official progression, but I ended up bricking my phone and having to use LGUP to revert back to the h915CA KDZ, dirty Santa root it and then flash stock Nougat again. Then I couldn't get any LTE service apparently due to modems and I also couldn't get any version of LOS to boot up past the initial Android configuration screen(modem based kernel panic). I also couldn't get any of my TWRP backups to install the system patrition due to some odd TAR error.

Eventually got it all back up and running on my TWRP backup image of fully configured stock based Oreo after staying up all night and halfway through the next day trying hundreds of different things. AT&T sucks with their no-KDZ bull$hit.

So I'm real curious if anyone on an H910A actually has LOS 17.1 installed with working LTE, all sensors and camera and if so what their install procedure was?

H990DS user here.

Amazing ROM, flashed over dirtysanta'ed 10d stock version: tinkered a bit for an hour, so far so good. In fact it's almost perfect to me.

Few notes:

0. No issues with fingerprint scanner.

1. Performance is impossibly better over the stock firmware.

2. We even have a dedicated Quad-DAC tile!

3. Both sim cards work.

4. Because of the new notch, the 16:9 Youtube videos are partially covered by the front camera (not a major downside to me).

5. The only relatively major bug observed is 5 Ghz tethering not working. Once this gets fixed, we'll have a perfect 4G+ wifi access point device (with 5 Ghz and removeable battery).
