i just installed the Lineage17.1 so far seems stable from the most latest nightly,

has the dac issue been fixed? i ask because when use a dac status app i get dac to engage via speaker but when i use my headphones the status shows disengaged.

and are there any fix files or kernels that can be use with lineage 17.1 that i should look into?

Has anyone here recently tried installing updated OpenGL\Vulkan drivers for their V20 with these more recent Lineage 17.1 versions?

I was going to try it on mine with the SD820--821 V4.2 Magisk module but I'm a bit hesitant about trying the Canary build of Magisk since it will probably render my ES File Explorer useless as a root explorer since newer versions of Magisk are taking it upon itself to block certain apps from elevating to root level.
[LG V20 Guides, News, & Discussion] Rom1995:
Solid explorer is a good option as an alternative if you decided to try updating magisk to canary. Upgrading the graphics driver does improve some games compared to stock but make sure to flash the pie camera driver after updating.
[LG V20 Guides, News, & Discussion] partyman66:
I have Solid Explorer and X-Plore both installed as backups just in case. Where is the Pie Camera driver that you speak of? Don't think I saw that mentioned anywhere yet in my reading.

Help :

i flashed Gamma kernel v20 for Ir blaster but it worked not well.

ir blaster send signals twice at moment.
[LG V20 Guides, News, & Discussion] xxseva44:
What app are you using cuz i didn't have this issue on my v20
[LG V20 Guides, News, & Discussion] partyman66:
I was wondering the same thing. IR Blaster seems to work just fine on my V20 with all versions of Gamma Kernel that I've tried. How are you determining that the IR Signals are being repeated? Are you changing channels, or volume and it's going up by 2 instead of one per each button press? If so, i'd say it's most likely your remote control app rather than the kernel.

Well I got my H990N running with Lineage, just started over with a clean install and it finally seems to be working. Had to do some redo overs, but there we go again :)

I used the H990 Global which as far as I know is the DS version, which has dual sim as well like the H990N.
[LG V20 Guides, News, & Discussion] Jesus is God Almighty:
That was utter disappointing... The sound from the Jack Phone was utter terrible to say the least... Total turn off!

[LG V20 Guides, News, & Discussion] zeroderp:
i just replicated your connection challenge.

i have a desktop i did some deleting of network interface that used USB recognition

edit: to be clear it was the phone that was not giving the option I.E. the usb option was greyed out in network controls, and also did not show on the drag down notifications at all, yet still being selected in the dev opts

that made it so my phone was not recognized by the PC when usb connected (for tethering )

i did my repairs of the dammages on the computer alone, rebooted & i have ability to connect again

this leeds me to ask, did you or your computer do any software updates behind your back

i find updates are almost always bad. i am very very very very very choosiey picky and selective in what updates i run. this is how i avoid most problems other people have. time proven theory. it works.

I'm considering moving to the official build from the unofficial one, but I have some concerns. When I first tried flashing a custom ROM, the official LOS 17.1, (on an F800L unlocked via the Dirty Santa method, now in US996 packaging), I wouldn't be able to boot into the OS, the flash would go smoothly, then when I rebooted, the pulsating Lineage logo could be seen through the static screen, but it shut down after some time and rebooted me to TWRP. That happened over and over again, from what I remember I tried it ~3 times, even if I shut off the device and then turn it on, it would just boot me into TWRP. Does anyone know why this was happening and how it could be possibly fixed? When I tried flashing the x86 LOS 17.1, everything worked well. Are there any major differences between the official and unofficial builds, especially from a security standpoint, and maybe battery optimization?

Thanks for the suggestions, I din't really find out what ARB I have, but atleast I now know what ARB even is. I tried searching for "ARB0" in an Hex editor in the default .kdz file I flashed as seen here, but I couldn't find anything. I also tried booting into fastboot mode and looking through there, but couldn't figure out how to identify the ARB state, as well as calling some phone numbers that should output ARB info and various commands that are supposed to do the same thing, but all to no avail. I'll try to flash the newest version of LOS posted above and report back.

Has anyone found a solution to modem kernel panic/crash? I find it happens in low reception areas. H990DS btw.
[LG V20 Guides, News, & Discussion] Ice Fire:
Hi

I would like to ask if there can be something done about the low microphone sensitivity.

I have both an US996 and an H990DS and on both devices the microphone reception is abysmal.

I appreciate that noise cancelling is kind of working (at least the second microphone gets recognized) but not behing able to properly record WhatsApp messages which is what i do with my phone a lot is a real problem for me.

On RR 7.0.1 i could at least use an app to increase the sensitivity of the mic but this app has no effect on both of my phones using LOS 17.1.
[LG V20 Guides, News, & Discussion] zeroderp:
first idea for me is the workaround.

i am a hypocrite in as much as i preach privacy, yet i use bluetooth.

with that confession out of the way pleas donot kick my face in for it.

that solution would fix all the problems i can imagine. expensive yes? but a magnificent solution.

i suggest bluetooth made for CDL truckers. they are amazing at filtering out noise and focusing on you.

next idea.

i see a pelefora of mods for the second camera.

is there no way you can get a redundant application of approach for the mic instead?

third idea

there are many apps you can boost and tweak speaker and microphone volume with.

i ask you to think of MP3 format.

removing all of the sound frequencies not used by the human ear is what makes those sound files SOOOOO much smaller.

if you get a active equalizer you can tune out an INCREDABLE amount of noise, focus on your prefered sound, and boost it's volume significantly

you might have spent some time playing with the app "audacity" ???

i see no app on the market as amazing for teaching this concept. and it is free.

I LIKE FREE.
[LG V20 Guides, News, & Discussion] wayase8080:
I have no experience with 990DS, but on my F800L flashing Gamma kernel and the stock modem.img worked.
[LG V20 Guides, News, & Discussion] Ice Fire:
First of all. Thank you for that quick reply.

Also dont worry about being the hypocrite here as i am gulty of the same "crime". I use microg on all of my android devices only whatsapp as it has become essential for daily life has remaind since WhatsApp Plus is no more (i hope i can talk about that app here).

As mentioned i tried the only app that truly changes the microphone sensitivity permenatly which is the root volume mixer (a app you would need to pay for so i hope that i am allowed to mention this one too)

This app changes the setting in the mixer path file. This has been the only app i have found this far that enables me to change the microphone sensitity. I would even give up the functionality of the second mic if i could get a more responsive main mic in return.

A different solution from the top of my head would be a mic plug that is pluged directly into the 3.5mm socket and gets defaulted to by an accompanying app as soon as free speak is activated but a product idea wont help me in the short run. (Even though such a mini mic is no complicated idea to think up so maybe i could get one from china then i only have to make it work with automate)

A bluetooth device would get in my way as i would now have to carry two devices with me at all the time.

Just to mention it here i use the Open Camera which supports all three Cameras.

And as freespeak and WhatsApp are my main issues with the microphone i dont think an overlay or an alternate method of recording is going to cut it because i need the recording from within whats app itself. Record via an extern app and importing it could work but would be tedius and this does not solve my freespeak problem ( frogot to add it in the first post)
[LG V20 Guides, News, & Discussion] Ice Fire:
And while we are at it (I put this one in an different post to distinguish it).

As my request is probably very hard to realize and because not everybody would have a need for such an function, i do not even hope that this will be implemented.

If one does use this rom in landscape mode on ventures to youtube, one will quickly notice that the notch cuts into the display area of the video. If we no go into the Developer setting and use the simulate display cutout option to simulate the absence of a cut out or in other words turn the cutout of the video gets displayed properly in landscape mode. But now when we change into portrait mode we have a non functioning cutout with the status bar intruding onto the normaly vacant home screen and beyond that the status bar is huge.

If it where possible to turn the cutout off as soon as the landscape mode is detected and back again if not, i would not have a problem but it takes a lot of time for the system ui to adjust to the changed settings and it is not nessesary to do so in every app.

A different and probably the most feasable sollution would be a quick tile connected to the simulate display cutout setting which, upon behing pressed changes the state of the cutout setting. I tried many methodes of achieving this myself but i ran into the problem that i could never detect the actual name of the function in order to create a custom setting in an automation app or whatever else i have tried over the time. So now that i have done everthing i could, i would like to ask here if anybody has any information about if i should hold my breath any long for this option.

[LG V20 Guides, News, & Discussion] Anon_404:
Hey, how do you guys root the V20 after installing Lineage? I have the h918 fully flashed and backed up, but idk the best way to go about root...

On the official Lineage site, they have SuperSU for download, in the extras section, but it's named "addonsu-16.0-arm64-signed.zip", and version date is 2019-07-09. That suggests it might be incompatible with Lineage 17.1 . Also, I recently heard SuperSU is closed-sourced and was sold to some company not long ago. I never imagined.

On the other hand I see Magisk becoming prominent, but it gives me some worries. First it's labelled as "systemless root" that hides the fact that the phone is rooted in some weird way. I don't need any of those shenanigans, I'm fully degoogled. Second, it seams you install it by patching boot partition? Sounds like a bad idea...

Third, recent new version (v 22.0) seams to have been a big change. I was reading the updated official install guide and idk if "Custom Recovery" method will do same as patching boot or not. See here: https://github.com/topjohnwu/Magisk/releases/tag/v22.0

Can anyone shine any light? Even if just telling me how you rooted the V20 in your case.

[LG V20 Guides, News, & Discussion] zeroderp:
i also have a few h918s'

all i ever use is magesk

currently using the 22.0 that you have to rename. and it is epic. best dev trick i seen in a while.

one download, you can put the same on copy paste into your APK folder, your zip rom tool folder, and if you have one delete tools folder. just rename it .zip or .apk as to the job it is intended to do

i do not have that one in particular because my twrp is the only delete tool i ever use

when your in twrp install the magesk 22 zip AFTER the rom install, when your in the rom as a end user then install the same file now name altered to end in .apk

done. you should have root.

from there the tricky part is getting a root tool worth having.

some devs are restricting root tools so you as end user do not have the control over the rom you need. like giving apps unlimited GPS tracking and there is nothing you can do to stop it.

seriously NOT cool. but trust me. with the right app you can murder such stupidity. you just have to find wich one you need.

[LG V20 Guides, News, & Discussion] itt533:
AFAIK it is due to lack of technical documentation from manufacturers that no properly working open source driver of the audio sound card that the audio capturing ability of the v20 with LOS is not good at all. Not forgetting this device has 3 mics.

As for the landscape mode i confirm the problem. For me it's a bug, the whole screen width is set to be equal to the width as given by the manufacturer + the "height" of the second screen (actually the width since i'm talking of landscape mode). Therefore, in landscape mode a part of the image is missing.

The sound problem is even worst with RR 7.0.1 there only one mic gets detected (or only both of the bottom mics which is worst in the configuration RR uses them).

i used the last non official release of RR for long time. It was recording in stereo with the bottom mic and one of the two at the top of the phone. The sensitivity was a little bit better by raising the gain to 400%, which is the max., in the FOSS "stereo recorder" app available on f-droid.org.

I believe the last Gamma thread was on LOS 16.1, but around the last pages of that thread there is a long discussion about later LOS and its compatibility, and there are countless posts recommending gamma kernel alongside LOS 17.1 in many other threads.

>Also is it really fully open source?

Second screen works, I haven't tried the IR blaster myself, because I can't find an open source app for utilizing it, but yes, it is supposed to work.

I went through a lot of hassle rooting my h990ds and finally succeded using this Instruction (according to the instruction I'm coming from StockROM with twrp-3.0.2-1-h990.img and SuperSU installed right now).

Maybe a stupid question...

Will my phone still be rootet after performing the recommended factory reset within TWRP?

I dont want to lose my root because of this.

In the install instructions for LineageOS its written:

"Installing LineageOS from recovery:​

3. Now tap Factory Reset, then Format data / factory reset and continue with the formatting process..."

Another question:

Is it still ok to stick to TWRP instead of LineageOS recovery while installing the newest version of LineageOS (coming from stock)? Or will this lead to any problems?

I've never used the new LineageOS Recovery on any of my other LineageOS devices untill now.
