True Chainz

Ell yeah other Mario! Sorry to dilute thread even further, however I am looking into compiling ROMs from source and may make an attempt soon to make it happen for android 11... I'm a complete newbie to it but I do have YouTube on my side (; Anywhoo, take care 'yalls and God bless! :good::good:

I also began writing init.d scripts to further enhance the wonderful experience Travis provided:) these little tweaks and modifications under the hood are furthering my exp. I have a pretty good understanding of the components of the os; esgetit

Thank you Travis for this wonderful Rom, coming from a Google Nexus phone, i did not expect the same class of community support with this device, but you have done an excellent job with it, battery last nearly like the oem Rom, android feels fast after several months with a lot of installed apps, (have to froze a few i did not use to often, remember our phone is a simple snapdragon 400 series), no problems with cellular network, bluetooth, and wifi, only gripe is (and asking anyone if you have this, and how to solve) with headphones, i feel volume to loud, if i decrese volume even at minimum there is no difference in calls and ringer or notifications sounds, when listening music its normal as any other phone (no glitch), i am happy with this phone thanks to you, using magisk and xposed as always, do you know any way i can try to solve this?

Thank you.

Backup first then tinker with the mixer volume xml files, in /vendor you'll have audio_policy_volumes.xml and default_volume_tables.xml. You can edit the volume curves and (i haven't tried this yet) maybe add an extra line to the parameter set in question so as to create a more subtle volume increase/decrease and make the oft annoying experience of having almost no loudness to sudden loudness more tolerable.

In these files, you can increase the max and min volume curves. The step index points go from 0 to 100, with the volume attenuation curve points going from -9000(min vol) to 0(max vol). So at 0 you'll want to set a low attenuation, probably not -9000 as that is completely silent. Likewise at point 100 you may not find the loudest attenuation of 0 desirable. It may be that for the headset or speaker, at index 100, a level of say -1500 might be enough. The points in between would form the overall curve, so at index 80 you might want -2800, index 30 -5000, index 10 -6800.

You'll find the values in nested sets each controlling a device audio channel and output.

Camera stopped working

Hello, I do not know if someone else fails this but I got into the camera application that it brings by default and it tells me camera stopped working, to someone else that this happens?
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] cvmg333:
Hi, no problems here with camera, but i use open camera the most, more adjustments than lineage camera.
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] RebelLion_:
Try dirty flashing lineage and using open camera as suggested. It should be the default for custom ROMs really as it seems to be the most universally compatible camera app

Hi i just installed this rom its great i read through all the posts to see if anyone else is having issues passing safety net with magisk ive tried everything and cant get it to pass had it pass basic once but not cts do i need an older version of magisk i dont know much tia for any help
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] jasonmerc:
Is this ROM still being maintained? My buddy is gonna give me his old T-Mobile K20 Plus relatively soon, so I'll soon be flashing this since it's the newest ROM for this phone that's out there. If it hasn't been updated in a while, if you all want I'll download the sources linked in the OP and do another build just to bump up the security patch version at least
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] Psymatics:
I think his current plan is to drop an LineageOS 17 ROM based off off the Stylo 3 (??) once/if they get it working, but I think that project stalled out at some point. I have a K20+ that I use for stuff (though the SIM tray is broken somehow, so an update would at least be appreciated by me!
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] jasonmerc:
@Travisholt92 just wanted to pop in and ask real quick. In your Github repo sources for LG-SD4xx, there's multiple Oreo trees for the LG devices. I see some that are called "lineage-15.1", one called "8.1-n-cam", another called "8.1-ph2n"... and so on

What I wanted to ask you was, which trees do you recommend using to compile for this phone? For stability, ideally. I don't mean to steal your thunder, I just wanted to recompile again to at least bump the security patch version of this ROM here.
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] mario0318:
Oh man. I would absolutely encourage you to build and pick up where @Travisholt92 left off. If Im not mistaken he has since moved on from the K20+
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] jasonmerc:
Been a while since I made that request. Once I get my piece of junk laptop up and running I'll see what I can do as far as building for this too if you want me to. Only issue is, if you read my previous post, I don't know what trees to use. So the ROM I build might break things for you guys if you update to it.
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] mario0318:
That's a risk I'm willing to take. The K20+ was my daily driver up until a couple months ago. But since I still have it, still pounding through with Travis' LOS 15.1 build, I can trade some instability for testing if the outcome is having a few shiny updates.

I had my eyes set on finding a way to make this phone compatible with Project Treble. The only bit of information on that was Travis mentioning he had to remove the blobs(?) for it due to not so well versed folks screwing up their device. But I had hoped that would be revisited at some point and maybe even get the K20+ running GSI roms... Then finding out even if it could be set up, I believe it would require advanced repartitioning to get A/B boot which might just be problematic if not plain impossible. Haha I may have been a tad optimistic on that end.

I know the thread is kind of dead, but has anyone been able to get the hotspot to work? Whenever I turn mine on, anything I connect to it says "Connect, no internet"
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] mario0318:
Your phone plan very likely does not include hotspot/tethering data allowance. You'll have to either add that service to your line

orrrr...

You can give PDAnet a try (I works perfectly, without time restriction if you purchase the premium app lifetime license, which is absolutely worth it. You can find the apk in the Play Store or if you're de-Googled there are lots of sites you can download the apk from.

The only issue you will have with using PDAnet is the method of connecting other devices to your hotspot. If it's Android to Android the best method would be using the app on both devices. There's also a Windows program for Android to Windows connectivity. Otherwise you'll have to do an instructed method via proxy which works fine for most devices but not with devices lacking an interface to create or modify network connections. The app and website goes into detail about all this.

The best thing is it literally and reliably without missing a beat truly conceals all tethering from the carrier and is counted towards your regular mobile data. Be sure to enable to option to hide tethering from carrier.

Sorry for the noob questions but do I flash the .zip file or do I extract the .img file from the .zip to flash the rom from PBRP? And if installing the .img file in PBRP, do I flash it to the boot partition, the system partition or the modem/firmware partition? Also, is there a minimum GAPPS variant that should be used?

[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] esckey:
Just curious, is the fingerprint scanner something you know how to fix & just haven't implemented yet or do you just not like the feature?
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] Travisholt92:
I'm not giving up on this project until this phone gives up on me lol.
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] Travisholt92:
The fingerprint scanner isn't implemented yet because it is going to take a lot of shim scripting to get it working. I don't plan to work on it until after I get pie running and stable
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] esckey:
Makes sense, it seems like it would be something annoying to get working properly. Its not a make or break feature for me, was just curious, thanks for filling me in.
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] Travisholt92:
I'm with you there. That's why Oreo has been my daily driver since I got the hotspot working lol. You're welcome

Just letting you know I'm still here, I uninstalled telegram for a few as it was constantly telling me to read lol
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] Travisholt92:
Can't blame you there. People constantly blow that stuff up. But there is a mute notification feature built in too. I mute those chat rooms quite often for that very same reason. Threatened to ban a few people from the groups for sending so many messages in a row. They get too carried away at times. I keep my phone on silent because of it....

It's getting closer guys, I have a feeling its just something simple now

K20 losing steam?

I've been trying everything on it ..

it's a secondary ..

so if i can't unbrick a bad decision...

I won't be at a loss...

I'll keep throwing everything at it ....

My primary is a aristo 1 ....

Been waiting to see whispers become reality for that phone...

Please keep up the love...

Just until I get my new rig, I'm working on trying to migrate from GCC toolchains to Clang for the kernel. Once I get my new desktop I'll be bringing up Pie, There are already a few Aristo 1 builds with Oreo but none are public yet.
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] hawknest:
Does anyone have the DAMN At&t Variant Oreo KDZ ?? Evidently the At&t one received Stock Oreo and I can't find it anywhere
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] Travisholt92:
AT&T doesn't release KDZs, if it's VoLTE related the one from Q6 or stylo 4 should work.
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] Travisholt92:
Next build will have the kernel and ROM compiled with DragonTC Clang 5.0(for now, this was just a trial run to get the ball rolling on clang. I don't think this rig can support clang 7.0 since my rig failed to compile it) and the APN fix baked in.

I'll hopefully have a new ryzen rig within the next 2-3 weeks then I can go hard on some DU pie.

I have someone else willing to compile Lineage for me, but I'm aiming for Official DU, with the current stability, it think its very possible that this will happen. Hopefully we'll be able to support android Q without having Vulkan API support or maybe even add vulkan API support.

[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] hawknest:
I'm still stuck at the same point with the Volte situation.. I'm 99% sure its modem related
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] Travisholt92:
Indeed it is, because of how LG scripted it. It will require reverse engineering the stock ims , telephony, and misc frameworks. Its a bit over my head. I dug deep into it but got nothing but confusion and bootloops lol
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] hawknest:
I mean I have the knowledge to do it, but its going to be a lot to do for Oreo and then redo it for Pie if thats still in the works.. How is that going BTW.. And yes I do have hangouts ill pm you my info

It's locked in the modem and not the OS, you must have switched to one T-Mobile based like metro PCS or bought the device used unlocked by the previous owner.

DragonTC is a no since my desktop can't support using newer toolchains, but I did get Clang 5.0.3 support compiling even with the -werror flag which treats warnings as errors. It only took 1 commit to support official clang over DragonTC which removed the -werror flag. Making a new build now to ensure this kernel works. If all goes well I'll have a new build out tonight

[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] Cyconumnum:
I noticed that......the audiofx thing ...

you flash any sound mods ..

the phone has trouble deciding which one to use...

I flashed viper and it worked every other reboot ...

and if i decided to just rock audio fx with the other various mods off...

audio fx only worked when its open on the screen...

then stop working if i opened anything ..

or closed it without stopping it...

Dolby does the same...

It sounds awesome without mods anyway..

Audio fx is not all that bad...

Specially if it's not broken to begin with.
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] xda general:
Did you try freezing the audio fx app with lucky patcher then flashing audio effect remover the reinstalling dolby and viper?
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] Cyconumnum:
No....i just wiped and flashed the whole OS and left it to see if audiofx was acting up by itself..and just left it alone
[LG K20 Plus ROMs, Kernels, Recoveries, & Other Dev] xda general:
Hey i got ainur auron and viper4a working on ?????

What i did was first flash ainur from magisk then viper and then audio compatibility patch and then audio library modifications patch then rebooted

After that i realized that when the audio fx app is on it stops viper from processing but it doesn't stop ainur tho. So all i did was use lucky patcher and freezed audio fx and then wa la ainur and viper working together system wide ??

Oh and double tap to wake works on this rom but just not fingerprint. Oh and i realized that whenever i set a lockscreen option from anything else other than none it takes like about 3 minutes to wake when the display is off but setting the screen lock to none fixes it. Travis please finish this rom because it is the fastest and smoothest custom rom on this phone so please see what you can do about the few bugs.

I had it working when I first had Oreo booting but dropped it because it causes too many problems with the ROM users messing things up and not understanding how to add/remove the vendor partition after creation and reverting back to stock before removing the vendor partition and soft bricking their devices. Never again.... But yes it is 100% possible because I've done it. Thank derps and derpettes for me dropping treble support lol. And this is why I have a beta test group, XDA has wayyyyyyy more handi-capable individuals than my test group has, and if they screw things up, XDA users will surely screw it up even worse.
