I have an H915 model. It was on oreo so I downgraded to 10e to root and get TWRP. I got to the part where fastboot is now working on the phone but when step3.bat runs, the boot image does not get flashed with the error, fastboot: error: Couldn't parse partition size '0x'.

After this, because of step3.bat script the phone reboots and it shows a blue screen with something about lge error. It says I can reboot by holding volume down which I did and then it shows the LG logo then the whole screen goes static. As if the LCD is broken (but really, it's not since everything displays correctly, on logo, fastboot, and the factory reset screen. I read somewhere that the kernel is the reason for this but not sure. When I try a factory reset, it also does not go to the TWRP screen rather, it just boots to stock recovery with the recovery also showing static. My only option is to go back to fastboot or should I reflash stock and try again?

EDIT: Turns out I missed a crucial step on the root guide on the 2nd post. The original root guide explains flashing the WW kernel along with TWRP but I don't need that since I'm not keeping stock. I just let it boot after step3.bat ran fastboot reboot instead of taking the battery out instantly (I missed this part completely. got confused while following the root guide lol) I successfully booted to TWRP, flashed the new one and also my backed up EFS. I'm attempting auto debloat now.

Hi,

the explanations for rooting and installation are well described. It's been a really long time since I rooted a phone so this really helped me.

I recently bought an LG V20 mainly to listen to music. I'm intrigued to test the "high impedance mode" to see if I have a gain in the sound quality of some of my headphones/iems. I know that the opinion on the subject is very divided but I was wondering if there was a simple way to activate this mode in your rom?

By the way, the rom is pretty fast and the battery efficiency is really impressive.

Thank you!
[LG V20 Themes, Apps, and Mods] AmbitiousMine:
Oh my bad, I should have done a little more research before I asked.

I'll make up my own mind but out of curiosity, is this something you've tested?

Thanks again!
[LG V20 Themes, Apps, and Mods] AmbitiousMine:
Good point! I heard about this app. I must check this out. Thanks for all the help and support, it's really appreciated.
[LG V20 Themes, Apps, and Mods] dextructor:
This behavior it's happening for more than 2 weeks on my devices, but since I try to relay as minimum as possible on Play Store apps, I'm ok so far.

The problem with APK Mirror it's they don't have as much apps (and older versions if you wanna try because whatever reason) but yes, thanks for the tip.
[LG V20 Themes, Apps, and Mods] dextructor:
I like my music collection as well, but since this is the first smartphone that I got that have an DAC, I'm lost on what a good player options are available on the market.

Really good initiative of yours, but let me ask: Why you wanna build an CLI on Android? I'm all in favor of minimalism and use less resources as possible, and I don't mind using CLI or TUI on my Linux desktop.

I'm really curious about your approach.
[LG V20 Themes, Apps, and Mods] dextructor:
I have my collection of FLAC's and I don't believe that I have anything above 16bit, because when I ripped/acquired when anything beyond 16bit was somewhat dubious of tangible advantages.

In Linux I like to use mpd+ncmpcpp-ueberzug and I understand the appeal/simplicity.

I never really have the chance to live the bbs era, but I played once or twice.

Probably this Sunday I will test your script, any special instructions or requirements?
[LG V20 Themes, Apps, and Mods] Whosondephone:
Finally got around to testing your debloat script. It's awesome! I waited too long to try it out. The only thing I don't care for is the color calibration.

Would you kindly tell me which file gets modified with the new color profile? Or tell me what to look for in the script? Or is it part of the update binary? Thanks.
[LG V20 Themes, Apps, and Mods] Whosondephone:
Hey Darnrain1, I just updated my VS99520d ROM. I really appreciate your feedback from last time. Could you take a look at my hacky work? Can you give me any hints as to how other developers created the partition scrips? Or working with TWRP in general. Thanks. You are the best!

I tried to DM you but it didn't work for some reason.
[LG V20 Themes, Apps, and Mods] monc1975@yahoo.com:
You probably took the v20 as far as it would go on oreo, hanging the boots up isnt a bad idea. Thanks for your efforts. Ill check out your github, looks interesting
[LG V20 Themes, Apps, and Mods] dextructor:
Thanks for the contribution. I tested on my spare V20 and works really great.

Just wished that Android 9 worked so flawlessly as you made Android 8 on our devices.
[LG V20 Themes, Apps, and Mods] dextructor:
Touche, indeed many manufacturers chosen this path (remember Apple updated that slowed down iPhones > Class action lawsuit > Apple admitting certain guilt and paying some money to go away) .

Thanks for your time and dedication on this project.
[LG V20 Themes, Apps, and Mods] stingbandel:
You mention on the first post about miracast not working. Could u explain more? And also can I run your file now.that I have installed all apps? Or it needs to be clean install? Thanks
[LG V20 Themes, Apps, and Mods] dextructor:
I have a question related to music players. Did the Stock LG Music offer also 24bit playback as well? I use Auxio as a main player since going FOSS

Other question related to the camera. I read about the improvements and for what I could remember that's the library enhancements that was ported from Android 7 to 8.

But I also remember on the SuperROM that it have a option to install the V30 camera app + enhanced libraries. It was really better(the V30 app)? You think that's worth?
[LG V20 Themes, Apps, and Mods] dextructor:
Do you mind sharing how you test methodology, please?

I was only curious about what the v30 camera app could have any improvements over the stock v20. The challenge on GCam it's to find a good config files that can produce a good image and work with the lenses correctly. I found this folder on some Telegram channel with some options, but I didn´t test it. But thanks for trying porting the v30 camera app.

Regarding EQ I personally don´t like to tweak as much because I believe that in most cases there are higly competent audio engineers on the DAC side and some on the music productions that designed the music to be listened in certain ways.

But as any form of art, it's highly subjective to personal taste and on how you choose to appreciate, and if anyone likes to tweak with EQ or any "enhancements software"... More power to you.

I remember reading early about the Maximizing of bass, but I think that you edited that latter today, that it's on the speaker only or it would be applied to the DAC as well?

The 24bit system wide it's something that it's exclusive on the LG Stock ROM or can be replicated on AOSP?

Thanks

So can we update magisk 26.3 on h990ds or it only works on h910? Thanks
[LG V20 Themes, Apps, and Mods] stingbandel:
So whats the step to install magisk 26.3? I just uninstall 24.3 app then flash your lemondrop on twrp? Thanks
[LG V20 Themes, Apps, and Mods] stingbandel:
I did that but the phone hangs after that. Only 24.3 works on h990ds…
[LG V20 Themes, Apps, and Mods] stingbandel:
Hi, I manage to get magisk 26.3 running on my h990ds but when trying to hide magisk app, it fails. It just hangs on that mask logo. Can u hide magisk app on your phone?
[LG V20 Themes, Apps, and Mods] stingbandel:
Now speaking of lemondrop. Since I am.back to magisk 24.3. If I want to install lemondrop I just flash it on twrp? Also what abiut if I would like to remove it just because there's something wrong, do u provide somekind like uninstall feature? Thanks
[LG V20 Themes, Apps, and Mods] stingbandel:
Since I already on magisk 24.3.then I just flash your file.on twrp? No need to downgrade or.anything right? Thanks
[LG V20 Themes, Apps, and Mods] stingbandel:
Is it possible to have the bluetooth LDAC audio codec playback quality setting on developer options to be set at 990 kbps instead at best effort? Because when I set to 990 kbps the sound is way much better on my Sony headphone. But I need to do it manually everytime… thanks
[LG V20 Themes, Apps, and Mods] stingbandel:
Thanks… bluetooth codec changer is not compatible with oreo. I'm gonna try with sony one… will let u know the output later… .
[LG V20 Themes, Apps, and Mods] stingbandel:
Update: sony app cannot do it. The bluetooth codec changer can do it on my other phone that runs A13. Really wish the bt codec changer supports oreo… .
[LG V20 Themes, Apps, and Mods] stingbandel:
Hi, is FM radio working on yours? Mine is working only on speaker phone. It's not working on my wired headphone… mine is h990ds… thanks
[LG V20 Themes, Apps, and Mods] stingbandel:
6.2 universal…
[LG V20 Themes, Apps, and Mods] stingbandel:
Update, not only fm radio.but all will not be working if we dont set the quad dac on. When the quad dac off no sound coming out from the wired headphone. So.basically we need to turn on quad dac to get all sound coming out.

Now my question, is it.possible to also have the sound coming out with the quad dac off? Thanks
[LG V20 Themes, Apps, and Mods] stingbandel:
Hi, yes, the fm is ok now as long as the dac is on… so can u do without the dac on, the sound is also on? Or u have everything through dac? Thanks

Do u still need the rom? Here if u need one

[Rom][Oreo][Rootable] H990DS 20a, 20b [AME][IND][TWN] flashable

Hey Guys Here's the rootable H990DS Oreo flashable ROM based on AME, IND and TWN I have NOT tested this ROM on other regions but it should work. I've also included the patched raw_resources.bin to prevent showing the corruption warning at the...

xdaforums.com

The IND one…
[LG V20 Themes, Apps, and Mods] dextructor:
After spending many hours only trying to boot my H990DS I finally could bring a working method, so anyone please feel free to reference it in case of problems installing.

1. First download the five required files.

H990DS TWN 20b ROM from this Thread

ezV2020 kernel for Oreo

Magisk v21.4

TWRP 3.2.3-4 H990

Lemon_Drop_Hi-Res_v6.x_universal_Lgv20_flashable.zip (v6.4 at this moment)

2. Then copy the five files to your micro sdcard

3. Reboot into twrp

4. Click Wipe

5. Format Data Partition (this will erase your internal storage on the phone)

6. Click back and reboot into recovery again. aka twrp

7 Flash in order

A. TWN20b ROM

B. ezV2020 Kernel

C. Magisk v21.4

D. Twrp (The twrp img file you can flash with twrp you just need to select Install Image, select the file and choose recovery)

E. Lemon_Drop_Hi-Res_v6.x_universal_Lgv20_flashable.zip

8. Reboot into system, run setup

With a newer TWRP I got many random errors flashing, sometimes the ROM stuck at flashing system, other times the ezkernel had errors identifying the correct Android version and didn't install at all. With this TWRP 3.2.3-4 version, I can install 10 times without worries.

My problem with the Magisk 24.3 at the step C of flashing, it's wthen you finished flashing all and finally reboot the device it goes after a few seconds to the fastboot mode, and no matter what, you won't go to system. So install the 21.4 > initial device setup > Download the latest zip version of your choice (I'm using Canary 26401 at this moment) > Reboot into TWRP and flash it as usual > Go enjoy Lemon Drop.

I still need to download Poweramp, but from what I can remember it was a little daunting, non intuitive app from many years since I tried.

@Darnrain1 do I need to tweak out-of-the-box this app so I can fully experience the tweaked DAC and other tweaks? Change what settings etc?

Thanks!
[LG V20 Themes, Apps, and Mods] dextructor:
No problems, I'm glad to help. I just don't wanna others to have so much problems that could be solved by other members documenting their findings. Finding the correct versions, testing again and again until produce the right results.

Since I don't use gapps (because don't need/don't care anymore) and specially SafetyNet I don't need to hide anything, but that's a great advice... Thanks! I'll de-Google my device when I'll have more time to play with it.

That's I'll do next time that I will have a few moments to play with my H990DS and turning it to this HI-Fi dedicated device thanks to your rom.

Thanks for the tips.
[LG V20 Themes, Apps, and Mods] stingbandel:
Ok. This is very clear now. Thank u sir…
[LG V20 Themes, Apps, and Mods] stingbandel:
Question sir, when u use the latest canary, can u hide magisk? Cause latest stable 26.3 cannot hide magisk. Thanks
[LG V20 Themes, Apps, and Mods] stingbandel:
Wow… you are so dedicated with this… thank u… . I will update after this. So there is no way to enable the sound when the dac is off right? Just asking. Not too problem for me. Just asking. For the bluetooth codec also no way to set it up unless using the 3rd party app. Too bad the app cannot support oreo. I emailed him and already got the replied that it would be for A9 upward…
[LG V20 Themes, Apps, and Mods] stingbandel:
Hi, thanks for looking at bluetooth. For dac off, I was just asking. Ingone it… . anyways, I would like to know what kernel do u use? I tried mk2000. It feels faster but tends to get hot easily. Currently back to ezzony one. What do u prefer for kernel? Thanks
[LG V20 Themes, Apps, and Mods] stingbandel:
I use ezonny 1.2. It should be ok or I have to.go back to 1.0
[LG V20 Themes, Apps, and Mods] ShazamMan:
Okay dokay. SIM card was already removed from the start though, but not the microSD. I'll try that and re-do PARTITION DL one last time before I attempt a factory reset.
[LG V20 Themes, Apps, and Mods] ShazamMan:
Yep, the phone is still plugged in after it restarts from LG UP. I doubt it's the cable, considering I can see both on the LG UP window and my phone's screen that files are being flashed during the PARTITION DL process.

And looks like the phone still hangs at the LG logo after I do PARTITION DL even without microSD, with everything checked or with laf unchecked.

I'm about to do a factory reset now. Fingers crossed.
[LG V20 Themes, Apps, and Mods] ShazamMan:
Factory reset did the trick! I got the Android setup screen (as seen in the video) and can confirm I have H91510e on my H910.

Time to resume the root guide now.

But wow, I might be the first person who got into this issue despite following everything correctly! Thanks dude, your solution solved it!
[LG V20 Themes, Apps, and Mods] ShazamMan:
Hmmm. I opened two CMD windows as instructed. I ran the dirtysanta command but nothing shows up afterwards. Is this normal? Could I proceed to run STEP1.BAT now?

My device is detected, as seen in the above screenshot.

I put the contents of h910_root_pkg.zip in the platform-tools folder so I can run my adb commands from there. Looks like this:

By the way, I swapped h910_root_pkg.zip's TWRP 3.0.2.1 for TWRP 3.3.1-0 and edited STEP3.bat to flash TWRP 3.3.1-0.

Edit: Yes, I did install ADB Installer file (adb-setup-1.4.2.exe) from the guide. But I also downloaded the platform-tools v4.55 for Windows. I put contents of h910_root_pkg.zip in that folder.
[LG V20 Themes, Apps, and Mods] ShazamMan:
Never mind, I got a different ADB installer and got to STEP3.BAT.

Phone rebooted into bootloader (small text, FASTBOOT MODE).

However, I'm getting <waiting for device>. Any idea? All drivers installed.
[LG V20 Themes, Apps, and Mods] ShazamMan:
Okay, I found this comment:

This user is right because I'm getting this:

My LG driver is the latest from LG website (4.8.0). I'm trying to reinstall 4.2.0, but:

I'm in FASTBOOT now. Could I unplug the USB cable and put it back, then run STEP3.BAT? Maybe the driver will get detected. If not, how could I uninstall Driver 4.8.0 from the computer?

EDIT: Uninstalled Driver 4.8.0 with CCleaner. Reinstalled Driver 4.2.0 but still getting <waiting for device> after STEP3.BAT. Again, should I unplug the USB cable and put it back at this stage whilst my phone is in fastboot?
[LG V20 Themes, Apps, and Mods] ShazamMan:
Right-clicked on the Android icon in Device Manager and uninstalled it. Now remove the cable and plug it back while still in fastboot, correct?
[LG V20 Themes, Apps, and Mods] ShazamMan:
The installer from that fastboot access guide solved it! When I re-plugged in the phone, the Android icon in Device Manager disappeared. Now I have TWRP 3.1.1-0 on my screen!

Time to do some wiping and formating, rebooting in TWRP and then flashing H910_20g_Oreo_full_rooted.zip and Auto_Debloat_H910_20g_only_v9.1_flashable.zip in that order.
[LG V20 Themes, Apps, and Mods] ShazamMan:
Flashed them both (followed your guide), but after rebooting the system (with some weird visuals), I see the Secure Start-Up (25/30 attempts remaining) screen again. Did I miss something?
[LG V20 Themes, Apps, and Mods] Preparedtobereckless:
Thank you for your work
[LG V20 Themes, Apps, and Mods] stingbandel:
Since ver 6 the audio quality is already good. Now u have 10.2 and I just install it… but for bluetooth that codec changer is quite important. I do notice the quality different after changing the codec. Too bad no app can do it automatically on oreo. I am ok with manual setting… .
[LG V20 Themes, Apps, and Mods] Preparedtobereckless:
Does this mod have the boosted Bluetooth sbc bitrate?

Also I know you don't agree with viper4android due to output fidelity but I was wondering if your mods make it impossible to install without customizing it due to moving of audio config files?
[LG V20 Themes, Apps, and Mods] fzhu052:
Just registered to say 'thank you!'

two problems I am encountering so far. Latest version I tried is 11.0.

1. FM Radio. no sound from headphone. Speaker works majority of time.

2. Tidal MQA format not working. now that Tidal enable MQA and FLAC both as 'Max', 24bit 192khz Flac works fine, but not MQA.
[LG V20 Themes, Apps, and Mods] fzhu052:
For FM radio, yes DAC was enabled before. once radio is on, it automatically disables the DAC.

For Tidal, DAC is always enabled and it works well for high resolution FLAC, but MQA is not working. My very uneducated guess is that the codec is not supported by your code.

Your tweak gives us endless fun and expectation :)
[LG V20 Themes, Apps, and Mods] fzhu052:
On 14.0, VS995. The FM radio is working 100%. Thank you!
[LG V20 Themes, Apps, and Mods] ezzony:
What changes for what effect did you make in the mixer_path file? Is it to enable high impedance mode or that and more?

I was wondering if anyone has been using ezV2020 Pie kernel on Oreo roms? They are available with high Impedance mode enabled in the kernel. I don't know if that would work and/or conflict with your Lemon Drop audio mods.

Also I was wondering if your audio mods could be ported to pie stock rom on the F800's.
[LG V20 Themes, Apps, and Mods] ezzony:
So the file to flash on Pie is the same one as used on Oreo or you made one specifically for Pie?
[LG V20 Themes, Apps, and Mods] ezzony:
fyi, tasha is tavil on pie
[LG V20 Themes, Apps, and Mods] ezzony:
Hi yes, I can see your "Experimental direct hardware 24+bit" mode active in poweramp audio settings.

Thanks for that :)
[LG V20 Themes, Apps, and Mods] Juleast:
Hi, anyone in Canada using V20 with this ROM confirm that they have working cell service? I tried a Canadian sim but it just keeps showing some AT&T service blah blah.
[LG V20 Themes, Apps, and Mods] RudyUrbina:
Installed on my H990DS and it's working great, sounds amazing with my salnotes zero, only thing that doesn't work is fingerprint unlock, not sure why but it's not appearing as an option and when I search for it in settings, nothing comes up
[LG V20 Themes, Apps, and Mods] QkTreasures:
So could I install this Rom on a Tmo H918 with Stock Android 7 Rom? Also I would probably need to unlock the bootloader. Is that even possible still? Thanks Ron. :)
[LG V20 Themes, Apps, and Mods] QkTreasures:
With this Rom should most features work on H918 like 2nd Screen, DAC, IR Blaster & VoLTE/Wi-Fi calling?
[LG V20 Themes, Apps, and Mods] QkTreasures:
So would FM radio work on H918 LG V20 T-Mobile along with IR Blaster? Also how is battery life on this Rom?
[LG V20 Themes, Apps, and Mods] QkTreasures:
Have you ever tried a Lineage OS Rom on your V20?
[LG V20 Themes, Apps, and Mods] LA2A:
Can you elaborate on this? Maybe something is just getting lost in translation, but it reads like you're applying EQ, which would be the last thing I'd want.
[LG V20 Themes, Apps, and Mods] LA2A:
Yeah, that's perfectly fine. You're obviously free to make any decision you want with your project. Just unfortunate for me, and maybe me alone... who knows. Seems like an odd decision to hard-bake an EQ into something when there are so many different devices/speakers/headphones that other people would be using that potentially would have a negative impact to their sound rather than a positive one.

For example, I primarily use a pair of Etymotic ER4SR in ear monitors with my V20. These IEMs are known for having a very neutral and flat frequency response. I would simply never want to apply any EQ changes to them to deviate from that analytical flat sound. Some people would! But there are songs that I enjoy on them that are notoriously sibilant in the S's from the female vocalist. So applying a treble boost is not a positive change at all in that scenario.

I think the option to have it is a great idea for many people. But to bake it in seems like a bad idea. I wish you the best of luck and hope you enjoy your project. Take care.
[LG V20 Themes, Apps, and Mods] AmbitiousMine:
Thanks for all the work. When you say that all versions do include treble, does it mean boosted trebble? I'm curious because I use an IEM that are tuned with clear treble. :)
[LG V20 Themes, Apps, and Mods] AmbitiousMine:
Perfect, I will try the treble version than. Thanks for the clarification!
[LG V20 Themes, Apps, and Mods] AmbitiousMine:
Deleted
[LG V20 Themes, Apps, and Mods] iocast:
Nah, you're not the only one here after a perfectly flat equalizer. Correct me if i'm wrong but the phone has no DSP(same as all phones), so any changes in the equalizer are software implemented. That means that it may sound ok in one system and completely crap in another. And i won't even dive into the discussion about the quality of software based equalizer.....
[LG V20 Themes, Apps, and Mods] AmbitiousMine:
I just plugged my hungriest headphones on paper (120 ohm) and i have more than enough volume for it at 50. I also have test 2 set of IEM and 1 headphones (all planars and they benefit from high impedance mode) and it is pretty loud at 40. The treble version sounds really good, thanks!
[LG V20 Themes, Apps, and Mods] AmbitiousMine:
Hi, i use apple music player with your rom and the audio quality is set at 24 bits, 192 khz. Do I get the same quality as I would get with a player like poweramp?
[LG V20 Themes, Apps, and Mods] AmbitiousMine:
I will try this version tomorrow and compare it to my dedicated headphone amp and DAC setup. Cheers!
[LG V20 Themes, Apps, and Mods] AmbitiousMine:
I highly doubt it too but i'm happy to know there is a way to find out. I don't know much about Poweramp but I will try it for sure if Apple music is 16 bit. Thanks again
[LG V20 Themes, Apps, and Mods] AmbitiousMine:
Ok I run the command and I'm pretty lost. Do you mind if I share you the log?
