[LG V20 Questions & Answers] Whosondephone:
I'm having a very bad time trying to get my phone to download a large torrent directly to a USB org hard disk. so far I have added the following to the "perms" section under flud in the packages.XML file:

<item name="android.permission.WRITE_MEDIA_STORAGE" granted="true" flags="0" />

<item name="android.permission.WRITE_EXTERNAL_STORAGE" granted="true" flags="0" />

In doing so flud allowed me to set the download location to the drive. However it does not appear to have write access. Can someone point me in the right direction please?

Edit: As I suspected the preferences.XML has changed itself back.

Battery usage is way too high on my H910 after upgrading to Oreo, so I want to go back to what was originally on the phone (10m). I can't seem to find a download for the full 10m rom anywhere (i.e. including the system partition). 10L would also work, as I could just use FOTA to get it back to 10m. Can anyone point me in the right direction?
[LG V20 Questions & Answers] cnjax:
There are no kdz for the 910, you'll need to flash a custom stock based rom to go back to nougat
[LG V20 Questions & Answers] d-m-wilson:
I know, that's why I'm asking here instead of just grabbing it from lg-firmwares.com or similar. I already got it back to version 10R, but the battery issue still exists. That's why I want to take it back to 10M or 10L.
[LG V20 Questions & Answers] cnjax:
Again there are no files to grab from LG firmware they don't exist, hence why I stated that need to find a "custom" stock based rom. Unless your intention is to crossflash another variant's firmware on your device
[LG V20 Questions & Answers] d-m-wilson:
I really do understand that there are no files for the H910 available from LG. But there are H910 stock roms out there. I think most of them are dumps made with the LGUP tool. Anyhow, I followed the H910 rooting guide by [MENTION=3167089]runningnak3d[/MENTION] and thus have downgraded from Oreo (version 20g) to Nougat (version 10r). The oldest complete rom I have found so far is 10q. I'm just trying one last time to locate an older one, preferrably 10m or 10L.

Updating security patch

Hi everyone,

I have a V20 H990DS, UK spec and entirely stock (not rooted). My only problem with this phone is that the last security patch was Nov 2018 - is there a way of updating the security patch for this phone without having to root it and put a custom ROM on it?

If it would require rooting to update the security patch, does the Dirty Santa exploit work for this model and region?

Thanks

LG V20 h918 (T-Mobile) w/ MicroG?!

Hello, I am new to Custom ROM installation, however, I would like to give it a go. Looking at picking up an LG V20 for T-Mobile and installing the "h918" version of LineageOS 14.1 w/ MicroG.

Questions:

+Once 14.1 w/ MicroG is installed, will I be able to update to 17.1 while retaining MicroG?

+If an update is possible, is it OTA?

+Does LineageOS feature any support for the LG V20's secondary top Mini-Screen?

+If not, are there any apps that can make use of the Mini-Screen?

Thanks for any help that may be sent my way.

[LG V20 Questions & Answers] X_BlackBurn_X:
Hello everyone.

i am new here and i am sorry in advance if i did something wrong. i will come directly to the point.

model number: LG V20 T-MOBILE VERSION, H91820H, NON USA, Currently on oreo android 8.

we are not talking about any kind of roms kernels roots or anything here. just a simple question. " can this model's boot loader be unlocked ? like ever ? or not "

cause i have tried everything, when i say everything i mean everything. followed several posts on internet videos on you tube posts on XDA, tried using multiple PCs, multiple data cables, multiple drivers but for some reason i don't know what, this model's boot loader cannot be unlocked.

THE ERROR:

<WAITING FOR DEVICE> till eternity.

what i have done till now ?

1. lg drivers installed.

2. adb drivers installed with adb fastboot files.

3. updating legacy android adb interface driver, done.

4. went in to boot loader then connected the data cable and updated driver, done.

5. usb debugging oem unlock options activated, done.

6. restarted pc multiple times to update drivers, done.

we all know all it takes is 3 easy commands to unlock bootlaoder

adb reboot bootloader

fastboot oem unlock

fastboot reboot

but in my case i always stuck at 2nd command. waiting for device is shown and nothing happens.

then i ran command, adb devices>> it shows

List of devices attached

adb server is out of date. killing...

* daemon started successfully *

LGH9182bfc6bdc device

next i put the command, fastboot devices and nothing is shown i just go to the next line... c:\adb>

so this is for sure that my device is not connected to the fastboot.

now my only question is, can this device bootloader unlock or not ? so that i stop pushing my limits.

any help will be appreciated.

regards.
[LG V20 Questions & Answers] scorpio76r:
To answer your question, yes the Bootloader can be unlocked.
[LG V20 Questions & Answers] X_BlackBurn_X:
thank you for replying and letting me know it can be done.

i really appreciate it.

[LG V20 Questions & Answers] Johnblah123:
Thanks for reply!

For anyone encounter same problem (Lost signal / radio) with LG V20 after flashing / receive OTA firmware / update. Just follow the "[GUIDE] US996 no service/radio off after OTA/KDZ fix" on xda-developers. If you follow the guide and unlock Bootloader via DirtySanta, some steps aren't very clear, hints:

1. Disable Antivirus

2. When the guide mentions "type" something, it means typing into Command Prompt (unless mentions Terminal Emulator). Press Windows+R to open “Run” box. Type “cmd” and then click “OK” to open a regular Command Prompt. Type “cmd” and then press Ctrl+Shift+Enter to open an administrator Command Prompt. Make sure your device is realized by adb (just run RUNMEFIRST.bat, it will let you know).

3. If typing "fastboot flash boot bootbackup.img" doesn't work, try typing "fastboot flash boot C:\adb\bootbackup.img" or whichever folder contains bootbackup.img

Is my vs995 still SIM-Locked?

Hello,

I recently bought a vs995 on ebay. The seller said it was "unlocked". But upon inserting my SIM-Card the phone said "The SIM-Card is not from verizon wireless".

Confusingly I can initiate and recieve calls, but mobile data does not work.

Some infos:

The device's box was still sealed, so it is probably factory new

carrier: t-mobile in germany, so the frequency-band should not be a problem (checked on frequencycheck.com / carrier-compatibility/wwoGio/lg-vs995-v20-xlte/t-mobile-germany)

I tried every network mode (LTE/CDMA , LTE/GSM/UMTS, ...), still no luck

My guess is, that it is just a problem with the stock andoid. This wouldn't be a problem for me, since I want to run lineage on it anyways. But when I unlock the bootloader I cannot get a refund.

So my question is: What could possibly cause those problems and are they related to a SIM-Lock?
[LG V20 Questions & Answers] cnjax:
Sounds like the phone is an H918 check the about phone section to verify, if that is the case then you need to get tmobile to unlock or pay to have it unlocked thru an unlocking service. Also if it's an H918 be advised do not flash firmware for any other variant as you will wind up with a hard brick

Hello everyone,

Thanks for the advice
[LG V20 Questions & Answers] LightSwitchTTM:
the US variants (ex. US996) are better. they were sold straight from LG and you can unlock the bootloader via LG's website. it's recommended to flash a ROM like lineage since anything the V20 is running out of the box these days has a ton of security holes as it hasn't been patched since like 2018

I have a H910 upgraded to Oreo. The software version is H91020h. When the phone boots it shows an unlocked icon.

I want to install LineageOS 17.1 on it and am trying to follow the official instructions. I am not sure if my bootloader is unlocked.

By the way, the instructions point to this post on this site to unlock the bootloader. When I try to download the file, Windows Defender refuses, reporting "Trojan:Win32/Sehyioa.A!cl" in it!

I have also tried the method in this post, but I'm stuck on the link being down for DirtySanta root package.

Any ideas about what to do next?

sir i am going to have to ask you to put down the w1nd0w$ os , and back away as fast as you can. for your own sake.

or, you can also do a selective boot, remove the windows hard disk, put in a new hard drive (preferably SSD) and install linux mint 20.1 on it. later on if u feel the need, plug your _OTHER_ hd in, and at boot up use F12, or what ever your motherboard manufacture uses to get to drive select, then chose what OS boots.

under no circumstance should you keep your w1nd0w$ hard drive plugged in when u install the SUPERIOR os. windows does not like being subservient to superior operating systems. bad things happen. actually it is in the mobo bios. i am just having fun. but yes bad things happen.

do not leave old HD's plugged in when u install a new os

OR you could just bypass the antivirus that will ALWAYS give u a false positive on android developer files.

u already have the spyware installed? from g0ogl3? the spyware is usually recognized under the name android development suit, or some such product name. yeah. i guess you gathered i do NOT like ga@gle.

under mint software manager make sure u have all the fastboot, and adb stuff installed. i think there might be 4 things you do not need under those 2 searches. less is better.

there is also a few android stuffs in there to get.

free is good. FOSS is better. free foss organized, ready for you to download, prescanned for safety, and function-capability?

why r u still using w!ndoz?

I have an H918 running an older version of Lineage OS on AT&T. I've recently discovered that my phone will no longer be able to place/receive calls once AT&T's 3G network is shutdown in Jan 2022 as my phone+Lineage can't do VoLTE on AT&T. This really, really sucks as I love my V20.

As I don't plan on switching carriers, is my only option to purchase another phone? Perhaps run an H910 with a non-Lineage ROM based on a stock ROM? Suggestions?

Thank you for your time.
[LG V20 Questions & Answers] mainmast2:
I know this post is a month old but I'd like to clarify it. As I understand it any phone/ROM combo that supports Volte will still work. AT&T lists the V20 as working after the shutdown of 3G (with the stock Rom of course) on their list.
[LG V20 Questions & Answers] spaceb0b:
I'm using a h918 in Europe. Everything works fine except calls. Frequently the sound on my side will drop while people on the other side can hear me fine. This has been very annoying but I don't want to switch to an other phone. The issue persists on Lineage OS so I suspect it's either the modem firmware, hardware problem or just bad compatibility with h918 and European networks.

Would it be possible to fix this issue by replacing my motherboard with one from a H990DS variant (because that's cheaper than a phone)? What kind of problems should I prepare for? I assume the form factor of the mobo will be the same save for the extra sim slot and if not I can probably improvise around it. Will I also need to replace the actual antennas (in the top and bottom bars)? Are there any firmware or other problems that I should expect? Any reason not to do it or alternative solutions are also welcome.

[LG V20 Questions & Answers] V20-Owner:
Hi everyone, noob here! I have an unrooted V20 (T-Mobile) that for some reason got stuck in fastboot mode. I went to sleep while listening to a podcast and when I woke up it wasn’t turning on because the battery had drained overnight. As soon as I plugged it into its usual charger and pressed the power button it went straight into fastboot mode.

I’ve tried restarting the phone, pressing the power button for 30+ seconds, taking the battery out for several minutes, letting the battery drain again and using a different charger. Nothing has worked.

Whenever I try to get it into recovery mode (by pressing the volumen up and power buttons simultaneously) it only shows the IMEI number and asks me to press the power button in order to restart the phone, but if I do it it just goes back to the fastboot mode screen.

Several months ago I had considered rooting it but I never went through with it. All I remember was enabling oem unlock and perhaps usb debugging.

Has this happened to any of you? Is there any hope that it could be fixed and that my apps and data are still salvageable?

I would appreciate any suggestions. Thanks in advance!

Hi,

I have a us996, the bootloader is unlocked.

I have installed TWRP the latest version.

I have installed Lineageos, the latest version (19.1)

I have installed the lasted version of Magisk's apk.

I have tried renaming the magisk apk with a .zip extension and sideloading it. It did not work.

I have tried the self install method from within Magisk on the phone, which gives an error also.

I have tried patching the boot.img image that comes alonside the LineageOS rom here: https://download.lineageos.org/devices/us996/builds , patching it from within the Magisk app on thephone and installing it. It didn't work.

I am at a loss here, things have changed a lot since the last time I have used my V20, 2 years ago. Back then, you just flashed a supersu.zip file and you were rooted...

Can someone point to me what I don't understand?

Which model of V20 is most suitable for hassle-free trial of LineageOS?

Hello from a nub,

I consider buying a refurbished V20 to try LineageOS because the model has a removable battery and seems somewhat sturdy. I see F800S/F800L/F800K, H910 (H990N/H990DS) and VS995 currently offered on Aliexpress. Which of those is the most supported/popular among developers/easy to unlock & flash, etc.? I'd like a trouble-free experience, as it's been ages since I dealt with custom ROMs.

I'd also greatly appreciate a more general advice as to whether this is a good starting point to explore LineageOS and/or other ways of limiting my exposure to Google. My dealbreakers would be lack of warning-free call recording (it's legal where I live and essential for my work) or sluggish performance of Telegram and Firefox (which I also use as a background YouTube player with uBlock and screen off). An option to use some Google Play apps I've purchased would be nice but I could probably get by anyway, as V20 may end up not becoming my daily driver if the refurbished phone proves unreliable...

Many thanks in advance for any opinion re the above or anything I failed to take into account in my considerations.

Also feel free to redirect me to a more relevant thread, since it's my very first post on XDA forums.
[LG V20 Questions & Answers] dextructor:
I can only speak from my scenario and experience with both H990N and H990DS.

They are technically almost the same except the frequencies that they support that may suit you better on your own country, but for me at least the H990N was more stable than the other.

If you are planing to have any of the V20 variants, you should first check the models and frequency compatibility for your carriers on your country, but remembering that VoLTE won't work on any non Stock ROM.

I heard for users on this forum that the H910 should be a good variant, that isn't difficult or troublesome to unlock, so it's worth checking.

The LS997 it's the most problematic of all because of ARB that prevent from downgrading (so unless someone didn't upgrade pass exploit point, should be fine) and even so I wouldn't recommend it because if you need to restore KDZ probably you'll won't have luck finding the files etc.

The VS995 and US996 I can't say as much because I never talk with any owner of those variants and/or many problems I could find that would make my opinion on purchasing those devices.

But in general every variant once unlocked should have the same experience using Lineage (currently Lineage 21) and works great.

That's an whole can of worms that I particularly don't like and I use microG for at least 4 years or more, so 0 Google apps and or everything on my device.

You can use LineageOS for microG (they only built-in microG into Lineage for you don't need to do it manually) and it's a easy way to try for yourself what could be to use a "Google Free" ROM, it's benefits, limitations etc.

I use Telegram FOSS (there are plenty of other alternatives that I didn't had the time/energy/interest to test it) and the performance it's really fine for me, on the messages, calls etc. Even on a very large group/channel it's good for my usage.

I can't recommend using Firefox for youtube playback, because you'll drain your battery so much faster and isn't worth it the possible quirks. You also can use a hardened Firefox called Mull and it's great.

You can use NewPipe and if you like skipping in-video sponsors insertions there's Tubular (NewPipe + SponsorBlock) and LibreTube it's also a good (and even more private) alternative.
