[LG V20 Guides, News, & Discussion] WTF?:
Works well - upgraded from 10F to 10L and kept my SuperSU 2.82 root. Sadly, the radio still sucks in this phone, the only thing bad about the V20, terrible reception in rural areas. Also, this ROM runs hotter, I need to figure out why, probably more background crap running.
[LG V20 Guides, News, & Discussion] nickthaskater:
There's no reason for it to run hotter. It's probably just the result of a fresh flash and having everything load up the first time.

What are you using to determine it runs hotter?
[LG V20 Guides, News, & Discussion] WTF?:
Using my finger on the power button - it is pretty hot, didn't used to be - but there also seem to be more apps/services running, perhaps I need to go in and re-kill them off

my us996 flash 10l lost signal, please help:crying:

and i can't flash back to WETA 5.0.7 rom . when finished flash rom , only can't stop reboot
[LG V20 Guides, News, & Discussion] dimm0k:
do you know if your device was a US Cellular variant of the LGV20 or was it the no carrier unlocked LGV20? also, who's your provider? it's possible that you had the latter version of the LGV20 and that the US Cellular variant doesn't work with your provider so you would need to go back to a no carrier unlocked LGV20 ROM, but I need to know what version and provider you have.
[LG V20 Guides, News, & Discussion] WTF?:
to get signal back - go to Settings ---> More ---> Mobile networks ---> Access Point Names ---> click the 3 dot menu and select Restore default settings :)
[LG V20 Guides, News, & Discussion] nickthaskater:
10L does bring back system apps like Mobile Services Manager, Instagram and Facebook, so yes, a clean would be in order after flashing. MSM definitely needs to get the boot as it can run and install things in the background. The definition of bloat and unfortunately it's on both the UCL and Unlocked versions of the 996 by default.

Besides that, the initial boot will definitely run hotter regardless. Mine stayed a bit toasty for a while after flashing but is back to expected operating temperature some days in now.
[LG V20 Guides, News, & Discussion] masktao:
thanks for relay . i thinks is not about provider. my us996 unlock bootloader official.it's about "radio off" (https://www.google.com.hk/url?sa=t&...72287/page/2&usg=AOvVaw1b0krWG-XF834biYOeMgqU)

i try to flash back weta5.0.7 can't to system.always reboot. i try to flash LineageOS. it's also no signal. i think baseband hardware switch is turn off

can u give a way to save back my phone signal :(

---------- Post added at 06:15 AM ---------- Previous post was at 06:05 AM ----------

thank u ,but it's not easy way. i try flash LineageOS. and it's also no signal . i think baseband radio hardware switch it turn off.

maybe i need reflash kdz or reflash baseband file. i never try before:(
[LG V20 Guides, News, & Discussion] nickthaskater:
Slow down and take a breath.

Flash back to stock with LGUP and a factory .kdz file.

Do the usual steps of unlocking, flashing TWRP and Magisk, then flash the 10L .zip from the OP and immediately flash Magisk again after that (do not reboot in between).

Curious, why are you messing around with WETA and LOS when this is a thread about stock 10L?
[LG V20 Guides, News, & Discussion] WTF?:
Yes temperatures have gone back to normal - I would PAY A BOUNTY if someone could solve the weak reception in rural areas - other much cheaper phones will get 2-3 bars on the same carrier in the same location where this flagship will only get 1 bar or none. :( It is not the soft TPU case, I have tried the phone with no case. I have a cool app called Signal Check Pro that tells me the exact Db of signal I am getting, so it is not imagined!

This is the only fault I can find with LG V20
[LG V20 Guides, News, & Discussion] nickthaskater:
Stick some tinfoil in the end caps? Ha. I would assume it's just a limitation of the hardware than anything else. It's a common complaint across all variants of the V20, it seems.
[LG V20 Guides, News, & Discussion] masktao:
until unlock bootloader i always use weta 5.0.7, but there is no update ,so want to update to other new rom.

i found 10l can't open some app. Zombie Gunship work fine on weta5.0.7. but on 10l it's always can't open also some other app

i will reflash kdz later ,hope everything ok
[LG V20 Guides, News, & Discussion] WTF?:
If my new unlocked US998 V30 doesn't have better rural reception than this, it is going back!

Already pissed that they removed the most important AT&T LTE band (17) and replaced it with useless bands 1 & 66 :(

There's nothing wrong with 10L; it's your phone.

What is fastboot flash tz? It should be fastboot flash recovery.

Also, what is "tz_COM318"?

I think you need to go back and learn the process again as it looks like you're doing all sorts of things that are out of place.
[LG V20 Guides, News, & Discussion] WTF?:
when you run your battery down below 20%, you kill its long term life - maybe not such a big deal on this phone, but you need to correct bad habits, because V30 battery is not modular :eek:
[LG V20 Guides, News, & Discussion] nickthaskater:
Good thing it's a V20 and not a V30. :)

I use my phone the way I need to use it. I'm not going to stop just because it's low on battery. 20% is a hell of a lot of use left sitting on the table.

What the hell are you doing fastboot flashing all those bootloader files for ? You are just asking for a brick.

I see above that you typed: "fastboot flash twrp.img" - That is WRONG.

This is

[LG V20 Guides, News, & Discussion] tealcomp:
Big Thanks for This!

I did click the Thanks button, but that seemed so trivial. I wanted to say thank you in a more meaningful way; I am a US996 owner and prior to researching this post I was ready to chunk the phone in the trash (or likely sell it). Following these steps though I am now running with the latest security updates and couldn't be happier. If I can provide any kind of testing assistance please let me know; I would love to see Oreo on this phone when it becomes available.

[LG V20 Guides, News, & Discussion] askermk2000:
What makes you think that will fix anything? You already flashed US996 Unlocked KDZ with LGUP - Meaning ALL bootloader partitions where overwritten.

I don't know what the problem is, but other people don't seem to have difficulties.

Someone has already given you solutions. Look back in the thread.

You made backup with LGUP before flashing 10L ?
[LG V20 Guides, News, & Discussion] masktao:
yes ,when i use lgup flash kdz. twrp was gone. that' not matter. i use lgup flash back old KDZ ,i think maybe the Singal can be back!!!

but 10f also no Signal

now ,i don't care use which verson rom or kdz , i need save back phone signal

i found a modem.bin file. but now my phone can't flash this file or other:

fastboot flash modem modem.bin

now i need some way to can be flash modem.bin?

how can relock bootloader?
[LG V20 Guides, News, & Discussion] vlad48:
Please understand: If you lock bootloader - you can not flash the modem or any partition!

Simplified solution:

Make sure you are DirtySanta bootloader unlocked (when your V20 powers on you got a screen with exclamation mark)

Flash via fastboot the international modem

fastboot flash modem modem.img

Hi mate little answer for me... Where i found advance settings on 10L? Im facing issue with ir blaster... Didn't work after upgrade... Im trying to solve this issue..

[LG V20 Guides, News, & Discussion] masktao:
i'm not use dirtysanta bootloader unlocked. i'm unlocked official. and now use weta5.0.7 rom already root

so i don't know why u let me use dirtysanta to unlock bootloader ? it's better power than official unlock?:confused:

or it's can be writhe modem partition in unlocked state
[LG V20 Guides, News, & Discussion] vlad48:
Simple answer - Dirty Santa uses engineering aboot which allows you to manipulate all partitions while official unlock uses normal one which limits partitions you can tamper ;)

Again, be aware that you are very near to brick your device by flashing wrong modem!
[LG V20 Guides, News, & Discussion] Black6spdZ:
which image is this modem pulled from?
[LG V20 Guides, News, & Discussion] vlad48:
Extracted from US99610g - BPT region.

Works well and compatible with all US996 models also can be used if you want to convert your US LG V20 to Korean models (F800k/l/s) ;)
[LG V20 Guides, News, & Discussion] Black6spdZ:
do we know what bands or lack thereof for comparison? I extracted the 10l modem and flashed it on my unlocked us996 in twrp with no problems.. I would assume this is ok on a us cellular model as well?
[LG V20 Guides, News, & Discussion] strifej:
I finally took the jump and it seemed to have gone bad. Stuck in bootloop and can't get into recovery. I do the vol down + power to get the factory reset question twice, but it just reboots and doesn't go into recovery.

In fastboot mode I can't flash TWRP anymore (device is locked) so it looks like I lost the dirtysanta exploit?

Do I have to use LGUP and reflash f and start over?
[LG V20 Guides, News, & Discussion] nickthaskater:
No idea, sorry. I unlocked with the official LG method. I had no issue flashing 10l from 10k.
[LG V20 Guides, News, & Discussion] strifej:
I see. Just a suggestion, but if you have a different phone model and you haven't seen any other confirmations otherwise, please let the person know instead of saying just do it. Thanks.
[LG V20 Guides, News, & Discussion] nickthaskater:
Different phone model? This thread is for the US996 - I have a US996. I can't be held accountable for others not reading.

I just received the US99610n OTA update for my US996 unlocked phone. Since I'm rooted, I can't just install the OTA. I'd like to update to the latest security patches, but I'm not familiar enough with the LG V20 to know how to proceed.

If someone more capable is willing to work with me, I can get them the dlpkgfile and perhaps we can update the TWRP zip installer to 10n specifically for the US996 unlocked.
[LG V20 Guides, News, & Discussion] Parasol_Monsters:

[LG V20 Guides, News, & Discussion] nickthaskater:
You're the hero we need. Thank you :)

Any confirmation of 10n including the KRACK fix like UCL 10L?
[LG V20 Guides, News, & Discussion] solo2racer:
Thanks for the quick update to the TWRP zip files. I dirty installed it over my Magisk rooted system following the instructions you provided and it went smoothly.

Only hiccup was when it first came up, it tried to install the pending upgrade to 10n and said invalid version. Refreshing the "check for update" cleared the error.

It also listed "unknown version" for baseband and wouldn't connect to Verizon for a couple minutes, then the baseband version showed correctly and it connected. Not sure what was updating in the background (probably pulling down the latest NSA keylogger ;)), but it fixed itself eventually.

Everything is working properly, I have root access through Magisk and it passes SafetyNet check.

It's showing Android security patch level as November 6, 2017 which included the KRACK fix.
[LG V20 Guides, News, & Discussion] dimm0k:
the only thing I've noticed with 10n so far is that when I change my brightness to auto, it causes the device to reboot... can anyone else confirm this on their end?
[LG V20 Guides, News, & Discussion] storm68:
Negative
[LG V20 Guides, News, & Discussion] dimm0k:

Thanks for lot for putting this together [MENTION=5687667]dimm0k[/MENTION].

Do you mind to share the high level steps for putting this together?

I'd like to learn how to deal with KDZ files and converting them to flashable ZIPs, so I can try to merge the /system from other models (e.g. the Canadian V20) to create a build with wi-fi calling and other features.

Thanks in advance.
[LG V20 Guides, News, & Discussion] feretio:
The instructions were perfect and my update to 10n went well. Everything seems to be working as expected except my US996 is still prompting to do the OTA update. I've poked around the settings but where did you find the "check for update"?

Thanks!
[LG V20 Guides, News, & Discussion] solo2racer:
Settings -> About phone -> Update Center -> Software Update -> Check now for update
[LG V20 Guides, News, & Discussion] feretio:
Hi,

That's where I figured it'd be but the only options are "Continue update", "Check Automatically", and "Auto-install updates" (I attached a screenshot). Swiping down doesn't do anything nor does there seem to be any menus on that screen. Clicking on "Continue update" brings up a window wanting to install US99610n with the options: "Set Time", "Install Later", and "Install Now."

I'm not sure where else to look to force it to recheck for an update.

Thanks!

Signal problems

I'm having problems with us99610n I've lost HD calling and for some reason it won't switch to LTE and stay there other than that no other issues also on using Verizon. Do you think I can use my backup of us996l0l that I made before updating the phone
[LG V20 Guides, News, & Discussion] pistacios:
I'm reading lots of people are having this issue with 10n. I have read also in one particular comment that it did come back, but took some time...

I know this post is not much help, sorry.

I'm also on Verizon and have been reluctant to update due to this issue.
[LG V20 Guides, News, & Discussion] solo2racer:
I'm not sure what is happening with HD Voice and Verizon. There are two settings on the phone that I've found using the app QuickShortcutMaker.

com.android.settings/com.android.settings.Settings$AdvancedCallingActivity

com.android.settings/com.android.settings.Settings$AdvancedCallingSwitchActivity

The first is the one you get to through the settings and is greyed out and shows as disabled.

The second is not accessible through the settings. It is not greyed out, and was enabled by default. When I turn it off, it pops up a dialog box warning about disabling HD Voice.

So HD Voice may be enabled and the setting is a UI bug. Is there a way to tell if I'm using HD Voice during a call?

I also can't get into the service menu any more using *#*#4636#*#* It gives a message that it's not enabled on this device.

Overall, the radio in 10n does not seem as robust as in 10g. I wonder if I can reflash just the old radio and see if that works better. Anyone try something like that before?
[LG V20 Guides, News, & Discussion] nuke235:
Just want to know if anyone has flash from Weta 5.0.7 to latest 10N or 10L?

Did it go smoothly?

Currently on 5.0.7 (US996 10h), Unlocked w/ Official LG unlock w/ SuperSU 2.8.x

Im assuming just follow steps in OP, flash magisk 14, and if need be reset APN settings.

Is there anything Im missing?
[LG V20 Guides, News, & Discussion] feretio:
I have a rooted LG V20 US996. After I received an OTA notification that firmware 10n was available, I installed it using TWRP following this awesome thread (thanks dimm0k!):

https://xdaforums.com/v20/development/rom-us99610k-stock-rom-twrp-flashable-t3691784

However, I'm still getting the notification that my phone still wants to install the 10n firmware and can't figure out why. I'm presuming it already downloaded the firmware but not sure where it stuck it. Here's what I've tried:

- Cleared data for both System Update and FOTA in the App Manager in Settings.

- Cleared data for both System Update and FOTA with Titanium.

- Searched for "10n", "kdz" and other strings in /root using Solid Explorer.

- Cleared the Cache in Storage in Settings.

- Cleared the Cache Partition in TWRP.

- Turned off "Check automatically" in the Update Center in Settings.

Does anyone know where this update might be stored or how to get my phone to realize I'm already updated to 10n? I don't really want to disable the notifications because I'd like my phone to tell me when an update is available (even though I'll probably never do the OTA update).

Thanks!
[LG V20 Guides, News, & Discussion] daverup:
I think the issue is the difference between the "official" 10n for US996 Unlocked that LG has finally made available (after a year of NONE updates), and what [MENTION=5687667]dimm0k[/MENTION] was nice enough to create for us.

I really don't know how [MENTION=5687667]dimm0k[/MENTION] was able to build 10n for us, but I would suspect that new TWRP flashable packages would be needed to stop the LG Update notifications.

I am happy with the 10n created by [MENTION=5687667]dimm0k[/MENTION] and have disabled the LG updates app which did exactly NOTHING in the past year anyway. LG did not even provide security updates for a year.

The V20 was my last LG phone, due to their lack of support. The V20 was a nice phone, too bad.
[LG V20 Guides, News, & Discussion] feretio:
You're right in that it took a year to get the 10n update so for now, I'll freeze both FOTA & System Update with Titanium (no disable option in the Apps Manager) and keep an eye on XDA for future updates, if any.
[LG V20 Guides, News, & Discussion] pistacios:
This is the only indicator I see off to the right in the contacts list (I'm still on 10f):
[LG V20 Guides, News, & Discussion] dimm0k:
I can post the KDZ file, which is what LG Bridge downloads from the LG servers when you use that software to do phone updates. that's the same file I used to create the TWRP flash file.
[LG V20 Guides, News, & Discussion] feretio:
Jeez...freezing FOTA & System Update didn't seem to do the trick as after a reboot, I'm still getting a notification about the 10n update! Anyone have any other thoughts on what I should delete or disable?

Thanks!
[LG V20 Guides, News, & Discussion] solo2racer:
The specific file that contains the update is dlpkgfile. I think it was in /data/data/lge<something> but I can't look for it since I don't have it any more. Search for that under the /data directory and delete it.

---------- Post added at 11:14 PM ---------- Previous post was at 11:11 PM ----------

None of phone numbers in my contact list are in HD any more. So it's definitely disabled in 10n.

LG probably didn't get Verizon to test 10n before release so it's not approved for HD Voice. Not sure if I want to roll back or not. The exploit fixes in the Dec 1 patch update are considered critical.
