[LG V20 Questions & Answers] Thinkpadfan:
Many thanks for your reply. Already prior to reading it I've decided that H910 is my choice and ordered a supposedly new item for a mere hundred bucks on eBay. Then I was seriously sick, now am back to read your kind comment and preparing to get my hands on the parcel that has already cleared customs.

Assuming the Chinese seller has shipped a new item, as promised, and as long as call recording is supported by LineageOS, I expect to be happy with the device. Meanwhile I am looking for a good XL battery+case combo to replace the back cover and fuel the old new V20, so any recommendation in this regard would be very handy as well.

Thanks again for your detailed advice..
[LG V20 Questions & Answers] dextructor:
Technically Lineage support call recording (if you live on a country that allow this) but I never succeed on enabling. There's a thread that flashing a zip could enable call recording, but I didn't tried.

So you'll need an external app to record for you.

I'm usually favorable to free and or open source apps in general, but I didn't had the time to search for and app to replace my current call recording app Call Recorder - SKVALEX that I bought many years ago and still works and updates. I don't know the current price.

I don't like big and bulky devices in general, but I can understand the appeal to have a more than necessary battery once in a while. I also struggled to find a reputable replacement in 2023 for the standard battery and I'm glad to found official new Perfine batteries.

For the XL Battery + Back Cover I found from the same seller the working link, so if you can purchase from their store I recommend it.
[LG V20 Questions & Answers] Thinkpadfan:
Thank you very much!

My phone is still on its way. Whatever the performance of its 8 y.o. supposedly new accumulator may be, I gather from your kind reply that Perfine batteries are the way to go if I want to keep a couple of spare ones to use with the standard back cover jic.

I'll definitely try your advice for the call-recording app should I need it. Meanwhile, on one Android 8 phone I am using the currently obsolete yet free Boldbeast recorder that's still available from the developers' website.

Thanks again for sharing your experience!
[LG V20 Questions & Answers] dextructor:
The good news it's the Perfine also makes "standard size" batteries as well. It's slightly thicker than the OEM, but with a little patience you can close the back cover without problems.

I'm using my v20 as a daily driver and I can't complain. I don't use any Google apps, or even Play Store apps, I only rely on F-Droid and most of the times the apps are really well optimized.

Other thing to consider it's that other than using Lineage 21 I also use Swan200 Kernel that out-of-the-box it's more optimized than the stock kernel, and if you want, there's a overclocked version to squeeze even more performance.

I was setting up an LG v60 for someone for this past weeks, and it's faster in some tasks but nothing that I really needed or say that the v20 isn't good.
[LG V20 Questions & Answers] Thinkpadfan:
Hello again,

Yesterday I have received my H910 version of V20 - seemingly mint, made in Korea and with B&O headphones. Its hardware is fun and the brand of Android 7.0 is feature-rich but surprisingly buggy. The "old new" battery also does not last long at all + the device heats noticeably during regular usage (although this is my first phone with a metal back lid, so that could be the reason). I will definitely look for a grippy case, and even then not much hope for a single hand use...

I am not bothered by any of these but it's good that during the learning curve of flashing and using LineageOS my modest Lenovo A5 is still handling everything just fine with its well optimized Android 8.1, which I haven't even had to replace with a custom ROM over the years.

Some homework is due reading the threads you've kindly linked to. If all goes well and I get used to the device, I'd already consider getting another one as a backup - at this price I am fine with, say, lack of 5G in the otherwise decent phone. And meanwhile F-droid/Libretube are already doing wonders in my Lenovo A5 & Sharp Aquos C10, so many thanks for your recommendations - and best regards from Israel.
[LG V20 Questions & Answers] dextructor:
Yes, there's a couple of factors that you need to be aware:

1) The v20 and some other devices, didn't use any heatpipe/heatsink (but they should) so it's expected to generate more heat. You can make things better doing a "shin mod" (Don't peel the SoC cover like the guy on the video, the rest of the content it's good.

2) The SnapToaster 820 (aka. many Snapdragon SoC) had this thermal issues and the manufacturer can slightly tweak with the kernel if they want, but most don't. So using the Swan2000 Extreme, it's undervolted, generate less heat and have better battery.

Isn't rocket science, but it's doable. Just follow my recommendations, take time to do the whole process, take notes and everything will be fine.

I like the LibreTube concept and circumvention of most tracking by Google, but it has some costs like the unavailability of the servers from time to time.

The lack of some customizations and probably the framework library that's used it's a bit slower(heavier) than the Tubular/NewPipe.

I can use Tubular relatively well on my LG G4, but I can't say that my experience it's so good on LibreTube, but if works well for you, keep rocking!

Noob question for developers

I purchased the Sprint LG V20 (LS997) this past Black Friday and, like an idiot, allowed it to update to LS997ZV6 (February security update) before I rooted my device. I wrote to LG to find out if, even at EOL of device, would they ever release KDZ files for the Sprint and AT&T versions. They stated that they would not, however gave me a nifty website for their open-source code: http://opensource.lge.com/osList/list?m=Mc001&s=

My question to developers is this:

Is it possible, reading through the source code for the US996 (Carrier Unlocked version) and comparing the "FOTA" (\android\vendor\lge\fota) from source to unpacked KDZ file would it then give us necessary information on how to push a pre-rooted "OTA" to our devices or perhaps comparing the two files would give us the necessary information to create a KDZ file of our own for the Sprint and AT&T V20's?

I'm new to programming still and wondered if this was possible or if any developers that have been elbow-deep into the code if this even makes any sense before I delve into studying it for myself.

LGV20 vs995 Stuck in fastboot mode

Can someone help me? My VS995 is stuck in fast boot mode and my boot loader is locked, I screwed up during the wiping part of "me's" guide and wiped system and some other things. Whenever I issue a fast boot command it says "FAILED (remote: unknown command)" because the BL doesn't allow fast boot commands. Whenever I try to flash during download mode it installs and what not but then boots back into fast boot right after. Any help would be appreciated, have been trying to fix this non stop for the past two days, Thanks all.

No it is not. You need custom recovery to flash a rom. When it comes to flashing firmware - which maybe what you wanted to ask about - I don't think it would be a good idea so I would advise against it.

[LG V20 Questions & Answers] justFaisal:
I recently bought a used v20 and found it to be really slow for a 820 device. Phone is lagging all the time.

Did the benchmarks​ and got 98k in antutu. Was able to get 130k if i kept the phone cool by putting it front of a fan.

Is thermal throttling that bad on the v20? Open a couple of apps and it starts lagging. Phone doesn't even get hot to the point where you can feel it in the hands.
[LG V20 Questions & Answers] Creed14:
I'm looking for a new phone and I'm considering getting a used V20. Verizon is my carrier, can I use a US unlocked version, or do I need the Verizon one? Both are rootable and have unlockable bootloaders, right?

I like to run stable AOSP based ROMs, will I be able to do that on either the Verizon version or the unlocked one?

Thank you.
[LG V20 Questions & Answers] justFaisal:
Only T-Mobile has unlocked bootloader in the US. Not sure about the international. I'm using Verizon and it's slow as ****. LG has done some serious thermal throttling on their FW. Aosp should run smooth.
[LG V20 Questions & Answers] Creed14:
So even the carrier unlocked version doesn't have an unlocked bootloader?

Thanks!
[LG V20 Questions & Answers] justFaisal:
It looks like the us996 and h918 can be unlocked and you can install a custom FW on it.

Hope you have better luck with the v20. Mine was really laggy and then i noticed a dead/stuck pixel on the screen so i sent it to LG, hopefully they replace the LCD under warranty.

I really wanted to like the v20 but cant stand how slow it is.
[LG V20 Questions & Answers] OfficialVillager:
Serious thermal throttle isn't even the word. I intentionally try to over clock to test out performance and if the device gets any hotter than 35c, it will throttle the device down to 800mhz.
[LG V20 Questions & Answers] justFaisal:
I work in phone repair business and my theory for this is since LG made a **** show with their G4 bootlooping they're trying to keep the thermals down to decrease the risk of soldier getting messed up and having the same issue again. I have fixed a number of G4's just by reflowing the SOC.

I love the design and everything about the v20 but I can't stand how slow it is.
[LG V20 Questions & Answers] OfficialVillager:
Is that really what's happening? When my g4 crashed I just reflashed the firmware and was back to normal. But it was a common issue all the way up to the G5

How are ppl fastbooting vs995s?

I have tried adb, volume down/usb to get my vs995 to fastboot. I have tried 14b and 13a.

- adb reboot bootloader

and

- power off phone

- hold volume down 5 secs

- plug usb connected to PC with LG drivers installed

All it does is reboot

I can enter download mode and flash KDZs no problem. Does fastboot only work with 12??? I see roms for vs995 so it seems there is some way to get into fast boot. What am I doing wrong?
[LG V20 Questions & Answers] justFaisal:
You got lucky or you must've had a different issue and yes for data recovery purpose I've had luck with that process and I'm pretty sure that's why LG won't even let the v20 hand warm before they start throttling
[LG V20 Questions & Answers] OfficialVillager:
That's shocking because the only lg that I've owned that became untouchably hot was my v20 during all of my experimenting with ROMs. I work at T-Mobile so me seeing dead LGs is regular.

So I have searched the internet and found no good/complete answers for this, I apologize if it's been discussed.

I purchased an ATT V20 while I still had ATT. I've since switched T-MOBILE. My device is carrier unlocked but plenty of T-MOBILE features seem to look for certain software (i.e. mobile hotspot) that is ATT branded and nonfunctioning. Since o am operating fully on T-MOBILEs bands and what not, is there any way to flash my OS/kernel/etc to essentially make this phone T-Mobile branded. I am aware I will probably need to root if possible during the process, but im not looking for a relationship phone (right meow). Just a better functioning T-Mobile V20.

Thanks!

(Also I know all of this comes with risks, but I am out of the country and unable to get to a store should I brick it, so a good recovery option would be nice, but I think we are still stuck for ATT variant.)

My previous knowledge (from updating Galaxy note on att) says that sometimes Droid just doesnt like taking OTA updates. Keep trying but if you've gone through the process more than a dozen times already there's likely something wrong. As I haven't been on a stateside network long enough to pick up an OTA update for the V20 I can't tell you any more details. I would suggest trying to find a way to delete and redownload the update. But if it's 'verified' by hash then the download should be good. Hopefully someone much wiser than I has some advice for you.

Verizon LG V20 on AT&T

I got this phone from Verizon as a gift from someone, but I have AT&T. I programed the correct AT&T APN, and set the phone to GSM, but can't get this thing to stay on LTE for anything. When I scan for networks, I'll select AT&T LTE, it will switch to it for about 2 minutes, and go back to H. Any advice?

Also, what options do I have for flashing? Do I have to stay with Verizon variants, or can I flash an AT&T rom?

Partially Solved

Well, I wanted to drop a note on here for what it's worth. This phone wasn't kicking me off 4G LTE, AT&T was doing it. I have a grandfathered unlimited plan and I am at the end of my billing cycle at 8 GB of data used. Apparently, AT&T now doesn't throttle "excessive" bandwidth users, they must kick them off LTE until the end of the billing cycle. That's why it wasn't staying connected to LTE.

However, I still would like to know if I could run an AT&T varient rom on a Verizon V20 without too many reprocussions. Had anyone done it? Obviously the radio can't be touched, but other stuff could be baked in for better experience.

Thanks.

Anybody else have a problem getting into fastboot mode on the LS997?

If I turn my phone off and hold volume down + power I get into recovery mode.

Selecting reboot to bootloader from recovery mode just reboots the phone.

Volume up + power does nothing.

both volumes + power goes into IMEI Display with just the option to press power to reset the phone.

ADB reboot bootloader just reboots the phone.

ADB reboot recovery gives me the dead android screen, leaving that alone the phone reboots itself after a while. fidgeting with buttons causes it to reboot quicker.
