[LG V20 Questions & Answers] C D:
All I can tell you is with all my used V20s, before the KCAL fix, if I look at a mostly white screen on high brightness for just 15 seconds, I'll already see a shadow around the screen's edges the moment it displays something darker. After the fix, I have not seen any retention inside Android since. I only get it on the white factory reset screen, but that's outside the OS that you can't fix. This is one of those things you'll have to do yourself to believe it.
[LG V20 Questions & Answers] mickeyasamoah:
Thanks for the assurance. Really appreciated.

I wanna use the device for a while (2 or 3 days) to make sure there aren't any serious defects that would require me to return the device, then i will go ahead and root and apply this mode.

I read from the post u shared that the fix requires me to flash a kernel that has KCAL. Would i still be able to use FM radio with such kernels? I am really enjoying the FM radio and i wish to keep it :)
[LG V20 Questions & Answers] cnjax:
Checked your software version and I recommend using dirty santa to unlock the bootloader, if you decide to go with a stock based rom then go with the mk2000 kernel which has kcal support
[LG V20 Questions & Answers] mickeyasamoah:
Well noted! Does FM radio function with the mk2000 kernel?
[LG V20 Questions & Answers] cnjax:
I'm on stock based oreo rom for the H910 with mk2000 and Fm radio works with no issues.
[LG V20 Questions & Answers] mickeyasamoah:
So i was reading this thread about rooting the H910 with dirtysanta.

This part had me confused tho:

Since this method had been tested on 10m to 20g, and i have 10l which lower than 10m, do you think i should upgrade to 10m first before continuing the guide?

UPDATE: Scratch that, people have reported it working with 10L.

Also, i think i might quit asking questions which stray away from this thread so that others who had doubts about which V20 variant to buy wont have to read stuff that have nothing to do with that.

Thanks so much to everyone that helped to clarify things up.

I hope I don't run into any problems while rooting, but if i do, I will be sure to probably create a new thread or ask in the Noob Friendly thread.

Thanks once more
[LG V20 Questions & Answers] cnjax:
Personally since your on a security patch that's early I'd use the dirty santa method versus the other simply because that one requires you to flash the h915 firmware, which could cause connectivity issues, whereas dirty santa doesn't require you to flash a different variants rom
[LG V20 Questions & Answers] mickeyasamoah:
Could you please provide a link to the Dirty Santa thread?

There's also a second guide that has a few more screenshots to guide you along:

Definitely look at both guides to make sure you're following each step correctly.
[LG V20 Questions & Answers] mickeyasamoah:
Thanks, as i read through, i noticed that "AM&FM Radio no longer works".

Does this mean i wont be able to use FM Radio after rooting with this guide?

Yes Sir! I just noticed that my current ROM doesn't allow hotspot. For that reason, i was wondering which stock ROM or stock based ROM has KCAL and Hotspot functionality enabled?
[LG V20 Questions & Answers] C D:
For what it's worth, FM radio still worked for my two LS997s after rooting.

There was a tweak on the H910 for enabling hotspot at least on Nougat:

https://xdaforums.com/v20/how-to/to-root-v20-h910-tested-to-hotspot-t3838895

Perhaps cnjax can weigh in on that.
[LG V20 Questions & Answers] mickeyasamoah:
I am thinking of going with this thread as it supports linux.

Now once i am done with step 2, step 3 which is supposed to flash TWRP and quite possibly flash a boot kernel which used to be one that fixed screen issues and stuff.

Now i was wondering....Could i skip this step (Step 3) and probably flash the latest TWRP and also flash a stock based Oreo ROM with an updated SuperSU since the TWRP and Boot Kernel in the guide might be outdated.

Also, once i am done rooting with that method, would i be able to flash Oreo ROMs? Or would i be stuck with just Nougat ROMs.
[LG V20 Questions & Answers] princedede:
Dont skip any step. Just flash & follow thru...

And yes u will be able to flash an oreo rom.
[LG V20 Questions & Answers] mickeyasamoah:
Alright then. Are there any stock based Nougat and Oreo ROMs u would suggest i flash after rooting?
[LG V20 Questions & Answers] cnjax:
As I stated previously no problem with FM radio working, not sure about Hotspot as I never use it. Follow the guide, once you have the bootloader unlocked and twrp installed, from within twrp update to the latest version of twrp by flashing it using the IMG option. Perform a back up, then wipe system, davlik cache, format data, then flash your rom, I recommend Alpha Omega nougat or Oreo, immediately flash the mk2000 kernel, then flash supersu or magisk before your first boot to system.
[LG V20 Questions & Answers] mickeyasamoah:
Hmmm....So i used this thread. I was able to flash TWRP. Now i keep getting static boot when trying to boot into the stock ROM.

I was able to fully boot to android after flashing the bootbackup.img. But now, it wont boot to android anymore. It's just stuck on the static boot.

I am trying to boot into recovery but that's not working either. I was able to boot into TWRP previously tho. Anyway while i was in TWRP i wasn't able to access my Internal SD, had to slot in an SDCard to flash v1.5 of mk2000 and that didn't boot either.

Don't know what's going on now

UPDATE: I booted to fastboot and typed "fastboot boot bootbackup.img"

Although there was static boot, it booted into android once more.

Is there a version of mk2000 that works with my software version?
[LG V20 Questions & Answers] mickeyasamoah:
UPDATE 2: I am able to boot into android with my stock which was renamed to bootback.img during bootloader unlock.

I still get static screen during boot and i have to cover the proximity sensor while locking the screen to get rid of the static screen for that boot session.

I am also unable to root the device. I am pretty sure it's because i am booting the stock boot. Back on the G3, the stock boot prevented root. Hence the devs had to make a custom boot which would keep root intact.

Currently, I am experiencing problems with broadband and as a result, i wont be able to download a ROM(a whooping 2.*GB) as i am using mobile data. Hence i was wondering if i could find an MK2000 boot which supports the H91010L ROM I am on at the moment. That way i would be able to root, set KCAL values and enjoy the battery life this ROM provoides. (I got 24+ hours with light usage on a single charge).

UPDATE 3: I just found a boot/kernel called BTTF from this thread. It claims to support KCAL i hope it fixes the static boot and keeps root.
[LG V20 Questions & Answers] cnjax:
That's the mk2000 kernel for Nougat, flash it, that should get rid of static on boot, if you are having a problem with rooting with either supersu or magisk it could be the twrp version you're on. If you choose to use use supersu, go with supersu 2.82 sr5 it's the last version built by Chainfire, after flashing the kernel you should immediately flash either magisk or supersu before booting to the os otherwise your device will re-encrypt
[LG V20 Questions & Answers] mickeyasamoah:
Do i have to factory reset too?

I am stuck on secure first boot or something like that.

My old knock code wont work, So i have wiped cache, data and dalvik yet i can't seem to get pass the secure first boot.

UPDATE: So i wiped the entire data partition and with that, i was able to boot into android. Surprisingly, there was no SuperSU app nor does typing su in terminal emulator work.

I am pretty sure that the device didn't re-encrypt as i am able to access the internal storage from TWRP.

I am reflashing SuperSU again. Will report back.
[LG V20 Questions & Answers] mickeyasamoah:
It's working now. TWRP is working, Kernel seems to be working with no static screen, SuperSU app is displaying.

I seem to be getting a force close on every boot tho.
[LG V20 Questions & Answers] mickeyasamoah:
Everything seems to be working fine. No more image retention.

Yet, i noticed battery life is not as it used to be. Same applies to snappiness of the device. It used to be much snappier.

I guess i am gonna hold on to it for now until i can download the stock but fully rooted Oreo ROM.

I'd like to thank all you guys that helped right from guiding me through acquiring the next big variant of the V20 down to unlocking it's bootloader, rooting and flashing MK2000.

I hope this thread helps others in the future just as it helped me.

I might bother you guys should i face any challenges tho:p
[LG V20 Questions & Answers] cnjax:
That force close is an old bug, dev meant to remove the app, you can just delete app to get rid of the force close on boot. You need to let the kernel settle for a bit before judging battery and other stuff. You should find better battery less heat, etc compared to the stock kernal. Look up AKT I use it with the mk2000 kernel and get great battery life
[LG V20 Questions & Answers] mickeyasamoah:
Oh...Ohkay. I will remove the app then. I just got an "Unfortunately, android has stopped." Not sure how to go about that tho.

I will checkout AKT right away.
[LG V20 Questions & Answers] C D:
If I remember correctly, there is an apk version of AKT 1.6 hidden somewhere in one of those AKT threads from the OnePlus3 section. That'll make installation easier if you can find it.

Another similar alternative is the Magisk module LKT. I have used both AKT and LKT and found no noticeable difference in battery life between them, but that may vary based on your usage.

Also, if you are currently using an LG OEM battery, then you might want to consider looking at getting one of those 4100/4200 mAh Lithium Polymer batteries made by various brands such as Perfine, MaxxxJuice, Shenmz, and Taeozi. They are the same size as the OEM battery but actually have a higher capacity. Some of them have been mentioned in this battery search thread.
[LG V20 Questions & Answers] princedede:
Okay. Glad u av been able to root. So after u download android Alpha 8.0 rom. I believe u will have a smooth sail. But for a safe installation:

1. Get the latest TWRP and flash the recovery from Twrp.

2. Format data. System, data, cache. Or go through Alpha rom 8.0 thread and follow the steps. U will be fine after flashing. Everything works here with me. I'm also on MTN Nigeria.... Battery life too is okay. Though i have ordered one of those 4100 mah battery.
[LG V20 Questions & Answers] MEMO#22:
Yeah H910PR is a pain, it's my current phone that i bought online with a Claro firmware

You can still unlock , root , and install custom roms on this device with H910, H915, US996 methiods, one major issue that i'm facing is just i can't install any custom kernels.

i dunno maybe there's just something wrong with how i root my device, i haven't looked much further into it because i fear i might break my device, H910 method worked tho
[LG V20 Questions & Answers] mickeyasamoah:
I will check it out once the broadband is up and running.
[LG V20 Questions & Answers] mickeyasamoah:
By " i can't install any custom kernels" do you mean when u flash a custom kernel, the device doesn't boot? doesn't boot?
[LG V20 Questions & Answers] mickeyasamoah:
Guys, So i thought this was normal but i guess it isn't.

After i used dirty santa to unlock my phone, i noticed a warning message at boot. Now i had read that there was going to be a warning message from the aboot at boot so i thought it was normal until i saw how that warning actually looks like from this Thread.

Like so:

But this is how mine diplay's that warning:

Is it normal or did i do something wrong.
[LG V20 Questions & Answers] C D:
Definitely not normal. Maybe some files were corrupted during the whole process.

Curiously enough, someone else reported the same problem here:

https://xdaforums.com/v20/how-to/lg-v20-stuck-how-to-repair-h910-t3955662

Does yours continue to boot or get stuck?
[LG V20 Questions & Answers] mickeyasamoah:
Hmmm...Mine boots alright. Apart from some app/process crashes and also the device deciding to go crazy on me last time when it was on 5% battery and when i connect the charger, it will constantly connect and disconnect and the screen's back light would go from high to dim over and over until i turned the device off and charged, i think it's okay
[LG V20 Questions & Answers] MEMO#22:
After installing a custom kernel, the device just goes to fastboot. It won't proceed to booting

But i can still access TWRP so i can restore my backup before i installed the kernel, then it boots normally now
[LG V20 Questions & Answers] mickeyasamoah:
Hmmmm....Weird. What ROM do you have installed?
[LG V20 Questions & Answers] MEMO#22:
After i rooted? I installed a stock Oreo rom that was provided from a rooting thread (rooted 20h)

I did a little backread and regarding on the warning sign being static i thought that was normal, maybe there is something wrong with how i root

But i followed the instructions carefully for like, three times already but same results.

So it's tiring to go back and do it all over again
[LG V20 Questions & Answers] mickeyasamoah:
Guys, I think there's something wrong.

After unlocking the bootloader, shouldn't the lock state in bootloader change from locked to unlock or something?

Cause mine still shows up as locked.

UPDATE: Could some one enter the commands I entered "fastboot oem device-info" without the quotes while in fastboot and send a screenshot?
[LG V20 Questions & Answers] ezzony:
Can't be troubled to do a screenshot but I just did this for you on my rooted bootloader unlocked device and everything showed up false just likes yours. On the fastboot screen on your device there is a red label on the top of the screen, I think that indicates security is off. You won't see this red otherwise.
[LG V20 Questions & Answers] mickeyasamoah:
Cool. One thing that bugs me is that, mine doesn't show a readable text with a single triangle at the top, instead, it's shows a scrambled text with about 4 or more triangles. I posted a screenshot a few pages back. I was told the scrambled text started after the Oreo update. But here's the case my device is on Nougat. It has been on Nougat since I received it.
[LG V20 Questions & Answers] crumbling9999:
Unless its a US996, no V20 can be bootloader unlocked. The DirtySanta method simply flashes the leaked Engineering Bootloader, which doesn't check for signature at all. Its like changing the lock so it opens to any key vs removing the lock altogether.

As for the scrambled text, its because of the engineering bootloader. Flash a custom kernel and it'll sort itself out. Alternatively, put your hand over the light sensor, then turn off the screen. Keep it there and turn it back on, it'll fix itself until the next restart
[LG V20 Questions & Answers] cnjax:
It's not caused by static, covering the proximity sensor gets rid of the static on screen, but does nothing for the scrambled bootloader screen.
[LG V20 Questions & Answers] crumbling9999:
The scrambled bootloader is caused by the same reason as the boot static. The engineering aboot was taken from a prototype device, and there was some changes between then and release. You can adjust the value in the kernel to compensate, but you can't fix it in laf and aboot. I've had it happened once flashing a H910 package onto a LS997 to see if the radio works, its just a general kernel/aboot incompatibility issue as far as I know. Flashing a US996 based KDZ (minus aboot and maybe modem) should fix the issue.

Or even just raw_resources
[LG V20 Questions & Answers] princedede:
U can easily use dirty santa on it without Flashing the H915 kdz. Just use dirty santa. Then upgrade your TWRP to the latest..

format data,

Wipe system/data/cache/dalvik/internal storage

Install los 17.1 official

Flash magisk 20.4

Flash nano gapps

Really, it's OK. People have weekends on the internet too.

Rudegar was correct in what he said to you. Maybe he assumed that you were a bit more savvy when it came to this kind of stuff. What he means is that through the File Explorer or another similar program like Resco or Total Commander, navigate over to the "\windows\start menu\programs" folder on your device. Once there, delete the invalid shortcuts. This will resolve your issue.

[LG G6 Guides, News, & Discussion] dwasifar:
Recently my G6, purchased in September 2017, developed a hardware problem in the power button/fingerprint reader. It's in the second year of warranty through LG Promise. I still like the G6, and since they're now bargain priced at B&H, I decided to buy a new one before returning the old one, planning to warranty the old one and keep it as a spare.

Getting warranty service on the old one was fairly straightforward with a couple of small quirks. Regular LG support doesn't handle it. Instead they transferred me to another number where the person just answered Hello, but she was pretty efficient about taking my information and promised me I would be contacted by email with instructions. Those showed up a day or two later, and after providing them with photos of the defective phone (to prove it wasn't physically damaged) they sent me a prepaid mailing label and shipping instructions, with the promise that once the tracking showed the package en route, they'd send out a replacement. Which they did.

While waiting for that, I went to register my new phone with LG Promise, and that didn't go nearly as well. First I discovered that they're cutting off registrations as of purchase date 06/15/2019. It doesn't say anything on the website about that. Fortunately I had two receipts for the purchase (long story there), and the earlier one was dated just before that. But then the website told me the IMEI was not valid. I contacted them by email for help, and they said they didn't have the phone in their system and I should wait a few days for them to validate it. It's been five days and I'm still waiting for that.

In the meantime, the replacement phone arrived. They sent me a new-in-box unlocked G7. That's actually very nice of them, since it's an upgrade, but I can't root it (no bootloader unlock available from LG) so I really can't use it and am selling it. My wife and I always have the same phone, and I want to stay with the G6 a while longer rather than buy new phones for both of us.

So the experience with LG Promise, and LG phones in general, has been a mixed bag. They seem to have some serious internal communication problems. I had the same IMEI issue when I went to get a bootloader unlock for the new phone, and it took them a week to resolve that. (Regular LG support was no help in that regard; their people are completely unaware that the developer program even exists and told me that LG never provides bootloader unlock and developer.lge.com is a hacker site.) I like the phone itself but I'm not crazy about the support and will probably switch brands next time around.

If you think about it, it's not really surprising old ROMs would start having problems. Amazon can reasonably expect that any of their devices would be updated when used, so after a while they wouldn't even bother testing against something as old as 5.0.5

So I wouldn't say they are blocking root users, instead root users are choosing to use the devices differently, and as it says in every ROM thread "at your own risk"
