I have. Whenever someone helps me, and I got a lot of help on internet forums, thanks to the good people of this world, genuine gratitude is important for me. However, just because I am in a needy situation does IMHO not oblige me to be submissive in face of cockiness and smugness. Then I do speak up. And sometimes relationships on the internet are simply in a dead end street, and then a temporary ignore is the only way out. And how "smart" someone is, is neither something anyone can do anything about, nor is smartness particularly important in this field here; the main distinction here is how much EXPERIENCE you have with unlocking&rooting phones. And my experience is admittedly very limited, I only have two experiences in the super easy Samsung S4 and S5 world, where unlocking&rooting&installing-LOS is a matter of following one rather simple, and very complete manual. Probably it is much furthered simply because there are 97 times more downloads for klte than for h910. Compared to Samsung, the LG world seems about a dozen times more difficult, has many many more trapdoors, and seemingly you have to read 7 OPs plus the 7 whole threads first before you even begin. And memorise everything, of course, lol.

You really don't have to give me credit. I just want to help to prevent, that others fall into the same traps that I fell into, following your guides.

Please add

--> that "C:\Program Files (x86)\LG Electronics\LGUP" folder, plus

--> these "Suggestions to be added to dksoni411's manual".

In hindsight, I could have communicated about YOUR manual here in YOUR thread instead of over there, yes. And I did actually post here too. However, I got ANSWERS over there, while your thread was silent. That made me communicate over there. Perhaps that explains my evil behaviour of talking in the "wrong" thread?

Also I had been pointed to your manual over there in THAT thread, it was recommended because it is new, and it needs only one CLI command. And then I did not read all the other dozen threads because I had assumed reading yours was enough.

I like the JustRunMe.cmd tool that you built, thank you very much for it. Much appreciated. I suggest you put a few more hints into your manual, and perhaps then you can in the future prevent similar cases like mine.

Thanks!

Yes, and the worst feeling is when you have already put > 20 hours into it, and it's only getting worse, and you think: S**t, more rational it would be to just give up. But I really dislike throwing away new hardware. And then the next day, the memory of suffering has faded, and perhaps someone encourages you to keep trying ...

Thank you so much. That is much appreciated.

Success: My h910 (which had been turned into a h910PR for a few days) is a H91510e now, hooray. Thanks a lot to all benevolent supernatural and to all helpful earthly beings. What a relief.
[LG V20 Guides, News, & Discussion] ankade:
Plus one more thing to possibly add for h910 users:

We can swap your (old and for 996) TWRP.img in your "LG V20 Root Package (1).zip" for this one: https://dl.twrp.me/h910/ because it is newer, and for the h910; replace by renaming twrp-3.2.3-0-h910.img to TWRP.img, before step3.

My Experience

First of all, thanks for the work made here, i aint no noob on this, but still, this was a heck of an easy to follow guide and procedure, you have to be very dumb or not pay any attention to mess this up.

So, i was, i dont remember the version, but it was the September 2016 update on my h910, i followed the tutorial and everything went fine, but i was getting kind of a bootloop, the phone was starting but with the sim on it would reboot after selecting the wifi, and without the sim i could finish the setup but it would reboot in less than a minute, during one of the reboots, it took me to a screen similar to the fastboot or bootloader screen and it pointed out that the kernel had a problem, so i went ahead and downloaded the rooted stock oreo rom with the suggested kernel plus the oreo twrp, installed everything and now i have zero problems, everything runs smooth and i have the same battery life than before.

So, thanks again! (i already hit the thanks button ;)

How does the dac and second screen working, same as stock?
[LG V20 Guides, News, & Discussion] Jc_master:
Well, the rom is stock but rooted 8.0, so everything works as expected.

Sorry if this sounds dumb as this is my first LG Phone, But if i flash the h915 on my h910 will i still be able to use my Data
[LG V20 Guides, News, & Discussion] Vortell:
If not pretty sure you can use kdz writer built into twrp to write a modem back into it. Make sure to back everything up first. Search for you model in the different guides there is tons of info about the h910 out there. Including in this thread Just use the search function in each thread. Maybe someone with the h910 can chime in on weather it all worked. From what I gather from the stopping of comments I think it did. I think you can use a us996 Kdz as well.
[LG V20 Guides, News, & Discussion] Navalier:
Thanks for telling me, I will check very quickly and if so then i'll do this
[LG V20 Guides, News, & Discussion] Vortell:
Seriously backup the phone phone first! There is no kdz for h910!

Hello there, first post of the year for this thread, hoping to get a first reply also :D

I just got an LG V20 US996 (UCL version), right now it is updated to US99610p version. I am about to proceed with DS root.

Could anyone (especially one who has rooted same device via this method) confirm the steps i'm about to take;

1. Downgrade to US99610g using patched LGUP (and Uppercut)

2. Proceed with OP's guide to unlock bootloader and install TWRP

Thanks in anticipation
[LG V20 Guides, News, & Discussion] cnjax:
I suggest you do some more researching as I believe I read someone else had issues rooting and flashing roms on the ucl variant
[LG V20 Guides, News, & Discussion] Vortell:
It's the same process as bright point like I have and it works fine. If you have questions just about any if them are answered either here or the rooting guide in rom section. Honestly can just search for my in username. Since I went through the be process I have tried to help. Honestly everything you could need should be here on it around my comments.
[LG V20 Guides, News, & Discussion] fralyx:
I have the VS995, downgraded to Nougat 12A (before the DS exploit patch), and followed the steps.

Now it doesn't seem to finish the boot process at all & I'm stuck at the loading screen. Flashed the boot2 image and still no success.

Edit 2: I've managed to boot into TWRP and flashed Magisk, but even then I'm still stuck.
[LG V20 Guides, News, & Discussion] Vortell:
Update twrp then download and install a new rom. If you have twrp you have the hard part done...
[LG V20 Guides, News, & Discussion] fralyx:
How do I install new ROM? Is it possible to install KDZ roms from TWRP? And won't it remove the ds exploit if I just flash the latest one?
[LG V20 Guides, News, & Discussion] bhizzle:
Thanks for the reply.

Getting confused because most people who confirmed rooting their us996 sucessfully didn't say if it was the carrier unlocked version or the UCL version.

So if i decide to proceed, can i begin the DS process on the US99610p patch without issues? Or do i need to downgrade first

[LG V20 Guides, News, & Discussion] cnjax:
You need to downgrade to a security patch prior to Dec 2016
[LG V20 Guides, News, & Discussion] cnjax:
Why should someone do your work, go search LG's website for firmware and read the instructions in this thread
[LG V20 Guides, News, & Discussion] mreps07:
ive been in the forum quite sometime but it's my first time to encounter a "senior member" with attitude as you..i was politely asking for guidance and i really never expected to get such reply from a senior member like you
[LG V20 Guides, News, & Discussion] cnjax:
First you did not ask for guidance, you wanted someone to go search for links, and if you've been on the forums for a long time then you'd know you're suppose to search research and read yourself
[LG V20 Guides, News, & Discussion] mreps07:
Do i need to downgrade my v20 to a firmware with security patch prior to dec 2016?

isn't that phrase asking a guidance followed by a request if possible?

if then so, can u please assist me in getting the necessary files and tutorial link please,it will be a great help for me.

now if you have no intention helping, please just seat and don't react as if you're a contributor or something in this thread

never i'll sticked to the other thread where the OP is gladly helping with no questions asked.

sometimes some members gets head bigger when ranks as "senior member"

[LG V20 Guides, News, & Discussion] Vortell:
Yes though it needs to be in a firmware package before dec 2016. On my us996 you look for firmware before 10p which is the last 3 in the firmware number. I thought the number scheme was the same for all v20s. Lg-firmware is the site I think most people go. If you search for your model it should last the options. There are other places but they are kind of buried compared to that site.

---------- Post added at 06:29 PM ---------- Previous post was at 05:47 PM ----------

Technically it's p possible with newest twrp with kdz writer built in. There instructions are in twrp thread in rom section. Honestly why I suggested you update twrp right away. (At least I think it was you) I won't though. I be would just try to install a different rom from over there. Maybe alpha Omega if you want stock. Be warned though if you go to Oreo only way to use non-stock ROMs and have everything with right it's too do full kdz restore and reboot it. So use alpha Omega nougat if you want to use lineage based ROMs.
[LG V20 Guides, News, & Discussion] fralyx:
To be honest with you, I still want to keep the second screen, because I use it most of the time :laugh:, usually for screen capturing or just a quick launch of my frequently used apps. I want a custom ROM only if any of them can support the second screen, otherwise I might be forcing myself to stick with stock Nougat.

P.S: Re-flashed the stock Nougat via LGUP and it came back to life :D
[LG V20 Guides, News, & Discussion] Redline:
As much as I do agree with the fact that people need to search for things us more advanced users consider common knowledge, especially since there's dedicated threads for this information, as well as the fact your post directly above [MENTION=4688274]mreps07[/MENTION] 's states exactly what he has to do, this IS tagged as a 'Noob friendly' thread.

The spirit of XDA Is also helping others around us with the sometimes more involved processes needed to do certain things.

He also asked for help obtaining the necessary stuff to go through this process.

There's better ways to go about pointing someone in the direction they need to go to get to something, without completely letting them have you do the work for them.

Such an example is telling someone what specific thread to search for in its relevant sub-forum. "If you poke around the ROMs subforum you'll find some custom kernels if you don't like the stock one" or "The ROMs subforum has all our custom ROMs if you want to try something other than stock".

This doesn't require you to do any work yourself, other than replacing your multiple off-topic and unhelpful posts with ones that actually

DO

help people.

I've no doubt you yourself know what information he's after, and could instead help a new member out in a new member friendly thread rather than turning them off the already painful process needed to get a better-than-stock experience out of the device we all love.

Also, for all anyone knows, he's on a mobile-only account, which DO exist for members that don't have desktop-access, and as such would be less aware of the processes involved with/related to search as a function.

This is why it's always better to help someone out.

The member DID in fact ask for guidance, and he is also not as long a member as yourself, hence his lack of a Senior Member tag.

Now [MENTION=4688274]mreps07[/MENTION] we've got some good people here in this forum, so don't be afraid to ask for help :)

As [MENTION=1795879]Vortell[/MENTION] has already said, yes you'll need to downgrade to a KDZ with a patch date prior to December 2016. For the H990 (for example) this was v10c.

Vortell is also correct in that you want a pre-10p version if applicable (anti-rollback protection was implemented in 10p, you can't go back once you go past it). The rest of the things you need can be found in his post just above (in reply to you) or in the OP of the thread. I don't know which exact KDZ version you need for your variant, but you should just be able to flash the earliest available via LGUP.
[LG V20 Guides, News, & Discussion] Redline:
There are second-screen enabled versions of ResurrectionRemix (LineageOS 15.1-based but is more up-to-date than the about to be mentioned) or LineageOS 15.1, however LineageOS's second-screen version is a few months out of date now.

There is also LineageOS 16.0 which, while in beta and only on its second public build, does natively support the second screen by way of Android Pie's notch support, natively, without any modification required.

If you choose to go with a LineageOS 15.1-based second-screen ROM, there's a second-screen version of Gamma kernel that I maintain if you need anything other than the stock kernel (for more governors, KCAL support, etc.)

You will have a much, MUCH improved experience on a custom ROM than anyone ever will on stock. The V20 becomes a whole different device.

I have a review/guide coming in the next day or two which I'll be posting detailing battery tips and how I achieve 5-6hrs SOT on LineageOS 15.1 with the stock LG battery, and up to 10 hours on a new battery that has a bigger capacity and fits into the same physical size.

In any case, having had it as my daily driver for more months than I can remember now, LineageOS 15.1 will serve you well, provided your TWRP is up-to-date.
[LG V20 Guides, News, & Discussion] cnjax:
I disagree, if members would read the threads then they would have found the answer without having to make a post please give me this or point to that. As you stated there's numerous threads with the info needed if the members weren't lazy and took some time to read, and searching on the xda app on a mobile device is not difficult I do it all the time, and it's simple to do a Google search through your web browser
[LG V20 Guides, News, & Discussion] fralyx:
Ah I see .. thank you :) I will try Lineage then.

Even though there's clear steps, usually it is not that easy to the newbies. I mean what's wrong with asking? That is the purpose of a "forum" anyway ... (One way to spawn two mods eh :laugh::laugh::laugh: )
[LG V20 Guides, News, & Discussion] Redline:
I'm inclined to agree, but I remember how it felt being brand new to the V20. I trawled over every single page of the DirtySanta root for H990 thread before going ahead.

But that thread is approaching 200 pages long now, a year ago it wasn't anywhere near that. I don't blame people for being intimidated and getting lost in the sea of information, advice and experience in that thread alone.

Then there's all the other threads the V20 has for everything. It can easily be overwhelming. You could easily spend weeks reading everything on the V20.

I disagree with saying "Cya/goodbye" to someone and telling them to go dig for treasure somewhere else on the beach, as it were.

Sharing is caring, and XDA is built on that.
[LG V20 Guides, News, & Discussion] Neo:
Your attitude throughout this issue (which wasn't an issue until you made it one) is very poor. While we want members to do a little self help by searching, there is no reason to react in a hostile manner. If you had any intentions to help, you would've stated that they need to search first, and then offer some assistance by at least pointing him in the right direction. That is the spirit and ethos of XDA. However, it is clearly evident that you had no intentions of helping this member, In which case, you shouldn't have bothered responding.

From here on out, I want to see some decency between member interactions in this thread, from everyone.

Can someone tell me how to cross flash with LGUP on the h910
[LG V20 Guides, News, & Discussion] Redline:
Post #2 has a link to the patched LGUP you need.

The OP states

So proceed at your own risk, but simply flash a H915/US995KDZ as you would any others. Flashing a version of something for one variant on another is inherently what cross flashing is.

Thanks [MENTION=1795879]Vortell[/MENTION] and [MENTION=591810]cynjax[/MENTION] for your helpful replies. I'm about to start the process now, feel a bit nervous as i don't want to brick this device in anyway, can't afford to lose a phone or get another one now.

One quick question before i proceed; can i do a dump of my stock rom (all partitions) using the regular LG UP tool (without Uppercut)? I need to have something to go back to just in case of anything.

And do i really need to use the patched LG UP or Uppercut (with the DLLs and stuff) 'cos i cannot really tell the difference with that and a regular LGUP

I apologize for the noobish questions.
[LG V20 Guides, News, & Discussion] Redline:
You do need to use the patched one yes, at least I did a year ago when I did it.

You may not be able to tell the difference on top, but it's how it works underneath that matters.

Not sure about doing a dump, but as long as you have a KDZ to revert to, it completely wipes your device and starts from scratch, so that'll work for you.
[LG V20 Guides, News, & Discussion] bhizzle:
Thanks for the swift response. I will proceed with the patched one then. Already extracted it to the directory as instructed in OP's 2nd post.

Do i need to use Uppercut along with it? Please
[LG V20 Guides, News, & Discussion] cnjax:
Yes use uppercut
[LG V20 Guides, News, & Discussion] dksoni411:
Uppercut is not required if you use patched lgup.

If you use normal lgup then you need uppercut.

Don't use refurbish option when using lgup with upper. Use upgrade option (second radio button) to flash any kdz.

Also patched lgup can dump all partitions (if you ever need them).

Didn't realize patched lgup could do that thanks for the info!

I use the latest one from the Magisk thread, think it's v18. Install the Magisk Manager, reboot to TWRP, flash Magisk and then reboot again.

Should be good to go. Make sure your TWRP is up to date by flashing the version from Phoenix591 too.
[LG V20 Guides, News, & Discussion] bhizzle:
Flashed magisk and the latest TWRP from Phoenix591, root process done and dusted!

I installed RR ( the second screen version) and gamma ss as well, ROM looks good (been a fan of RR from my G2 days). I feel the need to update my phone's modem cos the rom looks a bit glitchy for me (whenever i dial a call it takes about 10secs before it shows the dialling screen, dark mode does not enable, etc)

I'll have to do a dirty flash again, but can i go ahead and update my modem to at least a most recent without risking losing root access?
[LG V20 Guides, News, & Discussion] Redline:
Yeah. Use KDZ Writer to update the modem to one from the latest KDZ for your variant BEFORE v20a.

[MENTION=6984210]emdroidle[/MENTION] said elsewhere using v20a modems on AOSP currently causes kernel crashes, so for the time being use one of those v1x ones (should just be able to use the latest stock non-Oreo KDZ like I said above).

I don't know if updating your modem will fix that though, dark mode not enabling wouldn't be a modem thing, not sure about the delay before showing the dialer.

I actually haven't updated my modem since I went to LineageOS. Wonder if I should? Or more appropriately, wonder if I NEED to...

Edit: Last KDZ I flashed on stock before going to LOS was v10g-AUS but this is also the latest version before v20a, which as we know, using the modem from causes issues.
