Hello,
First off, thank you for clicking on this post. I'm new on XDA and rooting LG phones. However, I've searched help on posts and other sites on how to root LG V20 H19810k (T-Mobile Variant) and many told me to downgrade first and then root. But none exactly gave any instruction or step by step on how to do it.
My worries are these ARB (Anti-Roll Back) software updates and if you were to downgrade, you will brick your phones and things like that, it's LG (I mean like there are a lot of complains about hardware faulty after phone updates and lawsuits about it), and different steps on each variants. I bought this phone like 2 or 3 months ago, and my thought on this phone's software is sucks so bad. It's so bad, I've had many problems like my mobile data often times stopped working (no network) even though signal is full bar, my live pixel background suddenly gone after playing this specific game, serious low fps in some games, RAM is full all the time, and many more. The phone itself has amazing hardware and specs, but damn why is the software so bad?
Right, so all my problems aside, I think switching ROM or downgrade probably a good idea and rooting for removing bloatwares. But many had problems installing twrp recovery to root and risks like bricking and bootlooping. And in this post, I'm hoping for help to downgrade and root H91810k.

Search this forum there's numerous threads on how to root
Sent from my LG-H910 using XDA Labs
Downgrade to 10j and use DirtySanta, or use lafsploit.
IMHO they are about equally difficult. In the lafsploit thread, I state that you have to be on 10p or 10q, but I will update the post stating that you need to be on 10q or LOWER.
DirtySanta doesn't require you to use FWUL, so it does have that advantage.
Bottom line though, you can't stay on ARB 0 firmware and use any of the current ROMs -- they all require 10p or higher firmware.

Thank you for the reply,
Seems I got it a little bit. So what I've been looking at this dirtythis and that unlock stuff for quite a while. I've been wondering if anyone asked about H918. I just realized that this dirtysanta bootloader is an exploit for other variants that don't support unlocking via fastboot.
So then I proceed to unlock my device and it successfully unlocked. (Follow this post to unlock).
I will try downgrading my device via lgup and will follow this post to flash and root.

Be careful about your rolling back to root, check your current software version and and if you're arb 1 you'll brick. If you're arb look up the laf exploit thread
Sent from my LG-H910 using XDA Labs
He said he is on 10k, so he is safe to rollback to 10j which can use recowvery.
@ignoll Whatever you do, DO NOT flash the engineering aboot, or you will brick your phone. Follow the procedure in the post you linked, and you will be fine. DirtyCow gets you a temp root shell that will allow you to dd TWRP onto the recovery partition. If you get an error when you do run-as con, then you are NOT on 10j or lower. If you try to downgrade and you get an error about ARB, then you are NOT on 10k.
Just keep all that in mind and you will be fine.

Thank you for the reply,
Just to make sure, 10k is the software version which you can find in the software info inside the settings app, right? This software info will show stuff about "Android version", and down on the list, there's the "Software version" and below it is the 10k coming from (H918xxx). Or, check it via svc menu and version info through the dialer app. All that is to check whether I'm in the correct version or not, yes? (Sorry for this silly question, I just want to make sure. I'm really new to this)
And yes, I won't flash this engineering aboot, just follow the instruction and I'll be good. But just to make sure again, there's no this "engineering aboot" thing in the post that will brick my device, yes?
That said, I really appreciate for your warning and advice.

Please, i am also stuck and confused, as i understand LG devices, downgrading may cause device to go dead completely, i want to be sure before i begin this process. Here is my device Software Info:
Software Version: H91810K

My device is locked to T-mobile, and i want to unlock using Octopus Box as i have credits. Unlocking requires root, is it possible to downgrade to the mentioned version 10j and not brick device? Any one can help me on this.

That is only true if the engineering bootloader is used. The H918 still needs work to get it carrier unlocked.

Did u unlock bootloader using this method?
mingkee said:
You can do this:
Make sure you backup your data with LG Backup to memory card.
Enable Developer Options (hit build numbers in about phone few times).
Enable OEM Unlock and USB Debugging.
When hooking up with your host computer, check the phone screen to allow your host computer.
Open cmd
Locate your adb platform-tools folder
adb devices
adb reboot bootloader
fastboot oem unlock (doing such will erase your phone)
fastboot getvar unlock
fastboot boot TWRP.img (if you have compatible TWRP)

I guess he's just priming the pump for the inevitable hundreds of threads asking if the bootloader is unlocked or the "HELP!!! I'VE BRICKED MY PHONE AND I CAN'T GET UP!!!" threads from the morons for whom reading is not fundamental.
Since the bootloader is unlocked, is it safe to assume at some point we will have root?
Are you able to use fastboot commands? Such as to write a new recovery img. After that getting root is usually a piece of cake.
Not sure if it's different in Nougat but I think with an unlocked bootloader it really is just a matter of time till we get what we want (root).
As a piece of reference on the T-Mobile G5 we were able to root the G5 only after getting a .TOT with TWRP as the recovery because T-Mobile had somehow removed all the fastboot commands on that device except fastboot OEM unlock. If that is the case with the V20 we need talk to @tungkick again to manufacture another .TOT for us again.

Yes I think so from my previous experience this is almost always the case.
With the V10 a user @tungkick created a .tot with root (SuperSU) patched into it. Then use LGUP to flash the .tot.
Once that is done flashing TWRP can be flashed using Flashfire by Chainfire.
Or instead of patching root maybe the .tot can be modified to have TWRP built in...?
Nvm...didnt read the previous comments.
Well. Someone in androiding.how is keeping track seems like it. According to what i read, quoting
"The root method for LG V20 will be a systemless root without doubt. Android Nougat comes with enhanced enforcing SELinux policy for better security on Android devices, so systemless root will be the way to go to get root access without compromising the device’s security."
So, if this is true, at least there is a path to follow.

Systemless root is almost becoming the default now. And if we have TWRP is pretty much just flashing the systemless root and that's it. In the recent past systemless root has not been a problem.

Is there any root yet for H918 10p if so... Please direct me to it asap lol. If not I might have to warranty exchange and then root or wait.. Thanks guys!
10p currently can not be rooted. There are some thoughts and ideas floating around, but more than likely another Linux kernel exploit will need to be found. Also, just an FYI, T-Mobile incremented the ARB version for 10p, so don't try to force an older version to flash -- that will blow the qfuse, and that is a hardware issue that can't be fixed without replacing the CPU.

My first Android phone was an HTC EVO 4G (the original WiMAX version). The first one that I got had an HBOOT with S-ON (locked bootloader). Reading on here, I found out that there were versions with an older HBOOT that had S-OFF, so I carted my butt down to the Sprint store and didn't even make up a story. I told them flat out what I wanted, and since I was still within the window of being able to cancel my contract, they took me back and let me look at the boxes that they had. I found one with the proper version, opened it up, verified that it was truly S-OFF and that was it.
Now, that was back in 2012 and things have changed since then. But if you just bought the phone, take it back and tell them exactly what you want. The LG V20 box has the software version that is installed on the UPC sticker.

Brian,
I'm not sure what version of the V20 you have, but I've got the H918 and I'm running 10p rooted with Magisk. I started with SuperSU, but wanted to start over and try out a systemless root. Real simple steps too..
1. Unlock bootloader
2. Flash SuperSU or Magisk
3. Root achieved.
I attached a couple of screenshots. How easy LG phones are to unlock the bootloader and flash root is the reason why I always buy LG phones, not Samsung.
Cheers!

Don't know where you get your information from, but a qfuse will never be triggered with oem unlock on. and all it is is a warranty bit. just states that your warranty is void to the manufacturer.
They do have an anti-rollback counter but that is something totally different than a qfuse.

They only upped the ARB number because DirtyCow was fixed. Likely wont up it again until the next root is patched.
Doubt there is a way to mess with KDZ's to be able to make them flash. someone would have done it already.
Is there anything I should know in particular to 10k? It sounds like rooting isn't enabled unless i downgrade to another firmware version (is it even possible?).

Find the post with LGUp (restore even for bricked devices) and follow the instructions to downgrade. There are also some youtube videos which are very helpful, in order to downgrade or after, unlock bootloader and so on..
Hi all,
Have an AT&T branded V20 in Australia so not getting updates. Also can't use the hotspot without it being registered on AT&T network.
Want to know if its safe to flash a KDZ, thinking US99610N as its from the unlocked variant?
Have a few questions:
Is it possible?
Anybody know of a good guide to do it?
Risk of hard/soft bricking?
Possibility for recovering after possible brick?
Any help is greatly appreciated, been trying to find answers on my own for ages to no avail.
Thanks!
Root your phone, then flash the latest H910 firmware. There are two zips that are in the ROMs forum -- one will take you back completely to stock, and the other will upgrade you, but leave TWRP, you can decide which one.
As for flashing the US996 firmware, it may work, probably won't brick your phone, but there is no reason to...

Would updating to a newer H910 firmware still leave me with the issue of the hotspot wanting an AT&T connection? That's the only reason I thought to flash to US996 as its unlocked so would think that's the only way to alleviate the mobile hotspot issue.
Thanks again for your reply!
Search for 'H910 root' in News and DIscussions. I made a thread specifically for the H910 up to V10r.
Have you ever installed the mobile hotspot app for the carrier that you use on any other phone? If so, go into the playstore and search for it -- you will be able to install it.
For example, I use T-Mobile with my H910, and after I debloated all the AT&T crapware, I just went into the playstore and installed all the T-Mobile apps that I need. If for some reason that isn't possible for you, you can always side load them. The bottom line is, that while it may work, you will probably have more trouble if you flash another models firmware. There are exceptions, but why do it if you don't have to

Thanks heaps for your replies. I'm not trying to be difficult (but probably kinda am), I guess also my reason for looking at the US996 route is I live in Australia and that model was sold here, the H910 wasn't. So if I flashed to that wouldn't I be getting OTA updates, not having to flash every time?
Also with the hotspot, this is just a little bit of a foreign concept to me. I've owned plenty of Android phones but this is my first non-Nexus. All the others I've bought from overseas and its been as simple as settings>network>hotspot & tethering and away you go. So with this one I have to download an app? Seems stupid for something that is such a basic feature and is built into Android. I'm not sure why they bother with all this crap, stock Android is better in every way IMO.
Again really appreciate your guidance.
Well, all I can say is try it. It isn't going to brick your phone so bad that you can't recover, but the recovery process would involve you flashing the H915 KDZ and rooting. In order to do that, you must be at ARB 0, so make sure that whatever US996 KDZ that you flash doesn't increment ARB. Also, let's say that you flash the US996 10c KDZ and it works fine, but down the road you take an OTA that increments ARB AND doesn't work. You would then have no way to fix your phone.
Just trying to point out some of the pitfalls you may run into.

No I appreciate the pitfalls being pointed out. I thought it was the safer way to go but guess not... I'll take a look at your thread you mentioned earlier when I have a bit of time to actually do it. Or I'll just wait until a big update comes out, 8.0 or something. Thanks for all your help.
Is there any progress or hopes on rooting the ls997 running Oreo?
My device was unlocked for any carrier but after the Oreo update it has been relocked and I can't seem to find a way around it.
Rooting seems to be my best bet now. Plus I need to delete some super annoying Sprint apps.

I would say if you mean official Oreo, than no.
Anything after ZV7 atm is not rootable. Especially Oreo. Nougat might still have a chance. But Oreo is the nail in the coffin, if not the final nail. I personally am rooted on ZV7 and I can't even find an Oreo based ROM to run and try for LS997. Sprint's Kdz lockdown is my guess.
Carrier unlocked is sadly not going to allow root either unless somehow able to fully swap internal thoughts and memories of phone with another carrier. Even if able, it a slim chance if any.

You ever find anywhere else with a zv7? The one you linked got snatched up...?. I gotta make a dump for i95swervin and maybe he'll make a version of Alpha Oreo for LS997. I might be responsible for your lack of an Oreo ROM ?

We should start a bounty thread???

A bounty thread would be useless, most of the devs have moved on and runningnak3d has already stated root for 997 is a lost cause. If root is very important to you, then you should move onto another device

I would be down for a bounty thread, but I think it would be pointless as well.
As for the ZV7... That sucks. I wish I had another link but I do not atm and can't say when. If I see something I will let you know asap. Very rare now adays.
I also have a ZV7 dump I think on my laptop if need be from before I rooted.
ZVD rootable would be absolutely epic, I still have hope for someday as for my backup phones.

The eBay store of the seller who previously sold several LS997 ZV7's can be found here. He periodically relisted the Sprint LG V20 on there over the last couple of months (I bought two ZV7's on two separate occasions), so there's a slim chance that he could still have another ZV7 left among those that he sells. You could contact the seller to check.
As I have stated in another thread, I have a procedure that I am confident will work, but it will require significant development time to get kexec working.
The procedure would not be easy (if you think lafsploit is hard to do .. you haven't seen anything yet). Also, it would be a tethered root .. meaning you would need a PC every time your phone is powered off. If you just needed to restart the OS, that could be done without a PC, but a cold boot would need a PC to enter some commands via a shell.
If all of that sounds like something you are willing to deal with, then start a bounty thread and I will try to get an exact estimate on the amount of dev hours I would have to put into writing the code.
If you Google "kexec loading a kernel from a kernel" you will get an idea of the amount of work I would have to put in.
By using kexec, we would use a validated kernel (one that passes dm-verity) to load another kernel with dm-verity disabled. Since the first kernel already passed the checks .. the second kernel would be loaded without the full boot process, and therefore aboot wouldn't verify it.
EDIT: Oh yeah, you would also need an SD card in your phone with a partition to hold kexec, the kernels, and TWRP. You could use the rest of the SD card for the OS, and the partition wouldn't need to be very big .. but just throwing that out there.

I never looked into lafsploit because I don't have an H918. Just ls997..one rooted ZV7, and two ZVD's (backups). However...that method would seem a lil tedious, but doable. If only way...
I was wondering if it is even possible or easier to do and full on 100% phone clone. Turn one of the ZVD's into the rooted ZV7. That would be a true game changer and way faster.
If this was not intended at me I apologise. However, just a thought.
Once ARB has been incremented you can't roll back to any version that has a lower ARB. Even if you replaced the NAND, you would still only be able to use ZV8 or later since ARB is incremented inside the CPU. So, you can always replace the CPU AND the NAND

Oh yeah, I forgot about it being baked in the CPU..damn it.
Reminds me of PS3 and nand flasher crap. Damn all the lock down. Oh well. At least I have a replacable battery .
Sad year so far
My beloved fully rooted ls997 died with a sudden rpm crash that was unfixable ?. Cant find a different one for the life of me. Anyway, I am now on ls997 oreo with temp root. Its nice, but very limited. I miss my full root.
I noticed that I have oem unlocked which is supposed to unlock bootloader or allow. But this supposed arb screws it up. How I have no idea. Its all rom related so it absolutely makes no damn sense. Why have oem unlocked if we cant do anything?
So oreo full root with arb?...
Would a stock Oreo dump allow for kdz extraction to make a rooted/ rootable rom?
Just a question and be cool if so. Long shot I know.
Especially with a not yet known arb bootloader
