Safe to flash H91010I to US99610N with LGUP? - LG V20 Questions & Answers

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...

I've noticed there are a few methods for doing this, dirtysanta etc, which would you recommend keeping in mind what I want to do?

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.

LG V20 T-Mobile Rooting - Soo many threads; I have no idea what I'm doing

I've done a bit of research, searched through threads on this forum, and I still have no idea what I'm doing. The last phone I rooted was a Samsung Galaxy S2 Skyrocket.

First which firmware are you on now? 10i, 10j, 10k, what? I think 10k is not rootable. But... If you have older firmwares then you can root with dirtycow method. it is not that hard. I think the hardest part should be to try to flash the twrp (but even that was easy at least for me an average flasher and tester). If you have any issues, the system will usually restore to the original image as a last resort.

The 10j kdz version is to be flashed with LG UP if you needed it. but up to now it is better you dont move further from 10j, because 10k is not rootable (i believe I've seen). If you want to have 10k you can flash 10j and then flash via twrp a zip of the stock rom with 10k

T-Mobile LG V2010t
Hey all I new at all this and I'm trying to unlock or root my T-Mobile LG V20. I've never done any of this stuff, but I want to be able to use this phone on a network other than T-Mobile. Can anyone give this rookie ( me) some help?
T-Mobile won't unlock it for me. The day there is a balance owed on it. And when I tried the unlock app. It say failure in processing the request. Please reboot and try again.. If you can walk me through this it would be greatly appreciated. Thanks all!

Why did you reply to a post from last year for this?
Rooting has nothing to do with network unlocking the phone (and if it's on 10t or really anything past 10k it's unrootable anyway).
Your best option is to get T-MOBILE to unlock it, otherwise there are some other third party websites which may be able to unlock it for a fee.

I'm sorry my bad. I'm new here and did know how to start a thread. I just thought someone here might be able to help me. I didn't want to cause any problems.

FRP Locked LGV20 H918

Reading up on some things, Maybe I could flash it back to stock using LGUP (Not sure if i can do that without usb debugging and dev settings) and hopefully use dirtycow? I have no idea
Phone: LGV20 H918
Android ver: 7
Security Patch, May 2017
If you have any questions feel free to let me know, thanks!

Depends on the model. I've heard H910 doesn't have a kdz. If you can find a kdz for the phone, you can use LGUP or something else I've heard called UPPERCUT, which is the same as LGUP but better in some ways... I haven't done any flashing, especially since just unlocking the bootloader on my model is nearly rocket science.

H918 does have some KDZ's but I can't seem to find one for H91810D
This is the closest i've found so far. https://build.nethunter.com/misc/h918/v10d/
I have 0 clue how to flash that at ALL.
There's plenty of guides to flash kdz files. Wish I could help, but like I said, I haven't done it myself. Search around, see if UPPERCUT is better.

H918 10P root?

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!
Can't flash an su method if you can write to the boot partition (twrp)

So no way possible to root then? My V20 is running H91810k and I have been looking for a way to root it but moments ago it turn off by it self on 13% and the update for 10p was in schedule....
Guess Im out of luck if when it turn on update itself.
@joesee You were on stock 10p? If so, how did you flash TWRP so that you could flash SuperSU? fastboot flash recovery does not work with 10p.

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.

Has an ARB system ever been rooted?

We have a quasi-root with 10P, if starting from 10J.

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.

Need help to root H91810k

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.

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.

Yep, that means you are on 10k, so you are safe to rollback.

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
Build Number: NRD90M
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.

If you root your phone it will be unlocked no need to use an octopus box.

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

You need to pay attention to runningnak3d when he says something about root and the V20.

LS99720a - Any way to root JUST for deleted file recovery? Don't need other stuff.

Title. I no longer use this phone but I would _love_ to be able to get deleted stuff off of it. I did this in the past with my old LG G3 and never had any issues like this phone has with getting to root. I tried it when I first got the phone, tried it a year later. never worked. Now trying 3 yrs lol. Is there anything I can do or am I SOL?
@Phoenix591 already answered this for you on Reddit. I don't know what else to tell you.
Original Reddit post for anyone else who is reading
Thats an Oreo version, and so is past the point of no return. It's unrootable. Tiny electronic fuses have been physically burned to prevent it from booting rootable firmware.
As I mentioned the last version that has the ability to return to a rootable version was ZV7 (the actually rootable versions were ZV5 or earlier, however LS997 did updates weird which ment that firmware wasn't available to flash using the same tools other models use... If on ZV6 or ZV7 its possible to root by crossflashing another model's firmware briefly ) , which was a few updates before oreo came out.

Unfortunately, the LS997 ended up being more limited than the other carrier-specific models. However, root access is getting harder to come by on new carrier-specific devices in general.
