I had to make an insurance claim on my AT&T G3 recently and they sent me a G4 Android 6.0 / h81020n, build MRA58k. From what I understand, there's no way to root it and many don't expect there will be for a while...is that right? If so, what are my best options to downgrade and then root it? It's my only phone, and though I'm extremely competent with this stuff, I need to be sure it's a surefire method of downgrading. Thanks

As of now, I'm going to be bold with my statement about the G4: The AT&T cannot and will not ever have an unlocked bootloader. I would also assert the likelihood of root on Marshmallow is slim to none. I'd say "none", except there's always a remote chance that someone with the time/money/know-how will decide not to give up until they've figured it out.
When you say "downgrading", I presume you mean going back to a previous build? If so, it is not possible. It would require the level of access that only an unlocked bootloader could provide, from what I understand. I think there was mention of some sort of bypass option that works on other devices, but it doesn't work with this one.
Long story short: get comfortable with your current experience, because it isn't likely to ever change with this device. I too had to replace my device under warranty (for the 2nd time), and was bummed when the replacement arrived having Marshmallow on it.

I have not been able to downgrade H81020n since I got a replacement phone due to the infamous bootloop issue. I'm starting to wonder if somehow AT&T with or without support of LGE figured out which phones were rooted and injected some network packets to stress the radios in this device causing failures.
What's really unfortunate is the replacement devices all come with Marshmallow 6.0 on the H81020n ROM. That locked-down image, with the locked bootloader have made this device much less fun.
I've tried several downgrade paths with no success; the low-effort Root method, TOT downgrades with the LG flash utility, and good old fashioned send_commands.exe for image restoration to stock.

Did you load the.tot, close the LGUP program then reopen it and attempt the flash?
Did you change the Port # in Device Manager?
Can the same downgrade be done on 21y for h810 I miss root

This is a thread for the progress of MM root on the AT&T variant of the LG V10. I am working to find a way to root it, even if it is not through a TOT, but a exploit.
I know some of you were wondering about my donate info, and so I decided to go and set up a Paypal if you felt so obliged haha. (Its in my info in my profile)
Right now I am examining a TOT that someone sent me and I will determine if it is corrupted too, or if we have a shred of hope. Wish me luck! Will update later if it is found that it is bad, which I expect.
Ok, so I just compared this TOT to the one that iBowToAndroid sent me, the 2nd time. They are practically identical, regardless of them having different MD5s. Although if anyone feels like actually testing it before they go to better phone, feel free. ha
If it will be possible (and when you will find a way), please, make possible for H960a too.
Well, i am happy to see someone is making progress on the root development on MM, at least, make the community alive.
However, MM needs systemless root and the old way by injecting su binary to the TOT will not work at all.
I am not going to discourage you, unlocking bootloader should be the only way to root MM.

Unlocking bootloader is something else I currently working on, if the su binary inject does not. Right now I am planning to pull the entire systems contents by soldering off the storage chip and reading it using some hardware of mine. Once I copy all of the partitions over, then the fun begins

The KDZ files used by LGUP include an image of most of the flash used by the system. A few portions are missing, but not very many, notably the "misc" portion is absent. I believe the missing portions are ones that would be unaffected by rooting, so you could get most of the data out of a KDZ file and then root to get the rest of the data.
Aside from the key for the bootloader potentially being in the "misc" area, I also noticed there is noticeable amount of space reserved by the GPT, but unused. There is also a noticeable amount of unallocated space between the GPT and first slice (the "modem" area; this could be for alignment purposes, but it could have other uses as well).
Hopefully LG will be persuaded to unlock the bootloader of all V10 models, but I'm a bit on the pessimistic side at this point. I also hope the unlock mechanism will be shared by all V10s, so we don't need to reproduce it for each device. I haven't done cracking before, but I hope to target the H962 and be able to install full mods in the future...
How goes the progress ZVNexus? Thanks so much for embarking on such a journey for the sake of us all. I loved the flexibility of my Nexus 6, but it was so much weaker than the V10 in so many areas...especially the camera functionality and the ridiculous amount of sluggishness during normal tasks. I went through around 10 of these phones due to QC issues. I'm happy with my V10 (at&t gave me a replacement since I warranty returned the nexus so many times). But, it's just not the same without root and unlocked bootloader. Thank you again!
I found this today..I am sure you have seen it but I figured I would put it here anyway. I downloaded it but figured someone smarter should look before I tried to flash it. I cannot post it. Someone posted it on the original mm tot download thread..it was posted by radical.
In Theory...
In theory...
Are stock MM KDZ files available for the AT&T V10? I haven't seen them in the KDZ thread, but they may be posted in the AT&T area. If so, it should be possible to use my KDZ tools to unpack the KDZ, then install Superuser in the image and then repack the KDZ and tell LGUP to install the modified KDZ.
At the moment I'm cautiously optimistic about the KDZ tools. I've got all of the fields inside the files identified, but there some hazardously big ones in the DZ header that are unknown. My tools simply copy those, but I worry. Also SEEK_DATA/SEEK_HOLE are available on Linux, but likely not on Windows. (hack: replacing SEEK_HOLE with io.SEEK_END at the top of image2chunks.py should work around errors)
any update on this project?
I follow the V20 threads and all the V20s have root now. From what I read they used a debug boot.img from a Developer V20 and extracted the boot.img and used an exploit from the DirtyCow Root method to flash it. You have to really be involved to root it.
Just seeing where this can take the V10.
Any Update?

Nope. The hope of root for this phone was crushed long ago. Almost time for everyone to get new ones.
I am going to upgrade my phone from lg v10 to v20. Can you confirm me that is every lg v20 mobile carrier version ROOTABLE or i should buy a specific version?

You’ll need to update via an AT&T sim. If it won’t update it an att sim you might not have an actual H810. A lot of people have problems with the phone after updating so I wouldn’t recommend it anyway.

Hi Hyelton,
Thanks for the super prompt response. Unfortunately I'm not in the US and do not have access to a ATT sim. even if i had, there is no network for ATT where I am. Based on my research online, others were able to update without the sim card using FOTA via adb and LGUp. I just don't understand why mine is giving me so much stress. The phone is a H810. Can send a screenshot of phone's software details page. I need the phone to be on Android 6 cos I need to install my office apps on the phone and only android 6 or above is supported.....

The phones software details doesn't show the actual model just the software installed. Just throwing it out there it's common when it comes to the H810 to be sold to someone and its not an H810. Especially if your friend bought it referbed

It’s in the guide/thread your posting in . Yes you would use LGUP and choose refurbish if you cannot select the tot choose upgrade, select the tot then go back and choose refurbish.
Some things to remember. If it is a wrong model phone flash will either fail and you’ll be stuck, or the update will work but under settings and privacy /password and a few other things will no longer be usable.
Also you won’t be able to downgrade once you flash this.

Hi Hyelton,
So I flashed the phone and the upgrade worked. However unfortunately, I cant get into the security settings, my lock screen settings is stuck on swipe(other lock methods fail). and phone wifi does not work with enterprise wifi that is secured. Do you have any fix for this? If this is a board issue, maybe I should open the board and flash it with the appropriate firmware for the board (ie: If H815, flash with MM for 815 etc)-what do you think?

1. I could put an "international" / "Debranded" software on my old Sony phones. Does the V20 have that? Or is it only carrier specific software? I would like to get rid of the T-Mobile crap on my H918.
2. I'm assuming if I root and/or unlock the bl in this phone, I have to say goodbye to Oreo and downgrade?
ALSO, if so, would you recommend I do that anyways? I feel 8.0 brought a lot of cool features to the V20.
I've spent a lot of time tying to figure out the answer to #1. Poking around. But not sure if "OEM" means T-Mobile's software on the V20 or LG's generic software. (If that even exists)
I guess my goal is to just get rid of T-Mobile's crap on this phone. I switch to Google Fi.. Wich may have been a mistake, too .. who knows. It's just a cheaper t-mobile on this phone.
Much thanks for the help. This site has helped me de-brand old pre-Android SonyEricsson phones and unlock a bunch of helpful stuff. In great debt to you folks.

You can't flash another variants firmware on an H918 result is instant brick. You can downgrade to 10p and root via the laf exploit and then upgade to oreo with the rooted Oreo zip in the forum and keep root, there are a couple custom stock based rom which has some stuff debloated, if you choose to debloat further be advised that if you remove the wrong thing it breaks stuff in the rom

Yeah, grab yourself the modded version of LGUP, download the KDZ (Most likely US996) and flash it. No root involved.
I'm in the same boat as the OP, in the UK.
I broke my International version HD990DS which I've had for a couple of years, and scored a replacement H910 on ebay (£115, sealed in box, 2019 date on battery). I received it this morning.
I wasn't aware when I bought it that it was an AT&T brand (unlocked), on Android 7, and un-updateable OTA here in the UK.
The kdz I'm downloading is 'US99620f_00_1120.kdz' from here: https://www.mylgphones.com/unlocked-lg-v20-us996-received-oreo-update-us99620f.html
Should this be good to go? I'm not aware what bands this enables. The bands EE use here are 1,3,7 & 20.
Is there a 'better' kdz I should be downloading?
TIA.
[edit] further to the above, for any UK EE users, the page here gives EE APN details which will need inputting if your phone isn't going to be a wifi only paperweight. Other operators and phones are listed in the site:
https://apn-uk.gishan.net/en/apn/ee/lg-v20
In this page you'll note EE does not support the H915 for 4G at all.
The H910 isn't listed, but it is supported for 4G by EE.[/edit]

to flash cross model use partition dl mode, select all partitions. iirc
(not applicable to you specifically, but as a reminder to anyone else who reads this)
Remember, never ever flash (T-mobile) H918 firmware on anything but an H918, and if you have an H918 never ever flash another model's firmware. Instant permanent brick.
Thanks for your input. I'll give it a go tonight.

Did you manage to get oreo on H910? My mother has a H910 stuck in Nougat, but I'd like her to get the oreo update without having to mess with root or anything hard for her to use.
Not yet... I'm waiting until I've had the crap annoyed out of me enough before I invest the few hours time to put everything back on this phone that I want.
As all partitions have to be rewritten then its a case of starting from a totally fresh phone. Which is a chore that I'll do sometime, but not until this week at least is of the way....

Lgup patched linked above using partial download you can load Oreo from us996 or h915. H915 = H910 only Canadian version with respective network software.

I'm using H91520a_00_RGS_CA_OP_0717.kdz
Downloaded from LG-Firmwares here: https://lg-firmwares.com/downloads-file/...
IIRC it was the world's slowest download, reminiscent of using a dial-up modem (well, almost).
The H915 is the canadian version of the US H910, so no worries about hardware incompatibilities
Update in patched LGUP (using 'partitions.dl' option) took about 5 minutes and was painless (one warning screen popped up at start of f/w update process in LGUP saying USB was disconnected, but I ignored this throughout the update and left it showing) .
APN numbers need to be added
I backed up data (phone logs, messages etc) first in LG Mobile Switch app first, saving to SD Card. Which I took out of the phone first before the update 'just in case'.
No more AT&T crap, and Android 8.0.0, which is back to how my last V20 990DS was before I broke it (water damage).
It's a bargain phone for £120 on eBay. Good luck!
I've been trying to flash my G900 (AT&T version), So far I've tried LGUP, LGUP Dev and The official LG flashing tool, My main goal here is to at least remove AT&T from the device as it's throwing me errors when I try to update from Android 10 to Android 11. Any suggestions? I've searched around and there doesn't seem to be much about thus specific device.

I've been trying to flash my G900 (AT&T version), So far I've tried LGUP, LGUP Dev and The official LG flashing tool, My main goal here is to at least remove AT&T from the device as it's throwing me errors when I try to update from Android 10 to Android 11. Any suggestions? I've searched around and there doesn't seem to be much about thus specific device.

What are you trying to flash exactly, and how are you trying to flash it?

Well basically I'm trying to crossflash the device with a clean firmware/OS
I have confirmed numerous times it should work fine, as the devices are identical; only distinction is firmware.
I have used all the LG flashing tools I can find, They all see, connect and flash, only to fail with an error, that's either blank or changes every time.

So which firmware are you trying to flash, exactly?
I have tried anyway with LGUP. A bug for protection does not allow anything. I want to upgrade to 11. Nothing at all. The dll I extract it from the Firmware and neither. Firmware from Lg-firmwares.com for this AT&T Velvet 5G.
dude you'll never install anything LG directly gives you since you can't unlock the bootloader

Uhhhh, the bootloader doesn't need to be unlocked in order to flash stock firmware. That applies to almost every model from every manufacturer

I understand what they say about bootloader unlocking. It is true the majority, the vast majority do not need it. But this AT&T device has made my life impossible to do so. I also can't find a way to unlock bootloader.
Please, someone who can give me a good tip, of what I have to do. On the other hand, can someone explain to me how to extract the KDZ from my own phone. I'm not talking about downloading a KDZ but about making a backup of the device itself. As you know, the bootloader is not unlocked and I would need a tool that allows it without having to root it.
