Root/downgrade options for H81020n

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.

You need to use LGUP

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

How to Edit KDZ/TOT for Cross Flashing

Kindly understand the scenario 1st.
Your Board is VS990 but It Comes With a ROM of H900 Lollipop. NO OTA Update.
And LGUP or LG Flash Tool wont let you flash a VS990 KDZ/TOT over H900.
02 Things Needed here. 1st Is LG Generic Custom LGUP_8974.dll and
2nd you have to Edit the file in hex editor.
Open VS990 TOT File and search for LG-VS990
Change
LG-VS990 = LG-H900 (Conversion) (Becuase Current Rom is H900, We will Deceive LG Check Thats a H900 file is being flashed which is actually a VS990 File)
Direct Overwrite no deleting.
You have to Direct Overwrite the file.
Although its the procedure OF Cross File Flashing.
But AS LAF (Download Mode) Recovery and other files are Of H900 so After Flashing VS990 The Mobile can be Hard Bricked to Qualcomm 9008 Which have no Solution Yet.
I dont Recomend IT. On devices higher then G2 and G3 (D851 Also Not supported in LG Board Diagnostics)

You have to over write the model no. In hex editor. Adding or deleting will change hex value. So file wont be flashed.
Successful flash can also lead to hard brick. LG Board diagnostic cant de-brick models higher then G3.

Okay, i saw also that people commented that they got hard brick. Is there anything i can do with the 20w rom to get my fingerprint scanner back? or just buy a new phone and call an end to it? If so i was thinking about the V20. Should be good for root and such right?

Hello Murshad007 and others,
it seems that you have a risky solution about the MM H900/VS990 - VPN -Fingerprint-foced-close issue with h90021w.
I also have the bugs after flashing "web_h90021w_00_0921.kdz" on my AT&T H900 with VS990 Mainboard (I have checked like in the Video).
1.) Where exactly can I Identify more "Frankenstein" parts?
2.) Which part configuration did you try successfull without hard brick?
3) If you had a hard brick, how did you recover exactly?? Would I need a programmer device like Medusa or a JTAG or is it possible to make the Frankenstein alive without spending 150$? Because that is the Phone's price ?
4) Could you maybe make a Tutorial or link any recover after brick solutions/possibilities please??
Now the phone is absolutly useless, so if I brick it, there won't be a big difference.
I would be verry happy to get some help fixing my new 30th birthday present
Thanks in advance
Evtoda Gi

Murshad please help us out with more precise tutorial on how to successfully edit firmware for cross flashing. Thanks

i have been scouring all over the forums to no avail, and i think the ansswer maybe really simple, some members have found the correct way but are just beating the bush cause they want money, and that too, way more than the price of the motherboard, which is less than 50$ u.s now,
I was successful in bringing it from the dead (H901 to h900} but the lack of security and fingerprint is really proving troublesome not to say the lack of Sim connectivity,

Open your Phone. Check its Board and Flash Accordingly.
Use Board Diagnostics for Full Flashing. All Functions will return.

H90022b Software update,October 12, 2017

I just upgraded two ATT LG V10 to H90022b released on 10/12/2017.
I thought it's just security patch but somehow I feel both get snappier.
And power seems improved a little bit. But I am not sure... maybe it's because it reinstalled all apps during upgrading ?
anyone has any issue or any improvement after upgrading to H90022b ?

ajutama si pe mine te rog frumos cu ultimul firmware lg h900
---------- Post added at 01:32 PM ---------- Previous post was at 01:28 PM ----------
am probleme de securitate dupa update android 6 pe lg h900
am nevoe de firmware ATT LG V10 la H90022b si nu stiu de unde sa downlandez
poate daca fac update la lg h900 cu H90022b mi se va rezolva problema

Have 2-week-old Lg v10 H900, new, unlocked. It would not upgrade with LG Bridge or OTA, saying "device may be rooted". So went online and found Marshmallow KDZ file and uploaded to phone. It shows the Marshmallow is up but now I get errors like "com.android.settings has stopped", "LG VPN has stopped", and "lock screen settings has stopped". I cannot configure/initiate fingerprint scanner, and device reboots when I uninstall an app.
I have cleared all caches and reset to factory (recommended by LG tech help...waiting for additional solutions from them), all to no avail.
Any ideas??

I have the same problem I am facing the same error in setting app if you fix these
If you fix these error please help me out

can someone with this update share it please as some of are not getting the update ota.

wow, it's been a year.. not solution yet? i wish i had this read these threads before updating to MM ...

Me too..
Wish someone with H90022b is generous enough to extract the partitions of the device so we can flash it using Qfill. As long as I have the device, I promise to do my best to provide the other files such as the loader and xml files.
I dont really understand the purpose of these partitions, so we need all except modemst1 modemst2 fsg (where imei is stored), cache, and of course no userdata. The total size will be around 4GB but will be around 2GB compressed.
No harm but will help a lot for many of us.
If anybody wants to help but not sure what to do, feel free to contact me.
Thank you!

Problem with extracting partitions once on 22b would probably require root (at least for methods that I know of, such as Wanam's 'Partitions Backup & Restore'. Besides, most users who rooted it on lollipop never upgraded the software, users who would have 22b installed can't achieve root, and developers who could really help with this have already moved on. I just bought the AT&T version of this phone to use with the $10 Unreal Mobile unlimited monthly plan and realized that there is no root after MM update. I could live without root but I am also stuck with outdated 21z.

Fortunately there's another way.
We have to get the phone to Qualcomm 9008 mode.
There are 2 safe way to do it, I said safe because I did both a thousand times (hyperbolic, lol) without any problem or effect to the phone if it just "reading/extracting".
The 1st way is to connect 2 points on the board while connecting the usb cable to the computer. Of course the board need to be taken out from the phone.
I understand if the 1st way may not comfortable enough for some, then the 2nd way is using a deep flash cable, which is an easy mod to a spare usb cable.
If I have a 21z or 22b device, I can create these files in less than an hour and potentially help many 90021w user.
Both may not an easy thing to do. So will be great if anyone willing to lend a hand.

Hello,
Thank you for your efforts. Sorry I was a bit busy these days.
Initially I'm trying to get my luck by googling up what I see on your screenshots, but no luck.
Now I'm still trying to get a script to copy the phone's partitions. Seems like will taking a while.

You welcome. I also tried to download a kdz for my firmware by using LG Bridge's 'update error recovery' option but it gives me error that "Your phone information cannot be checked. For more information, contact LG customer service". But if i use just 'Software Update' it tells me that I can update to latest version "V21W_00" through update center settings in my phone. I think that LG Bridge database only have up to V21W as the latest OS for LG H900 and it doesn't recognize that my phone has more updated version, so even if someone had Nougat they got OTA, they wouldn't be able to use LG Bridge or PC Suite to help us this way.
I am just tired of this phone and gonna sell it and buy a T-Mobile version. Good luck to you, hope you find a way to upgrade software on your phone.

I read somewhere that after 21w, at&t keep the firmware on their server, maybe that's why the only way to update is through OTA.
When will you sell the phone approximately? I may finish the script before it..

Maybe it will change something if we get the H90022b .. i'm little skeptical though. Because our issues with H900 MM started because we Flashed a H900 ROM over a H901 or VS990 board. the way i see it, even if AT&T releases Nougat, we still gonna have issues, even worse.. we kinda screwed..
i've been thinking, maybe the H90021w was somehow corrupted or missing some files...
Also, i've been reading some threads, people talking about reflashing the correct ROM, either a H901 or VS990 ... but i'm not ready to dry that considering none has done that succesfully..
For me, the solution would be find a solution to go back to Lolipop... at least it no issues. outdated maybe, but everuthing was working fine on my phone.
https://cdn-cf-3.xda-developers.com/images/smilies/cool.gif

Going back to Lollipop is not possible because of antirollback. And I dont think if there's anybody ever found code board H900 on the pcb. Eventhough it seems not right but vs990 is the correct pcb board, it just the bad firmware (v21w). And there's no KDZ or TOT newer than v21w around as far as I know.
I think I found the solution, but I need a volunteer with v21z or v22b firmware on his phone

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

Just double checked sorry about that, yeah got that file back in March it’s even in the OP links. Yes you can flash that. Just be sure you have an actual H810 or you’ll really screw up the device when flashing.

Hey Hyelton,
Thanks so much, I appreciate your help so far. Do you have instructions for flashing? (havent flashed LG before). Can I use LGUP and if I do, what do I select? refurbish or upgrade?

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?

Just an update; opened the motherboard, its a H810. not sure why I'm having this security setting issue. also, funny enough, I can now update software directly from AT&T server. My 20y is now 22c! if I can just fix this "unfortunately, the process com.android.settings has stopped" error on the security settings, I will be fine.
Please anyone have a solution to this?

Sadly that error is symptom is common across a lot of AT&T G4s both faked and real. Only fix is to have its board replaced. There’s no fix for it.

Ok, can a custom MM ROM be installed on this board? do you know any that can be installed on H810?

Not sure if there’s any custom Roms for the H810 but if there are you can’t root or flash them since you have upgraded.

Android 9 Pie .kdz

Well I've obtained the actual .kdz file from the pre beta program in Korea. Now too flash it into my Canadian g710awm. The firmware is actually for model# g710N so wish me luck...

Is it a 8.0 kdz to update to 9.0 or directly a 9.0 kdz?

Did it work?

Lack of response, I'm gonna guess no? LoL

dah brick dah bricks.

???

The suspense is killing me. Personally I'm waiting for the official, but it would be nice to know...

i guess i would be able to flash it on my g7 , but i only have a .up file instead of a kdz and that doesnt work

Warning!
From what I read recently; LG has started to use unique RSA keys for each device (within a group, i.e G7) starting with V35 (I think), thus flashing a KDZ from another G7 would definitively cause hardbrick.
Edit: Apparently this was (mostly?) wrong. At least some confirmed models can be cross-flashed.

I thought that was only for TMoile but not the rest of variants?

Well, like I said, not anymore.
IIRC, this is what @runningnak3d said in a tread somewhere (I don't recall exactly, maybe V30 forums).
He is the current resident expert on LG root, and bootloader matters. At least the most active one, and he's provided root for many previous LG devices.

I am definitely not arguing as I dont know the answer 100% myself.
What I DO know for sure is that I can, (and I have) flashed other LG G7's firmware on my G7 (Sprint) through my Octoplus box. This is using the Octoplus box, not LGUP, but if the RSA keys were an issue, I would expect it to not work (flashing another variant .KDZ), or I would expect the device not to work (boot) afterwards. It boots and works just fine. I also know of numerous others who have converted their LG G7's (except TMobile) to the unlocked model (ULM). My understanding was that only the TMobile ones were using a custom RSA key coming FROM TMobile themselves (I could be wrong but this is what I read) and since I dont own a TMobile flavor, I cant test myself to confirm.

In that case maybe I remember wrong, or runningnak3d statement was not accurate (maybe doesn't apply to G7 specifically).

All good, I dont know for sure myself so I cant confirm nor deny anything except for my personal Octoplus flashing. I just want ROOT, thats what I am pressing through to figure out how to achieve. I HATE that LG locks the bootloaders, if I had known prior, I would NEVER have switched from HTC!
LG mobile will go out of business soon enough if they dont cut the crap.

Yeah, not to mention that we don't have a way to fix ourselves bricked devices. It would be a trivial matter with a simple qualcomm type firehose-file.
Instead now it's basically dead weight. They seem to think it's ok to produce lots of electronic garbage, and not make efforts to reduce this.

Exactly, hopefully the drop in sales will be enough to kick their butt's in gear BEFORE they become the next Blackberry! If they would simply give us a restore KDZ, we would love LG, instead, they lock us out, and make it damn near impossible to restore or recover our devices from normal things, such as a bad OTA updates. BUT NO, for some dumb A$$ reasons, they dont so it WILL be their demise. Its almost like being able to see the future. If they took notice of all the predecessors before them, all their mistakes, made changes then history wouldn't have to repeat itself. If not, LG will be another forgotten company no one gives a crap about.

What partitions did you flash?
All of the KDZs I have been able to pull down have different RSA certs (granted it is only a couple) but it is not just the TMO that was different.
If you don't mind, link to the exact KDZ for your model, and the KDZ that you flashed -- I would love to compare the certs.

There is no KDZ for the PM (Sprint model) yet so I cannot go back to Sprint or link to one (until one is released) but I wish there was one for others who are in a loop or brick situation, here are the 2 I used:
EM (European Model - bootload unlockable approved by LG):
G710EM10b_00_0521.kdz
https://drive.google.com/file/d/1W14Y-jbvnwDt4UOfitni8hDGfwYsXesV/view?usp=sharing
ULM (US Unlocked Model):
G710ULM10g_00_NAO_US_OP_0913.kdz
http://pkg02.lime.gdms.lge.com/dn/d...XADM55F9FR80/G710ULM10g_00_NAO_US_OP_0913.kdz
I flash ALL partitions through Octoplus EXCEPT the modems (MODEM1/2), I left those from Sprint (stock), not sure if it helps or not, but I have service so I like to think it did. There are lots of users who have also used the LGUP (somehow) to cross flash the KDZ's to the ULM (unlocked) model but I haven't personally used this LGUP method so I cant comment if its valid or not. Octoplus, most definitely works though (and I have the logs to show the partitions if one was interested).

There will never be a Sprint KDZ -- neither Sprint or AT&T release KDZs (I don't think they even use them internally).
I am downloading them now, and I will pull the certs / post the results as soon as they are done.
Thanks!
