My Flex2 is LS996ZV4, i bought it in Cuba. It never got any OTA update since i rooted it very early and the software update notification didnt showed up there. Im living now in Peru and the notification does show up (by the way it can be seen in the screenshot), but... the update does not work because the phone is rooted and i find no way to unroot it due to its old software version(V4). Im in some kind of a loophole here
In the mean time, my phone overheat and lags like crazy! And i've been using it like this for almost a year now...
I asked this before, and i got no response, guess is not something easy to do.
Thanks in advance. Any tips will be higly appreciated.
Do some search in the forum and you will find similar threads about this issue for H950 or other variants check if it applies to your model or try it on your own if it works good then you are fine if it doesnt you will have to wait for professional support by other members who have exp with this device
Thanks for the tip @yeyoo. Im starting to believe there is no solution at hand...
I have searched... and almost every advice i read implies going back flashing the stock image and unrooting. But i cant do It because i cant find an image of this old software vers.(v4) to download.
I think you dont need the same version you have you can flash higher version kdz easily and it will remove root automaticly or you can try to update through lg mobile support tool on a pc
Hello everybody,
I usually find my answers in the specific phone related forums. But this time I'm stuck.
A friend of mine bought a Samsung Galaxy J7 (SM-J700F to be specific) in India. After using his phone there he came back home to Israel.
His phone didn't worked here for some reason and he went to a phone lab which flashed his ROM to stock Israel ROM.
They called him in the middle of the process and asked him what was his Google account thet he signed to while the first setup. Unfortunately, he cant remember his email address.
I took the phone to try bypassing the frp lock.
After a small search I realized I need an otg cable, which I bought.
I received the cable (1.5 mounths wait) and tried the otg cable method with no success.
After some experiments I successfully managed to open the settings menu. Pressed factory data reset and after a restart it stopped on recovery menu with the yellow message "dm-verity verification failed".
Well, this is annoying. I realized I need to flash the stock ROM again(Dated 01/16). So I did And the message dissapperd.
Back to the FRP lock issue. I did the process again and it didn't stopped in the recovery mode this time and I could see the Android logo with a little erasing.. Under it. Finally I thought.
I was wrong.
The FRP lock is still there! Dammit.
It is time to pull the big guns.
I thought I will flash the OLDER version of the stock ROM. Dated 09/2015 I Understand google updated the FRP lock protection on January 2016. Is the downgrade OK? I don't know if a downgrade is possible on Samsung phone.
And if you have an idea how to bypass this. Please share it.
Thank you so much!

im sorry if this is in the wrong section but ,ok so i bought an open box galaxy s6 from becetech online and it would not let me update the firmware past 5.1.1 which made me a bit suss, downloaded root checker app and it came too me rooted. apart from not being able to update the firmware past 5.1.1 as far as im aware the phone has no issues and works perfectly fine. i downloaded the *samsung* phone info app, in general under manufacturer it says Samsung/verizon so im assuming that is part of the reason they rooted the phone as it needed to be unlocked from verizon to be refurbished? so what i want to know is how do i find out exactly what becetech have done to the phone and is there an easy way for me to update the firmware to nougat or at least marshmallow without stuffing the phone, like i said the phones running fine its just really bugging me not being to update. obviously im not able to work it out myself but i can follow instructions so any help from someone would be greatly appreciated so thank you in advance.

Could someone with a bit more knowledge please tell me if the reason I can't update the firmware is because the firmware csc is TGY when I'm in Australia or just because it's rooted or what? I'm getting no answers from the company who I bought it off

Are you trying to update via the phone update feature? If so this won't work as rooting disabled the ability Update using ota
First I tried OTA then downloaded samsung smart switch and gave that a go both no good. What I want to know is, if they had to root the phone to refurbish it will it brick it if I try to update? Won't it reset all the company I bought it off has done to it to refurbish it? Which I'm guessing is quite a process as when I look at the open source licenses there's a long list of files that have been changed. It just sucks that it's locked to a three year old version of the firmware that I'm worried apps will start to stop supporting in the near future? Apart from that I can not fault the phone there's been no problems, maybe I'm asking a bit much for a $400 phone?

From what I can tell you have a g920v variant if the phone Shows Verizon but the sure fire way to know what variant you have is turn the phone off once off hold home-power-volume down, this will take you to download mode but should tell you your variant. You don't need to root a phone to refurbish It, you can flash Stock firmwares via Odin. I really don't know why they would have Rooted It tbh, you'd need to contact them, but I know for sure you can manually download the latest Verizon firmware and the phone should work. Maybe they Rooted it as part of making it network unlocked, o really can't say
Ok I tried that and a bright blue screen came up warning about custom OS then press up volume for download and down volume for reset? I just pressed down as there was no other info on the screen but it does say it's a sm-g920v in the settings as well as the root checker app. Another thing was I did ring samsung support gave them the serial number and IMEI and they said an authorized modification had been done on the phone but could offer no other support as it wasn't an Australian phone. I'll keep trying to get some info out of the company I bought it off and try to sort it out thanks for your help :good:
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.
I'll let you know if it's ready, hopefully won't be long.
Thank you again!

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

Here is the test point. Is it visible?
can anyone please post H90022b kdz file or something newer?
I have a question, how can I use QFIL to install the firmware?
Yesterday I tried to update it to android 12 but I got the error ¨Anti rollback¨ and it didn't turn on anymore.
Then I read a post from a user on reddit who recovered the files to restore it, but the truth is I already looked for the procedure to do it but it won't let me, I would really appreciate it if someone could support me, I attach the post.
