Help please. Update rooted flex2 with old software vers - LG G Flex 2

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

[Q] In desperate need of help regarding S2 stock firmware!

Hello Xda! I hope you've all had a wonderful christmas eve and an even better new year! I've joined this site after headhunting and reading numerous posts touching different topics regarding one subject and one subject alone: Samsung Galaxy S2.
Now, on to the issue at hand. After tweaking and modifying my firmware, in hopes of getting Cyanogen 7 to run along with the ICS theme for it and having failed, my Sg2 has never been the same, of one simple reason: I haven't found the exact stock firmware that fits my phone. When I write "fits my phone" I actually don't refer to the fact that they aren't working as they indeed are, but no-one that's up to date.
The problem could've been easily fixed if Samsung Kies actually worked with my Windows 7 64-bit, which it doesn't, and please, don't point me in the direction of other posts such as "untick debugging mode", "reinstall Kies", "install those drivers by searching 'this' and 'that' on Google", because trust me, I've tried everything. It worked for a couple of days, but now as I really need it, and want to get out of the hellhole I call "KE2", it doesn't seem to want to help me, at all. "This device is not supported by Kies".
Now, I've visited another thread here on xda, more or less this one: http://forum.xda-developers.com/showthread.php?t=1075278 and dabbled myself through numerous versions until I finally settled for XWKE2 - Generic NEE and successfully managed it to run on my phone with Odin.
Since my phone is operator locked and I'm paying for it monthly via a Swedish operator known as Telenor I'm not able to update the firmware via About phone -> Software update either.
As I said, Kies isn't able to update my phone to 2.3.5/ KE7 (or whatever version is the newest) and I'm thusly stuck with XWKE2 & 2.33.
The most major problem I have is that I don't know which firmware to download from the topic I provided above, and I'd really like to know which one to actually download in order to have the most up-to-date version.
I'd immensely appreciate any help!

bought phone from becetech wont update firmware

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:

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.
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

I can't update OTA my LG V50 V450PM

I have a problem with my phone that I cant be updated. I found many times on internet about its rom, on lg fanclub but there's no kdz file for v450pm. Can you guys help me with this problem??? I went to setting and it show software version v450p10n although my friend also have a LG v50 v450pm like me but his phone show v450p20h and android 10. Can u guys show me the tip?? Lots of thank!!
wow, lots of help you got there.....
I TOO WOULD APPRECIATE ANY FEEDBACK!
I am literally days away from buying one of these new (V450PM), because I'm done waiting for the NAO kdz(android10) for the V35. Apparently, regardless of all the BS press releases and "schedule leaks" and ChazzMatt imploring us to be patient, THERE IS NO WAY TO UPGRADE MY V35 WITHOUT KOREANIZING IT!!!
If I buy one of these (V50, new, unlocked), am I going to be able to get Android 10 on it, or just continue pretending to wait for a kdz that's never going to happen???
Thank you in advance for ANY light yall can shine on this...

I have been on the same boat with my unlocked V35 which i use in Europe,and having no more hopes for it to get NAO android 10 so i can flash it,i decided to move on with an unlocked V50 450PM.
So as a responce to the OP,cause it is a double post,you can have a look to the following link,where i have given some answers about your enquiry.
LG v50 Sprint v450pm can not update OTA or flash stock rom
I have a problem with my phone that I cant be updated. I found many times on internet about its rom, on lg fanclub but there's no kdz file for v450pm. Can you guys help me with this problem??? I went to setting and it show software version...
forum.xda-developers.com
i am in the same boat, can't ota update.
this was a replacement from asurion. LG Bridge doesn't even recognize it is connected despite windows & adb showing it. Only get a blip of something from LG Bridge when i boot the device up into download mode.

LGV500N ROM- English version?

Ok, to make a long story short... I bought a refurbished LG V50 Thinq off of Ebay, not realizing that it was a Korean phone because IT WAS IN ENGLISH WHEN I GOT IT! I got another phone and was going to let a friend borrow it so I factory reset it... not only is it still all Korean, I must have tripped Knox or something because the touchscreen doesn't always work- I can tap on stuff til my fingers are raw and some options just never become available! I have successfully downgraded the firmware and then upgraded again using the Patched LG Flash Tool. I tried using the Flash Tool 2014, as it has a drop-down box that allows you to change the language but I always get a "failure to connect to server" error. I tried messaging the seller but he never replied, of course.
So has anyone got maybe a custom ROM that is in English? Or just some instruction on what needs to be changed inside the firmware? I'm still new to all of this and it's quite frustrating. Perhaps I installed the Flash tool incorrectly and that's why it isn't working...?
Sorry thus post is so long; I have been scavenging the forums for weeks and have not found a solution so any help is greatly appreciated.
