LG V50 Model 450PM Sprint Bricked - LG V50 ThinQ Questions & Answers

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.

Bricked LG Optimus Regard (Cricked)

It will boot to the LG screen then a black screen,
what happened: I rooted my phone, then installed beats audio (requires root) from App market place,
I did not back up my firmware, like an idiot.
So, I found this guide, [cannot post outside links, basically its a link to a LG Motion Unbricking guide]but I am worried it will flash my phone to Metro PCS. (I believe this will work because the Motion and the Regard are the same). Can anyone who has the Regard copy and upload their stock or rooted rom instead?
PS sorry for posting here, there is not section yet for the LG Optimus Regard
Well now my phone kind of works, it boots after flashing this Motion 4g rom, however, it continually repeats the message (as in loops) "Unfortunately, the process android.process.acore has stopped" moreso, I am now flashed over to Metro PCS.
Please I beg of anyone with this model the LG Optimus Regard LW-770
PLEASE My phone is unuaseable in its current state.
So I got it working..... except my phone still thinks its an MS-770 and not a LW-770. Also it is still on MetroPCS.
So I am saying screw it, can someone please just tell me how to change my carrier back to cricket. I will stay with my phone having the wrong model number until someone releases a proper rom

Help please. Update rooted flex2 with old software vers

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

LG g4 correct kdz ????

A while Back i tried to update my LG g4 H815T to marshjmallow using the LGUP method. I followd the thread on XDA.
When I was finished with it my phone got soft bricked. ( It booted up bu tgot stucj on the LG logo and blue LED flashed continiously.)
I tried using the same method but this time LGUP was not even recognizing my phone. Then I started searching for other methods i.e LGFlashTool but that didn't work either so I gave up on the phone.
The other day I was just sitting and realized thatthe issue may be that I flashed the wrong KDZ. Since the link that was provided to all the LG KDZ didn't have a file named just H815T.
Now I searched the internet but couldn't find out what KDZ to use. Any help would be really appreciated. Also, If someone thinks there could be another fix please do share as I'm not a 100% sure that i'll unbrick my phone even if I do find the correct KDZ.
here are the links i reffered to
the tutorial I used:

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

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.
