[LG V10 General] hyelton:
Its gonna be tough finding 20t if its even out there. I've done some searching so far nothing is available.
[LG V10 General] 2111002640:
Yes, i know, i have a solution, bút i don't have device to do that, use another v10 with lower ver 20t, upgrade ít via LG Beige, on the upgrade process we can get the firmware on this software
[LG V10 General] hyelton:
Hey,

Seems like it may be due to trying to downgrade may need to flash a newer firmware more close to what its currently running. All else fails try and use LG Bridge, but it will flash the latest firmware which may be whats already on there. You may not be able to downgrade firmware past a certain point now.

About your notification issue, sounds more like a background data/wifi use problem. Did you make sure background data was enabled? Theres a feature on the G5 that limits background data etc (forgot what its called)
[LG V10 General] hyelton:
Most likely the same that your phone is currently running. Which you may have to use LG Bridge since I couldn't find any newer KDZ files for your model.

Help

i Accidentally Flash H90021w on my F600k now Every thing is working perfectly, only there are no signals i try to downgrade it to F600k 20j but it soft Bricked only H90021w is working, Is there any way to get the signal back it Detects the sim card shows sim contacts but On Status bar Signals shows Cross.

Any Help Please
[LG V10 General] hyelton:
Why would you do that? You might be stuck on that firmware now forever due to antirollback.

No service is likely due to modem that is a completely different model you flashed, and or loss of EFS, if you lost your EFS there's no getting that back unless you backed it up.

You'll have to flash back to its correct model, but you may not be able to since flashing the wrong model firmware which has antirollback.
[LG V10 General] NIGHTMARE-:
How backup EFS ?
[LG V10 General] hyelton:
Root is the only time I've ever done it.
[LG V10 General] NIGHTMARE-:
There is no root available
[LG V10 General] hyelton:
Yeah I think root is the only way it can be backed up. The only time you need to worry about EFS is if doing something like above flashing wrong model firmware.
[LG V10 General] RiiiiZzZz:
i Tried to Roll back to its Original Firmware which id F600K20j But After flash is 100% done it wont turn on Again. Now only H90021w is the one which turns on my Cell but without sim.

If Lg roll out Nougat update which is not possible i think for V10 Then is there any change that if i flash F600k Nougat will it work ??

or if i back up EFS from any other f600k dose it work for me ??

And how can i backup EFS coz there in no root available for 6.0.

Can you help me in any ways to get my Sim Card working as well
[LG V10 General] hyelton:
[Guide] LG V10 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

If your EFS is lost it's lost. There's no getting it back. But in your case your most likely stuck on that Firmware with no reversal. At the current moment only fix is a board replacement due that that firmware I believe has antirollback
[LG V10 General] RiiiiZzZz:
What about if LG Gives Nougat for V10 and F600k As well will it work ? Coz downgrading is not possible may be upgrade solve my issue what is the experts Opinion on this?

And is there any chance LG will Give Nougat Update in this year ?
[LG V10 General] hyelton:
That would depend more on antirollback status if that changes for the F600k which most likely won't change.

At the moment that device is stuck on the AT&T firmware due to antirollback most likely. It's a unique situation here as no one has really had to go through it.

To go back to lp from mm lg v10 h900

Hello I have a LG V10 H900 and install V21w and now it has flaws, some functions are closed and it does not let me configure fingerprint reader, nor uninstall apps.

I want to install H900_20j or LGH900AT-V10F-ATT-ROM-Fix-HoangNova but I do not know how to install TOT, you can give me DLL files for this model please.

Thank you​
[LG V10 General] hyelton:
You won't be able to downgrade most likely due to antirollback. That issue your having is common. Only fix is an warranty replacement

Install h90021w this leaves me failing the phone

Hello everyone, I have a LG V10 H900, update it to 6 with LGUPV10 and now it does not let me uninstall applications because it restarts, it does not let any type of blocking since they stop these services, already perform hard reset in repeated occasions and Reinstall the rom and it is not solved.

Install h90021w this leaves me failing the phone
[LG V10 General] hyelton:
Most likely an overall hardware problem. Sadly it's common Could be the battery though. But I'm betting hardware.
[LG V10 General] NIGHTMARE-:
What about uppercut
[LG V10 General] munra48:
My lg V10 says down the stack LG H900 where imei is, where is the QR code says H901.

If I install the rom of 901 could repair the problems I have?
[LG V10 General] hyelton:
You most likely have a referb device. Flashing the H901 firmware will either not be possible due to antirollback and or result in bricked device.
[LG V10 General] munra48:
They will change it for warranty

I'd better not try anything else

[Guide] LG V10 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

I've never seen an LG device officially warrantied by LG that had indications of 2 different models.
[LG V10 General] munra48:
The Ebay seller tells me that he gives me a guarantee

How do they install the rom with 2 different parts?
[LG V10 General] hyelton:
[Guide] LG V10 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

It's common practice. It's not something that's stable. If you bought it on eBay and you see places of 2 different models then it's most likely been repaired in a non warranty way.

If all these issues happened right after you got the phone I'd return it.
[LG V10 General] junejo46726:
Bro i was in the same boat sometime ago

Purchased refurbished v10 labled as h900 on stock 5.1 lollipop

Flashed 6.0 with lgup every thing went okphone boots up normal but security and fingerprint tab gone it force closes

Then i deassembled phone it was vs990 verizon motherboad tempered to show h900 at t

Then i downloaded correct latest firmware of vs990 flashed now its ok working fine
[LG V10 General] hyelton:
I'd honestly return the phone I wouldn't want a Vs990 over a H900
[LG V10 General] junejo46726:
Return not possible

Ok but i bought second hand set from local shop without any warranty.
[LG V10 General] hyelton:
I don't think warranty would be applied as you where sold something that wasnt the actual model you where buying.
[LG V10 General] betoNL:
Thank you for this great thread !

I have been a long time away from forums and I must confess I just read the first page of this thread.

Have been trying to flash a new firmware( H960A) using your guide but I always get the same message during flashing "Connection to server failed" ::

Tried many kdz files, including the latest ( switzerland and europe) always changing language to english ( other country) and always get the same message..

In fact I can only flash a new firmware from TWRP recovery, but the zip file is for the T-Mobile phones so it doesn't work properly on my phone..

Does that mean that I have to flash stock recovery first? I wish I don't have to...or... that someone could upload a flashable zip for the H960A so I can flash it from TWRP recovery

Thanks again
[LG V10 General] sun_is_shinning:
use uppercut, they solve every problem of flashing on this device....
[LG V10 General] betoNL:
Uppercut is fighting with my anti-virus because a supposed trojan...furthermore it is to help LGUP only...

My specific question was about if any of these software will work on phones with custom recovery

Anyway uppercut is fighting too much with the Panda anti-virus so that's a risk I won't take
[LG V10 General] dehwari:
hello guys Im trying to flash Lg v10 h960a with Lgup but getting 0*2000 error and it only goes till 9%.

please help me fix this issue.

Also I think its port problem
[LG V10 General] sun_is_shinning:
uppercut for you too! really, uppercut solve all errors LGUP can give, disable your antivirus first...so it dont mess with it.
[LG V10 General] hyelton:
If uppercut was downloaded from here xda and especially from autoprime it's NOTHING harmful. When you get to using tools like this it's called a false positive.. lg flashtools does the same thing due to there being a web server.

(Your the only person so far I've seen that said there antivirus is flagging it) if you didn't get the file from here we can't help that.

Yes it does work with devices with custom recovery it replaces it back with the stock. Unless you mean using custom recovery to flash these files? Then no.
[LG V10 General] hyelton:
What do you mean by port problem? You are using a USB 2.0 port right? USB will not work. Have you tried using uppercut?
[LG V10 General] hyelton:
[Guide] LG V10 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

That's not an error. [emoji13]. That's supposed to pop up if your using the old method and you drag it out of the way.

But if your running MM you must use LGUP. LG flashtools won't work. And then that would explain the problem if it wasn't flashing underneath that "error" message.
[LG V10 General] dehwari:
I just change com port to 41 then to 3.

which port should I choose?

I thinl the correct port is 16 but when I choose that Lg up shows my device as unknown device.
[LG V10 General] hyelton:
I'm talking about your USB port. Are you using a USB 2.0 or 3.0 port??
[LG V10 General] betoNL:
Thank you for the reactions.

To make a long story short, I flashed from recovery a H901 firmware ( T-Mobile) on my H960A which I bought in Holland. Why? As I said, long story

It works but a couple of things are broken and I don’t care for T-Mobile bloatware and additions

It is Android 5.1.1 so, still LP, so the LG flash tool 2014 should work right?

Furthermore the other tool the LGUP just gives the error:

Like I can’t go from H901 to H960

I wanted to try the TOT method but when you say: 1.1) Download Both Stock Image & DLL File – Download Here , where are the files exactly? There are a bunch of folders in that page

The thing is, I have been reading and trying to research, but there are NOT much to read about the H960A in the XDA, didn’t even find a dedicated custom rom yet…

What the V10 and V20 is concerned, LG is simply ignoring the European market, so, not many of those around Europe, and that's a shame

Anyway , before I try the TOT method, if disable my anti-virus , do you think that the uppercut will do the trick and LGUP will finish the job?
[LG V10 General] dehwari:
Im using usb 2 port sir
[LG V10 General] hyelton:
Try using uppercut
[LG V10 General] hyelton:
You use the tot method if there's a tot file for your model but I don't think there is so that method won't apply to use. It's not going to hurt to try uppercut in your situation but due to the model info thinking it's a T-Mobile model will be difficult to get passed
[LG V10 General] dehwari:
Thanks alot bro i just flashed it successfully with uppercut but its stuck on logo.

what do u suggest for this? A HARD RESET WILL helpfull?
[LG V10 General] hyelton:
[Guide] LG V10 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

One of those cases won't know till you try it, don't remember the button combination though. Should be the same as if you want to enter recovery and just choose yes for reset.

You did flash choosing refurbish right?
[LG V10 General] dehwari:
No I chose upgrade coz with refurbish I got the kdz not support error.

any idea for this error
[LG V10 General] hyelton:
[Guide] LG V10 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

Yeah that problem occurs when you don't flash using refurbish.

Perform a factory reset. If that doesn't work reflash using refurbish
[LG V10 General] dehwari:
Sorry dude I mean when I choose refubrish and click start I got this error

The kdz file not support
[LG V10 General] hyelton:
But what happens when you try and perform a factory reset?
[LG V10 General] betoNL:
Yes, I am stuck...

I just don't understand why there is no way I can flash a stock firmware from scratch like when I was using Odin tool on Samsung devices..

LG sucks a little...

Do you know anybody that could build a flasheable zip so one can flash a firmware from recovery....that would solve my issue I am sure.....
[LG V10 General] dehwari:
I did a factory reset but when I click yes for factory reset it stuck there and stop on yes screen I wait alot but thers no luck

the issue is that I cant flash kdz with refurbish selection.
[LG V10 General] betoNL:
Does anybody got a stock recovery image for the H960A ?

DLL File for V10 ATT H900

Hey I'm unable to find the DLL file for the V10 ATT Model H900

I have looked through the entire Storage Cow site and have looked on Google as well and can't find it. I also have the KDZ file as well as the TOT file so I hear that other tools can be used for the KDZ file if LG Flash Tool isn't working.

All help is appreciated! Thanks!
[LG V10 General] hyelton:
Is there any reason you quoted the entire OP? It adds unnecessary clutter.

There's no dll file as it's not needed. You use LGUP which doesn't require the DLL file. Also make sure your also aware of antirollback. Attempting to downgrade via the old tot method or kdz method and if there's antirollback will kill your device. Using LGUP will at least stop you if there is antirollback.
[LG V10 General] jtl_777:
Fixed. At first LGUP was detecting the phone as Unknown because I had changed the Com port to 41. After changing it back to 9 it recognized it. I tried using the KDZ update method and I'm experiencing the same issue (stuck on LG boot logo). Should I try the KDZ refurbish method or just use the TOT? Thanks!

---------- Post added at 02:38 PM ---------- Previous post was at 02:13 PM ----------

So I just tried both the Refurbish method and Upgrade method with the KDZ. The TOT file I downloaded gave me the Rollback error so I guess I need the latest TOT file. Do you have a link to the latest firmware TOT for the ATT v10 model H900? Thanks
[LG V10 General] hyelton:
Always use refurbish. Never choose upgrade. Sadly no. They'll never be an updated tot it's like this with every LG device that's came out for AT&T. We are very lucky we even got a kdz.

So what's the reason your needing to flash a firmware to start with? You never said. Did your phone start bootlooping or just showing LG logo on its own?

If so that's a hardware failure. Only fix is warranty or board replacement. It's a common issue with the V10.
[LG V10 General] jtl_777:
Ahh... I'm fixing (trying) for someone else so it was just getting stuck on the LG logo. Some times it shows the ATT boot animation. Sometimes I can get it into recovery mode but can't wipe it. It booted up once to the setup screen and shut down again. So are they still covering these under warranty? Thanks for the info.
[LG V10 General] hyelton:
Yes and flashing won't do anything in this cause. It's a common problem. Almost all of them one day will die like this same goes for the G4 as well.
[LG V10 General] jtl_777:
So seems like LG is going to sh*t... I have a samsung and they're pretty solid. I've seen boot looping and hardware issues with a bunch of LG devices in the last few years. LG Nexus included. Add this, the G4, possibly V20 and G5 to the list and I'm like what the hell is LG doing?? Haha
[LG V10 General] hyelton:
G5 and V20 are not on the list of the bootloop issues thankfully. The G5 does have its own set of issues though like bad charger ports. But the G4 in my opinion was the biggest fail of them.
[LG V10 General] betoNL:
I saved my phone !!

The thing is, there is hardly any development I mean custom roms for the H960A...

But there is some development for the H901 ( T-Mobile or something)

To make a long story short I found a custom rom on a Vietnamese (!) forum ( thank you Google translate) which is a kind of H960A port for the H901 :cyclops:

Flashed it from recovery and voilá H960A back....many things like video were still broken but then I could flash one of the latest H960A stock firmwares back ( used Chimera Tool just because it was a free trial still )..

On reboot got stuck on logo, but LG Bridge fixed everything ..

My phone is doing great now , like brand new , just... already rooted and with custom recovery :o

Now , if I buy a new phone , it's because I want to, not because I need too :victory:

Have my mind set on 2 : The LG V20 or the much cheaper but also excellent ZTE Axon 7...

Cheers

The phone is on 5.1.1

ASPL 2015-12-01

Kernel vs. 3.10.49-bcc 1475b

Build LMY47V

Configuration vs B15.LGE.VS990.0

SwVs99011B

Sw status Modified

Ss vs MDF v1.1 Release 5

I am trying to use LGUP to either return to LP stock VS99011B_04_ARB00.kdz

Or upgrade to MM

I enabled USB Debugging, the Device Manager(Win 10) says the VS990 is connected, all of the setup for LGUP to do it's thing, is ready,(? ASFAIK) according to the multiple tutorials that repeat the info here in OP.

LGUP is just "initializing" (underneath the window that says "There is no handset connected") with a sec counter running. The tip says "pull the battery, leave the USB connected, reinsert the battery and let the phone reboot itself"

When I reinsert the battery, it does not reboot itself. It only shows me the battery status.

LG Bridge cannot connect either, I assume because this device was rooted (now unrooted) I just uninstalled LG Bridge.
[LG V10 General] hyelton:
Try putting the phone in download mode?
[LG V10 General] neptun2:
For LGUP you don't need usb debug mode or download mode. Just connect your phone to the pc normally (just like when you copy pictures from it) and start lgup.

I know this, but sometimes like the user above it doesn't work as planned.

Under properties for those "hidden devices" it says "Currently the device is not connected...(Code 45) To fix reconnect device to computer...

Could this be the Driver incompatible with Win 10?

Hi, appreciate your effort to have put up all the guides.

I have a H961N, on 20f Singapore version firmware. Was thinking that if i flash it to HK version I can get to Nougat straightaway without knowing the new anti roll back thing (even if I'm trying to flash it to a later version of android!).

Having to failed that, I tried to flash some older files from 20c (HK) to 10d (HK). These 2 stuck when it shows "system" then pop up the error saying 0x2000, invalid command response (if I remember correctly).

Now can't turn on my V10 (luckily it's not my daily driver now).

Any clue how to bring it back to life? Flashing 20f (SG)? That's my current firmware version.

:D :D Not fun having a dead LG on my table knowing that it's not fully dead because it's still detected correctly.

Can we do a complete reset and flash a fresh firmware?
[LG V10 General] hyelton:
You'll first need to be able to get into download mode to flash any firmware. Does the phone still go into download mode? And what do you see under device manager when plugged in?
[LG V10 General] FutureGamerz:
Resolved. Had to use Uppercut to get it to flash. Need to disable Antivirus though :D But still it won't do refurbish with kdz file. My phone now is neither Sea or HKG. It's just "Global" which means no OTA.
