When will we get the kdz file for the latest update available for AT&T LG V10? The version is H90021X.

Since my device is unlocked and I am not using an AT&T sim card, I don't receive software updates. So I am reliant on your kdz files for updating the device to the latest software version. Do update when you upload the kdz file for H90021X.

Last updated my V10 to H90021w using you steps amd everything went well.
[LG V10 General] hyelton:
Most likely won't be since it's AT&T. ATT normally uses tot files. This phone was an exception once with a kdz file which is rare, which I don't even remember how it was even gotten. Usually with AT&T we get 1 maybe 2 updates and that's it. Rest has to be obtained either by root or OTA update most of the time. You could always get a go phone SIM card. As long as it has an active number on it and your on wifi it will update. You don't even have to have money on the sim for it to work.

Anyone can help me out? I have the VS990 but it's stuck in a boot loop saying:

Boot verification fail

- cause : MISMATCH_SIG_LEN

Trying to use the LGUP to flash it but it's not picking up at all. If I try to go into download mode, the same error appears at the top left of the screen and then it's another boot loop again.
[LG V10 General] NoMurrcy:
how do i get KDZ to work on LGUP it only picks up tot files for me?
[LG V10 General] hyelton:
Choose upgrade, choose kdz then choose referbish
[LG V10 General] modernypraclovek:
I used this guide to go back to stock (Europe 32GB, 10c), but when I check for system upgrade, it says I'm running the newest software. Any ideas if it will come later, or should I install another version?
[LG V10 General] hyelton:
Tried performing a factory reset? Or try using lgs software update software on the computer?
[LG V10 General] ashutosh.chakraborty:
State of phone: On powering on, keeps looping to "Boot verification Fail!!. cause: MISMATCH_SIG_LEN". Need to pull out battery for this to stop. Unable to go into factory reset, since it starts looping before showing anything else on screen. It can successfully go in download mode though, through volume up + usb insert.

How it got in this state: I had TWRP + 6.0.1 custom rom (Andy Zhang's ROM). Felt like going back to stock. Downloaded stock ROM (v10_stock.zip) and flashed it through TWRP. Worked fine for couple of days. Did not like the message on bootup about "Your device software cant be checked for corruption"... So, did "fastboot oem lock". After the reboot, the phone was found in its current state (i.e. looping).

I tried the LGUP method. The LGUP interface shows "H90110c" as Version. However after 9%, I get error code 0x2000 which is "TOT antirollback version is smaller than device version". And then there is no option but to exit.

Can you awesome guys please help me get my phone working? At this time, I do not mind LP or MM or whatever else I can do for it to work.
[LG V10 General] hyelton:
[Guide] LG V10 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

That error your getting is stopping you from destroying your device. As flashing too old of firmware on a us carrier device can result in a compete brick due to antirollback. Any reason your attempting to flash an older version firmware? Have you tried flashing 20e?
[LG V10 General] ashutosh.chakraborty:
Hyelton, I am attempting to flash using LGUP, whatever I could download from the OP links, i.e. H90120e_00_0316.kdz in the hope of resurrecting my phone (since right now, all it does is bootlooping, as described in my post). This is same "20e" that you are asking about?
[LG V10 General] modernypraclovek:
Factory reset after complete reinstall? You sure?

Which software?
[LG V10 General] hyelton:
It's not going to hurt doing a factory reset..

LG PC suite
[LG V10 General] ashutosh.chakraborty:
My problem has been solved. I googled some more, and from somewhere I got a link to a different kdz. Name is H90120j_00_0712.kdz. Flashing it using the LGUP method as given by Hyelton made my device fine and dandy. Thus it appears like flashing H90120e_00_0316 was giving anti rollback error, but H90120j_00_0712 did not give that error. Thanks to Hyelton and other folks for helping out in the process.
[LG V10 General] hyelton:
Glad you got it back. I'll add the newer 20j to the firmware list. You where getting antirollback as you must of had a newer firmware that had a newer antirollback with it.
[LG V10 General] spacekiller67:
Hey guys I am trying to unbrick my F600L (stuck at the firmware update screen) using LGUP but I always have an error at the "system" step.

LGUP always give me the "Invalid command response" error...

I tried with the 20n update and had no anti rollback message btw

So if someone know a fix for this I would be really thankfull !
[LG V10 General] hyelton:
Have you tried using a different firmware? And using a download manager to download it? Also your choosing refurbish correct? And using a USB 2.0 port? USB 3.0 won't work
[LG V10 General] spacekiller67:
I tried with 20e and 20n with same problem at system.

Download manager every time, refurbish and tried both USB2 and 3 with the exact same problem (and 2 different PCs 64 and 32bits)
[LG V10 General] hyelton:
What was the reason for you to need to flash a stock firmware?
[LG V10 General] spacekiller67:
I had issues with the last update 20q and wanted to go back to an older one (still MM) but the flash failed and putted my phone in firmware update mode waiting for a flash
[LG V10 General] hyelton:
Okay making sure it wasn't a hardware failure. If there's a tot try using the old tot method.
[LG V10 General] spacekiller67:
The only tot I was able to download was the 10i to root the system from the Vietnamese Forum.

I can flash it but when the phone reboot it is stuck on the LG logo. Maybe it is an issue with the file but since I can't find anything else...

Do you know where I could find some more tot files ?
[LG V10 General] ruckrider:
i recently purchased a v10 on craigslist its a att version so the H900 but unfortunately since im new to the lg line im kind of lost i did a factory reset but since i did that it activated the FRP and i cant get in to the phone does anyone know if going root will do a total wipe to start from scratch. im kind of lost, can anyone point me in the right direction.
[LG V10 General] hyelton:
You could try this, https://m.youtube.com/watch?v=vEh2VpbNj_c

But if it's running newer firmware like MM which cannot be rooted the next best thing is to hopefully ask who you bought it from if they'll help you.
[LG V10 General] ruckrider:
ive tried multiple bypass attempts but the version im on is already patched to all that is posted or that i could find. being that i contacted them thru the craigslist email they might not respond or even get get an email since the listing is now deleted. guess ill have to wait for the next bypass to be found. got a paper weight for now.
[LG V10 General] hyelton:
If your running MM they're most likely won't be a bypass without having a possible physical box that some more advanced repair phone stores may have.
[LG V10 General] ogonz78:
tried the flashtool method with kdz file but after process is complete it says to contact admin bc server is down
[LG V10 General] hyelton:
Huh? Are you talking about "connection to server error"? That's normal... you drag that out of the way and you'll see it's actually flashing. But if your running MM you have to use LGUP.
[LG V10 General] ExiizZ:
For all who have those Problem with "Invalid command response" start using

Uppercut.exe

https://xdaforums.com/lg-g5/development/uppercut-lgup-loader-g5-variants-t3511295

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

Lgup will only work if your booted into android or in download mode.

So does the phone stay in download mode with the message?

And what did you do prior to Cause this? Looks like this happens when attempting root etc.
[LG V10 General] drix93:
It doesn't stay in download mode, just shows up with the message and keeps restarting.

Well prior to the bootloop/error message, I was using the phone and then it suddenly restarted and was fine for awhile so I didn't take anything of it. Then it restarted again and got stuck in the bootloop, so I factory reset the phone through the stock recovery to see if that would solve the problem but I got the same bootloop result instead.

After that I tried to flash it by using the MM update file through LGUP because at that time I could get it to stay in download mode but sadly it failed and that's how I got the error sigh.
[LG V10 General] hyelton:
Sounds like a hardware failure then if it randomly happened without doing anything. And especially if it was all stock
[LG V10 General] drix93:
That's what am finding out now that it's similar to the bootloop issue that the LG G4 with certain serial numbers face, hardware issue.
[LG V10 General] hyelton:
[Guide] LG V10 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

Yeah the v10 is prone to the failure as well. Sadly they're all great phones but they die :(
[LG V10 General] drix93:
Sigh might just send it to LG to have them repair it if it even makes sense or just move on to a different phone.
[LG V10 General] Horse20102:
i repaired my V10 could the bootloop happen again ?
[LG V10 General] ABN85:
Just something I've noticed the last two times I've restored to stock, am I the only person whose bootloader isn't relocked when flashing a kdz?
[LG V10 General] hyelton:
Flashing the kdz shouldn't relock the bootloader
[LG V10 General] hyelton:
Will never know unless it happens again. Just remember it's a common issue.
[LG V10 General] malilovic:
My LG V10 H900 has 5.1 lolipop and it was working very good till I updated the system to v6.0. The device started getting errors like "LG vpn has stopped" and the menu of finger print scanner is not opening any more, It shows "Unfortunately process has stopped "com.android.setting" and i noticed that it doesn't allow me to uninstall apps. (It results with restart). I did a hard reset but it didn't help, neither flash to stock 6.0. Do you have any suggestions how to solve this problem? Thanks!
[LG V10 General] hyelton:
Sadly if flashing and performing a factory reset then most likely best thing is to warranty it. Your not alone.

while rooting lg v10 vs990 running marshmallow update V23, i bricked the device and now i only it to show Qaulcomm HS-usb QDloader 9008. no display whatso ever. anyway i can fix this? help
[LG V10 General] hyelton:
Only way is a board replacement or try warranty since the V10 is common for needing a board replacement anyway so you may be able to get it warrantied.
[LG V10 General] dannieloco:
Whats the easiest way to restore to factory? I was thinking to do -- 2015 (updated with pictures) TOT Method!

This can be done despite being on the latest ROM OS? I don't mind going back to 5.1.1.

Any ideas?
[LG V10 General] hyelton:
You would use LGUP if running MM or later. You never stated your model. If you have a uscarrier model you most likely won't be able to downgrade.
[LG V10 General] dannieloco:
I have the h901 T-Mobile version and I'm running MM v20L of eliminator's rom.

I'd have to use the LGUP method? and that would take me to 5.1.1?-- wait you said no downgrading is possible?
[LG V10 General] hyelton:
Eliminators rom? Custom rom? Best bet is to flash an stock based rom first based on your model. When flashing back to stock running something that's not can cause issues. No clue on downgrading since it's a carrier model and there's most likely antirollback. Won't no otherwise until you risk it.

And yes lgup can if there's no antirollback.

[LG V10 General] NIGHTMARE-:
H961 is also have anti-rollback ?

[LG V10 General] yogaboy:
Hey!

Can I get that DLL file for H960a?
[LG V10 General] hyelton:
You would need to use LGUP which doesn't require a DLL file
[LG V10 General] yacbos:
is there a way to flash any kdz that is not for ATT for H900 without bricking it ? technically they are the same hardware, am just worried about bootloops or losing the iemei
[LG V10 General] hyelton:
Nope. You'll result in a brick. 1. There's antirollback which will either stop you or go through and trip it which will brick your device. And 2 the modems are physically different.
[LG V10 General] yacbos:
ok i updated to 20w and i cant access the security tab by any mean, i receive a force close com.android.settings has closed

tried reflashing using LGUP to 20w kdz , still the same issue, reset factory default then reflashing, still the same issue.

any idea what can be done ??

phone v10 H900 no root stock recovery
[LG V10 General] hyelton:
Sorry no clue. I think I've heard of this from others and a fix has never been found. Choosing referbish flash correct?
[LG V10 General] yacbos:
yup refurbish while chosing the kdz reflashes but still the same error

tried to flash the rooted h900tot it refuses stating that the file have a version that is older than the current.
[LG V10 General] hyelton:
Yeah prob only fix for it would be to warranty it. I've seen others post about it before.

Yeah cant flash the rooted tot as that would be downgrading and would trip antirollback and brick.
[LG V10 General] RawSlugs:
Help, my h-900 bricked randomly, won't boot. Hard reset fails. Non rooted bootloader locked

Which files do I download seems to be a few options in first post
[LG V10 General] hyelton:
You'd use LGUP and flash the 21w kdz. If there's no antirollback etc with newer firmware. But if your phone was complete 100% stock this is most likely a hardware failure. And it's common. Only fix is warranty.

No sound on a t-mobile LG V10 H901

I have two LG V10, one perfect h960 and one h901 locked to T-mobile, but this sample has no sound. Sound module is "asleep", and it does not detect headphone in and out or anything related to sound, except that sound works like normal through the USB, in and out).

Prior to concludint this is a hardware error and searching a new motherboard, I would like to investigate if there could be some firmware/software error/ block preventing this device to play and record sound through the Android sound system?

Earlier owner got it out of a "stuck on lg logo" problem, perhaps indicative of someone trying to manipulate the software out of lock (device is T-mobile locked).

I have tried the LG Bridge feature called "update error recovery". This downloads approx. 1.9Gb and then updates the firmware. Not helpful, but I suspect that if there is an error in firmware/software, then this recovery is too weak, since it keeps personal information, installed apps. etc.

Hard reset is equally non-helpful

I take it that the KDZ "full wipe" is a complete reset of all information on the phone, iow, if a software error is present, then the "full wipe" will correct that?

I haven't read all 48 pages of this fabulous thread (thanks for the work!), but have others experienced this sound silence?

Any expert would like to comment on doing a full wipe on this particular h901 model (running latest Android 6). Is it normally a safe operation using LGUP + KDZ?

Also, any information about troubleshooting a silent LG V10 will be interesting. Thanks beforehand.

[LG V10 General] hyelton:
INetwork/server error is supposed to show up. You move it out of the way and if everything is correct you would see that it was actually flashing your device. But if you where running MM 6.0 you have to use lgup, LG flashtools won't work.

We don't sell files here.... they're all freely available. Everything is in the OP.

Yesterday bought used LG V10 AT&T

It was stock android 5.1

It has problems in network signals so I downloaded H90021w_00_0921.kdz from storagecow.eu

Flashed it with LGUP every thing done correctly until complete installation phone rebooted normal

After finishing boot when I start phone I get message "unfortunately lg vpn has stopped". Beside that, every time when I try to open some settings like Fingerprints & security I get message "Unfortunately, the process com.android.settings has stopped" and window close.

I tried to reinstall upgrade but same thing

I can not downgrade it with LGUP it gives error

"TOT anti rollback version is smaller than device version"

Also huge confusion

Software say LG V10 H90021w

but hardware motherboard labled as VS990_EAXE50690xxx
[LG V10 General] hyelton:
That would mean you've gotten a Verizon model a VS990. And since flashing a newer firmware that has antirollback you won't be able to change the model firmware back. Only way is to change out the board.

[LG V10 General] hyelton:
Because it will allow you to flash firmware. But your not supposed to. Only have to try to find out what happens. You'd have to use LGUP which most likely will stop you from doing it. Other than trying only option is now board replacement.
[LG V10 General] junejo46726:
Thankks for reply

Sir plz tell

Do i flash vs990 on att labled on its sticker on lcd
[LG V10 General] hyelton:
You do if the board is a a VS990. Meaning the phone you have has been tampered with and or replaced with wrong parts.
[LG V10 General] junejo46726:
Parts means EMMC!!!!
[LG V10 General] hyelton:
Well if the motherboard says VS990 then it would require a VS990 firmware.
[LG V10 General] junejo46726:
Sir plz can you confirm that LGUP CAN FLASH ATT FIRM ON VS9900 without errors phones boots normal works normal as i do with my phone
[LG V10 General] hyelton:
You cant flash AT&T firmware on a VS990. That's a completely different model. You can't flash wrong model firmware.
[LG V10 General] junejo46726:
Motherboard labeled as VS990

I downloaded h900 21w from this thread and flashed using lgup

Everything is working except when i try to open security and fingerprint tab in setting it says com.android.settings has stopped working
[LG V10 General] hyelton:
Like I said earlier , you've most likely gotten a referb or tampered device that's been repaired.

Also that issue is a known issue for the G4 and V10 and even for that replacement has been the only fix for that issue.
