Lg V20 unlock bootloader problem - LG V20 Questions & Answers

I have bought this secondhand handset, he says that it's us996 series, and when i check it in the setting information, it says us996 series, but then i decided to unlock bootloader, we know that us996 series could be unlocked legally, so when i follow the instruction, including put my IMEI and device ID in LG developer website to get permissions, the website says that my handset is LS997, so it can't unlocked legally, could any of you solve this problem? I desperately need your help, thank you (english is not my native language, so sorry for the language)

Sounds like LS997 that was rooted before dirtysanta was patched, and they probably flashed a 996 rom, check ☒ see if you have root. If so it should be unlocked

I've tested it with root checker and it says no, then i checked the bootloader status whether it's unlocked or locked, and it says still locked, it's like no sign that this device had been rooted before

check the sticker under the battery for model number, what does it say? if it is not US996 you can't use LG Dev site to unlock.

WitchKiller said:
Yes it is, does anybody have a solution?

The problem is you got sold a ls997 that got flashed with us996 firmware including the bootloader while it was still possible. The solution is to use it as is, return it, or root it with the dirty Santa method and make sure you use a kernel with the dirty Santa fix (since most kernels/roms labeled just us996 won't have it)

I tried it once root it with dirtysanta, but i got stuck in step1.bat when unlocking bootloader, it didn't go as instructed, specifically in the android terminal emulator section, after we put that long code "applypatch /...../dirtysanta"

You need to roll back to version 10f, grab LG up from this thread, put it in
C:\Program Files (x86)\LG Electronics\LGUP\
Grab the firmware
Put your phone into download mode (power off / hold vol. up / plug in USB cable).
And then use the upgrade option in LG up to downgrade. Then follow the dirty Santa instructions

Probably intentionally removed, its literally impossible to miss. It takes up a large part of the back of the battery compartment (here's my factory unlocked us996 sticker on the original screen assembly). The clean back area is of course the battery compartment. The model being listed as LG-US996 (instead of US996) and the USA on the side (as opposed to BPT or UCL) differentiate the factory unlocked from the other two us996 variants

That's just it: there's no ls997 firmware but it can flash other variant's firmware (except the T-Mobile h918) as long as it hadn't gone past a certain ls997 update (others reading this thread in the future, don't try it, if it's been on Sprint firmware and been updated in the past century it's impossible, think the last Sprint update that could was ZV6 or ZV7 iirc).
Since it's on US996 firmware it should be fine. Also a good idea to use the dump option in LG UP to backup the modem, modemst1 and modemst2, and misc before you reflash with LG UP, basically everything but user data won't hurt.

that was basically all there is to it.
Get LG UP (put it in C:\Program Files (x86)\LG Electronics\LGUP) the firmware (kdz)
Put your phone in download mode by powering off, holding volume up and then connecting to the PC. Open LG UP.
Hit dump option, hit select all, uncheck user data on the partition list, then click ok. Since the phone was originally the LS997 the modem may be wierd so having a known good modem and modemst1 and modemst2 backup (done by that dump) is a good idea.
After the dump actually rollback by selecting the upgrade button and adding the kdz to the bottom section.

Flash a kdz with patch level of december 2016 using same above method. After that root using your preferred rooting method (Mine is given in signature, need to see in desktop mode). Then flash either SuperV20 or Vincent ROM and you should be fine (Let's hope so). I personally like Vincent more because it is based upon UX 6.0, looks nice and have most things ironed out.

I can't, because my variant is ls997, and the variant itself doesn't have .kdz file, i tried it once using LGUP but it says error LS997->US996

Does a thing come up saying it's locked, or do you just not have service? Have you gone through the dirty Santa guide and finished rooting?

LG 20 H910-10Q to US996

My phone is a unlocked at&t h910-10q can I flash US996 Firmware on my phone so I can have a phone that does not have AT&T junk on it using kdz without root
Post a link to the KDZ that you want to flash and I will let you know if it is safe. I can't tell you if it will work, but I can at least let you know if you are going to brick your phone.
If it doesn't work, you will have to root it so that you can flash back to stock since there is no H910 KDZ.
@runningnak3d can I flash this zip https://forum.xda-developers.com/v20/development/rom-us99610k-stock-rom-twrp-flashable-t3691784 on my h910?

Hey @omnixech did you used the us996 kdz?
@runningnak3d any thougs about it?
I got busy on Friday and didn't get a chance to check. I will as soon as I get to work and post the findings.
@prismk @omnixech
The US996 definitely uses the same RSA key as the H910, so you won't brick your phone. I can't tell you if it will work, and I also can't tell you what the ARB version is.
Before you flash, you need to verify from someone that has a US996 what the ARB version is for 10l. If it is greater than 0, then don't do it, because if it doesn't work you will be stuck and can't flash H910 firmware back onto your phone.
Prismk, I understand why omnixech wants to flash the KDZ -- he / she doesn't want to root their phone. You already have root, so what are you hoping to gain?
-- Brian
@runningnak3d I was scared because the us996l zip flash all partitions except recovery, but I will give a try. Thank you!
The US996 ROM have UI differences, like the carrier name (hidden) on status bar and LTE icon. I can change that on H910, but I will have to use xposed and will break magisk
safetynet.
@omnixech If you did used US996 KDZ please update this thread, if it was ok I will use this KDZ too. I won't be able to use an app that my company use because I have root
No I have not used the kdz I most likely will not it is my only phone and do not want to risk ruining it.
I just was tying to remove all the at&t junk on my phone with out have to root, I do not like the current rooting method that is available for my phone leaving that warning message during boot.
I will just leave well enough alone until a better way to root comes along or I get a new phone what ever happens first.
Guys I'm a bit late, but would any of these firmwares work on my H990DS, since I live in the US and don't use the second SIM slot or the FM radio and want the UI changes and the VoLTE

I'm currently on LGH990AT-00-V11k-GLOBAL-COM-JAN-17-2018+0, even though the about phone menu shows V10g-AME-XX (for some reason that I do not know) on my rooted H990DS. If you could please check if this would work in a flash using KDZWriter (keeping boot and the kernel the same?) or flashing the TWRP zip that another user posted, I would be very grateful.

Sorry, the H990 handles the cellular modem quite differently. If it doesn't outright brick it won't have service.. Its why there arnt any Lineage builds for it.
It work for me. Network service working in my country. Except I cant access phone information in *#*#4636#*#*
So I cant lock to specific network. Other than that it runs much smoother without those AT&T bloat.
I did a test on the latest version US99610o_01_0202.kdz and it worked perfectly fine.
Just one note, make sure you are carrier unlocked before flashing to the new KDZ variant.
The only thing I found a little bit of annoying, at least on my case, is that you can't check for updates in the phone, I keep getting the following message "Your phone is not registered yet." Although there is a workaround (just google it), my way of fixing it is by updating through LGMobile Support Tool.
Hope that helps.
So it's possible to flash a us996 rom on H910? I'd like to know because the att ui sucks.

Yes, it is possible, I did the conversion from H910 v10q to US996 v10o.
However I am not sure if further versions in the H910, the ARB is incremented, making impossible to change the firmware, however if that is the case you will be stopped when LG UP will say "anti-rollback check failed" and abort.
In this case I used the patched LG UP: https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222

Regarding the battery, I haven't found any real difference, but the ROM is way cleaner.
The way I did the conversion is doing the following:
Download the latest KDZ variant for US996: https://androidfilehost.com/?fid=673956719939828249
Further versions can be found here: https://lg-firmwares.com/lg-us996-firmwares/
Download the patched LG UP: https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222
Make sure you install it in C:\Program Files (x86)\LG Electronics\LGUP or it will either read the wrong model file (if you had a previous installation of LG UP), or it will not be able to find the model file at all.
Put your phone into download mode (power off / hold vol. up / plug in USB cable)
Open LG UP and click the PARTITION DL radio button, pick the US996 v10o KDZ that you downloaded above, and click start. Make sure all partitions are checked.
Once it is complete, your phone should reboot into the new US996 ROM.

What is your mobile provider? Most likely LTE isn't working since your provider doesn't support the LTE bands from your device.

The above is still true, if this didnt happen immedately after/during rooting/flashing something or using a dd command (while also rooted) your board is dying and you need a new one.

It may or may not work, it works with the G6 and V20, I’m not sure about V35. But it said it might.

Hi just saw your post and I have an AT&T V35 too so this should help:
1. Uninstall any prior version of LGUP currently installed.
2.Head to Post #18 at https://forum.xda-developers.com/android/general/lg-v35-amazon-project-fi-t3819470/page2
3. Download the ' V35_lgup_modded.zip' ; Unzip & install, then ensure the .dll file is also copied to the COMMON folder (C:\Program Files (x86)\LG Electronics\LGUP\model\common)
-If there's no COMMON folder, create one.
4.Shut down the phone completely(phone should also be unplugged), then get into download mode (With phone off,hold down the UP Volume button and connect the phone to your PC while still holding down the UP button) and release the UP button once you see 'Download Mode' on the display.
5.Now, there's no V35 AT&T Kdz file available online so the next best option is to use the Google-Fi kdz you tried earlier; So launch LGUP & select the Kdz file .
6. Next choose the UPGRADE option and flash.
7. Hopefully, that should bring your phone back to life and if not, try again with the REFURBISH option(will wipe user data etc.)
8.Lastly and very important, though you may be tempted to mess around with additional LGUP options such as PARTITION DL etc.; Remember the V35 is still relatively new & has low support so be careful - So far, cross-flashing seems to be fine except for Korean Kdz files but flashing partitions WILL currently cause you to lose either your IMEI/Serial Number or Both.

1. Uninstall any prior version of LGUP currently installed.
2.Head to Post #18 at https://forum.xda-developers.com/android/general/lg-v35-amazon-project-fi-t3819470/page2

Thanks. The guide works good to flash the fi .kdz but unluckly it doesn't unlock the at&t phone (as expected). I made the try. So people if you have an unlocked v35 branded you can go straight with this guide to unbrand it :good:
If someone can help to find a way to sim unlock v35 please give an help. Thanks :highfive:

Just want to be clear on one point. I have an unlocked att version (v350awm) of the phone and have followed steps listed above. i was about to upgrade to the fi kdz but noticed i have two options on the modded LGUP to upgrade, "Fota upgrade" and "Fac upgrade". I was thinking that it should be the Fota upgrade option.?

Hi, just stick to the 2 options at the top left - REFURBISH (For a total wipe, including User Data) or UPGRADE (To update without wiping User Data)

Wanted to thank you to for the info. Am now using the Google Fi rom on my v350awm without a problem. And the beauty of it is, no bloatware.
Again thanks
Google Fi Rom/Kdz
As I posted previously, I successfully restored V350ULM10f_00_NAO_US_OP_0913.kdz to my carrier unlocked V350AWM (AT&T model) using the modded LGUP. Now my thought was that this was the Google Fi rom that comes on the Google version of LG V35. and I know for fact that this rom doesn't have any of the AT&T bloatware that comes on the AT&T LG V35.. When booting I no longer see the AT&T logo, just the LG logo. But the interesting thing is when I check the software version it shows V350AWM10f which seems to say that I really still have the AT&T ROM but the AT&T Bloatware and logo have been stripped out.
Thoughts?

I just got a chance to try this today and it worked awesome. Thank you! Now I have no bloatware on the phone, and managed to get past a Frp bypass. Now I just need at&t to unlock the device and I will be good to go!

True, after flashing, the software version under 'Settings' does not change to reflect the Google Fi update. This is simply a minor labelling error for now but the important thing is that the update is successful as evidenced by the lack of Carrier bloatware/logo. You can actually verify the fact that you are no longer running an AT&T ROM by trying to update via LG Bridge & it should say there's no available AT&T update.

I;m gonna have to agree with you as I just installed the latest (just out) version of the Fi Rom, V350ulm10h which can be found here: lg-firmwares.com/downloads-file/17590/V350ULM10h_00_NAO_US_OP_1130.kdz
After installing, my software version is now showing V350awm10h, again indicating that I still have the AT&T Rom.

Hi Yall,
I'm in this same predicament. I've already disabled most of the AT&T Bloatware .... but I'm still super annoyed at the lack of updates (ATT will only let you get OTA updates if you are on their network, my phone is currently unlocked with an unlocked code and on the T-mobile network)
Are there any other benefits to flashing to the Google Fi version other than debloating? Any chance of VOLTE working? or band 71?
Will the annoying carrier branding on the top of the status bar disappear?

Soft brick

I soft bricked the phone and now can only get into download mode. The phone only has two partitions and I was hoping that flashing a KDZ would fix this.
I'm running Linux Mint on my machine and using SALT an LG type open source program in order to flash.
Question: I heard that I should flash something before the Dec 2017 security patch. I can't find any KDZ files unfortunately and was hoping someone here would have a server I could pull it from.

Oh goodness I'm so terribly sorry I seem to have over looked it.
It's an LGV20 H910
What happened is that I used a ROM that was for another model and it kept crashing. After some time I started tinkering with some other software before I realized that even though I bought the device as a 996 I got the 910 version from the eBay seller.
In any case I remember someone mentioning that if I'm going to flash a stock kernel I should stick to something that was before the DEC 2017 security patch so that I can keep the exploit that enables ROM flashing.
Not sure if that's referring to the bootloader that I'll have to flash or the stock ROM itself.
Oh and lastly I remember someone mentioning that the KDZ for my variant of V20 doesn't have any stock images so I'll have to take one from another model flash it to boot then root it and flash a custom bootloader and then re-flash a custom ROM.
That's probably not how it's suppose to work but it's roughly what I remember.

dear what is the condition of your mobile now? does lg up detect the mobile? if so than use LG UP patched version and try to flash your stock kdz.

Sorry darling that it took so long to reply!
My phone is detected by SALT (the open source program developed by steadfasterX) BUT it is doesn't want to work with LGup on a windows system because I don't have the proper .dll to work with my model type.
The LGup log file says
"LGUP can't load the model."
funny enough though the log file shows the model type right after a hex key string.
It says "LG-US996.. US99610d..."
I can get the phone into download mode but the phone doesn't have any partitions right now. So for now it's a paper weight.

every kdz has dll file, even lg up has dll file. you can extract kdz and get dll for your specific model.
use lg up patched version, search on xda, it will solve your problem.
i can not help on linux and SALT, as i dont have these. if you have access to windows machine, than i can try to sort problem for you.

Help!! Stuck in "No command"

my V35 android 9 shows no command after i try to remove the root with Magisk Manager.
I tried volume down+power and was able to factory reset, but it still shows "no command" after rebooting.
I can't even turn off my phone. It just keep rebooting and showing "no command".
Any idea how to fix it?

See if you can enter download mode
Just plug in the usb and press and hold volume up when the reboots (assuming procedure is the same as v30).
Also download appropriate kdz for your exact variant in the mean time : https://lg-firmwares.com/

If you really have LG V35, do not try to flash any V30 firmware.
Requesting this be moved to V35 forum. (I see it's now been done.)

Why does it have to be the exact variant? I've read that the phone will take any file for the LG V35.
The version for my phone doesn't have one for the USA; and can you explain to me why the files are different sizes? Can they be trusted?

In case that's what he wanted. He's removing root, so maybe he's going to sell the phone or something?
Obviously he won't find AT&T firmware there.

If you can find the kdz for your exact variant then it's good if you can't find then obviously you need to see if other one works.
What my point was on LGv20 it would result in a brick if you flashed h918 firmware on h990
For v30 if you flash h930 kdz on h932 or us998 it won't end well.
But you could flash firmware of a particular variant to another without issues.

Also this question was originally asked in the V30 forum, not the V35 forum. I had a mod move it here, after it was answered by you and me.
As you mentioned, there's one V30 (T-Mobile H932) firmware which will hard brick any other (and vice versa), and there's some V30 firmware you can cross flash to others -- but you lose all telephone capability unless you omit certain partitions.
So you gave the safest answer, considering it was asking the wrong place.
