Understanding the correct KDZ file, help!

Hi,
I purchased the phone in the UK from the network carrier Vodafone. I have done a fair bit of research on the rooting and unrooting process mainly via videos and reading tutorials on XDA.
I would like to root the phone and gain super user access and install some Xposed modules but would also like to be able to unroot and flash back to a stock Vodafone firmware encase I need to claim under warranty. I have been trolling the internet to get the correct KDZ file and found this site (ttp://devtester.ro/projects/lg-firmwares/country.php?country=United+Kingdom). I believe that the correct firmware may be on here but am a little confused on what the suffix and software version means to be honest.
The reason for my confusion is that I updated the firmware to 6.0 Marshmallow through the LG bridge but when I now check my phones software version it states v20b-234-15. I assume this is right but from memory the first software version when I got the phone was something like H81510B_00.
I cant remember exactly what it was before unfortunately but the KDZ files I have found state H81510C_00 (Suffix - AVDFVK) and H81510C_00 (AVDFLR) and this does seem to make sense but I'm thinking it was B instead of C but and not 100% on that.
Do you think these KDZ files would be the correct one to flash back to encase I run in to some problems rooting?
I am also assuming that this KDZ is Android Lollipop and not Marshmallow so is it OK to use this to revert back from Marshmallow?
Thanks and any help would be much appreciated.

The 10X version are all Lollipop, 20X is marshmallow.
When flashing a KDZ on your phone, what's important is what model your phone is. H815 in your case.
If you want to restore to stock in case something goes wrong, you can find everything here: http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
In there is a link to this directory: http://storagecow.eu/index.php?dir=Xda/LG+G4/ where you find pretty much all KDZ files for G4 phones.
I'm not that experienced myself, but I rooted my phone just recently and I can share my experience with you.
I have a H815. It was a V10c-TWN-XX version (Taiwan). I updated to Marshmallow with LG Bridge also and the new software version was V20b-TWN-XX.
Marshmallow rooting is not possible on my phone because I can't unlock the bootloader on it. And Marshmallow rooting is only possible with an unlocked bootloader. Unlocking the bootloader is only possible on European phones (http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryTypeCode=ANRS). I asked autoprime (renown user and developer here) if I can unlock bootloader after flashing an European KDZ on it. He said no, having European software on it is not enough, it has to be a phone manufactured for the european market. Dont know why, guess because of different hardware.
So, not being able to root MM, I had to revert back to stock (downgrade) using one of the KDZs.
I chose the most recent one in the directory I linked (which is the Poland H81510E). In the "Go Back to Stock" thread I linked the OP says to use LG Flash Tool 2014, which unfortunately doesn't work with Marshmallow. But fret not, it works with LG UP! http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
When I tried flashing the KDZ with Flash Tool 2014, the process failed with an error at 5%. It worked flawlessly with LG UP. Here's more information regarding downgrading, but it really isnt hard. Just download + install LG UP. Launch it. Connect your phone. Choose KDZ file. Select option "upgrade". Hit start.
NOTE: after the firmware update was done, the phone rebooted automatically and for me it stuck at at the LG Logo (bootloop). But a simple hard factory reset did it, the phone booted and my new version was 10e-something. With Lollipop 5.1 of course.
After that, I rooted my phone using this pre-rooted image: http://forum.xda-developers.com/g4/development/h815-eu-l-p-t-sea-twn-t3176195
and this guide: http://forum.xda-developers.com/g4/...-tmo-vzw-intl-variants-soon-root-lg-t3164765/
I now have a "H81510e-EUR-XX" Lollipop 5.1 with root (SuperSU 2.49).
I don't really know about Vodafone and if carrier specific firmware is necessary in this case. If not, you could use any 815 firmware.
From the site you have linked with the KDZ files..... it seems they are all the same.
If you check the table for H815 KDZs from Vodafone, there are some 10C and 10D versions. Now I compared the fileKey parameter in the URL to the 10C files and the 10D files and also the bytes of the files.
All the 10C version are identical to each other, same for 10D.
Check out this screenshot I made for you: http://i.imgur.com/Ie0w4us.png
Bytes are also identical, so it's pretty safe to say those are the same files.
Dont know why they are listed several times there. The suffix doesnt matter.
I'd grab a 10D if I were you. But I think the Poland 10E should work, too. Better confirm it with somebody else though.
If you flash your system to 10e, you can use the pre-rooted image I used. Otherwise you will have to inject root yourself: http://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586. In this method you create an image of your system and inject root into the image, which you then flash back on your phone.

Downgrading K428 (T-Mobile) to Root it

There is good information on this forum on how to root your k428 (https://forum.xda-developers.com/lg-k10/development/root-twrp-rom-t-mobile-k428-k10-t3582493)
This however, is not possible on anything later than the 10f(?) firmware, due to there being a December 15, 2016 security update.
Firmwares I am pulling from: https://lg-firmwares.com/lg-k428sg-firmwares/
My K10 is on the most recent update 20h(?), the only thing I've done is unlock the bootloader. I'm trying to get it down to an earlier firmware version to be able to root. I have tried:
Uppercut with LGUP:
There are two separate errors I get with this. One is when I select refurbish and it gets to about 4% (On LGUP, not the phone) and it says my ".kdz does not allow refurbishing" or something along those lines.
I have tried update as well, and I get an error at 14%(on LGUP, 10% on device) and I get "invalid command response code" (image attached)
I have tried both of these options with 3 different .kdz files, so the problems aren't just unique to one file.
LG Flash Tool 2014:
When I start there is an error saying no connection to the server and no progress indicated on the phone or computer, even after maybe 1/2 hour.
After LGUP, I do have to bring my phone back with LG Bridge Update Error Recovery, but interestingly no data is lost at all so clearly my phone is not being wiped at all.
How have people successfully downgraded their k428 and how do I?
Also, is the k428 the same as the k428sg? I can't seem to figure this out and the firmwares website has slightly different specs.
I have another phone, just really hoping to switch to this one is it seems quicker, isn't running Touchwiz, has a decent camera, more storage... I won't be switching if I can't get this rooted because I have been spoiled by rooted devices.

Having very similar issues, at the moment stuck in a "Firmware update" loop with a T-Mobile K10 K428, after trying to downgrade from 7.0 to 6.0.1.
How are you reverting it to useable form with the LG Bridge app?
It only tells me I have the latest update then goes away.
[nevermind, this part worked]
Managed to bring the device back to functional 7.0 state, but have found no way to downgrade back to 6.0.1.. the regret I feel for allowing the update to happen before rooting the device is indescribable in frikkin words.

Hopefully someone somewhere is working on the root of this computer in Android 7.0, I have 3 of these and I need to do the root to unlock them

last Friday I could downgrade a version 10R to 10G and rooted .
but since yesterday I'm with another to downgrade but am getting error while modem part flashing .
version was 20H , I noticed once upon 20 no possible to back In 10 .

i have been trying to make nougat downgrade to marshmallow for months. still no results. most i get is phone simply not booting OS.

SO,there is no way to downgrade from 20g?
what about about using special tools like Octoplus Box andZ3X Box?
anyone tried?

My apologies if I misunderstood. Is this a way to apply alternative ROMs even on models with locked bootloaders and the ADB Commands stripped out such as the H 933? I know you said already that it will work on any variant but I had lost hope that this model would ever allow modding of the rum. I just want to make sure I'm not misunderstanding the intention of your guide.

Nothing custom. Everything needs to be RSA signed by LG.

Oh well, wishful thinking amd my mistake. I read it as upgrade or downgrade (eg various images) or restore stock.

Out of interest, will this work on a rooted V30. I seem to struggle to get LGUP to boot my phone into download mode. Is it because I have twrp as recovery?

It will work as long as your /laf partition is in tact. It containts the DL mode. It has nothing to do with /recovery partition where you most likely flashed TWRP.

Just so I don't brick my device, I have an H930DS, therefore any firmware marked for this model (https://lg-firmwares.com/lg-h930ds-firmwares/), regardless of region, would work on my phone? My phone is currently on HK region version, can I flash the Indian firmware for the same model?

I have no idea about cross region firmware flashing. I have not found any official documentation about how each of LG UP's functions exactly works, it's all user experience here on XDA. Supposedly, every region has firmware signed with different RSA key which is verified upon trying to flash and it will reject you if it's a mismatch. Also I doubt Indian region has the same bands as HK so you might cripple your mobile signal if you happen to be on a band that is not supported in Indian firmware. Personally I don't recommend trying it but its up to you Please share your experience if you do
I know for sure that all H930 sold in EU, regardless of what carrier can be flashed with the same H930 unbranded EU firmware, which removes all carrier bloat and branding.

@sasc Check the RSA signature of your firmware and compare it to the firmware you want to flash. If they match, then it won't brick your phone. Your phone may not work, but at least your will have access to DL mode. If they don't match, you will definitely brick your phone..

India and HK are both global GSM regions. The bands are the same, just like Europe.

Could you please tell us what's the best way to check the signatures?

Okay.. I bring good news! You can definitely flash any KDZ as long as the model number is exactly the same. I flashed the HK Reginal kdz on my H930DS from India and I now have working VoLTE and VoWiFi.
In short, get the CORRECT kdz of the desired region for your model number, use LGUP, Upgrade option, and let it do its thing. Simple. This keeps the device official and under warranty.
PS - Please backup all data before doing this. Even though it is just an upgrade, play it safe. Just in case!

Thats great news ?. One question - to get VoWifi working, person at the other end should also have VoWifi? Or we can call VoWifi to VoLte. I have never tried VoWifi so just curious to know.

So...kind of didn't work.
I used the H930DS marked India in lgfirmwares. The flashing process went fine, except for the phone getting stuck right after the last restart and the screen went blank. Waited a couple of mins and forced a restart using the power button..booted fine but all data was gone. Thankfully i did backup some stuff, but not all..
Checked the Software version, it says V11i-GLOBAL-COM, which is obviously not the India version. And, I still dont have Volte!! So, this was futile..
Can anyone point me to a certified H930DS India KDZ?

Has anyone been able to get fastboot access on the G710VM with Android 9.0?

So, I picked up a used G710VM 64GB Storage/4GB RAM, I specifically wanted this model because I'm on Verizon and wanted to ensure that my phone would work with their wack-as-all-hell network. Upon booting it up on the stock firmware for the first time, and intentionally not putting in my SIM, nor getting it online, I saw it using up 16 GBs of storage right out of the gate, and about 2.8 or so GBs of RAM. I thought this unacceptable, and so began my journey of putting custom ROM on it.
I was looking at putting either Lineage OS or AOSP, but both guides require getting TWRP on there first, and that has been my hang-up.
I followed this guide on getting the bootloader unlocked, and got that done.
Now my problem is fastboot mode, with the bootloader unlocked, and on the G710ULM11g firmware, I can get into it just fine. But on the G710EM20b, G710EM20d, and G710ULM20d firmwares I follow the steps to get into fastboot mode, get a warning about the bootloader being unlocked, and then it just does a proper boot up into the OS, every. single. time. And I've gone back and forth between my 8.0 and 9.0 versions of Android a few times, and confirmed it's only the 9.0 ones that are giving me this issue, the 8.0 one lets me in without fail.
Did I unlock the bootloader wrong? Or am I just using the wrong firmware? Has anyone else had luck with a G710VM version of the phone? Or did I hose myself by not buying a ULM or EM version?

Out of appreciation for all the work that everyone in this community does (I read lots but don't post often) I would say, you need to search and skim through at least an hour worth of posts to find that answer, but I'll link it here to say thanks. Short answer- PIE loses Fastboot commands. You can flash to Oreo, and then you should be able to use fastboot commands. I still haven't found a posted method for installing TWRP. I just acquired an 'unlocked' Sprint model with the ULM firmware and would love to explore rom options.
https://forum.xda-developers.com/lg-g7-thinq/how-to/cross-flash-oreo-pie-firmwares-lg-g7-g7-t3915303

In the same guide post if you look on page 6 you will find how people have updated to pie retaining fastboot.
It can also be used to use a pie vm rooted stock rom also.

Thank you very much for responding.
And that really sucks about fastboot and Pie, now I have to wonder how LameMonster82 did it in his guide . Someone else there tried installing that TWRP from Oreo, and got his phone bricked for it.

Weird, I'm using G710EM20d firmware on my G710ULM and it boots to fastboot.

"Weird, I'm using G710EM20d firmware on my G710ULM and it boots to fastboot."

I'd really appreciate the help

Verizon V30 VS99630d update pushed out

I haven't been around much in some time but figured I'd mention I woke to a update message on my phone. Going to push it if as long as I can, that is assuming there is still development going on.
I'll try to see if I can find a location to DL the image to provide it to whoever might be able to tell me if it's okay to apply to my tired phone.

This is probably OTA and full KDZ will be released soon. You can capture KDZ with LG Bridge URL.

In the mean time, how do I stop big brother Verizon from bugging me to update the firmware. My phone is rooted with Magisk so I can't take OTA.

Use Titanium Backup to Freeze:
System updates 2_18_06_0
System updates 1_15_10_0
And possibly:
Software Update 9

Just freezing the 2 System Updates will do it.

I have to say I'm very impressed! Like it's been 3 years since the V30 launched, right? I had started at replacing this phone due to the lack of security updates, but now I can keep using it a while longer, awesome!

I am currently on the debloated vs99630c rom. Can the Verizon updated rom be downloaded onto the phone without losing root?
Do we know if anyone is trying to make this into a twrp installable rom, hope so?

Never used LG Bridge and saw a procedure you were trying out several years back: https://forum.xda-developers.com/lg-v30/help/us998-kdz-file-request-t3726918/page2
Couple questions:
1) Does the procedure for downloading the KDZ "mess" with your existing recovery / system partitions? (I'd like to try and get the KDZ but not at the expense of needing to worry about restoring things back to the way they are now.)
2) You seemed to have trouble extracting the URL at first, then had success later on. What was the trick to getting it to work?
Thanks,
Drew
EDIT: LG Bridge doesn't connect to my V30 VS996 for some reason. Have tried within TWRP and the LG Pie ROM. Have tried File Transfer mode, Charging mode, System Update mode, etc. Within File Transfer mode, the software appears to try to connect, then fails and suggests I disconnect/reconnect the cable which I do to no avail. Oh well, I tried.

You need TWRP flashable zip. The full KDZ has not been publicly released yet. JohnFawkes or Seadersn would have to make it, when the KDZ is released

You can look in the Bridge's download log file and find the URL that was used to download the .kdz
The link can then be downloaded by anyone using web browser. Sometimes User-Agent change is required, I think to "spider". I used a chrome extension to temporarily change the user agent so the LG Bridge server didn't see I was using a regular web browser.

Any chance that someone with a VS996 and LG Bridge that works can PLEASE check to see if the vs99630d KDZ is available for download?
I would, but I've tried using LG Bridge with multiple PCs and cannot get it to connect to my VS996. It shows the Connecting... screen but just times out regardless of what I do.
Thanks!
Drew

I will try
edit: LG Bridge is not working for me either. However I just googled and there is a 30d kdz on https://lg-firmwares.com/lg-vs996-firmwares/

Thanks for confirming I'm not the only one with LG Bridge issues and for finding the 30d KDZ!
Direct link to 30d KDZ page: https://lg-firmwares.com/downloads-file/23387/VS99630d_02_0821_ARB00
Now the next question is -- is @JohnFawkes still on the scene and able to work the same magic he used for the 30c TWRP zip with the 30d version? My guess is this is the last time Verizon/LG pushes out an update for the almost 3 year old phone.
Thank you!!

There is a tool to convert .kdz to twrp .zip. But it says it only works for old kdz. I dont know how the new KDZ are converted.
https://forum.xda-developers.com/tm...-kdzz-create-flashable-zip-kdz-files-t3902423
I think though you can update with the kdz using patched LGUP via REFURBISH or PARTITION DL. You will lose twrp, but you can reinstall twrp afterwards. Then I think you have to install magisk again, as well as Disable_Dm-Verity_ForceEncrypt_08.18.2019 (encryption disabler) and AnyKernel 3 RCTD Remover (root checker disabler). All that is explained in this link.
https://forum.xda-developers.com/lg-v30/how-to/wtf-lg-v30-t3790500/post79972584#post79972584
Also I think you lose data, so have to backup apps and stuff if needed.
I might do this in the next time. I dont know if there will be a flashable twrp zip.

Was just looking into KDZZ and yeah I think John figured out a way with new KDZs (or else we wouldn't have one for 30c). I recall it taking a few tries with us beta testers so it's evidently not super simple. If John is still around, hopefully he can share a how-to on this new KDZ, or just create the TWRP zip for 30d himself...
Not sure about your 2nd idea because that method seems to require fastboot commands which the Verizon firmware doesn't allow. I could be wrong here, but I'd hold off doing any of this until someone confirms one way or the other...

Thanks. I'll update the VS996 Pie KDZ thread tonight when I get home.
@JohnFawkes.

Nah I won't be updating anything. If you guys aren't aware, I don't do android development anymore. Please refer to this post as to why
https://twitter.com/topjohnwu/status/1304871604833329153?s=20
Sorry. If I was still doing development I would make it but after everything with fontchanger and all the bull**** I put up with, I can't force myself to do anything dev related anymore
---------- Post added at 09:29 PM ---------- Previous post was at 09:09 PM ----------
I'm sure @seadersn would do it if he has time though

the developer is fed up with the constant harassment (even death threats) from other "devs"

good point, if fastboot commands dont work on 30d

Honestly you can just flash the kdz and select everything except recovery to keep twrp

@ChazzMatt
Since you are the guru for all things V30, have you already made a guide for how to flash a KDZ in LGUP and keep TWRP?
My Download Mode has been borked since Oreo on the VS996, so do you think flashing the US998 20e TWRP zip will fix that issue AND should I expect any problems flashing an Oreo US998 rom after being on a Pie VS996 rom?
I am guessing if I somehow regain Download Mode with this 20e method, then I use LGUP's Partition DL mode and check everything but Recovery for the 30d KDZ?
Then what else would we want to do before booting into the ROM in terms of encryption and all that John normally includes in his TWRP zip?
If anyone successfully completes this task of keeping TWRP and Root with 30d, can you please report back?
Thanks!
Drew

We tried that in the early days -- before Westwood24, JohnFawkes, and Seadrsn. It was hit or miss, and turned to mostly miss. Theoretically, using Partition DL but omitting the recovery partitions, it should cleanly only update the those partitions and leave TWRP intact. But for whatever reasons, that would often not work. (I can't remember whether it just bootlooped or got hung on logo. Been a couple of years ago. It would be discussed early in the Oreo KDZ threads.)
After attempting that, many people then had to reformat their phones, flash the full KDZ (either Refurbish or Partition DL) and then reinstall TWRP again. Bootloader was still unlocked, of course, but they had to go through Section 6 of WTF Instructions to reinstall TWRP over the updated KDZ. If you have H930 variant or US998 firmware, that's NOT a deal breaker as those have fastboot flash commands. But for Verizon firmware, you can't do that.
This is why the TWRP-flashable zips (basically stock ROMs) were such a godsend. You kept your data and kept TWRP.
