Correct KDZ File for Root Help - H990DS - LG V20 Questions & Answers

Hi all,
I recently purchased a brand new, factory sealed, LG-H990DS from Amazon.com in the US. From all the documents that came with it, the unit is from LGE Singapore. However, my firmware is v10f_SEA_XX rather than an SG version (I understand Singapore versions should be _SG, correct?).
Now, I want to downgrade to an earlier security patch (Currently June 1st, 2017), so that I can root the phone and hopefully enable VoLTE (I have it in Quick Settings but it's grayed out and I can't toggle it )
I'm confused about which .kdz to use... there's a bunch of SG and TWN ones, but won't that brick my phone? I already bricked my first H918 (T-Mobile) one by somehow flashing the wrong T-Mo .kdz (in hind-sight I should have checked the md5 sum). I know H990DS is a lot harder to root than TMO so I'm kinda scared. I've rooted/flashed on many, many phones, but the H990DS seems to be the most tricky.
Thanks for your help in advance!

I've got H990DS too and managed to root it.
I am using this guide https://forum.xda-developers.com/v20/development/dirtysanta-h990-t3624296/.
But I've got November 2017 security patch, so I got to downgrade to earlier firmware using this guide https://forum.xda-developers.com/v20/how-to/restore-v20-to-100-stock-bricked-devices-t3524903. I use oldest firmware available, that is v10b https://lg-firmwares.com/download-file/?fileId=4345. and currently stuck here with 10b. currently figuring out how to update to the latest firmware using KdzFlasher

Hi Boxy52, I have the same phone, the KDZ file you need is (https://lg-firmwares.com/download-file/?fileId=5196) version "V10c", with this you can begin the tutorial writed of the described above by the damadikaz, after you can upgrade the firmware up to version V10h on tutorial https://forum.xda-developers.com/v20/development/tool-kdz-writer-t3649818...

Hey damadikaz,
So to confirm - it doesn't matter which region I flash - I won't be bricked, correct? My only concern was if I flashed the wrong region. But if all H990DS firmwares work with eachother, I shouldn't have an issue other than bloat?
Thanks!
boxy52

Hey pkrename,
You have the SEA firmware as well right, so I've got a question - do you have any bloat ware? Mine has none! My phone shipped with V10f_SEA_XX and I have ZERO bloatware its amazing because I've heard everyone else with SEA firmwares was stuck with a lot of bloatware. Do you think I've got some special version of the ROM? Just want to make sure that I'm indeed on the same ROM as you.
Thanks!
boxy52

Hi Box, Sorry I'm late, about the firmware bloatwares, I have no problem with them ... at least in my firmware I do not have many bloatwares other than google.

For anyone wondering:
First try the TWN series of Firmware. My phone came with TWN-10C (December 1st Security Patch) so I was able to root straight out of the box. I still use the TWN firmware today (except the latest version as displayed in my signature) as this is the cleanest of Firmwares I've found so far. All I had to do was use Root Uninstaller to uninstall a few Facebook/Instagram/other apps that came with the firmware and that was it.
Secondly, the SEA/SG (South-East Asia and Singapore) firmwares are the same, as seen here
Hope this helped

Wanting to root H990DS -- Which firmware should I use?

Hey all,
So I'm shortly about to receive my V20 H990DS. I've read that in order for DirtyCow to work, I need to have a firmware with a security patch prior to January 2017. I'm in Australia if it matters, but I'm wanting to know which firmware I should use, if there's any difference between them at all apart from versions. Once I'm rooted and Unlocked with DirtyCow on it, I understand I can't update the firmware or anything (unless I'm wrong?), so I'm wanting preferably the most stable firmware if possible as this will be my daily driver, and I will be running it stock rooted.
Cheers

Looking for comprehensive stock firmware list for S7Edge

Hey all. I am in the US but bought international S7Edge when it came out. I dont know what firmware it had I think it was some italian one maybe. Then i rooted and started using custom roms. Then when nougat officially came out for S7Edge i un-rooted and went back to 100% stock using i think Vodafone 7.0 firmware. I think because i rooted i have a negative test response from Knox which i think stops me from getting OTA updates. It shows in software info that my OS version has security patch only from January 2017 so I am clearly not on latest firmware even though OTA says I am on latest.
Is there a site with a database of all firmwares out for the S7Edge international variant So i can find the latest and flash it to my phone since OTA wont get the latest.
samsmobile has the latest.
Yoiu still have an issue with your kernal as phone still thinks you have custom rom. Tripped knox on stock firmware will not stop OTA from downloading.

Looks like you've the att model, are you actually on ATT? I've seen reports that if the att model doesnt have an ATT sim it wont find updates.

Well it seems so. I tried rooting it with kingoroot and it failed. Then i searched online for rooting solution and came to know that v20 cannot be rooted by these software because the bootloader is locked.. It needs another method (told in forums). Well i didn't try them.
I need some further help in this regards. I have few questions. I hope you can answer them.
1. If i unlock the bootloader and install twrp and then install the stock rom, CAN I INSTALL ANY stock rom, for example, stock rom of international model instead of at&t version?
2. I am using h910 but not with at&t sim. I am on other network. Will installing with official rom (other than at&t version), keep the gsm working>?

You could possibly flash the US996 which is the unlocked version, as far as updates you'll have to check and see if there's updates for it from LG, but the big concern would be determining what bands are available with that variant to see if they are compatible with your carrier, you can also check this forum and see if there's updated 996 roms that you could flash to get the latest security patches. But as the previous poster stated as long as you are on 910 rom and using another carrier's sim you'll never get an update from AT&T

I want to flash back to ls993 firmware after flashing the H873 oreo kdz

Hello everyone, I just got this G6 ls993 with stock firmware Nougat on 29th May.
Then I went through some of the thread and found there is the way to flash different stock kdz to change the model.
And as you know that H873 has released its oreo stock kdz weeks ago, can't wait another day to use the new oreo system.
So I downloaded H873 stock oreo firmware and force flash the h873 kdz to my ls993. So far everything works well.
And of course, my phone model was change from ls993 to H873 with the new oreo firmware as well, then I just realized LG has released its official oreo for ls993 on 31st May...
I regret why I couldn't wait on the Nougat for 1 or 2 more days,otherwise I would be able to just ota to oreo as a "ls993" rather than "H873".
Now the question comes, is there any chance that I can flash ls993's stock Nougat or oreo?
I've been searching for the ls993 stock kdz for a while , but seems LG hasn't released any version of stock kdz for lsd993 yet and not sure if they were already on the way to do this either.
There may be probably no official stock kdz for ls993 , so what should we do to flash back to its stock model?
Hope anyone who is suffering the same problem can help to get it solved.

So, obviously, you are pretty much scr3wed right now. Flashing different model's .kdz was HIGHLY unrecommended.
First of all, you can try repairing software using LG Bridge on your PC. I don't know how this works but that piece of crap reflashed my phone with branded carrier software that was originally installed on my phone and I had totally different firmware flashed... it still managed to recognize my device and punish me for debranding my device.
So try this in the first place, LS993 firmwares weren't released by LG as stated here down in the comment section.

Hi a guy posted the below images from ZV6 but dont know how to use it and dont know if it can help you, I dont need it cause dont live in the US and wanted to sim unlock my phone.
https://mega.nz/#!mUMGXQrT!si9ED-X5_yOq1P21Xz9vKMT_uC3N7dcEyRgIWobHh-Y
I posted a thread on LS993 asking if someone could make what the guide say and try to save the KDZ from a ZVA version ,but no one has replied. And when I found that guide already flashed my phone to H873.
Its a shame that people dont wanna help

Thanks for the advise, seems the only way is to wait for LG to release the stock kdz for ls993.
Anyway hope it will come some day...

I don't think they don't wanna help.
All ls993 users are in the same situation,
1. There is no kdz for ls993, so no one can do a fresh restore to the stock firmware.
2. No root or TWRP, there is no simple way to restore the system.img to ls993
Let wait for LG to release the kdz for ls993...

I have some new findings at https://www.needrom.com/download/ls993-7-0-tot/
As shown in the page, it is a LS993 tot file, however, seems current instruction only work on kdz file and there is no instruction for tot.
I know that tot file is also an img file with all the system partitions, it was used for flashing the stock firmware as well as kdz file.
I've successfully downloaded the file from mega and its size is about 6G after extracting it from the zip file.
So looking forward if anyone is familiar with tot file flash and seems this should be the possible way that we can flash back to ls993.
Thanks.

Please Help for me.How to force flash H870 firmware in Ls993
How I force flash H870 firmware in LS993 help me Now.
I am in the same boat. I ordered my phone on Amazon used because it was selling cheap. Curious i wanted to see what the modding community was doing for this phone so i looked into the phone itself. I checked to imei and it said my H873 was actually an LS993. It is running the H873 Oreo rom H87320c rom. Can i do the i update or am i screwed for now?
I bought one of the Amazon AS993 phones as well (was labelled H872 on site). Will H872 kdz flash successfully on this and give me the Volte calling with Metro/T-Mobile? I have the phone online with metro now but the firmware is set up for Brightpoint network without Volte calling and native video calling. I do understand the imei will conflict with OTA updates, but will H872 flash and work like it should on this hardware - all components appear the same.

Hey guys, One of my friends S7 edge(SM-G935FD)duos unlocked bought in Australia, Probably a grey import is stuck on MM without any updates

I been reading that it could be updated through Odin. Just trying to get it updated to Oreo!
Just few questions before i proceed
1. Can Oreo be flashed directly on MM without going to Nougat?
2. Since he is using the phone in Australia can i flash SM-G935F firmware's found on this link? https://www.sammobile.com/firmwares/galaxy-s7-edge/SM-G935F/XSA/
(just hoping he would get future OTA updates if i flash Australian Firmware. right?)
3. From the above link, how important is the CSC & PDA , can i just choose the latest and flash? Unlocked phone
4. any tips or guides you guys can point me towards
Thank you
sorry, anyone able answer my 1st question if possible?
