Crossflashing LG H870DS - LG G6 Questions and Answers

Is it possible to flash another firmware, let's say of the European model H870 and get it working or at least be able to rollback to the original firmware if it doesn't?
EDIT:Tried and I successfully flashed the H870 rom on my H870DS, although it's not anywhere close to usable. I was able to go back to my original rom without any problems whatsoever (using uppercut + lg up). Anyway my aim was to try and unlock the bootloader through this method. It seems that it only works on Oreo for the V30, hopefully will work on an Oreo unlocked rom for the G6. I'll try as soon as a KDZ is available.

Only DS Firmwares, if you really have DS. The DS was not officially released in Europe, so you dont get an european customised Version.
Use Uppercut and LGUP and download a firmware from lg-firmwares.com . This topic was communicated alot in this Forum, just use the "Search" Function.

I have the H870DS, someone recently unlocked the bootloader on a V30 by crossflashing to a rom of an unlocked V30, which bricked the phone but he was able to flash an unlock.bin file through fastboot commands which he created just by typing some 1's on a txt file and saving it as bin. The whole affair is a bit bat**** but other people succeeded with the method.
So that's why I asked, I want to flash the rom of an unlocked G6 and try the same thing.

You're very much on your own with that! Don't just assume because someone else has managed to somehow cross port/flash something... That it automatically means you can try something similar! If you brick your phone... You're on your own!..

Yeah I know it's very possible I will brick my phone. The whole process is a bit farfetched but still I want to try if it means I can unlock it.

I'd encourage someone who doesn't know what he/she is doing to ask for help, but that's me.
Thanks anyway.

Once we get an unlocked kdz we will have what we need to test. At this point we need a T mobile oreo kdz or an unlocked.

V20 H990 Single SIM

H990DS Dual SIM
Im not sure in near future
The V10 dual sim (H962) did get root, but to my knowledge, the bootloader never got unlocked. It'll probably be the same situation for the V20.

Seems like not root for us.
The thread does not include the h990.
Bummer.....

Take a look at the message right above, on that thread notice this message.
The more interesting question at this point is bootloader unlock. Given how generalized the Dirty Santa technique is, I'm pretty sure unlocking the H990DS bootloader is merely a matter of a little bit of time.
The lack of a bootloader unlock for the H990 so far is the reason I haven't got one.
The US996 is missing three bands that are used where I live (band 1, 28 and 40). But if the bands can be unlocked I'd consider getting one.

H990TR ?
Kardeş uzun süredir takip ediyorum bir hareket göremedim TR yi gören cevap vermiyor zaten @ahmetoguz8
Guess it is past time to add a mention on this thread (in case anyone subscribed and didn't notice other threads). Took a while, but root is available for the H990. The major limitation is it requires a publicly known KDZ which is old enough to allow DirtyCOW to inject the unlocked bootloader. H990DS and H990N have been shown to work, though the root isn't 100% stable (there are miscellaneous reports of difficulties and the procedure is complex). This includes bootloader unlock, so you can do pretty much anything you want.
The oldest H990TR KDZ is January 10, which is a few weeks too late. Someone might try it, but I'd give poor odds of success. I'd give good odds if a 10a-10d was known, but no one has pointed towards one.

Yes. The method is quite complex, but does work. There are a few reports of camera difficulty, but most people appear not to have any problems other than the instructions being complex.

I have successfully rooted and everything works except voLTE. So i am trying to flash another Indian firmware via LGUP. So do i need to follow the "Going back to stock:" instruction from the rooting thread ? Or should just flash the firmware via LGUP ?
Copying my question from the n00b thread.
Hi Guys,
I recently got a H990 DS and I'm loving it. I was wondering if root is possible for it? The Android patch level states June 1, 2017 and the build is NRD90M.
Thanks!

And funny enough, you look at the source of the information and an answer is readily available. That build can't be dealt with, but for most H990 devices earlier KDZ files are available, so downgrading the image allows the root process to proceed. Afterwords getting back to a current image isn't yet a science, but is doable.

LG G6 Using different KDZ's

I'm new to the LG Ecosystem and I have a few questions.
I have an LG G6 H870 from Entel in Chile, its currently on Android 7.
1) Can I flash it to something like the OPEN EU images which are newer?
Because they're all H870's are they the exact same hardware, meaning the functionality on different H870 kdzs should work fine? The Entel doesnt even have a 2018 release yet so I don't have great confidence they will update the LG G6.
2) Does flashing a KDZ affect the boot loader?
If I unlocked the bootloader for rooting would flashing the KDZ back reset it back to locked?
3) Is it safe to flash a KDZ via a virtual machine? The LG Bridge app wont detect my phone on Mac no matter what I try (High Sierra), (adb is fine iv tried the drivers etc), however it shows up when I connect it to a Windows 7 VM.
4) Is it likely that when the official Oreo 8.1 update comes it would be better to switch to something like an OPEN EU or UK image?
Or even just flash the new 8.1 KDZ when its available?
5) If I rooted and flashed something like LineageOS, can I easily go back to any of the KDZs with the LG tool?
I noticed theres an "error link which seems to download a KDZ for resetting your phone. Does that work off some kind of internal hardware serial, meaning that if things are ever soft-bricked I could just hit that button and go back to square one no problems?
6) Anything else I should be aware of or concerned about if I want to play with flashing different KDZs or custom roms? I dont care about warranty e.g. unlocked bootloader.
7) Whats the best tool for unlocking bootloader and gaining root these days, I know theres a tonne of AIO tools and things like KingRoot. Any suggestions from other LG G6 modders?

1) If it's just an "H870" than yes, it should be fine.
2) You cannot unlock the bootloader. Only unbranded US997 and European H870 can.
3) Never tried, it should, but in this i cannot give you a certain answer.
4) 8.1? We don't know it'll be 8.1. Anyway it's always better to flash the right firmware for your region.
5) You cannot do any kind of modding on your device atm, see the 2nd answer.
6) Flashing a wrong kdz could hard brick your device, so be careful on names. For the warranty you're good to go, you cannot do any kind of modding.
7) For G6 there is no "best" tool, there is only ONE way to unlock the bootloader but it won't work on your model (as explained in the 2nd answer), other tools like KingRoot don't work at all.
Bonus answer: No, flashing an european firmware won't allow you to unlock the bootloader.
Sorry for the noob question, it's probably been asked on here, but have not been able to find a solid answer. I have a US Cellular LG G6, which by now I know bootloader can't be unlocked. But, is there any way to update to Android Oreo? Currently on Android Nougat 7.0. thanks in advance.

I have found out the hard way that there are several versions of the model US997 variant of the LG G6:
https: //lg-firmwares.c o m/lg-us997-firmwares/firmwares/
(I apologize that the forum's spam filters are preventing me from posting a working link. Just take out the spaces.)
There is a USA unlocked version, two US cellular versions, two "Brightpoint" versions (whatever that is), and an Amazon version. And they all share the same model number. This is quite confusing because with most phones, usually there is only one version per model number. If your phone is stuck on Android Nougat, chances are you're like me and you're on the USA unlocked version of this phone, not the US Cellular version. The US Cellular and Brightspot versions have all been updated to Oreo and the latest update was in September 2018.
I have no idea why LG isn't upgrading the USA unlocked version. It was very frustrating when I bought it used and found out it was still stuck on Nougat, which I was not expecting.

Actually the US Unlocked version has gotten the update and it's bootloader unlockable... My phone is the US997Z which is the US Cellular version. I believe you have to be connected to their service to be able to receive the update through their towers. I went ahead a upgraded my LG G6 with the US unlocked version kdz as the @HueyT mentions above. Update went great using LG up and uppercut no set back going through the update. If you need help I would happily help you out. Because I was in the same boat as you.

It's very strange that some versions of the LG G6 "US997" are not updated to Oreo yet and other ones with this version are. But if there is anyone out there reading this, you know know there is a workaround and you can force your computer to update the firmware on your LG G6 with the official LG ROM that runs Android Oreo.
For the $254 I paid for this phone used, with a case and the original charger, I can live with a phone that I have to update manually if I won't get OTA updates for some reason. And I did not break the phone's security because I'm still able to use Google Pay and online banking.

[LG G6] Trying to unlock the bootloader unofficialy

Sup guys,
Think it is my first post related to the LG G6. I have worked on LG L7II and LG G4 before.
Just having a little time on my hands. I have an LG H870DS and as you know LG does not support unlock.
I would like someone to provide me the following if you can (from an international H870).
DO NOT POST THE INFO HERE SINCE I WILL ASK DEVICE SPECIFIC NUMBERS.
This request is for someone that wants to unlock via LG Dev but did not unlock yet.
Please provide me with the following:
Copy with LGUP patched version of partitions (BEFORE UNLOCKING):
1. /cust
2./persistent
3./drm
IMEI, DEVICE ID from fastboot, unlock.bin
Copy with LGUP patched version of partitions (AFTER UNLOCKING):
1. /cust
2./persistent
3./drm
Ty.

Also, just unlock.bin device-id and imei will help even if you are already unlocked.

I dont understand your request clearly. You wrote that this request is for somebody who did not unlock his phone yet. But who did not unlock it he most probably dont have the unlock bin. (I cant imagine somebody got the unlock bin and left his phone locked).
So you need cooperation with members who got their phone unlocked and can provide you with the required data or you need somebody who can experiment with his phone?
By the way i have an LG G6 still locked.

there was a misunderstanding in interpretation, i meant that if once i have the unlock files i dont keep my phone locked but start immediately unlocking and benefitting from it.
But i was confused because i saw a new post and i thought the thread is new then i got disappointed when i saw it was written in 2018
I am loosing hope, assuming about the activity here i dont think anybody is goind to develop a bootloader unlocking code, i have to use to live with it

Any way to carrier unlock the AT&T V35?

Without AT&T's help?
No, you can contact AT&T, https://www.att.com/deviceunlock
Yes you can. I've done it with a site called unlockplus.
Here you go. Flash one of these KDZ to carrier unlock the phone. You want the ones that say "open" -- which means they are not locked to a carrier.

Top link is for North America Google Fi variant.
Bottom link is for Central/South America -- but if you use that, you do NOT want Claro. You want the other one (carrier unlocked) MIA.
Yeah, flashing an unlocked firmware won't unlock this device. Why in the world would you post something ridiculous like this? How can you have 8185 posts and not know what unlocking means? smh

Just so you know, you're replying to a guy who (besides other feats) made it possible for anyone to carrier unlock virtually any LG V30 model no matter what carrier it was on previously. And that was made exactly by crossflashing. So yeah, I would kinda listen to him.

Because that's EXACTLY how we carrier unlock the LG V30/V30+. We flash carrier unlocked firmware over carrier locked firmware -- specifically AT&T and Sprint variants. The principle should be the same with the AT&T LG V35.
Besides the two carrier locked North American LG V30 phones (AT&T & Sprint), some of the European LG V30 are also carrier locked. Cross flashing the region appropriate "open market" firmware carrier unlocks them.
I haven't done it on LG V35, but I've done it many, many times on the predecessor LG V30/V30+.
We flash V30 firmware and forth at will to carrier unlock the phones, get fastboot flash commands, bootloader unlock, install TWRP and root. The simplest of all these goals is carrier unlock.

He says it won't work. Whereas I've carrier unlocked several LG V30/V30+ doing EXACTLY that. And so have hundreds of other people. I've written a couple of guides on the subject.
While I've not done it on LG V35, I suggested this method because it seems reasonable and logical based on the immediate V30 predecessor.
Something similar (cross flashing) also worked on the LG V20. However, in both cases we had Dev Patched LGUP to use. IF it doesn't work for the LG V35, that would be why -- because perhaps the appropriate .dll has not been used to create LG V35 dev patched LGUP.
I can't guarantee it will work on LG V35, the way I can guarantee it does for the LG V30.

You can flash it and it will boot (not dead, frozen or stuck in Qualcomm 9008 mode like when you normally flash mismatched firmware, picks up signal fine)
Yes I am aware of how to unlock G6, V30 and G7 by flashing a different firmware and I have unlocked several HUNDRED of them. Even LS998 on V22B firmware.
This will flash successfully (I use Octopus tool, the newest LGUP tool is not released so can't do it that way) but it will still show the V350AWM model and will still be locked to AT&T. Only it will remove the AT&T bloatware.
It is a good solution to flash these if you brick your device. But it won't unlock them.

1) Well debloating V35 is at least one advantage others will like, even if it won't carrier unlock it -- and this answer is much better than your first attempt. Can you also now access the bootloader on the V35 and do fastboot flash commands work when, once you flash the open market KDZ? Cross flashing carrier locked North America V30/V30+ to open market US998 allows this, besides carrier unlocking them.
2) If you are aware of how to to carrier unlock AT&T H931 V30 and Sprint LS998 V30/V30+ by flashing different firmware -- like to the US998 V30 open market KDZ -- as well as other LG phone series (G6/G7) using the same technique, and you say you have carrier unlocked "several hundred" by using that technique (with Octopus box, it seems), then your previous insulting post looks like it was written by someone totally ignorant of this Frankenstein process which we use every day to carrier unlock phones like this...

Yeah, flashing an unlocked firmware won't unlock this device. Why in the world would you post something ridiculous like this? How can you have 8185 posts and not know what unlocking means? smh

I have pulled the RSA certs from every model V35, G7, and V40 that are currently available, and LG learned their lesson from the WTF V30 exploit .. they use different certs for every model.
If you have cross flashed the V35, or G7 .. you are only flashing boot and system. If you had flashed an RSA signed partition, you would have had a brick.
I will be glad to post the certs if you like.

Oh sorry I didn't mean it to be insulting at all but flashing these files will not unlock it.
I'm new on this forum. Sorry for being disrespectful.. Everyone is very thankful to you Only WTF? Why would you suggest to flash something if you never tried it before?
To flash I did flash these firmwares but I used Octopus box (super highly recommended)
Lets do something constructive here though. If you have signed cert files let me test it. I have a couple AT&T V350AWM, we can brick them, it is OK. I'll load anything and post results here.
Again sorry about insulting retort but a forum like this should have only 100% clean reliable info.
Hello everyone,
I just bought a LGV35 form eBay for a few bucks but has bad imei is there any chance that I can unlock the phone? I want to use it outside USA, any idea or can somebody help me?
Regards

Interesting, since the G7 and even V35 was released before V30 WTF was discovered (mid-May 2018). @TxanMoe started the WTF thread with his "crazy" story May 14 -- and you helped him unbrick his phone soon after that. I wrote the WTF instructions on May 21.
Well, V35 was released beginning of June 2018, but it was already in the pipeline by May 2018.
The RSA stuff for every variant is probably more an extension of what LG started with T-Mobile H932...
Very sad.

Well, let me clarify. I have only been able to check models that have a KDZ that I can pull the certs from. Any model that either never has KDZ (AT&T or Sprint), or if a KDZ isn't publicly available yet .. I haven't been able to check since I can't get anyone to dump abl.
I will try to post a list of the ones I have checked when the holidays are over.

Hi
I have a lg v35 at&t unlocked and I'm using another carrier(metro pcs) but i can't update it to the latest software version.
Is there any way to get the latest software version?

How did you go about unlocking it? Did you buy it from ATT without a contract.. Did you use an unlocking service or from att directly for unlock?

If you put an AT&T MVNO sim in it, it should update. When I put a Red Pocket Mobile (MVNO) sim in my v35 along with wifi working, it updated the software to version V350AWM10w even though the phone was not yet activated on the red pocket network. If you can find a pre-paid AT&T sim, it should also work, but I'm guessing there.
(note, my v35 is locked to AT&T, I wonder if your phone being unlocked might have some other 'thing' that might be stopping it from updating)

Successfully installed US997 over VS988 (removed V* bloatware)

So I followed directions here: https://forum.xda-developers.com/sprint-g6/help/unlock-lg-g6-ls993zva-sprint-version-t3779966
Went to: https://lg-firmwares.com/lg-us997-firmwares/#tab=firmwares and downloaded: US99721d_02_1211.kdz
Follow all instructions at first link.
I can confirmed it worked for me. Havent had any problems. THIS will NOT allow bootloader unlock (already tried it).
Software Version: US99721d (shows in phone settings).
Atleast ALL V* bloatware is gone.
I am not liable if your phone stops working however, it worked 100% for me and can now use Wifi Calling features.
US997 is unlocked firmware (not bootloader) meaning you can use with almost all carriers.
XDA admin, if this is wrong forum to post in please move for me thanks!
Worked for me. Also wanna try to flash European software, do the TWRP, root and other stuff. Ill give you the feedback if it runs properly.
EDIT: I can confirm that phone works on h870 20H software, but it doesnt recognize sim card. Trying to flash modem from us997. Also i can confirm that bootloader unlock menu is avialable
EDIT: I managed to combine h973 20h canadian rom with h970 20h europe open rom to have all the languages (I'm from Poland). Now I'm gonna try to root it somehow.
As for know I know that US997 and H973 roms works on our VS988 without any problem. H870 have problems with modem, but it has a workaround (do a hybrid rom)
Cool Thanks. I know there are still lots of people that have this phone and want to figure out a way to unlock OR root it. However I'm glad its bloatware free.
So you have EU version phone? Or firmware?
Im on original VS988 > US997. SIM works, wifi calling. OEM unlock toggle works. You did the wipes and stuff in his steps? Im sure you did. Hope you get it working 100% !
So since the bootloader will not unlock all this does is remove bloarware? Still can't root?
Correct. No root. Removes all bloat and gives additional options like wifi calling. Verizon had it but if you switched providers wifi calling wouldnt work. Plus LG theme store is on it for some sweet themes. Some are free but the good ones cost a few bucks.
meh.
think Im just going to break down and buy a US997.
Phone itself is perfectly adequate. Only problem I have is I cant use the navigation app I want instead of stupid Google Maps in Android Auto.
my work phone is an iPhone and I'm starting to think maybe its time to switch. I switched ages ago to Android because iPhones were so locked down. Now Android phones are even more locked down....and the data collection is getting ridiculous.
ooh, this is interesting. which region did you select? there's two (2) available for download with the same kdz name you provided (UCK and UCL, both appear to be for us cellular). not sure what the difference is between the two, if any.
is your phone able to get ota updates after flashing? if so, does it come from us cellular, or is it pushed from verizon still?
I chose UCL. I dont know about auto updates, selecting check for update says "up to date".

was thinking UCL too since the UCK seems to be specific to OK area based on the name. thanks for the confirmation; will try this out tonight.
You're Welcome.
The firmware overall does seem a little quicker. Battery seems to improved. My wife used my phone yesterday for about 3-4 hours. I charged it before she left, she didnt actually use it so I'm guessing it was in standy by. Anyways when she got back it was still at 100% charge. Ive been typing on it for about 15 minutes and its at 99% so seems to be alot better.
I'm on a us997 and I want volte do I just flash the Verizon radio? Also is there a way to do it from recovery? I don't want to do it by PC unless I need to

Hello, you managed to unlock the bootloader?
Nope, I actually dont have time to work with my G6 because it's my daily driver. I managed to install h873 software and everything is working. You can also install h870 software but i think it don't have same antena drivers because WIFI and BT isnt working. I'm gonna to try unlock my G6 on h870 software, but I don't know when it gonna be... I've also tried to root it but every method I tried failed :c Also I think that you can unlock it on h870 without any trouble but SIM, BT etc wont work. The problem is taht when you unlock it on h870 and go back to vs or h873 software to get SIM working, you get locked device instantly xdd
Install US997 over VS988
works as described. used exact OP instructions and 8.0 rom. had to hard reset afterwards but all went well. phone was vs 988 with page plus as carrier. hot spot works after rom replacement per OP instructions. had no need for factory reset. all in all A+.
Hi guys
So I was thinking. Will it be possible to flash a kdz that already has an unlocked bootloader or extract the bootloader and flash it. Any ideas?
How about my phone is easier to use? 997, with this method, but now what I want to do h870 to test the update of android 9 you think work and I saw that the bands should be able to work in theory. The version has no interest in the subject of the root, but if the phone is updated. Sorry for my English

how do i flash the modem from us997 unto the h870? Please help
H870s over vs988
is it a good idea ? My phone has that notification of humidity detected so I can't charge it and I can't deactivated also it's so laggy ? Is it ok ? Cuz I've never done this on a LG
anyone try using US998 or US998z?
US997 does not have Pie. I would say Yet but as old as this phone is getting i doubt there is any work being done on getting it for the us997.

You can root your device now very easily with su98 zip. I have rooted mine and am now looking to unlock the bootloader, no lick so far.
