Note: You can try this with EU ROMs but I'm not sure if it will work, and won't be testing to see if it works, since I see no reason to flash EU ROMs anyways.
I knew this from day 1, but was switching between various LOS ROMs so didn't have much inspiration to make a guide. Now i'm switching back to Stock-based ROMs (due to other roms having no dolby, no voice capture,...), I'll be making a guide
I'm not responsible for bricked device.
This is a guide for those who are facing issues when trying to flash US, EU stock and stock-based ROMs on the chinese axon 7 (no signal, no wifi, worse battery, or simply not booting after splash screen). Since downgrading is also a part of this guide, I will also be covering how to downgrade Nougat 7.1.1 ROMs back to 6.0.1 Marshmallow.
Important thing to note:
You must be on B13, 6.0.1 marshmallow with stock recovery, and please, DO NOT UPDATE TO B10 China NOUGAT or anything above ! This will cause a lot of problem, as from what I've deduced, US B19 is based on the China B09 update, anything above B10 won't be backwards compatible. and will cause problems like not booting, (or no wifi, signal etc after you recover the boot partition through recovery)
Now, if you're already on Nougat and want to try this guide, downgrade back to Marshmallow using EDL. Try this guide:
- Download B13 EDL (credits to djkuz from 4pda), extract it
- Download and install the latest Xiaomi MiFlash (stable or beta)
- Turn off your phone, plug it in to your PC, Hold Power + Vol Up + Vol Down, go to device manager, look for the "Port" section, and you will see something like Qualcomm HS-USB QDLoader 9008., if you see it, proceed down below. If not try again.
- right click , open properties on the Qualcomm HS-USB QDLoader 9008, go to port settings, if you see the speed is at 9600 bits per second (bps), change it to 128000 (you can skip this step, but doing it will increase your flashing speed)
- Open MiFlash, press select and pick the folder you extracted a few steps ago.
- Press refresh, if you see your device appearing on the list, press flash. (if some random errors appear, unplug the device, plug it back and immediately press refresh and press flash)
- After flashing you'll be back on B13 China Marshmallow.
REMEMBER, DON'T OTA UPDATE IF YOU WANT A SMOOTH TRANSITION TO US ROMS:
Now, to the good part:
- Download the B09 China OTA package from here (credits to Demons-77)
- put the package into your EXTERNAL sd card, internal won't do.
- reboot to recovery (Power + Vol Up)
- select the option with the word "sd" on it
- now go and pick the package that you just put in
- It will begin flashing and after that, you will have B09 China Nougat
- reboot to bootloader and install recovery (fastboot flash recovery *your file name*)
- after that you can install any roms you like, no need to backup and restore the boot partition every time you flash a US ROM, and you won't encounter strange issues like no boot, no wifi, etc.
TL;DR for those who already know how to do most of these: go back to China Marshmallow through EDL, update to B09 China Nougat with stock recovery, install TWRP and then flash whatever US stock or stock-based roms you want (just like how you would with a US phone)
Does custom kernels work after installing US roms?
I want to have a magisk compatible rom but I don't want to install custom roms other than stock.
Chinese roms doesn't boot with these existing kernels in this forum.

what do you mean by magisk compatible rom? I'm running the latest badboyz with magisk root here, no problems at all

Ok that's great. Last time I tried badboyz, I get issues with my signal keep restarting. I'm currently using chinese B01 mifavor5. all is well, just that I can't use magisk due to the stock kernel.
Thanks for your feedback OP.
Hi, great tutorial, but I got few questions. Now I'm on chinese nougat (B15) and if I downgrade to mm, will still I be able to do this operation? Can I relock bootloader on US rom? Because some apps like android pay, pokemon go and snapchat won't work.
@spiwar Mate I could kiss you right now. But could you just point me to one of the us stock ROMs to flash? (E.g, is this one alright - A2017UV1.1.0B19_StockSystem_by_DrakenFX.zip)
Is it safe to perform ota updates of the USA firmware on Chinese axons? Cheers

Downgrading IS a part of this operation if you're already on Nougat (you need to go back to MM before you can go B09 Nougat). Why relock your BL though? Magisk root can work with Android Pay, Pokemon Go AFAIK, not sure though (since I don't use any of those apps)

Yes that stock ROM will be okay. Personally I'm using the latest version of BadBoyz ROM.
No you can't. Because OTA updates requires the stock recovery, and your phone probably won't boot if you flash the US Stock recovery

Magisk won't work if you're using B10 Chinese as a base (as mentioned above), if you flash on B10 you'll have to flash the boot portion from the stock Chinese ROM for the US ROMs to even boot, and then you just lose magisk.
I see. Thanks for the tips. But I don't think I'll be coming back to b13 mm for that. I hate restoring data ang all the files in my internal storage.
Hi!
Could you please clarify me a doubt?
To follow this guide, must my device already be rooted?
Thanks!
Well, first part went well. After a lot of effort, because device was recognised as DFU. Anyway, I got it back to B13 with stock recovery.
On second part, when I try installing the FOTA update, it fails, giving me error: status 8. In update history, it says that the system package did not match the phone. Obviously I have A2017.
Any suggestions?
I bought a LG V10 today i dont know if its used or new (LOL) any way to find that out i checked IMEI says its orignal talked to people at LG USA they said its Original Here are my questions:
1) How to know if your phone is Legit like New + Lasting?( in my country they replicate used to orignal or fake to orignal)
2) How to Root LG V10? (i tried it with other phones i broke them)
3) Suggest Some Recommended Apps and ROMS?
4)I have seen a youtube video of xdadevelopers they were talking how you can overclock or under clock your device can i do that with my phone?
5)Last Question How can i myself from the infamous Bootloop? (Any Suggestion, Tricks Ways)
I am new here i need your help for not doing a rookie mistake....
1) Get the LG Phone Info app on the Google Play Market and as long as that shows "OK" in the Original info (the first box after you click the Get Information button) then your device is an original and not something that's been modified on a firmware level.
2) If you have Lollipop or Marshmallow rooting is fairly easy by comparison to Nougat. If you have Nougat on it already things are basically a stop - there is no working root for Nougat at this moment IF the device has been upgraded to Nougat using T-Mobile's OTA direct from them. Once that's been installed there's no turning back and no working root at this point but some devs are working on it, no guarantees they'll ever be able to create one.
If the device has Lollipop or Marshmallow on it you can get it rooted. The best course of action is to go from Lollipop to Marshmallow (the last Marshmallow build is 20l and that's an "L" there, lowercase, not 1 or i/I) and then what you'll need to do is get TWRP on it (that step is critical) then you would flash this modified update.zip to get to Nougat build 30b on it. runningak3d modified that update.zip file so it does NOT overwrite the recovery partition and you get to keep TWRP installed for flashing purposes. If you use T-Mobile's official OTA update.zip you'll be stuck, not able to flash anything including TWRP, or get rooted, etc.
So, again, the process is get to Marshmallow 20l, then get TWRP installed - at that point root is not necessary just to get the modified 20b update.zip on it. Then use TWRP to flash that modified 20b update.zip at which point it'll be Nougat, and THEN you can flash SuperSU with TWRP and you end up with a V10 running Nougat and rooted, that's the only method at this point.
runningak3d said he (or she, sorry, I just don't know) would try to create another modified update.zip which is pre-rooted so when installed you've got root/SuperSU ready to go but it's barely a minute to install SuperSU manually after flashing that modified 20b update.zip so it's not really a big issue there.
3) There are no custom ROMs for the V10 at this point, no Lineage, no AOSP, nothing really. There are some modified stock ROMs iirc but nothing that's totally custom and we V10 owners are still hoping some dev will take some time and create an unofficial Lineage build for the V10 based on Nougat (or even Marshmallow, I don't really care which Android version it's based on just that it's Lineage through and through). It seems pretty screwy that nobody seems to care about the V10 enough to have created a custom ROM but that's how it goes sometimes. The V10 is like an LG G4 on steroids in some respects, basically the same hardware overall with some minor differences (the second screen, of course, but I don't even use that on mine so I don't care about it at all).
I just wanted Lineage because it's so lean and efficient compared to any stock ROM and of course the potential for having a custom kernel with more governor support and other aspects is the big draw for me so, the hope remains that someone out there will take some pity on us woeful V10 owners and drop a Lineage build someday.
As for apps, well, that's entirely up to you and what you use your V10 for, and since nobody knows that but you then it'll be up to you to decide what kinds of apps you're going to be looking for.
4) Over-and-underclocking requires a custom kernel that allows for such things, and the stock kernel that's available (I think there was one custom kernel but it's just a modified stock one with limited additional capabilities) simply doesn't allow for such alterations. The V10 is quite fast on its own natively so, I can't imagine why someone would need to overclock it - I can understand WHY someone would WANT to do it, of course, but as for an actual need to do it, nope.
As for underclocking, that would save battery and be what I'd call a need in some respects, but again there just doesn't seem to be any developer out there that gives a damn about the V10 sadly. I wish I had spent more time learning how to create custom ROMs over the years and trick out some kernels as well using the provided source from manufacturers of these smartphones but I never did.
5) There is no way to prevent the potential bootloop issue which affects the G3/G4/G5/G6 (I saw one report so it could be bogus for the G6) and also the V10/V20 (seen two reports for the V20) and the Nexus 5x because it's a hardware manufacturing defect related to how the Snapdragon SoCs are mounted on the motherboards. There's nothing that you can do about it and there's no way to know for sure if the V10 you have will develop problems because of it or not, all you can do is use it and be done with it and hope for the best. Again, there is no fix and there's no way to know or prevent it from happening so, no matter what so called "fix" you read about or see a video about, it's all BS and best avoided.
My recommendation: since you just got the V10, go to LG's website and register the V10 in your name (might have to create an account) and then say you bought it in March, April, or May of 2017 (just a few months ago) and that will give you warranty protection through at least mid-2018. If you do that and it does bootloop on you, LG will replace it through the warranty period. Don't register it and you're out of luck if it does bootloop on you.
Hope this helps...
So, I've been "out of the scene" for 2 years +some months and I can't find clear answers to how I should do to get what I need. I need your help...
What I want to obtain: I want to have my LG G5 (H850) updated to the last firmware version (it should have andrioid 7, right?), rooted, and with Magisk installed. Xposed too, if it's possible in android 7. It is, right?
What I have right now: a rooted phone at FW version V10d-EUR-XX with Xposed installed (bootloader unlocked with the official method), android 6.0.1.
I don't know where to start from, since I can't find specific guides that tell me what to do, I have to ask here...
For example, do I have to reset the phone and install everything from scratch? Should I un-root the phone and install the firmware updates in the official way, or can I do it with some tool without un-rooting? Can I keep my installed apps & data? I don't know...
Thanks for any help... sorry if I'm demanding a lot, but I've always found it pretty hard to find definitive guides (or just definitive answers) in the android scene.
Well the first part is easy, use lg bridge to get the latest firmware..I'm doing it as I type..then I need to install adb and fastboot to install twrp and magical..
Latest firmware is 20x
Thanks for the reply.
So, if I already have TWRP, I can update the firmware with lg bridge and then I can simply install magisk? I thought I had read that if my phone is already rooted magisk can't hide the root, or something.
The firmware flash will take the phone back to stock..root gone..twrp gone..so install twrp through CMD window is needed..just make sure you have the magisk files on a SD card
Back to stock means, completely? All my apps and data gone? If yes, is there some tool to restore them easily after the firmware update?
And when I install magisk, if I need root do I simply have to install magisk's "root module"?
LG bridge shouldn't delete user data..I thought it did..but after doing it, it didn't..it just upgrades the firmware
Thanks. What about Xposed? Will it remain or will I have to install it again? And, since it requires root, does it mean that I have to enable root with magisk to use the Xposed modules otherwise they don't work? Like, that when I disable root they stop working?
Never used closed so I don't know..if lg bridge leaves user data alone it may leave root alone but then again it may flash stock boot image..so not sure really..
I don't mind reinstall lots of apps again as long as my pics are backed up.so I would reset phone...flash firmware..then twrp..then magisk..
Ok then, but I don't know which firmware I have to use.
For example, the latest in the list (here, ordered by date, descending) is "H85020t_00_TMO_COM_OP_0514.kdz" but it says "TPL - Europe - PL/Poland". My phone isn't from Poland, it's from Italy, and there's no firmware with that same date for Italy. Should I just use the newest one saying "Italy"? I dunno...
I also saw that, for the same country, there can be different updates for different providers, but I'm pretty sure my phone had none (it was "unbranded"). So which one should I choose?
LG bridge will automatically download the latest one for you..use error recovery
Oh, that's great.

There's update zips available in the development section. You just flash the COMPLETE version of one of those in TWRP and you're done.

Is it any better than using LG Bridge?
And would I need to make a Nandroid backup just in case, if I wanted to flash those zips, or is it safe? 'Cause I'm having trouble with that, as I wrote in the other thread...
Thanks
Ok I'm done, I updated the firmware with LG Bridge and installed Magisk & Xposed (through Magisk). Xposed isn't activating itself but that's another problem.

Yeah I know, but at least now I know how to do the whole procedure almost painlessly.
I am struggled flashing the Android 10 cook rom in my LG V30 North American variant, specifically US998 model. Of course there is nothing wrong at flashing process. No crashing, no bootlooping, everything processed pretty well until I kept getting Wifi issue all the time. I attempted various of solutions like Jeff's backup, Oreo Modem, and other kinds of solution but no luck. And of course, I won't have any ability to access to Wifi if I kept on using Q ROM. I am just a newbie here so I don't know if it happened on Pie as well, but currently, I am running Havoc OS 2.9, and it worked perfectly fine. I flashed straight through Pie KDZ, so I'm afriad if it made permanent change to my device that prevented the Wifi to work ( Yes I already read the note, and it said to LOS 16 based rom, but I am running fine, nothing happened lol )
So am I permanently not able to use any kind of Android Q ROM Cook anymore, or am I able to get Wifi to work if I kept waiting and waiting for a completed stable version? Ty
Android 10 is completely stable tho, wifi is a hit and miss, try to downgrade to H933 and upgrade to stock pie, then flash android 10 again, nougat always seemed to fix stuffs, canada variant in particular, look in ChazzMatt's threads for flashing stock pie, there is a workaround about how to flash H933 nougat
Wait. Do I need to flash directly from LOS-16 based to Nought Partition DL and then flash KDZ to Pie, or stock Oreo first then Nought?

Here are the links about H933 nougat downgrade, try it, apply the Q wifi fixes if necessary and let us know how it went
Nvm. I have no idea how stupid I am ?.
The thing is, I did put the Jeff's backup folder on TWRP folder, but I cant get why I did put it straight to backup folder but not the folder with my model printed in the title. There is a folder inside the backup folder, I put it in there, and I got Wifi. How strange it is lol
Anyway, thanks a lot for your support
Hi!
I have a VS996 with an unlocked bootloader and TWRP. I went from stock, did a full wipe (Dalvik, System, Data, Internal Storage, Cache), and tried flashing Havoc-OS (Android 10) and had issues with connecting to Wifi. So I went back to JohnFauxes VS996 flashable and now I don't have data or a working camera. Not sure what's going on here. Ideas?

Went from stock what? Stock Oreo, Stock Pie? You have to be on stock Pie to go to LOS-17/Android 10 ROMs. LOS-17 requires LG stock Pie blobs (drivers). Yes, some have Wi-Fi connection issues. There are workarounds.
Went back to JohnFauxes VS996 flashable what? Last Pie, last Oreo? Something in between?
Going from LOS-17 back to stock you will have sensor issues which can be overcome by running in permissive mode. Other ways to overcome it is to Partition DL back to Nougat to scrub the device of all lingering LOS-17 ROM scentk, then upgrade back to newer firmware. If you don't want to do that then you need to run in permissive mode for camera to work.
I don't know what's wrong with your data.

Went from stock Verizon Pie ROM, to Havoc 10 Q. Then from Havoc 10Q to latest John Fauxes Verizon Pie. I'm not sure how to run in permissive mode or the partition DL I'm afraid.
Glad to have you replying. My goal is to have Android 10 Q on my wife's Verizon phone. Not sure if the 'call to activate modem' bug still exists, to where you can't receive texts unless you call after reboot.

(Ignore that in some of those posts they are are calling it Q ROMs. It's Android 10. Q was merely the beta letter name for what became Android 10, and some people don't want to give that up for some reason. "N" letter beta became Nougat, "O" letter beta became Oreo, "P" letter beta became Pie, "Q" letter beta became... Android 10. Yes, Google ditched the dessert name, but STILL you no longer use the beta letter name when it graduates and gets a statue in the Google Android Park. Call it "10" if you wish, but don't call it "Q." That's like calling a butterfly a "caterpillar". That was just the beta stage of the butterfly!)
____
The major problem you are going to have with V30 Android 10 ROMs is VoLTE -- or rather the lack of it. Read #5 of the V30 Custom ROMS FAQ. End of this year -- 2020 -- Verizon is dropping CDMA. They were supposed to do it end of 2019, but delayed a year. I don't see them delaying again. This means when you make a phone call you will not be able to drop down temporarily from 4G LTE to 3G CDMA for the phone call. You will need VoLTE (Voice over LTE) for all phone calls. Stock firmware has this capability. However, no V30 LOS-based custom ROMs have VoLTE for any carriers.
On V30 you can only get VoLTE on stock firmware or custom ROMs built on stock firmware.
This is September 2020. So, while you can use V30 Android 10 ROMs, in about 3 months you will have to go back to at least rooted stock Verizon firmware to get VoLTE.
T-mobile is dropping 3G HSPA in January 2021. Of the major U.S. carriers, 0nly AT&T is holding out. They will drop HSPA in February 2022.
Discussed in depth here:
All U.S. V30/V3O+/V30S will need stock firmware, not LOS-based custom ROMs. When?

Thanks for all the info. So I think I should go for your clean flash method by setting a partition, because I tried the WiFi fix and it forced me into Safe Mode and wouldn't otherwise boot. I think I found a flashable stock Nougat ROM, after which I intend to flash MSM Extended and get that working hopefully. So do I create a new partition in TWRP, use that for Nougat then empty the previous partition, flash Android 10 to it and get rid of Nougat again after that? Never done this before.
And setting permissive mode is done through a separate APK? Your link went to a post talking about how they used an unlinked APK to get camera and flashlight to work.

I can't say I'm familiar with that MSM Extended ROM. I do see it listed in the LG V30 Telegram Update channel.
If you found a working flashable stock Nougat ROM (there were two versions floating around -- one that kept TWRP and one that replaced TWRP with stock recovery) which keeps TWRP, then after using that you can flash back to stock Pie with TWRP flashable zip (you need Pie blobs for LOS-17 based ROMs), then install the LOS-17 based ROM/Android 10 ROM of your choice.
I'm confused about your question of creating a new partition. All you will be doing is flashing back to Nougat to ostensibly repair previous LOS-17 effects. Then flashing back to stock Pie firmware, then flashing your choice of LOS-17 based ROM.
The only people who create new partitions are those who want to use GSI (Treble) ROMs. Those ROMs are inferior and rely upon a user-created "Treble" partition since V30 never had official Treble. Those GSI ROMs lack many stock V30 features which "regular" LOS-based ROMs have.

If you found a working flashable stock Nougat ROM (there were two versions floating around -- one that kept TWRP and one that replaced TWRP with stock recovery) which keeps TWRP, then you can flash back to stock Pie with TWRP flashable zip (you need Pie blobs for LOS-17 based ROMs), then install the LOS-17 based ROM/Android 10 ROM of your choice.
I'm confused about your question of creating a new partition. All you will be doing is flashing back to Nougat to ostensibly repair previous LOS-17 effects. Then flashing back to stock Pie firmware, then flashing your choice of LOS-17 based ROM.

I'm hoping I found the Nougat ROM that keeps TWRP here. When you mentioned "Partition DL back to Nougat" I took that as me needing to create a partition somewhere. Also I did indeed find MSM Extended on the Telegram Channel here.
All's I know is I need to get my wife's phone working before I go to bed (night shift), else she's gonna kick my ass for wiping it in the first place thinking I could just pop Android 10 on there. Ha. So whatever I need to do, I'll do it.

When I mentioned going back to Nougat via Partition DL I was talking about going back to full stock KDZ, not using a Nougat TWRP-flashable zip. Doing it the old-school way I was suggesting is harder but more thorough. You would use Dev Patched LGUP to go back to Nougat, wiping out TWRP. You would still have unlocked bootloader. Then you would LGUP to a Pie KDZ which has fastboot flash commands, then reinstall TWRP, reformat internal memory, then flash an Android 10 ROM.
Your way is easier.

That link is to JohnFawkes 20k, which is Oreo. Nougat starts with 10 then letter.
Nougat = 10 + letter
Oreo = 20-something + letter
Pie = 30-something + letter (except for Sprint which didn't go by the LG naming rules)
The Nougat TWRP flashable zips were released in the Telegram thread.

Okay... I'm nervous. So you think I can do it without messing up recovery? Darn it.
Could I be so bold as to ask you if you have an instant messenger of some sort? I would greatly appreciate it!!

Flash back to 20K Oreo for now. Use the Permission changer app to make it be "permissive" so camera works OK.
That Oreo is stable. You don't need Pie for now -- if you just want to make the phone work.
If it works, then you can flash back to Pie TWRP flashable zip later if you wish.
In the future you can find the Nougat TWRP flashable zip posted in the Telegram thread.
I'm about to take a shower and go to work. Sorry I can't do Messenger app.
