Hello,
Today I tried to Root my V10 using this method: http://forum.xda-developers.com/lg-v10/general/root-h960a-tot-add-systemrooted-t3337706
and now it gets stuck while booting. Is there a way to reflash the Original Firmware? (and keep my files)
I tried the "update error Recovery"-Feature in LG Bridge but the download goes really slow and I don't know if it can help me at all.
I hope someone can help me here

Hi,
you should try to flash the appropriate KDZ file with LGUP. There is also the possibility to upgrade the phone and keep the data. You'll find the KDZ file and the link to LGUP (including description how to flash) in the first post of this thread: http://forum.xda-developers.com/lg-v10/general/kdz-download-lollipop-kdz-10c-lg-servers-t3332348.
Make sure you select the correct KDZ file depending on the version of your phone (H960A for Europe or Middle East).
Hello everyone sorry for the English this using google translator.
I have a problem search the forum but I did not find my problem promptly.
I recently bought a LG V30 VS996 reizon aliexpress verizon which came with oreo 8, I am from Arentina, these days I got an update to 9pie which I accept download and I gave it to update and I have the problem that it stays loading in the verizon logo I can enter download mode, but when I want to update with LGUP it detects that the phone is a US998 and not a VS996 I have no way for the LGUP to detect that it is a VS996 probe with patches, different versions of LGUP, now I have the doubt if my VS996 is a frankestein?
What step do I have to follow to recover my V30? can i flash a kdz of us998?
please help

You need to use Dev Patched LGUP and you need to read the Frankenstein instructions.
Unless you're a Verizon customer it's probably better to use US998 firmware.

thank you very much, could you tell me where I find Dev Patched LGUP and the frankestein guide.
or you say that if LGUP detects me that it is a US998, just install that KDZ of US998, I am in Argentina, so Verizon services do not use

Please read the 1st 10 posts of both guides carefully.
https://androidfilehost.com/?fid=6006931924117925289 (LGUP file)
hello thanks for the help, you say it is convenient that I use LGUP and flash a KDZ of US998 in my supposed VS996? since I supposedly have a VS996 and LGUP detects me that it is a VS998.
Can the KDZ ROM be exchanged between these two models?
I am from Argentina and I do not use any of these companies, only the 3g and 4g bands that are the same in Argentina.
The next question is if there is any guide here to use LGUP since I did not find or know what words to use in the search engine because of my English translation.
Thank you !

I got the same problem, but mine is a US998. After I update to Pie in OTA, is stays in logo. What shold I do? Re-flash with the Pie, or go back to Oreo? What you recommend?

Go to US998 20h (last Oreo, it's the best of the Oreos).
This first US999 PIE is wonky and some people have problems updating to it. We have a workaround in post #6 of the US998 Pie KDZ thread -- but it involves bootloader unlock and TWRP. It's a little complicated for anyone who isn't even rooted yet.
I'm suggest flashing to US998 20h (not 20b!) and staying there until another US998 Pie KDZ is released.
Hello again, I read the guide that happened to me kindly, but there are some points that were not clear to me and I want the advice of the expert experts here.
First when I install the LGUP from the link that happened to me I follow all the steps but I can not enable the developer mode and when I connect the phone I get this legend
Ask me to install a valid DDL, how would this be?

When I manage to open the LGUP from an icon that is in the folder where I unzipped the files, open the LGUP but it detects me as if it were a US998, at this point I would have to flash a KDZ of US998 on my VS996, with the method mentioned there?

If you are using the LGUP from the Frankenstein instructions, the .dll error means you didn't install it correctly.
I don't see you mentioning the SetDev.bat step?
After Installation, you launch Dev Patched LGUP by using the desktop shortcut, not through an icon in the folder.
Uninstall LGUP from your Programs folder, and reinstall.

Hi @ChazzMatt, I could finally flash it, I tried it on a different computer and with Windos 8, I detect the phone perfectly I could do cross flash, from US998 that detects LGUP to VS996, I perform the flash perfectly at 100.
But it is restarting in the Verizon Logo just as it was not restarting, it is still the same, try the master reset that they cite in the guide post, but I perform the master reset and it remains the same, the truth that I would not know what to do, Can't get into the android system, only the LG V30 logo appears and then the Verizon logo and it is loading, but from that screen does not happen, any other alternative to leave this part?

Your earlier screenshots show you trying to go straight to VS9930 Pie 30c from US998 Nougat 10c. Are you still trying to do that? Frankenstein instructions specifically say you have to flash Nougat first, Master Reset, then you can update to newer firmware.
This means you need to flash VS996 Nougat, Master Reset, then update to newer VS996 firmware.

@ChazzMatt Thank you very much, I took it to a technical service, where they have octopusbox for different services, but they could not do anything, it seems to me that they do not know how to manage the different octopusbox options and only the most classic ones such as unlocks, flash and releases, I will try Again with the instructions you give me, I thank you very much for all the information and the time you take to read, thank you, I will be keeping you updated :bueno:

What I did was flash us998 kdz, install twrp, backup efs, modem, everything. Then did a chip erase in lgup.
Flash oreo Canadian kdz, then us998 kdz, install twrp, restore efs. Then flashed VS996 30c pie rom and like a miracle from Jesus it booted! [emoji106]

Flashing chip erase will wipe out IMEI and serial number.
Your phone was brought back to life by Octoplus or something a few months ago, right? So you have stuff in your phone that's different from most people.
In all the LGUP instructions I tell people to not mess with Chip Erase.

That was my original vs996. I got a second vs996 that I'm using now. If you backup efs, you can restore your imei. My serial is gone, but I don't need it, and now I can boot Verizon Pie.
OK never mind battery died overnight, charging now to go back to us998h.....
Ok converted v30 locked boot, no root us998h to vs996k, all went fine. it upgraded to L then tp pie vs996. Now just sits at verizon screen with colored dots. Did master reset and satill the same. Used partition dl for K and went just fine. How do I get back to phone off to redo vs996k and reject pie upgrade' Thanks
Upgrades were ota
I want to know if frankensteining a carrier unlocked us998 to vs99(Verizon version) is just a quick one step process to latest Pie, or do I need to install all updates one by one? The us998 is activated on Verizon and has Android 7.0 on it. Thanks.

One of the trouble shooting tips in the Frankenstein post is to reinstall drivers, another is to try a different computer.
The dll error ALWAYS means either you didn't install the correct version of the Dev Patched LGUP or not using it correctly (like not launching from desktop shortcut, but instead trying to use the folder .exe file). If you are sure you have installed correct, have installed all the correct drivers, then try a different computer.
Thanks for reply. I've tried all steps from the post. Reinstalled, deleted, restarted. Only thing I haven't done is try a different computer. I get "LGUP can't load the model[c:\Program Files\LG Electronics\LGUP\model\com" error. Am i missing a file?
I noticed that the program also installs onto my C:. I also have to delete c:\LG Electronics folder. Is this normal? I've downloaded LGUP Dual from both links in the post. I guess i'll try a different PC. Thanks for your help.
I got it to recognize! Had to try on another computer but now it works. One more question though. Do I need to make a backup? If for some unknown reason I need to get back to the original software, how do I go about doing that? I have us998 with us99810b installed with Android 7.1.2. Thanks again.

You would simply do the reverse. You would flash your phone back to US998 KDZ. However, US998 10b was very early Nougat. If you ever go back to US998, like to sell the phone or something, I would at least flash to newer US998 firmware -- like 20h (last Oreo).

Actually it's VS996, for the Verizon V30, not VS9998.
So you're on US998 Nougat?
Technically for Frankenstein, using Dev Patched LGUP you should Partition DL to VS996 Nougat, use Master Reset, then Refurbish to VS996 Pie.
However, US998 and VS996 have a level of compatibility the others don't enjoy. I think you can Partition DL straight to VS996 Pie, followed by Master Reset.
If you're not sure what Master Reset is (sequence of button), see the Frankenstein instructions.

Thanks for the reply. Do you recommend going straight to Pie? If its more reliable in steps ex. Nougat, Oreo, Pie, then ill do it. I was just wondering if jumping straight to Pie would cause issues.

No, won't cause issues if you're using the KDZ.

You're not Bootloader Unlocked and rooted, are you? You don't care about that? It's fine if you don't. Neither is my wife's, sister's nor brother-in-law's V30/V30+.
BUT if that is something you would want, no, you can't go straight to VS996 Pie until you do some other stuff.
But if you just want Verizon firmware, then you should be able to jump straight to VS996 Pie from US998 Nougat, going by what other Verizon users have done. Use Dev Patched LGUP in Partition DL mode, with all Partitions. Then Master Reset.
If for some reason, doesn't work, then tour would need to flash VS996 Nougat, Master Reset, then VS996 Pie.

You are basically asking about Frankenstein, where one North American variant can be fully converted to another (firmware, modem with LTE bands, etc)
Normally, for most North American variants, when flashing KDZ (LG stock firmware image) you actually need to downgrade all the way to Nougat first before upgrading to more current firmware. See Frankenstein instructions.
But US998/VS996 have a very close relationship. If have US998 firmware on the phone, you can go straight to Verizon VS996 Pie firmware using Dev Patched LGUP. For this specific combination you do not need to downgrade first.

Thank you!! I did some more searching around the site late last night and am going to try it tonight. The main reason is because i just switched to Verizon and the WIFI calling option disappeared even though it was "turned" through Verizon. It seems to be that even though I have a carrier unlocked phone, Verizon doesn't see that and will block certain features unless it is a Verizon phone. I have access to the network, but not the wifi calling
So I'm still having issues. I've downloaded and installed drivers and LGUP Dual mode from the link and can't seem to get it to work. I get the phone into download mode and it goes into the firmware upgrade screen but my LGUP doesn't load. I get a "LGUP can't load the model[c:\Program Files\Lg Electronics\LGUP\model\com" error. Any suggestions?
Just trying to install VS996 onto a Verizon enabled us998 so that i can get wifi calling, visual voicemail and video calling to work. Thanks

See the trouble shooting tips in the Frankenstein Instructions. How many of those have you tried?
Sounds like LGUP wasn't installed correctly. It needs to be installed using very specific steps. There are other possible explanations, but this is where I would start.
Uninstall LGUP completely (in Programs & Features control panel), then delete all its remnants and folders and restart Windows (not Shutdown, Restart).
Now download LGUP from the link in one of ChazzMatt's Pie KDZ ROM threads, and install it EXACTLY folding the steps he gives, no shortcuts or deviations.
If it still doesn't work, follow his troubleshooting steps in the same ROM thread.
Edit: Oops, Chazz beat me to it.

My V30 doesn't seem to enjoy being flashed with Android 10, as it bootloops no matter what ROM I decide to use (Lineage, Havoc, Pixel Experience), and now I'm thoroughly stumped on what to do, as I can't find a fix for this issue. My phones bootloader is unlocked via Frankenstein, and I've used the method of flashing over 10d with 30b and having no luck. I've recently come across a post that said to attempt trying 20b to 30b, which I'll try as a last effort to get this working, but I'd still appreciate advice on what to do. Whether it be this last method, a modification of it, or just something else entirely, I'd be forever grateful for the help.
If you need more information, feel free to ask and I'll provide to the best of my ability.

1) You need stock Android 9 (Pie) as a base before flashing any LOS-17 (Android 10) ROMs. But you seem to know that.
There are several methods to update to to Pie US998. See US998 Pie KDZ thread, post #2 and FOUR MORE WORKAROUND in post #6.
2) What variant did you start with? If you have former AT&T H931 or Canada H933, you'll need to do additional prep steps before installing any LOS custom ROMs.
Of course, you've read the V30 custom ROMs FAQ -- before you even unlocked your bootloader -- right? It tells all this and conveys other important information. This FAQ is prominently linked in the WTF instructions, with suggestion to read first, then come come back to finish unlocking bootloader...

Yes, I did read through the FAQ before and after unlocking. My variant is the US998U/V30+, which is why I'm a bit confused. The US998 and US998U are identical, aside from storage capacity, right?
I was following one of the guides you posted that stated:

So for installing the KDZ, I suggest FIRST downgrading to US998 Nougat 10d via Partition DL mode, Master Reset, then Refurbish to US998 Pie KDZ. Here are the steps...
If you have problems flashing this US998 Pie 30b KDZ, see post #6 for FOUR more workaround methods proven to work for some people.
You should probably use this method (DOWNGRADE to NOUGAT first) even if you have TWRP installed. Then reinstall TWRP again after successfully updating to Pie.
KDZ INSTALLATION INSTRUCTIONS
0) Turn off phone, manually go into Download mode before opening Dev Patched LGUP.
1) Using Dev Patched LGUP from THIS thread, flash US998 10d Nougat KDZ via Dev Patched LGUP using Partition DL mode. Select ALL partitions.
2) Master Reset. This is NOT Factory Reset.
3) Boot up to Welcome screen. Turn off phone, manually go back into Download mode.
4) Flash US998 30b Pie KDZ via Dev Patched LGUP using Refurbish mode.
5) Master Reset. This is NOT Factory Reset.
If you did not unlock your bootloader before doing this, then you bootloader is still locked -- because that's what you want. Finished. Set up your phone.
If you had unlocked bootloader before doing all this, you will still have it. Boot to ADB, and PLEASE follow these instructions for re-install TWRP and root!!

So that's what I had done a few days ago, but that's also when my problems arose. I was on the TWRP flashable kdz of 30b for a month or two now after Frankensteining it, but wanted to try out some 10 ROMS, but attempting to flash those ROMs was when I started having issues. Flashing the stock US998 kdzs didn't cause issues, the 30b zip I had been running daily wasn't weird, and the md5s for all the files downloaded matched what was provided as correct. That's why I'm a bit stumped, since I believe I followed all the guides I've looked at to make things work correctly, but this one part is giving me a hard time.
I will try those other four methods, since I don't believe to have seen them yet. I will provide an edit to this post after trying them, thank you.

If you Frankenstein'ed, I'm asking what your original variant is. Frankenstein is to convert North American variant to another, also called cross flashing.
Whereas " WTF" is bootloader unlock and installing TWRP. Some North American variants have to Frankenstein to US998 for fastboot flash commands. Then they can use WTF INSTRUCTIONS. But Frankenstein itself is not bootloader unlock, TWRP and root. It's just fully converting one variant to another. It ONLY works with the North American variants, except for T-Mobile H932.

OK, so you were on LG US998 30b stock Pie successfully.
Put your IMEI into this database and tell me what it says? Don't post your IMEI here, publicly. Just curious what variant it says you have.
https://www.imeipro.info/
If you have V30+ US998 , then it's either native US998U or was formerly LS998U and converted to US998 by you or previous owner if you bought it used.
Neither AT&T H931 not Canada H933 have a native V30+, but I've seen H933 V30+ which were Frankenstein'ed.

Ahh, alrighty, I understand the difference now. So I had Frankenstein'ed to unlock my bootloader, then unlocked it with "WTF".
Also, the IMEI checker reported my device as a US998U V30+, which was what I bought it as used.

Merely downgrading to earlier firmware is not Frankenstein. Frankenstein is fully converting one variant to another. It takes on those different LTE bands, etc. Cross flashing AT&T H931 to US998 gives it CDMA bands the H931 doesn't have, different LTE bands, fastboot flash commands. Same with Frankenstein'ed H933. See screenshot.
If you already had US998 firmware and your IMEI check says it's a native US998U (V30+), then you didn't Frankenstein to US998. You already had US998 with fastboot flash commands. You just used LGUP to downgrade to early US998 Oreo for WTF bootloader unlock, TWRP installation and root and/or maybe you went to US998 Nougat at one point. But you were already US998. You weren't on LS998, AS998, H933, H931, VS996 firmware, at any point in time.
Why you are bootlooping on LOS-17 Android 10 ROMs, I don't know. You don't have former H931 or H933, and you said you were on US998 30b (Pie) when you tried to flash those ROMs.

Should I attempt to Frankenstein to a different variant then come back? I was going to try to use the fourth method that you linked to before to try to put myself on an actual US998.

The problem with Method #4 is you are willingly converting to Canada H933. While that might get you back to US998 30b, it will then give you more difficulty in flashing LOS ROMs. You have to go through the tedious extra steps of former H931/H933.

As someone who doesn't necessarily mind the extra preparation, would you recommend it for someone in my predicament? And is there any log file I can provide to hopefully help give more insight?

That's your decision. It should get you back to 30b. After that, for flashing ROMs, you'll have to follow the other instructions for H933 (since you will have converted to that, then converted back).

Though if I am to do that, would I still keep the bands I have at the moment or would I lose them when converting? Would I have to refflash my modem partition(s)?

The method is flash to H933 Nougat I believe, then flash back to US998. You don't stay on H933. You flash everything via LGUP Partition DL mode.

Ah alright, I'll try that. So just to clarify, I'd flash over to an H933, then come back to a US998, and then install the 30b kdz, and that should hopefully fix my issues?

Yes. But read Method 4 carefully. Involves timing and buttons.

LGUP doesn't seem to recognize my phone as a H933 after flashing and rebooting back to download mode, but the phone seems to know it's one when I flash and it says what build it's on and what's being flashed.
EDIT 1: Reinstalling LGUP fixed that particular issue, so I'll have to restart the procedure just so it's as unobstructed as possible.
EDIT 2: Never mind, still the same strange occurrence that happened before. I'll try to move on and see if it'll still work.
Okay so, after a lot of trouble, everything seems to work. I ran Jett's Wifi Backup fix to fix the broken wifi on Havoc, along with the Haumea kernel, and now everything seems stable.
Thank you for your help!!
I guess I just had to keep doing the procedure until it stuck
Hi guys, I'm a bit lost too.
My phone is a V300S that is Frankensteined to US998 with V300S modem, bootloader unlocked and installed TWRP.
However i also faced the problem of installing Android 10 based roms causing bootloops, I've seen on the Custom ROMs page that i needed the lastest stock Pie blobs, which is what i have currently (30b)
Is this variant using a different way for custom ROMs? Or did i do something entirely wrong on Frankensteining?
Edit: silly me recently saw that i need to convert my V300S to H930, not US998... I guess I'll try that first
Update: well everything went south, now i can't go back to US99830b anymore, stuck at V300s Oreo. I guess I'll start everything over again, but if there are things or procedures i needed to know, please, any help will do
I've been on Page Plus (Verizon MVNO) for a couple of years with this phone. I unlocked the bootloader and rooted it via Frankenstein and WTF methods. I just switched over to Mint (T-Mobile MVNO) and am missing a couple of features on the VS996 rom. I'm also getting incoming calls going straight to voicemail. I'd read that flashing it to US998 could fix it.
How can I flash it over and which stock rom should I use? Can I go straight for US998 Pie or start with Oreo? Can I flash the zips through TWRP or does it have to be through LGUP? I've been wading through a ton of posts for hours and can't seem to find a definitive answer.
What ROM are you coming from? Nougat, Oreo, Pie? That makes a difference...

Yes. For one, on VS996 firmware you don't have LTE band 12, which is very important to T-mobile network. US998 will give you that, plus US998 firmware will handle T-mobile VoLTE. It should also handle that on T-mobile MVNOs.
Do NOT try to flash actual T-mobile firmware onto anything but a true native T-mobile H932. I'm sure you understand that, but reiterating for others.
Instead we will be flashing US998 firmware back onto your VS996 phone.
When you used WTF you had to temporarily flash early Oreo US998 for fastboot flash commands, so you were on US998 at one time. We are just going back to US998, but more recent firmware.
Either flash last Oreo US998 20h or Pie US998 30b. You would use the TWRP flashable zips, NOT KDZ. With the TWRP flashable zips you can flash straight to those.
The Pie US998 firmware is a little wonky. Many people get stuck on the LG logo and then have to go down the rabbit hole of tedious workarounds. I am still on last Oreo 20h US998 for my daily phone, even though I flashed to Pie on a backup phone just to prove it works.
Even though these threads are labelled KDZ, you will also find the TWRP flashable zip versions there side-by-side:
[US998][STOCK][OREO]LG V30 US998 US99820h_00_0318.KDZ
NOTE: You possibly can just flash US998 20h, when going from VS996 later firmware. However, you may need to flash 20e, 20f, 20g and 20h all back-to-back. For the Oreo TWRP flashable zips they were incremental to some degree and just flashing 20h only may not be best case scenario. We figured out 20e, 20f, 20g, 20h was a good combination. I know this is true when going from US998 20a or 20b. I do not know if this is necessary when going from VS996 last Oreo or Pie to US998 20h. Just giving you more information.
[US998][STOCK][PIE]LG V30 US998 US99830b_00_0902.KDZ
If you use this and get stuck on LG logo read ALL of post #6 for various workarounds.
What VS996 firmware are you on? Pie or still Oreo?
Thank you so much!
I have everything working, as it should. I'm getting calls, AND I have wifi calling now. I didn't have it on VS996 after switching to Mint from Page Plus.
I was on VS996 Pie and I had to flash E-H. I first tried just H, but it went into a boot loop that was really fun to get out of because it wouldn't let me power down. I had to wait til it went to the Unlocked Device screen to get into TWRP again.
Now, I have to debloat and install everything again. No biggie. I've done this a million times with my other phones.
Thank you, again.
I hope this can help someone else.
