hello guys sorry for my english...i recently unlocked the booloader of my v30 h930, but when i try to enter twrp recovery after flashing the image via fastboot comands,i found this frustrating message "factory data reset is disabled by kill switch"...is there any thing to do ?? thanks again
Odd. Did you flash the twrp image, and then boot the image? as per the WTF instructions?
What command, specifically, are you entering, and then getting this message?
Sounds like twrp didn't install. Make sure you go through all the steps from WTF correctly

Normally we only see that on U.S. T-Mobile H932 which has crappy McAfee installed. Has to be uninstalled before factory reset or you get that error message. Do you have something like that installed?

Personally I have never seen that McAfee stuff on my H932, but maybe it's something you have to deliberately install first.
But we have had others report about this error. As I have posted before, I think it is just "something" (McAfee or whatever) trying to save you from wiping the phone in a way that would trigger Android Factory Reset Protection: The entire point of FRP is to render the phone useless to anyone but the legitimate owner, in case it is wiped from outside the OS while an account is active in the OS. That is a sensible protection. I always wondered why LGs Master Reset (using the buttons) doesn't warn about this before proceeding with its wipe.
But if indeed the error reported by OP is caused by such "protection against unintended triggering of FRP" then the solution should be to remove the Google account in the OS before performing any actions that would wipe the phone outside the OS (LGUP, Master Reset, TWRP etc). Alternatively, perform a Factory Reset from inside the OS first, which also will remove the account in a way that doesn't trigger FRP.
Arguably, this should be mentioned in the various root/WTF/Frankenstein guides, since FRP can have unintended consequences, say in case a user flashes the phone back to stock before selling it or sending it in for repair, and doesn't remove his/her account first. In that case the phone will (or should) demand that the same account be entered on first boot -- and the new owner or repair center would be stuck.
But maybe LGUP Refurbish mode clears FRP, and that's why we don't get more complaints about it...
I apologize if this turns out to be completely unrelated to the error reported by OP
Don't worry I've been through this problem and solution ia simple.
-Boot the phone in normal.
-Plug in the usb cable in your phone and connect to the computer.
-Then type "adb reboot bootloader". When u boot into fastbooot then type "fasboot boot recovery or whatever u named the file.
-Then u will boot into twrp.
I was sold a refurbished v30 off Amazon that had this kill switch enabled also when trying to go into TWRP. I had to return it because it might have been stolen.

I bought a V30 on ebay, is a LS998 Frankenstein, the problem is that the installed ROM is the AS998 and not the US998, it has the kill switch problem. Some way to solve it? I can not access fastboot and I can not install the ROM US998 from LGUP. I tried installing the KDZ US998 from LG UP with Partition UP option but it does not boot. Some way to return to the LS998 ROM?

There are no public LS998 KDZ available.
Which US998 KDZ did you try? If you read the Frankenstein instructions you need to start with US998 Nougat first.
Yes, of the North America V30 variants, only US998 has full fastboot flash commands.

The phone came with the ROM AS99820b (Oreo) :crying:, try to install US99810d and US99820b KDZ. Only the Partition DL option works in the LGUP application, but the phone not boot. The other options show Error: 0x4, Not support cross model download AS998 to US998 . Do you know any way to jump to the US ROM?

I ran across this before where some dealer probably used Octopus box to convert LS998 to AS998 and the new owner couldn't then convert to anything else...
All I can suggest is you try Board DL or Refurbish mode.
Is wiping the system partition the same thing as factory data reset? Will that trigger ye' old kill switch?
I ask, because I've run into the cross-flash warning once before while trying to flash US998 while on VZ996. To get rid of that message, I simply wiped my system partition in TWRP and was then able to use LGUP with the US998 KDZ.
So if you can wipe your system partition, then maybe it will get you to a spot where you can kdz?
I got it!
After many attempts, use a LGUP that I found in the LG G7 forum, the difference is that it was from CLI, restore the KDZ Nougat, when restarting appeared a screen with the android doll and the text without command. The next step was not clear, I pressed all the buttons with different convincing. The phone restarted several times and remained in the same window, in one of those attempts I went to the LG logo and to the initial configuration, the phone was blocked by google. Surely this is the reason why the seller installed the ROM AS998.
Turn off the phone and from LGUP update to the Oreo version. Again the error of blocking by google. On YouTube I found a tutorial to bypass this step. Now I am in the US99820b version. I followed the steps to unlock the bootloader, I had a problem with the USB cable, I must use a good quality cable. The problem of the message "factory data reset is disabled by kill switch" continues, but I can enter TWRP from fastboot.
I will try to install a ROM from TWRP and see if the message disappears.

You can also enter TWRP using the Recovery Reboot app I recommend in the WTF instructions.
US998 20B is old (but necessary for bootloader unlock). You should update to US998 20H. Download 20E, 20F, 20G, 20H and dirty flash back-to-back, using TWRP auto queue function -- with flashing Magisk last.

NO. You need to be on newest firmware before flashing any AOSP/Lineage ROMs due to recent changes. That's where people mess up. They try to go from old Oreo or even Nougat (H932) firmware to custom ROMs. You need foundation of newest firmware. Read post #2 of this sticky:
https://forum.xda-developers.com/lg-v30/how-to/root-v30-t3927154
A whole lot of recent posts in Lineage are about people not updating their stock firmware first.

You can flash stock rom by using lg up and kdz. Make sure you use the correct kdz file for it.
Keep in mind, KDZ flash will erase your data, so be aware of that.

Yep. If you can get some kind soul on here to extract the stock recovery and turn it into a flashable zip, then you can download it, boot to TWRP, flash it, and viola -- stock recovery.
It doesn't matter what model recovery is from -- they are all the same with the EXCEPTION of the H932. If you have an H932, you must use the H932 recovery. You won't brick your phone, but you will be flashing a KDZ if you ever want to take OTAs again. Also, if you don't have an H932, do not use the H932 recovery -- same outcome.
EDIT: if your phone is rooted, you will not be able to take OTAs (the hash check will fail). So, if it is rooted, you need to unroot it (install Magisk manager) before flashing the stock recovery and taking OTAs.

Ironic you wish to remove TWRP from your phone when for several months that's what we would have given large sums of money to have. Finally in May 2018, the WTF exploit allowed us to do that. You can root your phone, since you have TWRP and install recent TWRP-flashable zip based on stock firmware.
But if you wish to return for full stock without TWRP custom recovery, you will need to use LGUP to flash stock KDZ. And yes that requires a PC.

I'll have to let one of the Korean users answer that. I'm not an expert on the Korean models. They have to do extra step to get TWRP, root and get radio back. So if your phone works and has TWRP then at over point in was rooted with Magisk.

If you are going to keep TWRP then I won't bother, but if you want to go back to stock let me know and it just so happens I have that KDZ sitting in my archives so I don't even need to wait 40 years for lg-firmwares.com to download
Just ping me and I can make you a flashable zip that will take your phone back to stock without having to flash a KDZ.
Again, I am not going to bother right now since it sounds like you may actually want to keep your phone as is.

Sorry -- I just haven't had the time -- and it doesn't even take that long. I have a few minutes right now, let me see if I can throw something together for you.
Keep in mind, that I have no way of testing it. It won't brick your phone, but I might have a typo and it will just fail (I have a tendency to have typos ;P ).
If that happens, you will just have to tell me where it is failing, and I will fix it. *crosses fingers that I have no typos*
EDIT: I am not going to do something half assed. I am grabbing the latest firmware available on lg-firmwares (V300K21r) and going to make a FULL zip.
As long as you don't wipe data, even if you are on a lower version, you should be able to flash it and keep your data. I will flash all the partitions that usually get flashed when using a KDZ.
I should have it up in about an hour.....
EDIT2: It is up -- https://www.androidfilehost.com/?w=files&flid=286970
Download and flash that in TWRP. Wipe cache / dalvik. Reboot and you will be fully stock. Again, you should only lose your data if you factory reset or wipe / format data.
Enjoy,

Hi guys!
At this kind of bad time, I got my hands on a weird Japan variant of V30+, meaning that it came with some weird Japanese baseband, IMEIs, modems or whatever. As already seen in xda threads, someone has succeeded in breaking their LGV35... And I surely just in no way want that also happens to me.
So would someone who has successfully flashed any custom ROMs on their LGV35 be kind enough to help me out? Many thanks for any helping hand! I'm willing to install Lineage OS while maintaining the normal SIM functions.
If I ever find any working solutions I would share it here so as to help anyone that comes after me.
For failures that already happened or anyone confused by the weirdo names plz take a look at this thread: https://forum.xda-developers.com/lg-v30/help/lg-v35-isai-japanese-lg-v30-modem-t3966962
Guessing from my former experiences fighting with these Japan variant of Samsung phones, we need to at least back up the original, that meaning, the working EFS partition in TWRP. But as for LG phones, that might just be impossible: You need to flash US998 firmware, or don't I?
Possible solutions found! Guys, I ain't no Fermat who leaves others' a** kicked. I found it on some Chinese forum and I just need to test it out--don't want to misguide anyone else.

Finally, I had time to get my hands on the phone. I'm not as $$y as him tho. I've been trying the method you provided to convert LGV35 to US998, only after which could I proceed. However, I am aware that "master reset" was unable to stop the repeating bootup-reboot procedure. After flashing US998 10D, in LGUP, the phone is still recognized as LGV35 instead of US998. As a result, "upgrading" to US99820a says the wrong device. I had to use DL partitions again. Well, it still loops under that circumstance. Still working on it now.
Updates: Conversion seems successful, LGUP recognize it as "US99820a" now. Dunno if I could ever stop that boot loop or not. If impossible, maybe I had to attempt skipping it then.
There really isn't anything I might do due to that constantly rebooting. In that master resetting, the erasing image does appear, but it doe not help with the boot looping. It is okay for me. The all but one thing that I learned in my long-struggling with android devices, from as early as 2012 to 2020, that it is super normal if things went wrong. You just need to give it more shots, till you finally succeed or simply dump it somewhere.
Finally, I found the way to stabilize OS on the LG LGV35 isai variant. Read accompanied by this song over here if you are a jazz fan just like me: https://www.youtube.com/watch?v=HsM_VmN6ytk
The method is simple:
1, Partition Download US998 10d
2, Partition Download US998 20a
3, PD H930 20j
4, PD US998 10d
5, Refurbish US998 10d

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.

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.
At the most, all you would need
Thanks for the reply. I'm having difficulty getting LGUP to run. I get a 'LGUP can't load the model' I got the file from download LG dualmode. Any suggestions? I'm just trying to load Verizon stock on here, no root. Thanks.

I'm wondering the same as charulo316, but my v30+ is already running pie, but for the unlocked and I want to switch to the Verizon one, do I need to downgrade to Oreo and then back the the Verizon pie version??

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.
tried all. After a few restarts, now get a "DLL for us99810b is invalid. Please install valid DLL package (*.msi) for the model". I've uninstalled and reinstalled a few times, deleted the folder, moved cable around, tried new cable. This is the furthest i've gotten now.
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.

So you Frankensteined to US998, then unlocked the bootloader via WTF exploit. What variant did you start with?

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:
ChazzMatt said:
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.

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.

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).

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?

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
