You should read the installation instructions in the KDZ thread, where the TWRP flashable zip is also posted.
There are tips and workarounds clearly posted.

factory data reset is disabled by kill switch lg v30

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.

Did I just brick my Phone?

Ok I just got my ATT V30 , works great but wanted to switch to US998 as ATT hotspot dont work, I try to flash us99820g and LGUP and selecting all the partitions, after click start LGUP told me some partitions will change and I click yes (my bad) and after all the process completed the phone is in a boot loop and all I can see is the Android green robot with an red exclamation and the reboots, is there any way to fix it or I sent $130 to the trash can.
If I keep vol - and power it reboots and I can see LG V30 thinkq logo but then the loop starts again.

No it's not bricked.
But you need to read the Frankenstein instructions. You can't just flash other KDZ willy nilly.
For North America variants (except for T-Mobile H932), you have to use Dev Patched LGUP and flash US998 Nougat, then Master Reset, then US998 Oreo.

[Q] Download Mode issues

So, got my V30 here, Frankensteined H931 to US998, never had basically any issues with it so far. Decided to attempt to install the TWRP flashable US998 30b from John Fawkes and that's when all hell broke loose. But I won't get into all that, here's the primary issue now:
I get Download Mode when I power the V30 off and hold Volume Up + insert USB cable (and I've done this with multiple USB cables as well as multiple USB ports), but I never get a connection to the computer anymore in that mode. Nothing, no connects at all, no sounds to indicate a connection, while the V30 shows it's in Download Mode and is waiting for a connection.
If I power it off back to TWRP (3.2.3.7, just flashed earlier as instructed because of the Pie attempt), I get all the proper connections, sounds, etc, can copy files over to the internal as well as external storage, no issues.
Normally when most people say they can't get into Download Mode it's some issue where the device won't power on into that mode when the USB cable is attached - that's not the case here as stated: it powers on and says Download Mode and waiting for a connection, but regardless of any USB cable or port there's never a connection.
I'm suspecting it's a software issue since obviously on a reboot into TWRP the USB port works exactly as expected.
Any suggestions? Because of this I'm unable to do a clean proper US998 20h KDZ flash or the 30b KDZ flash either so thankfully I did have a backup of my previous 20h Oreo install. Of course, because it's all pooched now that is effectively useless because of course of the encryption and upon restoring the backup it won't boot because of the password crap and forces me to format DATA and start all over again.
/me hates encryption when this BS happens, seriously...
So, any tips or tricks that might get me back to a working connection with Download Mode? Flashing a particular partition or something? I'm basically about to redo it with a clean 20h TWRP flashable here in a bit, not left with many other options now.
Anything is appreciated, thanks...
1) Try flashing US998 20e TWRP-FLASHABLE zip. See if that gets you download mode back.
If not, then
2) Try different LGUP.
______
After you get Download mode back, try these steps. Helpful people been testing this out...
For users with TWRP who get stuck on LG logo.
* Flash Verizon VS996 Nougat Partition DL -- EXCEPT for Recovery partitions, to keep TWRP. Do NOT choose all partitions!
You will probably lose download mode, but you've prepped your phone, corrected any partitions. (This is not just for Verizon users, this is for all North American variants -- except for T-Mobile H932.)
* Flash US99820e TWRP flashable zip to get back Download mode.
* Then REFURBISH to US998 20h KDZ.
* Now flash TWRP recovery again and then flash John's zip US99830b.

See Instructions above. Going to write something up in the US998 thread.
Yah, the 20e thing got download mode working normally meaning when the device went into that mode I'd get the traditional notification from Windows that a USB device was now attached - that's what was missing previously for whatever reason.
So I flashed 20h clean with the dev patched LGUP, no issues with Partition DL because I wanted it truly clean without anything that shouldn't be there, and that meant the factory recovery partition as well.
Then I attempted to flash the 30b KDZ, no joy, just stuck at the LG logo and I've wasted enough time on this now so, I'll just wait till some other point and maybe give it a shot in the near future.
Kinda sucks starting over totally clean but hey, this phone has worked near-perfectly since I got it in May so it'll be fine with a clean fresh start. I'm not even going to install Magisk this time, I can't think of a single reason I even need root anymore but if I do I'll worry about that a later time.

You need to do the VS996 Nougat Partition DL step. It preps the phone.
This is what you need to do:
I have all the steps above. The first 20e flash was just to get Download mode back.

Let me start firstly by saying, thank you ChazzMatt! V30 owners around the globe are incredibly fortunate to have your dedicated write-ups and support for these terrific phones. FWIW, I'm seriously impressed with the level of knowledge and your willingness to deep dive issues with folks... thanks again!
Getting to the topic however; I have the identical issue occurring with my LS998U (V30+) that I just went through the unlock process with yesterday. This morning I TWRP flashed the VS99630c ROM and everything worked A-OK except download mode. Exact same symptoms as br0adband is describing - phone appears to enter download mode as normal (though the initial "LG V30 ThinQ" boot screen appears to have replaced the bootloader warning screen?) but is not initiating the USB port for a connection at all.
Connections are established and work normally in TWRP and when booted into the OS so there appears to be something fundamentally wrong with Pie or the flash method.
I'm 99% confident it's not a PC side issue as there isn't even a connection for LGUP or drivers to fault out on.. I also tried my other US998 phone which is on dotOS and everything worked normally.
I'm about to try the TWRP flashable 20e per ChazzMatt's suggestion and will report back if I have success (or not).

VS996 firmware doesn't have bootloader unlocked warning. Verizon never thought it would ever be unlocked.
While flashing 20e should give you download mode back, to me or seems both of you are sort of missing the point of the preliminary VS996 Nougat Partition DL flash (while omitting the Recovery partitions to keep TWRP)
Maybe in your case you don't need it -- since you made it to the other side of Pie, but that Nougat flash fixes any Partition problems. Just be sure to keep TWRP during that.
You may temporarily lose download mode again
Then TWRP-flashable zip US998 20e fix that.
Then REFURBISH to US998 20h. You'll temporarily lose TWRP at that point.
Re-Install TWRP and the three root files.
Then flash US998 30b TWRP-flashable zip.

While my "missing the point" is entirely possible ChazzMatt, I was under the impression that I was already AT the preliminary Nougat step after having just stepped through the Frankenstein and unlock methods?
My progression through those steps was simply;
Frankenstein per your post here; https://forum.xda-developers.com/lg...ssflashing-t3780969/post76510671#post76510671
Unlock the bootloader, install TWRP et. al. per your directions here ;https://forum.xda-developers.com/showpost.php?p=76584629&postcount=193
Upon completing these steps, Nougat is already installed at which point I figured I was ready to flash VS99630c. What am I missing here... should I have reflashed Nougat?
I didn't have any issues like others are reporting with the upgrade to 30c (TWRP flashed it flawlessly and it booted right up).
It wasn't until I decided I'm not ready for Verizon Pie (tastes gross) and went to step back to US99820h that I realised Download Mode was broken.
Is all of this not just a case of Download Mode being broken in 30c for everyone?

Does Download Mode work for anyone after this step or is TWRP back to a 20 series ROM the only way back to a working LGUP?
Sorry if I'm only confusing things more but I figure I'm not the only one tripping up on this... once I understand it better, I promise I'll step in and help educate other folk
It really is true about ChazzMatt's willingness to help around here.
What I never could understand is why some users, after receiving help AND successfully using it to fix their phones, don't even bother saying thank you. I'll happily spend my daily Thanks quota on helpful posts, even if they have no relevance for me at all. And I see Chazz do the same, every day. Others too, of course. But it seems some people feel being thankful is beneath them. Or something... I just don't understand it.

No, download mode isn't broken for everyone. Most people flash to Pie with no issues and download mode still works. It's when reverting to US998 Download mode seems to go away for a number of poeple (not sure how many and may depend on the LGUP used)
_______
OK, if all you wanted was for Download mode to be restored and you had no problems getting to Pie before that, then ignore what I said.
I thought you were trying to get to Pie and couldn't. In that case the workaround involves flashing Verizon VS996 Nougat -- NOT US998 Nougat like in Frankenstein -- via Partition DL mode except for Recovery partitions. That's a necessary prep stage for Pie. Both people in this thread weren't doing that. OK, so you had good reason. :silly:
THEN going to US998 20e via TWRP flashable zip, which restores Download mode. But if the goal was to get to Pie (yours wasn't) flashing 20e to get Download mode was also step zero. It was also necessary to restore Download mode so you could then flash VS996 Nougat via Partition DL mode (except for Recovery), to then flash back US998 20e TWRP flashable zip AGAIN, to then REFURBISH to US998 20h.
The VS996 Nougat part is important for those people hitting the LG logo wall.

This is good news... thanks for confirming!
I've likely done a few hundred ROM flashes and plenty of roots/unlocks in the past 15-20yrs and this was the first time I had a genuine "Oh crap" moment where a low level mode like Download Mode truly failed.
I was also having trouble getting back into TWRP (Noxx PM refused to work on 30c) which fostered a rapidly growing concern that without TWRP and Download Mode, I was effectively bricked (or at least in for a few hours of work to find a resolution).
I breathed a sigh of relief when attempting a Master Reset led me back to TWRP... I still had options!
Anyhow, it's probably fitting for me to exit this thread on the same subject I entered on by saying thank you again for the information share and willingness to help out :good:
Cheers!

THEN going to US998 20e via TWRP flashable zip, which restores Download mode. But if the goal was to get to Pie (yours wasn't) flashing 20e to get Download mode was also step zero. It was also necessary to restore Download mode so you could then flash VS996 Nougat via Partition DL mode (except for Recovery), to then flash back US998 20e TWRP flashable zip AGAIN, to then REFURBISH to US998 20h.
The VS996 Nougat part is important for those people hitting the LG logo wall.

Losing your download mode has nothing to do with stock.
Why did you lock your bootloader back? You can run stock rooted firmware just fine and have lots of advantages like DTS surround sound stereo.
I don't understand why people lock the bootloader back just because they decide they don't want custom ROMs. The best thing to do is run rooted stock firmware, have everything you want.

Don't get me wrong i like having rooted devices because of the endless possibilities it offers but this time mayor newer games that are coming out they have the ability to detect if you are rooted or if your bootloader has been unlocked and they kick you out of their servers, that's the main reason why i want to go full stock, and I was so afraid to do so because some people are reporting when moving from oreo to pie it creates bootloop and since I had issues when I was rooted and flashed via twrp 99830.zip download mode won't detect the USB cable only when I rolled back with LGUP to oreo downloadode started working and I KDZ oreo to have official recovery and relocked bootloader but I want pie is just I am not sure if I can go up with LGUP to pie using 99830b (which my phone originally came with pie) from 99820b
Could you please help me with the same problem with download mode on h932? I'm on stock pie now. I want to downgrade to nought but my PC not recognize phone in download mode. Thank you.

First try a different USB port, different cable and/or different computer. If you never rooted the phone, there is very little chance that your actual Download Mode got corrupted, and one of the above will most likely solve it (although many doubt it because it sounds too trivial).
Also, make sure you're using the latest Dual Mode Dev patched LGUP from one of ChazzMatt's ROM threads.
Next I would try the Update Recovery mode in LG Bridge (on the Update tab).
Finally, if none of those work, you can try force installing the Pie OTA using LGUP FOTA mode (doesn't require Download Mode). It's described in the thread linked below. Best to read the whole thread for context, it's just a few pages.
[H932][T-MOBILE] URL for the H932 Pie OTA file
https://forum.xda-developers.com/lg-v30/help/h932-url-h932-pie-ota-file-t3991417
Hopefully one of those will work for you. Please report your results, regardless of outcome.
Good luck to you :fingers-crossed:

I tried all things with cabels, PCs and drivers, i'm not sure but as i know LG phone in download mode should be recognized as anything, but in my case i have no any devices in the device manager. I didn't root this phone but i bought it with unlocked bootloader so it is possible that it was rooted. I tried lock bootloader but it didn't helps so i unlocked it again. Now i'm going to try to flash OTA file. Thank you so much for help.

Does Download Mode start on the phone?
Just to make sure: From Power off, press and hold VolUp while plugging in the cable. Then load LGUP. Again make sure you're using the Pie compatible LGUP from one of ChazzMatt's ROM threads.
Otherwise I'd try LG Bridge next.
As for force installing the Pie update with LGUP FOTA (the thread I linked) we've only had one confirmed case of it fixing Download Mode so far, although not many tried it yet. On Oreo we had many users confirming it, but Pie is different.
I should add that if you have working Pie, but just would like to roll back, there is a risk that the FOTA will mess up what you have. So if it doesn't fix your Download Mode, you could be worse of. Just a heads-up

Actually the main problem is that phone doesn't recognize by PC when download mode is on the screen. I have tried to use lg bridge to recover, but anyway it reboots my phone and then my phone doesn't recognize. Now i'm trying to solve lg up error with FOTA update, it looks like wrong dll file. I'll keep you up to date.
Thank you!

Got it! Thank you for the update.
Completely uninstall LGUP and remove all folders of it. Then install the Dual Mode LGUP from ChazzMatt's H932 ROM thread linked below, using his exact installation steps. That's important: LGUP isn't just LGUP!

Are you even reading the installation notes in the US998 KDZ Pie thread?
Instead you open up a new thread?
If you have read the workaround instructions and you don't like them, opening a new thread won't help.
sry I don't read your post till the end

I think i bricked my lgv30 trying to root it. please help me.

I was trying to unlock the bootloader and root my lg v30 (h931) or at&t v30 using this method https://forum.xda-developers.com/showpost.php?p=76584629&postcount=193
I used this method to try to get back to android 8 to root: https://forum.xda-developers.com/lg...ssflashing-t3780969/post76510671#post76510671
I used this android nougat version: https://lg-firmwares.com/downloads-file/13784/US99810d_01_0411\
and used the duel patched dev version, I can't find a link I have like 8 million tabs open right now.
What happened:
I was following everything in that guide exactly and got the the point of flashing my phone with android nougat. Everything seemed to be working find and it said it was completed successfully, now my phone isn't detected by my computer at all and my phone will not power on. LG doesn't have a recovery or fastboot mode on the v30 but normall the shortcut to it is volume down and power button and when I do that the lg v30 splash screen comes up and keeps booting over and over. If I try to boot any other way its just completely black and comes up with a not connected screen for like a frame and then goes to black again. there is also a picture but I can't make it out in the one frame It is on screen.
I know I was an idiot for thinking I could root my phone and I am really really regretting it now but if anyone has any ideas I literally will try anything at this point. Thank you so much.
I just found the think on master reset and now I am on android 7.1.2 working. I guess I will try and continue? this has been an emotional rollercoaster

Just read the instructions carefully in web browser. Not an app.
Yes, Master Reset is clearly in the Frankenstein instructions.

yes sorry, actually im having a new issue that I can't find a solution for anywhere. I followed all the instructions for installing havoc on my lg v30 but it has been at a white spilling loading wheel for about an hour now. I know the first build can take a while but this seems a little extreme
edit, I just ran adb bootloader recovery and now im in TWRP. not sure why that didn't work last time but it worked!

Since you have a former AT&T H931 you did all the extra prep steps necessary to install LOS custom ROM for that model?
V30 CUSTOM ROMs FAQ
https://forum.xda-developers.com/showpost.php?p=79459374&postcount=2
See question number 3 of the custom ROM FAQ. H931 and H933 need a lot of extra steps to run custom ROM.
That FAQ is linked in the WTF Instructions thread.

I messed up, I totally missed that im really sorry. I have a problem then. I can send adb commands to my device but once I do that it goes away from being an adb device and I can't send the fastboot command to boot into TWRP, also in any of the states I can't get it to be recognized by lgup right now. what do I do? im really sorry

sorry for another ping but do I flash it with this rom in twrp to then flash my next rom? https://forum.xda-developers.com/lg-v30/development/rom-fw-lg-v30-joan-us998-30b-twrp-t3973811
the tutorial you linked doesn't have a link to a rom that I can see, really sorry
edit: I flashed it and my phone has the lg logo on it, im going to let it boot for a while, but im worried about ending up in the same place I as stuck in before.

I think I really messed up. so the rom in the the post didn't work either so I tried to do a master reset and now I am stuck at the splash screen with that lg logo staring back at me for all eternity. all I can do is enter the master reset menu now but it doesn't do anything. my computer won't see my phone as an adb device right now and I can't enter download mode. the lg tool detects my phone but I can't select it because it is an unknown device. am I just screwed?

Have you tried entering Download mode manually before opening LGUP?
1) Go into download mode (power off completely, then hold volume up button while plugging in USB cable)
2) open patched LGUP and KDZ via REFURBISH. At this point, you would flash US998 Oreo 20h KDZ instead of trying to flash US998 30b Pie. After you recover your phone to 20h Oreo, then you can take another run at US998 Pie if you wish.
3) IF your bootloader is unlocked, it will remain unlocked. However, you will lose TWRP, since you are flashing the full KDZ.
At that point, you will then go through Section 6 of the WTF instructions again to reintall TWRP and root.
