Dear XDA,
I've rooted my LG-H850 some months ago. After some time i decided to update my phone to a new rom and saw that Nougat finally came out for the LG G5.
Now i'm reading the topic from Fulmics 1.0 and saw the following : '''Just flash in TWRP recovery after performing necessary wipes. Be aware that you have to be on Nougat bootloader, so make sure to have installed official nougat KDZ first.'.
I did some reading around on XDA but is still leaves me with some questions and i hope i can get some information about it.
People are talking about LG Bridge.
I haven't checked this out so far. My phone has TWRP and a custom rom on it.
If it's possible to update my phone, is it safe to do it this way?
Also i've seen people talking about a KDZ file. It has been a while since i rooted my phone and if i remember correctly you needed to use the KDZ to get TWRP on it. Correct me if i'm wrong.
If i install this KDZ file, am i ready to go and flash the Fulmics rom?
And if this is so, where can i find this file?
Sorry for the noobish questions but i reallly want to safely update my phone.
Thank you for reading!
With kind regards,
MarshalSmit

Thank you for your reply. I totally forgot to mention i have an LG-H850. Does this works for the H850 as well?
Anyone that can help me ?
I also have H850. I was rooted on MM. All I did was flash N KDZ with LGUP. Then I falshed TWRP (N version). Then I Flashed SuperSU (N version) from TWRP. For now I'm using rooted LG stock (N). I honestly don't see the point of custom ROM for now...it works great, smooth, battery life is good (approx the same as on MM).
I've done everything you have said and the phone worked perfectly with SU and all.
After that i installed Fulmics on it. After i restarted my phone it gave me an message that the phone encription had failed and that i needed to reset the phone. With my stupid head i pressed on this button.
Currently i'm getting instantly booted to TWRP and that's it.
Did i just fully bricked my phone?
// Starting the phone connected to a charger fixed it for some reason .

I believe it is. I'm honestly to scared to flash the rom that i want .
I accidentally update magisk to the latest one (I totally forgot that it can only run on version 17) and now its stuck on the v30 thinq logo
can anyone help?
Are you able to boot into TWRP by powering off completely then Volume Down + Power till you see the logo then release/re-press Power (keep holding Volume down the entire time, of course)? Or can you get into the stock recovery if that's on the device (can't see how considering Magisk being on it but hey, who knows)?
If not then you could be looking at needing to reflash the entire thing using LGUP and starting clean, at least as far as my experience says. The boot loop you're experiencing isn't magically going to fix itself, so if you can't get into recovery, whether stock or TWRP, there's not much else you can do except potentially start clean.
Could be missing something here but from just what you said it might end up being the only viable solution: a clean flash with LGUP, so be prepared about having to do that, more than likely.

You can run the Magisk 18.0 from WTF thread and even update to 18.1. I've long had Magisk 18 attached to WTF Instructions and recommended in the WTF instructions...
However, Magisk 19.x has issues flashing the stock based TWRP-flashable zips.
It's simple! If u can get to TWRP, then flash magisk uninstaller. Then reboot.

Hmm. I've been using 19 ever since they were released as stable on stock flashable zips. No issues that I've noticed.

The problems only arise if they start with 19. If you were on 18 and update it to 19 there's no problem.

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!

Update : I have KDZ 99820a using LGUP and locked bootloader I'm back to stock is there any issues if I update to the 99830b which is the original software that the phone came with? Can I perform that update via KDZ?

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:

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!

Help!
I've had a verizon V30 I unlocked and rooted via the frankenstein method a few years ago.
I was running out of space recently and did some cursory research about 'my verizon' app and it was pretty large, so I made a titanium backup and then deleted it. Also did this for the basic 'messages' app built in.
Noticed the phone was a little laggy and having some hang issues after that so I rebooted. It's stuck on a Verizon splash screen with a few colorful dots.. seems stuck there.
I've tried clearing the cache and booting into safe mode all with the same result. I really do not want to do a factory reset.
What are my next steps for troubleshooting this or trying to restore that program? Any help is appreciated--I've tried to search a bit but not finding a good first step towards trying to resolve this.
Thanks!

Early on with the verizon V30 roms I found that uninstalling some of the bloatware caused boot loops. From then on I just froze them; doesnt help your space situatuon though...
If no other suggestions, you could try a dirty flash of the ROM you were running (assuming you flashed TWRP zip).
I believe you'll need MyVerizon anyway, as this is what enables VOLTE and VOWIFI on Verizon (for me, at least). So I would not recommend removing it anyway.
Granted, you're past that. I would think that dirty-flashing the ROM should restore it, potentially? That could be one way to get back to running. Another way might be to reload the APK somehow. You might need to use TWRP to do that, unless there's another way to do it from a TiBu backup? If I can help in some way (I'm on VS996) I'm happy to try.
Unless you actually deleted the apps from System, it's almost certain that a Factory Reset will solve it. But I can understand your reluctance.
I'm not sure a dirty flash will help, since the problem is your data partition. You already tried deleting cache (I presume in TWRP).
And I agree that if you could somehow reload the apk, that might do it. Does ADB install work in TWRP, despite no OS? If so, that's worth trying. First pull the apks you removed from System to your computer, then run adb install apk-filename.
But FIRST make a full TWRP data backup of what you have now!
If you have to Factory Reset, you can use TiBu to restore your user apps from that backup. I haven't tried that in years, but I assume TiBu still has this feature.
Fingers crossed for you :fingers-crossed:
And for others who see this: Careful, selective debloating IS possible, but it always starts with a full backup: TWRP if rooted, otherwise LG Backup, (which saves app data and most OS settings).
Thanks all for responses, appreciated so much. In a bit of a pinch as I needed my phone for a backpacking trip last weekend, I just moved forward as best I could on Friday. Generally I tweak my phone enough to unlock/root then let it be. I guess I got greedy/complacent try trying to de-verizonify it and clear some space as much as possible.
Two things
1) Immediate solution, and still seeking some advice:
I used LGUP to flash the Android 9 kdz as an upgrade I think to the phone. Because I had TWRP as my recovery that ran into an encryption error (I subsequently saw this caveat/warning further down in one of ChazzMatt's posts), and due to that was required to wipe/clear everything.
So now I have 'benefits' of Android 9 but no root. However my bootloader is still unlocked.. so I am still seeking advice how I can get Android 9 root. Please don't tell me I have to go back to 8 and do some stuff before going back to 9 with root. I didn't actually see in any guide how to root on 9. But it is possible I missed it/just need to apply same sequence as shown as on the guide for doing so on 8.
I'm on 30c version of PIE and keep getting bugged to install a system update which I keep putting off because I'm leery of that..but I can't freeze the process without root.
Also because I flashed the stock OS, that means I lost the custom recovery, I don't have TWRP anymore (this seems so, but looking for confirmation), right?
2) retrospect, and a question for future reference
After all this I realized like an idiot I had a TWRP backup made in 2018 after I first unlocked and rooted it. Just hanging out on my SD card, which I could have accessed via TWRP before I flashed the KDZ. If I would have restored that it would have re-installed the OS and retained my data. Is that considered a dirty flash though, like it might not have worked or had subsequent problems?
And secondly on the SD card, I found all the 'dank memes' and other downloads I was worried I'd lost, so most of the data loss tragedy :silly: was averted (main pics backup to cloud, learned that lesson after lg g4 hardware bootloop pain).

With unlocked bootloader on Pie, here's how you reinstall TWRP (IF you are on firmware with fastboot flash commands). Yes, I made a standalone post for this -- but if you read it it's basically just Section 6 of WTF Instructions. However, I had to make a standalone post because too many people kept thinking they had to downgrade back to Oreo, etc.
So, you can reinstall TWRP on Pie if you have unlocked bootloader. The problem is you need to fastboot flash commands to do that. VS996 firmware does not have that, which is why VS996 owners have to TEMPORARILY convert to US998 in the first place to unlock bootloader, install TWRP and root. Yes, your bootloader is already unlocked, but on VS996 you don't have the necessary fastboot flash commands to reinstall TWRP.
Thus, you will need to go back to US998 firmware (flashing KDZ via Dev Patched LGUP) to get fastboot flash commands. You can do it the hard way (US998 Pie KDZ) or you can do it the easy way (US998 Oreo KDZ). With already unlocked bootloader, you don't need to go back early Oreo, you can go to last Oreo. I don't recommend flashing US998 Pie for this, as there's too many people who have trouble with US998 Pie (stuck on LG logo, etc). You just need to temporarily get fastboot flash commands, and get TWRP reinstalled.
That post I have linked in the first sentence is for unlocked Bootloader with fastboot flash commands, on any stock firmware (Pie, Oreo, even Nougat if you wanted that for some reason).
Once you reinstall TWRP, then you can go back to VS996 Pie firmware via TWRP flashable zip.
Thanks for your response, now and two years ago.. super appreciated
I only need to get to the point to put the phone in debug mode (with access to fastboot) to get TWRP installed after flashing the recent oreo kdz. After TWRP installed follow your instructions (thanks!) to flash TWRP pie..
I'll probably give it a go this weekend or tomorrow evening, but do you have a recommended link to US998 Oreo kdz? https://androidfilehost.com/?fid=1395089523397933445 is fine?
Whereafter I'll follow your instructions for installing it (using LGUP patched) at: https://forum.xda-developers.com/lg-v30/development/us998-lg-v30-us998-us99820a040330-kdz-t3786337
In the ROM section, go to ChazzMatt's US998 Pie KDZ thread. It also has instructions for rolling back to Oreo. Follow them to the t.
Make sure to use the Pie-compatible LGUP version in there when you roll back, and install it exactly as described in that thread.
His US998 Oreo thread will have a download link for Oreo 20h (the latest Oreo). Otherwise it's easy to find on lg-firmwares.com.
Good luck to you
Ok really that was pretty easy and not bad once I got everything lined up, did it in maybe 30 minutes or less. I'm in Pie with root now and TWRP recovery. Thank you for the help!
Two points:
1) after flashing TWRP, I got some issues when wiping, I was able to flash the VS996 ROM but kept seeing some red "twrp can't mount system" or something like this. It would be a hassle but do I need to go back and reformat/reflash? or do it dirty at least?
2) maybe related to the above, maybe (probably not) not.. and I realize magisk and other avenues might cover it these days but I'm trying to debloat the TWRP flashed VS996 ROM with Titanium Backup.. stuff like NFL and slacker radio, google music.. like I did on Oreo. But Titanium keeps giving me an error about 'can't find the apk' -- Ti says I have root. I have read a bit that Android 10 really packages the apps in there so it's not like you can just remove the ones you want. is this the case for 9 too?
suggestions for alternative tool if Titanium is kind of a dinosaur in that regard?
Thanks
Well done!
1) It's best to use Format Data in TWRP to avoid that mounting error. Unless you are certain you have no mounting problems, I would recommend doing that before spending more time setting up the OS.
2) Before trying to freeze apps with TiBu, see if they can be Disabled in the regular Apps menu. Most of the "optional" bloatware can. Of course make a TWRP backup before freezing anything with TWRP!
Water-, there is already a debloated Verizon 99630c rom out there somewhere, if you would like to try it. I'm on it now.
Sorry, I can't link it. It was made by micromod777. So do a search for him.
I also use tibu, but there is another app (?) out there called migrate that backs everything up. You might look for it and try it. (I did use it a month or so ago myself just to try it - - worked for me).

You're welcome!
See points "f" and "g" of the screenshot. When you were installing TWRP I think you missed the "format data" part... And/or possibly the "reboot recovery" step immediately after.
If you were reading in an app (XDA or Tapatalk) instead of web browser, it's possible that section was truncated and you didn't see it.

hmmm
it's possible.. ..i definitely gave formatting a shot (hence the red errors.) and believe I rebooted to recovery.
Where I'm at now, OS booting/operating flawless (bloat aside) and root verified, can boot back into TWRP no problem...
recommended course of action?

Not a problem at all! Maybe you mistook this post for another, as you'd fairly promptly replied to me through here over the last two weeks! much to my appreciation.
Basically I'm saying when I was doing some of the wipe functions in TWRP before flashing the new OS, and while flashing it, I saw some red mount system error messages.
However my phone is fully functional, I can reboot into TWRP recovery, I'm not noticing any functional issues with it right now.
Can I ignore because functional phone and recovery access = functioning fully! or is there some check I should do or whatnot. I mean I could clear data and start over again but It's been a week+ of customizing and getting it how I like it, kind of a hassle if it's not needed/necessary.
Thanks

Do you have encryption on? TWRP will show a mount error upon start, and prior to the passcode being entered.
Hi,
I tried to upgrade my US998 from Oreo to Pie using LGUP patched. The upgrade process went well until the phone restarted and have this error message:
"Your device has failed a routine safety check and will not boot..."
I did try using LG Bridge to fix = not working
I did try fastboot boot laf.img (using extracted laf from H93031a_00_OPEN_EU_OP_1105) not working.
Any other solution?
Thanks
This Post got recommended to me. I am a Samsung user so my answer will probably be very stupid.
If you have fastboot, why don't you flash a recovery and a custom rom? Ik stupid but it's the only thing that comes to my mind since i don't have a LG phone lol

I'm not sure. Normally I access download mode using volume up and power button. The download mode was there for a sec and then the screen back to
"Your device has failed a routine safety check and will not boot..."
again.
Ah ok so now I understand.
But why don't you unlock your bootloader then if fastboot works? Do you know for sure that TWRP doesn't work?

Unfortunately my LG V30 is US region. The official bootloader site not support my phone. Thanks for your info anyway
I'm not sure why a Samsung user was recommended this post. And no offense to the Samsung user, but the process for unlocking, etc is VERY different for Samsung than it is for LG... so I recommend not worrying about that. Believe me, I know, because I'm researching switching to a Samsung in the future, and the process is very different!
That being said, the best resource here is the WTF thread with the post by ChazzMatt. That post has everything you need in one place.
jacoozie, the error you're getting indicates that you had a non-stock phone when you flashed the KDZ on an unlocked phone. For this reason, it's no surprise you got this error - the phone must be COMPLETELY STOCK for a stock KDZ flash. I'm guessing you had TWRP or something else installed, which is causing this problem. Once you unlock, you cannot just flash things willy nilly... and generally you don't flash with KDZ unless you're trying to change models (aka Frankenstein) or on the way to a custom ROM.
It sounds like you've done some unlocking rooting... if so, I recommend you start over with the WTF thread, read it VERY CAREFULLY and ENTIRELY and then reflash as instructed there. I'm guessing you may need to go back to KDZ Nougat and then work your way forward. If you have questions, ask in that thread... but you shouldn't have any questions as the thread is VERY complete (been updated all the time with very detailed information, so everything is in there).

Thanks for the reply.
I didnt install TWRP or any recovery tools to my phone. My phone bootloader still locked thou.
I have read the WTF thread but the problem is I cant get into my Download mode.
Ok, what steps are you using to try to get into download mode? Presumably turning off the phone, then holding the volume up button and plugging in the USB cable (other end already connected to a Windows computer), correct? If that doesn't work, can you try other USB cables? Sometimes a bad cable could prevent the phone from going into download mode.
