There is something EXTREMELY wrong with my LG V30+ - LG V30 Questions & Answers

(LG V30+ unlocked used with Metro) Everything was working fine last night, I woke up this morning and noticed my alarm never went off (I use 2 just incase so I didn't just miss it) I can't mess with my alarm, I can't change my phone settings, I can't access my gallery, I haven't downloaded anything strange, lookout says I'm clean, I noticed I got pretty close to running out of space but even after making tons of space it's still strange, I've pulled out my sim and sd, restarted the phone without them, no fix If I try to upload an attachment from my gallery it shows an empty gallery, android system says it can't take save screenshots, and I can't download apps, I'm at a total loss. I DO know that all my data is in there, just locked away.

You could try dirty flashing the stock ROM and removing magisk modules( run magisk in core only mode it's in settings)

When you say "unlocked" that means two different things -- "carrier unlocked" or "bootloader unlocked/rooted".
Carrier unlocked we don't really care about for stuff like this. What you were describing could be root app/module conflicting with another.
But you are completely stock.
Have you installed any new apps recently? I know you said nothing "strange" but strange doesn't come in the app title.
Something is corrupted about your phone or something is BLOCKING normal phone functions. If it's not an app you recently installed, then the only solution is to re-set your phone and/or reinstall your firmware.
If you were bootloader unlocked and rooted, you would have the option of restoring a recent system backup you made -- but you said you are not modded.
So...
1) You need to Master Reset your phone -- which will lose all your data. (Master Reset is sort of factory reset, but using the hardware buttons.)
With your device powered off, press and hold the Power button and Volume Down buttons simultaneously for a few seconds.
When the LG logo appears, quickly release and then re-hold the Power button while keep holding the Volume Down button.
Let go of the buttons when the onscreen menu appears.
When you see the option to Delete all user data (including LG and carrier apps) and reset all settings message prompt, press the Volume Down button to highlight Yes.
Then press the Power button to reset the device.
Wait until the reset is complete then reboot your device. If it’s able to boot up successfully, proceed with the initial setup.

2) If that doesn't work, then you need to use Dev Patched LGUP in Refurbish mode to reinstall your stock firmware. (Are you on Oreo US998 or Pie US998?) That will also lose your data.

there has got to be a way to do this without losing all my data...the crazy part is that I can't seem to get the phone to show as a hard drive on my pc when I plug it in.

As I said if you were rooted, there would be another way. You could boot into TWRP and restore a recent backup. Like going back in time.
But the two methods I just noted in my previous post are your choices, I believe. If you functionality doesn't come back after Master Reset, then the you need to reinstall stock firmware using Dev Patched LGUP in Refurbish mode.
Sure, if anyone has any other suggestions, please chime in.

You said you have V30+, but WHICH variant V30+? US998, I assume? But I hate to assume. Are you on Oreo or Pie? If US998 Oreo, which one? 20b, 20d, 20h? Or maybe even still on Nougat 10d?

OK. If you are on older firmware, it might be possible to flash a firmware update in UPDATE mode which would save your data. This UPDATE might fix some stuff that is broken.
The more sure method is REFURBISH mode, but that definitely wipes out your data.
So, answer the questions I have been asking.
US998?
Are you on Nougat, Oreo, or Pie? If Oreo, which letter version?

The problem with getting my exact model number is I'm not sure where to look, not like I can look at my phone info in my settings. :/

I'm gonna look at my newegg order history and see if I can get those details

The only way to carrier unlock LS998 is to convert to carrier unlocked variant. I bet it's now US998 and probably still on 2 year old NOUGAT 10d.
Go to Settings/System/About Phone/Software Info.
You can use Update mode of Dev Patched LGUP and update to Oreo 20h, keeping your data. This will possibly fix your issue.

Dev Patched LGUP should tell you what firmware you're currently on. Program us installed on PC. You put phone into Download mode, attach to PC, before opening the program.
I can tell you more tonight.

How do I get into DL mode, and don't worry, answer whenever, I appreciate it

@ChazzMatt: You deserve even more credit for your helpfulness than you're already getting around here.
@Ace452: You could try LG Bridge on a PC and see if it can back up your phone. It may not if the system is completely messed up, but it's worth a shot. If it works, it can save the contents of Internal Storage to the PC so you have your photos etc. Saving App data is more doubtful given the situation, but still worth a try.
I apologize for wagging a finger, but I would point out that this is why regular backups are a good habit with any computer. Once a failure hits (which it always does, sooner or later) it's usually too late to save the date. In your case, there is a good chance that Google will have backed up some data, which can be restored after factory reset or on another phone.
Good luck to you. You have the best help you could possibly want!

[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!

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.

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.

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!

Three different solutions.
1) Reinstall full image KDZ as "Upgrade". This will keep your data. If that doesn't work...
2) Factory Reset. This will wipe your data, but will clear everything. If that doesn't work...
3) Reinstall full image KDZ in Refurbish mode.
Where do I find KDZ for LG v30+?

No, rooting is not required.
We have KDZ for several variants posted here in this forum. Or you can go to LG-Firmwares.com.
What variant do you have?

Also in Developer Options, try changing all your animation transitions to .5x and turning on GPU Render.

Strange. "Upgrade" option (not Refurbish or Partition DL) should have kept your data if flashing the same region firmware.
As per my previous post.. Upon further investigation I added Home to baterry optimization exclusions and sort of removed the issue.. I'll keep digging into it as it bothers me a lot ?

Hi ,
Having the same issue with my v30 thinQ. It was only a slight delay before but has gotten worse and delay is much longer. The home page does come back but takes a long time, degrading my ability to use the phone. Would I apply the same KDZ upgrade from the same post you mention. I am not a developer but have had my v30 for several years and have my home page just the way I want it and don't want to lose it. I don't have the battery saver feature on.
Thanks

Yes, why wouldn't it? This is the XDA V30 forum.
If you think "ThinQ" is some kind of special V30, it's not. That's just the silly name LG stuck on ALL V30 variants updated past Nougat.
For V30, "ThinQ" just means you are not on original Nougat, but have updated at some point to Oreo or Pie. It was supposed to denote the A.I. camera software that came with Oreo and above. The V30S variants were the first "JOAN" device to get updated to Oreo from the factory, but all V30 eventually got Oreo updates. So ALL V30 are "ThinkQ".
The post-Nougat A.I.ThinQ camera is great, another reason to NOT stay on Nougat, but still a very stupid name. Not even pronounced "ThinK" -- which would sort of make sense for Artificial intelligence, but instead LG actually pronounces it "Thin... Q".
My answer quoted above is for all V30, no matter what stock firmware they are on. You don't say what variant you have (H930DS, VS996, US998, etc), but I would suggest last Oreo (very stable) for your variant or perhaps last Pie -- but not Pie for US998. For US998 I would say stick with US998 20H (last Oreo).

If everything else works except the Home screen, you could also try to just wipe data for the EasyHome app in the Settings/General/Apps & notifications/App Info menu. Worth trying.
If I were you, I would make a backup first using the Settings/General/Backup/Backup & restore menu. Most people overlook this great LG Backup tool, which can backup all app data and most systems and settings data. You can select what to backup and restore.
In case you have to factory reset or flash it clean, you can restore most of your phone data and settings from that backup. Of course save your Internal Storage to a PC or SD card or USB stick before wiping, including that LG Backup file.

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.

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.

Phone not recognized in download mode

I tired a search and the only similar thread i found was someone who was able to boot into twrp. I am not able to do that. over a year ago i rooted my phone. but i haven't had any issues. out comes this stupid update and my phone tried to install it and failed. since then I've had issues so i figured i'd just reset the phone. I go to pull up adb and adb will force my phone to reboot but does not recognize it after its in bootloader mode. Okay weird also will show my phone in adb when i type adb devices, and will force it to reboot to firmware update, but never sees it. Figured I'd start back at square one Load up the patched version of LGUP, it recgnizes my phone when its NOT in bootloader mode, but the second i try it in bootloader it doesn't see my phone. I've tried deleting the adb Lgup the device drivers i've revoked debuggin authorization I just can't think of anyreson other than so messed up firmware that the phone would be doing this

If you did it correctly, then that means you must not TWRP installed. If you had TWRP the button dance would boot to TWRP instead of wiping your phone. I hate doing the button dance as it takes specific timing to hit the buttons correctly.
In all my Guides there's only one scenario where I tell people they have no other choice than to use the button dance. In all others I stress other options.
I also tell people to never take an OTA update if you have TWRP installed.

Yeah I woke up to the "update not installed" nag screen...I know i had twrp installed since it's how i installed magisk, and the VS99630c .zip. Those are still on my SD card. At least after wiping the phone it seems to be behaving properly, but magisk is now gone and being unable to boot into twrp means I can't put it back. It's all good though it's a 3+ year old phone figured if i can't fix it i'll just replace it. Didn't know if anyone had an experience like this with lgup and adb not recognizing the handset in download mode. Seemed like a strange quirk...

Yes, sometimes reinstalling drivers helps. Also trying a different computer.
Your bootloader is still unlocked, but because you are on Verizon firmware it's not giving you the scary warning. To reinstall TWRP and Magisk, using Dev Patched LGUP you would have to temporarily flash back to US998 firmware (Oreo would be best), then use go through Section 6 of the WTF Instructions to install TWRP, reformat internal memory, install Magisk. Then you could re-flash VS996 30C (until a TWRP flashable zip of 30d comes along). You would need to freeze the update files so this doesn't happen again.

Yes i've been trying to just start back over at square one using the patched LGUP, but it doesn't recognize the phone. I've numerous cables and 2 different PC's and no luck yet. I am going to try and buy a new cable though since I just used the ones I've had around the house. Seems odd that the phone is recognized using the cables up until i place it into download mode though. Might try and clean out the ole charging port as well. Again i originally followed the instructions to a T and have had absolutely no issues but noticed i lost voice commands and my sms/mms were messed up, immediately after the failed update. the phone seems to be 100% now with no issues due to the wipe. SO it's not the end of the world if I can't figure it out, but more like a challenge of fixing it
If someone can capture and share that OTA update you received, you can flash it using LGUP in FOTA mode. This often restores a broken Download Mode, even if the system update itself fails due to the phone not being stock and/or lacking stock recovery.
LGUP FOTA mode works inside the OS (with the phone in File Transfer mode) and doesn't require working Download Mode.
Just a thought
Caveat: The purpose of this would ONLY be to fix your Download mode. However there is a risk it might actually mess up your OS (which is currently working). So if it doesn't fix your Download mode, you'll actually be worse off.
I have the exact same issue so you're not alone, I'm trying anything I can think of, lmk if you figure something out. It's weird it sees phone in desktop with phone booted then a glitch in download mode and it never pulls up. I'm due for a new phone anyway, the update slipped thru somehow, lost root and twrp, can't flash. I'll let you know if I figure it out as well. If Chazz don't know how to fix itwe might be out of luck.

I'm due for a new phone anyway, the update slipped thru somehow, lost root and twrp, can't flash. I'll let you know if I figure it out as well. If Chazz don't know how to fix itwe might be out of luck.

Which model do you have, and which ROM are you on?
If you are "somewhat stock", on a model for which we have OTA files, you can force flash those using LGUP FOTA mode. This works inside the OS, doesn't require Download mode, and will often restore Download mode as the first thing -- even if the update itself fails because the phone isn't completely stock.
If you are on T-Mobile H932, we have a separate thread to help restore Download mode using OTA files and LGUP FOTA mode:
https://forum.xda-developers.com/lg-v30/help/h932-url-h932-pie-ota-file-t3991417/page7
And if you are on any model OTHER than
T-mobile H932, and you cannot find an OTA file, you can use the firehose and guidance in the thread linked below to re-flash the laf partition (Download mode).

I have a Verizon on 30c, I would like to make it to 30d, this phone started out as a ls998 sprint model, not that that matters idk. Yah I'm gonna try one of those mentioned routes to fix, I'm out of ideas.

You're in luck then: If you're on Verizon 30c, it *should* offer you a 30d OTA update. And if you accept that, it *should* repair your Download mode as part of the update
The potential risk here is when you're not completely stock, the OTA probably won't complete. That's ok as long as it repairs your Download mode, since then you can re-flash with LGUP. But in case it *doesn't* repair your Download mode, you could theoretically be worse off. I haven't heard of cases where that happened, I'm just pointing out the potential risk.
Good luck to you :fingers-crossed:
Edit: No wait, if you started out as LS998, Verizon won't offer you the OTA. But I believe somebody captured the 30d OTA file and shared it in another thread (about the 30d). If so, you can force flash it with LGUP FOTA mode. Make sure the PC can see the phone as MTP (USB File mode) before attempting this.

No Download Mode - Only Fastboot

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

Is that "Download mode" the same as the Samsung one? How do you NORMALLY access it?

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?
I really want to help but I don't have a LG phone

EDIT: The LG Bootloader unlocking page is "under construction". Guess you have to bring your phone to LG for them to fix this...

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.
