*I flashed a CM12.1 nightly on top of one that was a couple days old, and the new one had all kinds of force closes. This was through CM's internal update function, which sets a recovery script and reboots into recovery to install it (which BTW failed).
So I went into TWRP and flashed the backup I made not a couple hours earlier. But now I have kind of a bootloop. Most of the time, the LG logo shows up, then it just reboots back into recovery. One time it got stuck on the logo, and I was able to see it with ADB but it told me init.sh was missing when I tried to adb shell into it.
I have three backups I tried restoring, which had /boot, /recovery, /system and /data, plus I wiped the Dalvik cache and /cache, but nothing I've tried will kick this thing loose. I've even tried formatting it back to EXT4 from F2FS, and erasing and recreating the partitions in fastboot. It seems like there's a flag somewhere telling it to reboot into recovery, but I can't find anything pertinent online. I'm really at a loss as to how to fix it, and out of ideas now.
Have you tried using the lg support tool to bring the phone back to stock?

Yeah, I was going to edit the OP to say I've also now tried to flash back to stock, using the 20a KDZ and the LG Flash Tool 2014. When it gets to the point where it's actually about to flash, it says "USB is not connected". I have all the latest drivers, and have tried different cords, to no avail. It has been transferring files while connected in TWRP, so I'm not sure what that's about.
What about using the lg support tool to flash stock?
LG Mobile Support Tool is what LG Flash Tool calls to actually flash the ROM (otherwise you have to depend on what LGMST decides to download). It saw the phone the last time I used it, but wouldn't show LP 5.0.2 as being an available update, even though it had been released.
This thread has the instructions I've been working off of, which was posted around the time the ROM was released. It "should" work, it just doesn't. If I'm not mistaken, there may be another tool you can use, but I haven't been able to find it.
There's one other way I suppose I could go about this, but it would be delicate. I could push all the individual IMG files from a ZIP archive I have of the KDZ, but I don't know what all the partition names are, and there are like 10 of them, including laf, aboot, etc. For example, the /data partition is actually named "userdata" when you use fastboot flash.
I didn't know about the difference between the LGMST and Flash Tool.
All I know is that the LGMST was able to download the correct LP ROM for my phone, install it, and get me back to stock after I screwed things up when trying to get root.
i have same problems , here is my solutions
- use SKR tool -> 4 .fix utility -> 5.unbrick ,
if u want go back to stock, try use TOT file to go back JB
cant use kdz way

+Thanks, I have never even heard of that. But I'll give it a try. By any chance were you using F2FS?
Though I am not sure, but I'm leaning towards some kind of hardware failure -- this is a refurbished phone, so there's no telling what it's been through inside. T-Mobile sent another one overnight, which I should have in a few hours, but I still need to clean up this one if it has to go back.

Mine told me I had the latest version, which is peculiar. Was your phone rooted at the time? Because I could understand it refusing in that case: I ran into a soft-brick on a D800 because of an OTA once. Otherwise, I'm not sure why one would work, and the other wouldn't.

The reason I ask is that I had a debate in another thread about using F2FS instead of EXT4 for the filesystem. Most people suggested it's buggy and causes problems, so I wondered if that's what happened here.
When I used lgmst, my phone was giving me boot certification errors. I played around some more with it and then it would only go to download mode.
I connect the phone in download mode and the program downloaded and installed the latest LP rom for my 802 from UAE.

I wish I had a D802 -- it's ubiquitous, and thus has more support on XDA, I think. I'm not sure why T-Mobile chose to have a customized model. Same goes for AT&T, since they both use the same frequencies... and I don't know what the hell Verizon was thinking with those hideous buttons. The only differences I see between most of them is the SAR.
I am not sure that all g2 phones support the same frequencies. My 802 will not connect to LTE in Canada.

Well, they don't, especially Verizon and Sprint being entirely incompatible because of CDMA. I looked it up just now, and while there are several variations of your phone, it actually looks like it has a lot less frequencies than the T-Mobile device. I was under the impression it was the other way around, but I dunno exactly -- yours is supposed to be a D803 up there. It depends on the carrier/region, and which LTE bands they're using. It may be that you get LTE somewhere else eventually.
I don't know why the hell they don't just make the phone with all the bands you expect to encounter on a continent, but I'm sure it has to do with lock-in. Because the SoC should already have that stuff baked in.
I actually have an 802 (International version, unlocked) that I bought off a guy on Kijiji. It was an incredibly cheap price because it had some scratches on the screen which are not very noticeable. Once I applied a tempered glass screen protector, you could only see the scratches from an oblique angle. The guy even included an official LG flip case which wakes and sleeps the phone This phone even has a stock LP ROM.
I love the glass protectors! That gel adhesive just melts on the screen and leaves not a single bubble. And yeah, it gets into scratches and improves them, too. I'll never use film ones again. I've personally never broken a screen, but Gorilla Glass can be scratched under the right conditions. Hey, as long as it's working for you, cheap is always good. HSPA+ isn't anything to sneeze about either -- I've had some amazing speeds on T-Mobile with it, for years now. It's a great fallback for LTE.
Okay, I managed to recover the original phone!
Something in my previous build was triggering the boot loop into recovery. This happened when the CyanogenMod updater tried to flash a new nightly, so there's a possibility it set a flag that kept it looping. But it's also possible Xposed went haywire somehow, and/or a module did. I'm not really sure why it decided to fail like this, when I had been using it without issue.
All my backups did the same thing, yet those builds ran okay when I backed them up. And I don't know why I could see the COM41 port, but not use it -- the drivers were perfect, I went to a lot of trouble to uninstall and replace them. That meant no LGFlashTool, and manual restoration (ye olde commande line).
So, what I did was use fastboot to flash every partition I could get my hands on, not just the ones you can format in TWRP. I used the 20c files from here. You basically do:
fastboot erase aboot
fastboot flash aboot.img
fastboot erase laf
fastboot flash laf.img...etc. Then you format the /system partition, and flash a Cyanogenmod nightly into there. I also flashed the /data partition, but left /data/media alone, which saves the internal storage. Then I erased and flashed /recovery just for good measure.
This is a somewhat specific fix, but maybe if someone else comes across it, it can help.
So was following the guide to root with the Step Bat Files provided by

using the Dirty Santa Guide for Unlocking the Bootloader and Rooting the device. Yes I Already know the H915 is not listed but worth a shot anyway..... to me at least. So after finally going though each step bat file multiple times and it failing several times I finally have TWRP Loaded as the Recovery on the Device I can access the Bootloader however when I check the Bootloader it does say it is locked and fastboot oem-unlock gives me the error remote: unknown command. Note that fastboot oem device-id also gives me the same error. Therefore I can't unlock he Bootloader I can reset the phone through the stock method of holding down the power button and volume down button when booting the phone after resetting it each time It boots me into TWRP I can flash all the files I have tested such as BOOT Images and new system images.... I have been working on this since the guide was posted yesterday and been up since 2 (6 Hours now) trying to get this to work today.... I would like to just get into the phone to access ADB so I can possibly revert to stock or keep trying to root. I can flash anything and wipe anything to the device throughout what I have tested I'm an idiot and did not backup the Stock H915 Files once getting into TWRP..... yes I'm Dumb IK (But I also tried rooting my H915 for a Verizon/ATT Root so what do you expect). thanks again to anyone who can help!

Yep. I was having the same problem with TWRP. The above was the only fix I found and it took me a solid hour to get the button combo just right. If you still have the red triangle like myself, the button combo happens before that pops up. To clarify, so you're not wasting your time like I did. You'll try the button combo listed in the quote as soon as the LG logo pops up. If it goes past that to the red triangle, you missed your shot. Pull the battery and try again.
Also. It should be noted once you get into that separate menu and answer yes twice to wipe the phone. It will throw you back into TWRP. Dont be discouraged! In TWRP go to reboot>system.
Hope this works for you bud!

Sorry, I should have clarified my friend. I have a VS995. Deleted everything without making a backup so now I am running US996 stock deodex rom with konverged kernel.
However if your stuck in a twrp loop, the instructions in the quote is what I'd try first as I seemingly exhausted everything else to no avail. And it turned out to be the easiest of the solutions and the only one that worked haha.

The H915 is flashable to the H918 System Image allowing you to access things like the Bootloader and TWRP I just F**ked mine up.... if your willing to try and get super su on there go for itim sure it is possible to get a root working for it.

my only issue is the cellular signal, in the dirtysanta thread, they mentioned that it worked for the h915, but that the dev was having signal issues. I'm not inclined in this sort of thing so I can't really try until someone on the same carrier can confirm.

this should theoretically work.
I know for Samsung phones that was possible.
I had a Note phone from Rogers, and flashed it with a Galaxy S modem for Wind / Tmobile and it worked to unlock the AWS signal, that was not supposed to be supported officially.
I'm hoping LG phones are similar in that way, in which files / modems / boot can be transplanted from one phone model to another.
I'm just not familiar enough yet with LG phones, first time switching away from Samsung after soooo many years.

I took many steps and got a Working TWRP Recovery and had a bootloader however when i went to flash in the ROM and then reset the phone it failed and I got stuck and had to get the model replaced... However I do know for sure that you can get TWRP and a bootloader working on the H915 using the DirtySanta Method from there is the hard part if your willing to take those steps lol.... MAKE BACKUPS! I have not tried to root my New V20 yet... If I get around to it I will be sure to let you know, some people have confirmed it has rooted but you do need the modem all high risk for the reward lol
I have rooted many phones before without an issue, and during the root process for this phone, everything was going great, I flashed SuperSU zip in TWRP and rebooted, since it was the first boot I expected a decently long wait, after about 25 minutes I followed the guide's instructions for Verizon since it did say some Verizon users were experiencing long first boot times. I took the battery out like it said, put it back in, then proceeded to fastboot boot2.img, like the guide said. After letting it sit for an hour this time, I got the idea that something was obviously wrong. After multiple attempts with no success I tried to fix it myself. So far I have learned that on the fastboot screen it says my bootloader is locked again, even after unlocking it. I have tried flashing TWRP as a recovery, just to at least have a recovery boot, that does not work either unfortunately. So as of right now, all I have is a v20 that has no OS, a locked bootloader, no way of booting recovery, I can fastboot with no ADB, and its virtually a paperweight. If anyone has a solution to at least get back to Stock, I would greatly appreciate it! Thanks!
First off. It will say: Bootloader Unlocked: No
Thats normal. 2nd. you are not bricked. You have TWRP installed. You just need to redo some steps.

In his case we needed to redo from step 3.
I managed to un-brick mines after returning sadly from the Sprint store.
First, get to the boot loader screen and try running thru the steps again, especially step 3. You need to make sure you have TWRP.
Use this link to make sure you can get into the different modes (Download mode, fastboot, etc) http://www.hardreset.info/devices/lg/lg-v20/
Once you can get TWRP to show up,then you are good. In the mean time I downloaded "LS997-deODEXd-signed"
When I got into TWRP, I transferred the file to my phone. Rebooted from TWRP back into TWRP and flashed the ROM.
During my reboots, I do get a message saying my phone is corrupt, blah blahblah, but I just wait a few seconds and it will boot up.
Hope this helps.
I had managed to brick mines only 3 hours after upgrading from my Note 4. It took me from 9pm to almost 2am to get it back up again. I can live with the message about my phone being unbootable until someone comes up with a work thru.
Bricked T-Mobile v20
I have rooted many phones before without an issue, and during the root process for this phone, everything was going great, I flashed SuperSU zip in TWRP and rebooted, since it was flash a new rom on it then i get boot loop with TWRP. so i decide to OEM LOCK again after that everything was stuck on my phone just boot loop with LG so any solutions please help me...... THx u for help me.
Kinda nerve wrecking to read about all these "bricked" phones popping up after trying this method lol.. Perhaps I'll just wait until a more tried and true way comes out...
Dirty Santa root is not for the average user who has a couple of experience in rooting.
You have to at least have background on Hard bricking phones to fully understand what you are getting yourself into
For anyone that isnt on sprint that has "bricked" their phone. There are kdz's that will allow you to reflash back to 'stock". Someone had an issue with the kdz, but it was an easy fix. If you failed the process, it can be restored. Just if it doesnt want to boot, just lock and unlock the bootloader...
If your phone doesnt have a kdz, I know TeamDev is working on a custom kdz for such phones. Don't bug him if it isn't finished as I type this.
Anyone that can't get into TWRP, or has failed the process. Either start back at step 3, or if you have TWRP installed but can't get to it, the manual way to get into TWRP is a pain.
Keep your back cover off and hold the volume down button for ease. Now press the power button and as soon as you see an LG logo, let go and repress the power button. Its tricky.... If you get the corrupted screen, pop your battery out and put it back in quick and repress volume down and power. Usually if Im quick enough the first LG logo will hang a lot longer than usual and that gives me time to enter TWRP. A factory reset screen will pop up. Hit Yes twice.
Please help urgent

I've only rooted 2 phones, this is my 3rd (maybe 4th). I am on Sprint. Instructions worked fine for me. I did have one hiccup, but it was my fault, and I was able to root just fine. I've been running for a few months now.
I have not flashed any custom ROM yet, I'm going to wait for the next major version of Android to come out. The only mods I've done so far are Titanium Backup install so I can remove Sprint crap.

it means dirty santa root got a high posibility rate of bricking a device compared to other root methods for other devices and if you have no experience in bricking phones before then you're screwed if it happens to you
Actually, if you follow the directions, almost none of the problems create a true brick-- which means unrecoverable. For most of the cases, you might get a soft brick, meaning you have to back out, use a KDZ to repair it or reflash something else, or start over from scratch and try again-- but usually (maybe with some help from here) you can pull the phone back into a usable state.
I would hazard to guess for the vast majority the process works fine, maybe with a hiccup, but I've not seen many reports of a truly unrecoverable brick from this method. It's complicated, yes, and you need to be ready to read a LOT to understand what's going on, but it seems pretty difficult to end up with a $700 paperweight with this.
So i have been trying tonroot my sprint lg v20 and everytime i try and go to the phone on mobile terminal to enter id
Then enter the apply patch /system/bin/atd /storage/emulated/0/dirtysanta i get this message and i cant go to step 2 to boot into recovery
Any help would be appreciated: i have a sprint v20 and i wanted to know if i have to flash the stock sprint rom or can i just flash lineage rom following this guide? I have it running on AT&T and i want to keep it on AT&T...
can you please assist
Could you help out, please? I don't believe I have hard bricked my LG V20 H910. However, I have read and tried all of the unbrick info out. It seems my screw up is unique. I completed dirty Santa then went to flash a custom. in the boot between that. I get a black screen and cant do anything even download mode will not come up. My PC does make its usual noises when i connect or disconnect, but my phone does nothing.
Ok, I managed to brick mine too. It's a VS995, it was running stock 1AC. I used the LGUP tool to downgrade it to VS99512A, and then did Dirty Sanata and TWRP. After booting into TWRP I decided to try lineage OS with Android 8.0, I did not make a backup of the Stock ROM, which was very stupid. Lineage OS 15.1 flashed but I had no cell service so I panicked and instead of wiping it in TWRP and using the backup of stock I should have created, I just opened LGUP and tried to downgrade it back to stock VSS99512A. Well LGUP said it worked, but when it went to boot it would hang at the Verizon logo with 4 pastel dots. Device manager could see an ADB device and I could connect to it with ADB. So I did and read the logcat. I could see it was trying to update as part of the rollback, but it appeared that some components from Android 8x could not be "upgraded" to Andoird 7.x. There was a repeated error about failing to update SQLite instance version from 3 to 1.
The one feature that could fix this is if the refurbish function worked with any of the VS995 KDZ files we all have access to. But alas, none work instead we only get the upgrade function... or so I thought. Somewhere in my search for the past 2 weeks I found a modified LGUP https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222
**Please be warned what I did was absolutely ****ing stupid, and it was sheer luck I didn't screw anything up.**
From what I can tell if you only flash ("LGUP Upgrade") the KDZ from the same model it never clears the partition it just adds to it. My problem was there was stuff from lineage OS 15 stuck on one of the partitions that was making the rollback to stock fail because it kept saying it couldn't update the SQLLite DB from 3 to 1. So no "upgrade" within LGUP would work because the upgrade function does not clear internal storage. But the link above is to a version someone modded so you can force a partition update from any KDZ onto the system. So I started playing around with forcing KDZs from other models onto my VS995, and I noticed when using the Partion DL function with non-VS995 KDZ files it would say something about the partition changing. All I can assume is that the partition layout is so different on each model and it forces LGUP to re-partition the storage.
**Again I state for the record this was stupid, and I'm only fortunate it worked.**
I forced Partion DL of H91510d_00_VTR_CA_OP_1110.kdz, then H990N10b_00_OPEN_HK_DS_OP_1017.kdz, then back to VS99512A_06_1114_ARB00.kdz, then when it booted it gave the Verizon hello, and moved on finally but the setting service kept crashing while it was trying to load the Secure Boot screen. So I yanked the battery and went into the boot menu and did the Factory Reset function, and it worked.
Lesson learned, always make a backup and don't be so hasty to use tools that aren't fully functional (LGUP).
Perhaps what I've done may help others, maybe I've found out how to reimage or unbrick our V20s. Or maybe I just got really stupid lucky.
So it was only a matter of time before I managed to hard brick my phone. Wouldn't you know it, I'm with one of the only carriers to not have a KDZ available?! #%^&^!
I was trying to update TWRP, but after flashing the phone went to the red triangle screen, then LG screen, then turned off. When I rebooted it went into what looked like Fastboot, but I cannot get it to return to that state now. I pull the battery, do the factory reset process, then get the red triangle, LG screen, then off. I can get the download screen, but that does me absolutely no good without a usable TOT or KDZ. FML.
What options do I have? I'm on a leased device with no way to restore with LGUP (which in my opinion is utter horse $hit). Last I remember, there was some progress being made on a TOT file, but I can't find the thread anymore. @me2151, @Team DevDigitel, @SaintZ93 -- any help, guys???
:crying:
So assuming you can't get to TWRP, right?
I had something similar to this and just kept trying to reboot recovery. Once rebooted into recovery I was able to plug into a computer and force it into fastboot mode.
Wish I had more stuff to help with.

No TWRP, No fastboot...just red triangles, LG Screen, then darkness, lol. Using the Volume Down/Power method results in the same...red triangle, LG, darkness. If only Sprint would provide a dang KDZ.
No worries though, man. I contacted Sprint tech support and they are sending me a new phone. I just played like I didn't know why it wouldn't boot and they immediately processed an advanced exchange. I should be getting a replacement V20 either tomorrow (hopefully) or Monday at the latest.
I'll probably still hang out in the forums, in case files are needed. But yeah, no more root for this guy.

Follow the directions from beginning to end again, may help you require fast boot and twrp again. If not Ill see if the dirty santa maker will have ideas.

It's ok. I've already got them processing an advanced exchange. It's probably for the best since I want to be able to update OTA again and didn't really see much benefit in rooting at this point. The ROMs I was using were pretty close to stock anyway.

If you run the dirty Santa or should get you back up and running, im speaking from experience. A seeks of formats flashes and wipes through adb.

That would be nice, but I can't get adb anymore. I've tried, but the device is not recognized by adb OR fastboot via the 'devices' command. The only thing I can get is the firmware update screen, but that's useless on Sprint.

Correct, just flashing 7.0 in Uppercut. But Factory Resetting might be needed, Oreo data might be incompatible with Nougat base.

You may want to look into anti-rollback numbers, because if you have one at a certain value, downgrading may brick your phone. I don't remember from the top of my head. Please be cautious and do this at your own risk.
Look for "LGUP 1.14" and "LG Uppercut" on Google and download them. The first search results should be what you're looking for.
Install LGUP first. Once that's done, put your phone in download mode by powering down and then turning it on while holding volume down and the lock button (the fingerprint sensor). Next, connect it to your computer.
Open Uppercut (after extracting it) with administrator privileges. It will open LGUP. Have your KDZ ready somewhere easy to find, like your desktop.
You should have four options that you can tick off, one of which is "REFURBISH". Select it.
At the bottom, you will see a list. Select the first thing on the list and click on the three dots on the right. Select the KDZ. Finally, press start. DO NOT TOUCH YOUR PHONE WHILE IT IS DOWNGRADING! I AM NOT RESPONSIBLE FOR ANYTHING THAT HAPPENS!
Once that's done, and ONLY when it says "finished" on LGUP's interface, your phone should boot at the set up screen.
Incidentally, I was after the exact same thing as the OP, and incidentally, my search led me to do exactly as "fegitoli" suggests: Downloaded Uppercut, downloaded the last 7.0 KDZ (H87011i_00_OPEN_EU_OP_0108.kdz), but then I tried to downgrade using the "Upgrade" option (sounds stupid when written I know). Process seemed to be complete, but since the phone started I get an error saying "Settings crashed, reopen" followed by "Settings keep stopping, close app". On the top left corner it says: "Secure start-up" and the phone is an airplane mode with no control over the notification bar or anything else minus power and volume buttons, so stuck there.
Don't tell me that in 8 years of modding various Android devices this will be my first brick?

Not much I can help you with there. I made the same mistake with my G4 which resulted in a brick similar to yours. Hence, why I specified you use the REFURBISH option.
I'm sure other people in the modding forum can help you out. If nothing works, I'd like to pay my respects for you and your wallet.

Ha! It was close but still my "Brick counter" reads zero The answer lied a couple of posts above in @romcio47 's post: "But Factory Resetting might be needed, Oreo data might be incompatible with Nougat base."
I entered in stock Recovery and did a Factory reset from there, then the phone became again accessible from LGUP so I re-flashed the 7.0 KDZ and this time it booted fine!
Can i downgrade LS993 from android 8 (ZVB) to Nougat?
From today i am a happy Nougat user again for my H870 EU model
I've followed the exact instructions from @fegitoli,and i fortunatelly had the perfect result.
Here i have to mention one detail that probably gave me the desired result..
As it is mentioned in the instructions,i selected the "Refurbish" option,but when i pressed the start button,i got an error notification in LG UP display,saying that my kdz file can not be used for refurbish,so i cancelled the whole process without disconnecting my phone from the pc,but i closed the LG UP and opened Uppercat again.
Probably the "refurbish" option is something like a hard(factory) reset mode for the existing ROM.
Then i choose the "Upgrade" option and started the process again until i got the notification "completed" in LG UP interface.
After the phone started rebooting,i disconnected it from pc,waiting to complete reboot.
When completed reboot,i got an error saying "settings are not complete" and "safe mode start",but giving me the option "reset phone"..
Then i pressed "reset phone" and a second reboot followed..after that,it opened the first set up screen and everything went fine.
BE CAREFUL WHAT YOU DO AT YOUR OWN RISK..
I AM NOT RESPONSIBLE FOR ANY DAMAGE ON YOUR PHONE!!
P.S: Many thanks @fegitoli for his valuable help with his post!

Be sure that if one on a million something was going wrong,i was not intented to blame you..
What is everybody doing with his phone,is on his own responsibility.
After a lot of reading here and in other forums,that a lot of people had problems with bricking their phones,i was prepared for the possibility to brick mine too,but i was decided to take the risk.
Oreo,and especially the last June update,had disappointed me with the battery times,so i didn't have other option than to try the downgrade,and i am really happy that everything went fine.
Maybe more people now can do the same and take the most from this wonderful G6.
Regards!

Very glad to hear that!
Here's a little disclaimer I'd like to add. This should go without saying: YOU are responsible for what YOU do to YOUR phone. If you bricked it because you missed a step, it's not the instructor's fault. If everything is okay but the screen shuts off randomly, it's not the instructor's fault. Please mod responsibly and be prepared for failure, because things don't always work as they should.

Please can you tell me how to return Nougat from oreo. I have LG UP and I have official Nougat H870DSU10f_00_OPEN_HK_DS_OP_0803.kdz firmware downloaded. How to avoid brick and factory reset? Can I just refubrish from LG UP or I will have to do factory reset of the phone and "brick" at first?

I did as described above. I was with Oreo 8.0. I downloaded LG UP with Uppercut, downloaded: H87011i_00_OPEN_EU_OP_0108.kdz, (Nougat factory image) then using Uppercut I selected "Upgrade" and pointed it to the downloaded KDZ. The flashing starting normally without any warnings, completed but then on first boot the phone kept crashing (I guess because Oreo data is not compatible with Nougat base as romcio47 says).
At that point I thought I had a brick because the phone could not complete any action other than crash continuously. Then followed the instructions for booting into Bootloader: (volume down + Power for 10", keep both buttons pressed, when you see the LG logo immediately release and re-tap again the Power while volume is always pressed). There it only gives you one option: "Factory reset", selected YES, rebooted and then phone started normally into the Nougat setup.
You can "upgrade" to 7.0 in lgup but after flash you must manually boot to recovery and do a factory reset. I've done it a lot on my H870

Just got my G6 a week ago and there is considerable scroll lag so I'm trying to get back to stock using LGUP. I am getting "0x81000402 fail tot header antirollback". I am on ARB01 and cannot for the life of me get around this. I've tried LG Flash tool with no luck either.
Any insights??

Simplest way is
Take backup if you want
STEP1: download .KDZ file from https://lg-firmwares.com/lg-h870ds-firmwares/firmwares/
STEP2: LG up from here https://www.filedropper.com/g4
SETP3: In dev option open Enable OEM unlock and USB debugging
STEP4: turn off the device and long press vol up + and connect data cable to PC
SETP5: Open LG up S/W it will show your device then select location of KDZ file go
you are done :good:
By the way why you want to downgrade
