I can get into download mode, but have a secure boot error and cant use ADB or fastboot. I've been reading every thread I can find.
I tried the LG tool, it never downloads the firmware, just hangs at 12%. Tried different drivers etc. Let it run overnight just in case it was a slow download - nada.
Tried the LG tool by entering the imei number first, but the tool reports a low battery and won't load the firmware. Phone is fully charged, i assume that battery level reporting is not working correctly.
Tried to load the kdz with the R&D tool, it errors out at 49%.
Tried to do the offline process with shttp from the unbrick any phone thread. It uses an older version of the LG tool and won't recognize that the phone is plugged in. If i install the newer tool that sees the phone, the process crashes the tool.
it all started when i tried to flash twrp and used the one for a different model g2. Dumb, I know. this is my first time soft-bricking a device.
Can anyone please point me in another direction?
UPDATE: phone was reporting that it was an 802. Downloaded and flashed an 802 kdz file and the phone booted! First time it was able to get past 49%. Nothing really works on the phone, but now i'm able to use the LG Mobile support tool to flash the correct firmware. The program is downloading the sofware now.
When you say LG tool I'm assuming you're talking about the official program you can download from their site?
I have the Verizon G2 and promptly erased everything on it the first night I got it.. Don't flash / wipe files at 4 AM when you've been up all day and night.
Anyway this thread http://forum.xda-developers.com/showthread.php?t=2432476 really saved my rear. Maybe the T-Mobile version will work to get yours back to stock.

works at the start and hangs at 49%. There is one bit that needs to be switched and this would work.
okay, looks like the phone is reporting that it is a d802 from my first f'd up flash. I think this may be causing the problems with flashing the 801 kdz.
Can i flash an 802 kdz onto an 801? then possibly later go back to 801?
Hi, I followed the DirtySanta tutorial, used the US996 DeODEXed Rom. I knew this was a possibility but thought that I could get back to stock using the KDZ, unfortunately my phone is now seen as US996. I've tried modifying both the build.prop, and KDZ but I still can't get LGUP to flash back to stock. Is there anything I can do?
Service Unavailable is probably due the frequency signal issue.
Remember that Wind runs in AWS bands, while the US996 runs on regular bands (Bell, Rogers, Telus)
I'm sure the phone works fine if you use a Rogers SIM on it.
so, the trouble / solution is figuring out how to flash back the Tmobile / Wind modem back into the phone.
also set the phone to use the proper AWS bands 1700 / 2100, or the new LTE band 66

T-Mobile H918 supports LTE Band 66, try and flash a H918 ROM maybe? Or access the hidden menu and enable AWS, but you'll lose LTE and only have 4G that way.
See here to access the hidden menu but change 915 in the command to 996 or the model the phone is showing as.
https://forum.xda-developers.com/v20/how-to/access-hidden-menu-h915-t3515098
Edit: Let me know if it works, and you get LTE back (not just 4G) I really want to know to root my H915 as well. You used the [LS997|VS995|H910|F800L] DirtySanta Bootloader unlock and Root guide by me2151, right?
Second edit: If you're going to try to flash an H918 ROM I'd strongly suggest you flash an H918 kernel that is suggested in the dirty santa thread, I think the Konverged is what people are using. No hard evidence either way flashing an H918 ROM would work but it may not as the boot image is a 996.
Thanks guys. I flashed the Konverged kernel earlier, it helped crash-wise but nothing on the signal end. Last night I extracted the files from the H91510e kdz and tried to flash the modem that was included but that hasn't helped, I want to try the CDMATool but it isn't recognising my account so I'll wait for a bit. I tried to use the hidden menu but it doesn't seem to do work on this firmware unfortunately.

Try this, make sure USB Debugging is enabled. Turn off phone. Remove the battery. Put battery back in. Hold the volume up button and plug in USB cable. It may boot into download mode or it may boot into the dirty santa corrupt screen. If it does boot into the corrupt screen , let go of up button, press the power button then IMMEDIATELY press the volume up button. Either way you should be in download mode. You want download mode, not fastboot. Make sure LGMobileDriver_WHQL_Ver_4.1.1.exe drivers are installed.
Download LG Support Tool. http://www.mylgphones.com/lg-software-tools-download the 'Download and install LGMobileSupportTool.exe' link. Install and run it. If you've already installed the drivers hit cancel when they go to install.
Then go to 'Options' 'Upgrade Recovery' Make sure you have the IMEI number from under the battery and put it in no dashes or spaces. It should download and install the firmware if you've done the tap 'About Phone' 'Developer Options' 'Enable USB Debugging' but I'm sure you know this.
If all goes well you should be back on stock firmware.
Hope it works, it should but I'm not 100% sure.
The good news is that it recognized my phone as H915, but unfortunately half way through the setup it through a weird error. Part of me is thinking of restoring my twrp backup and trying uppercut again. I'm hoping that will get the program to see my phone correctly.
EDIT: I tried the KDZ installer again, without trying to restore the TWRP backup and my phone is back to stock and getting a signal. Thanks again to the both of you.

What I suggested worked without the TWRP backup? Or another way?
your best bet is to somehow find a way to install the stock rom through TWRP then you can install the KDZ. Cause I had the same issue as you, i have a Verizon V20 with the US996 rom and it wouldnt let me flash the verizon KDZ until I installed NotSoStock rom thats based on the Stock Verizon Rom
EDIT: Just saw you got back to Stock. Disregard this lol

I didn't use the TWRP backup at all in the end. Your method didn't fully install, but it made the phone see itself as an H915 again which allowed uppercut/LGUP to install the KDZ so it was a big help
Congrats! on the recovery, this is a good reference thread for anyone trying to recover from a bad root, and needs to get back to stock.

Are you saying you have a rooted 915 with everything working?
guess not lol
I am having the same issue with an h910, but the service only works sometimes. Many times it is searching (and draining the battery in the process), but sometimes it will get service and be OK. Quite frustrating, and no way to revert because no kdz available. Anyone else with h910 having this problem?
Hi,
I'm not sure if I'm off topic here or not. I have an LG V20 H910-10c (Nougat 7.0) and I am having an issue with a Service not working after using DirtySanta to Root my phone and I am praying that someone can help me out with. I have already tried a Factory Wipe/Reset and Wipe Dalvik/ART & Cache and have Formatted Data to remove Encryption, etc..
Timeline: The phone worked fine in all aspects before Rooting it.
After Rooting it, I had this issue.
I then tried a Factory Reset and got stuck in a TWRP Bootloop.
I fixed the Bootloop issue with a Reset (Yes then Yes).
The issue is still there.
ISSUE: When I boot into Android, I get the following message;
"LGSmartcardService has stopped"
.....and I cannot use my External SD Card (TWRP sees it fine, I Flashed SuperSU from it).
I have Googled my brains out and simply cannot find any suggestions, except to perform a Factory Reset, which I did and that's what put me into the Bootloop and I reset the way you said and now it boots up okay, except that error message is still there.
I have not put any apps on the phone or anything. It's factory fresh (except for Rooting it).
I hope I'm not violating any rules by posting this, but the page I used to Root it has a REAL SMALL downloadable file called "V20-Root.zip" that contains everything, including the Batch files with the steps that they perform in them. I did NOT use the ROM, as that's ONLY for Sprint users and my phone is an AT&T model (Unlocked and my Carrier is MetroPCS). But I put it here, just in case someone wishes to bless me by taking a look and seeing if there's something to note. I am not a coder by any means. I do understand some basics, but I couldn't see anything that would cause this sort of problem. I did NOT install the ROM listed, because it's for Sprint users ONLY and I have an AT&T (Unlocked, using MetroPCS) H910. Here's the link to the page:
https://tinyurl.com/yacdendm
I really need my Ext SD Card to be seen! I use it extensively and it would be a real hindrance not to have it! Plus this is my ONLY phone (no landline) and I am disabled and must run everything, including my home network and laptop, etc. from it and I need its space for things I have to have available on my phone to do things that I need to do, so any help would be appreciated GREATLY!
I do need to be Rooted, so going back to factory with whatever Mpdel # ROM an LG Tool sees me as might make me unable to Root again.
Please Help Me and Thank You!

[H918] Successful root/fastboot unlock from 10J -> No roms are flashed successfully
Hi folks, wanted to share my current state of affairs with trying (and failing) to install a new rom on my LG V2O. Here's the order of events
Received brand new sealed-in-box LG V20 from T-Mobile from a third party seller that came in firmware 10J
Followed all directions to successfully perform dirtycow unlock
Installed TWRP (3.0.2-1)
Backed up, but mistakenly deleted the backup after trying to install Megarom in an attempt to do a clean flash
.zip flashed correctly, but hits boot loop upon reaching LG screen (even after waiting 20+ minutes on first boot). T-mobile screen never pops up
Can access TWRP still and ADB commands
Basically now, I've tried looking at as many H918 rom threads as I could but every single rom I try either: never completes flashing OR if it does complete flashing, the device never boots (either bootloop or stuck on the LG screen). I've never seen the device get past the LG screen for any reason. I am desperate for help on this matter as I have royally screwed up trying to provide a nice gift for my partner but was apparently way in over my head with trying to get a fresh rom on this thing.
Can anyone provide assistance as to how I can roll back to a stock rom? I'd be willing to give up root/recovery. All of this was spawned from wanting to be able to unlock the carrier but I have decided I'll just pay for the sim-unlock service if I can get this back to stock. Would be willing to provide some PayPal cash for someone who can help me out with this matter.
Flash to 10j kdz firmware located in the thread with all the firmwares. You`ll need lgup to flash it.

https://forum.xda-developers.com/v20/how-to/t-mobile-lgv20-h91810j-kdz-t3540747
I got LS997 that was not completely unlocked (Sprint support confirms unlock status but phone did not receive unlock command, and i got no sim card and no previous owners name to re-initiate ota-unlocking process)
First thing i did - i used pathed LGUP and dirtysanta rooted my phone.
Suggested 995 kdz rom was vibrating like crazy (as described in dirtysanta guide) but i got root and started experimenting further.
Than i flashed rootable 996 kdz, rooted, had no vibration problem but got static boot issue, ok, installed mk2000 kernel, no static - all good but still not enough.
LOS16 = gsm/lte unlocked but battery was drained in 5 hours with screen turned off and no camera, got back to 996, rooted, super rom, all good but LTE not operating for some reason. Really enjoyed stock functionality (camera, seconds screen) and decided to get back to stock system.
HOWTO: Root LS997 up to ZV7, did it all, started flashing available 'stockish' roms one by one [this, and this], so there goes bad stuff.
At this moment i was still being able to boot into twrp, so i didn't really notice that phone was bricked, those stockish systems was just hanging in LG logo for hours without any progress. ok, found another one stock ls997 rom in dirtysanta root post, flashed it - and nothing, phone still stuck at lg logo.
LGUP flashing routine that was always helping me recover, now if fully completes partition_dl process but results are the same - lg logo for hours without anything happening, except vibrator motor starting to work on power up on Verizon firmware version and no vibro on 996 variant (as it sould):
996 kdz - stuck on logo
996 kdz- stuck on logo
flashing everything i got from lg-firmwares.com:
US99610g_00_1216 - stuck on logo
US99610f_00_1205 - stuck on logo
US99620f_00_1120 android 8.0 - stuck on logo
VS99512A_06_1114_ARB00 - stuck on logo
download couple more variants and still nothing, phone stucking in lg logo
so how badly i bricked it? is there any method of recovering that i am not aware of?
There is an older thread on returning the LS997 back to stock that may help.

Yeah, thanks, been there.
Unfortunately i'm not meeting 2 of 3 prerequisites:
- Your device needs to be able to boot into TWRP and fastboot mode
- You need access to a computer to run ADB commands to the phone
There are no more twrp presents on device because of kdz uploads from LGUP, i was thinking that it was recovery and aboot partitions that was messing up my system.
And there is no bootable system on device to turn on usb debbuging to run ADB commands as only thing i get is boot logo, fastboot are also locked to 995 or 996 (whatever version i've uploaded last from LGUP, and they are not unlockable because LG recognizes original LS997 hardware identification and refuses to give me unlock.img.
As i get it - the only thing that can tinker with my device is something that can get same hardware access as LGUP (laf is still operational or idk, maybe not, but it should be getting everything up and running but that is not the case anymore for some reason)
So you are saying that LGUP can still see the phone but ADB can't. Did you by any chance do a full system dump of the phone on LGUP before the whole DirtySanta procedure in the beginning? I wonder if those files can help getting things back on track. Not sure if they are device-specific, but I did make a dump of my own LS997, so if you think there's something useful there, let me know, and I can upload the files somewhere.

Yes i did full LGUP backup at first system state, but nature of this backups makes them pretty useless in this system state - because they are just images of partitions.
Only software that can write directly to those partition may be able to utilize those backups, there are a lot of post on this forum describing TWRP routine for making update packages based on LGUP backups.
So unfortunately there is only LGUP, but it only can make backups but can not restore them as it uses some special file format (KDZ) that containing some dll's and data files (like glued partition images with special info of where to put what) and i didn't find a way to make my own KDZ files from backup images.
I'm now getting another idea - that this can be a blowed fuse in CPU ARB protection mechanism, if anyone has experienced ARB 1 please confirm that system should be in this state in case of ARB error
I have an H872 on Havoc 4.4. I have upgraded to a Pixel and will be giving the H872 to my father-in-law. He will only be using it for phone calls - very unlikely he will text, and definitely won't use data. It will also be his first smart phone. Since the H872 is rooted, when it boots up it gives the warning display that the phone may be "Corrupted". I don't want to have to explain all that "root" stuff to him, etc... I want the phone as basic and simple as can be, hence , I want to reflash the stock firmware.
I am having troubles though. Booting the phone into download mode and starting LGUP fails to recognize the phone. I've tried with Uppercut as well and it says I'm missing a file in Apps/Roaming, etc...
Not sure the problem because I have reflashed stock many times with LGUP. Could it be that Havoc has changed the "identity" of the phone, or that it's on Android 11?
Any help to get this back to stock is much appreciated!
Got it figured out. Flashed back to an older TWRP (was on Orange Fox), flashed an old stock Oreo ROM, and then was able to flash kdz with LGUP.
