Hey guys so im new to the lg v line. Been a previous nexus junkie but made the switch to the v20 Ive had my tmobile lg v20 h918 for about a year now and had no real reason to root or reflash the stock file. But as of recent had issues with lagging and a "lucky wheel popup" malware i believe) . So trying to flash back to the original file and completely wipe my device and start fresh. Im currently on h91810s android 7.0 but cant find a kdz to wipe and reinstall or a working lg up tools software version. I would like to root but from the research ive seen on 10s theres no way to revert back to a older version to root. I was able to unlock my bootloader but aside from that having trouble find any of the other stuff. Any clue??

Hello
I'm having troubles with my new LG Optmus L5 e610. It comes oot with 4.1.2 and the LG mod v20b.
I rooted it with the v20d_root.kdz and now i've installed an unlocked bootloader, CWR, CM10 and Gapps. I have now a problem: the IMEI inside the information menù is empty and every SIM card is not recognized.
What should I do? I tryed going back to the stock the reflashig all, but nothing. By the way the stock ROM works fine.
Investigating around i discovered the same problem over many Samsung devices, with following solutions talking about this EFS folder that needs to be backed up. Googling around i found that LG don't need to back up this folder. Am i wrong?
EDIT:
Googling around i discovered that flashing a rom fro the v20_root may cause this issue, so it is advised to downgrade to the v10. But how i do it without making the kdz flasher give me errors? And which one of the v10 kdz i have to flash?
Hello,
You must install v10 baseband.I'n on mobile now and u can't help you but serch on google for it.
Sent from my P700 with GSIV rom and some tweaks in it
Hello guys, I have a D802 phone and I was on Ressurection Remix 5.0 but since the official lollipop update was made avalaible, I wanted to return to stock and unroot so I could again use my warranty(for some weird reason they couldn't tell last time I took it there that it was rooted). Basically my problem is that every guide for going back to stock has the phone connected to the PC and use the flash tool. Well, I did that but when the mobile support tool opened for the upgrade, it couldn't find my phone. So I found a guide that showed you how to extract and rebuild a kdz file into a .zip. I tried that, used the UK d8023b rom ( A friend of mine who has a d802 as well, though unrooted, got the prompt to update through the pc suite and it updated his phone to d8023b, thats why i used that version), flashed it and I am now stuck in a bootloop. I have full access of recovery and adb but the phone isn't recognised by LG software. Can you please help me use my phone again? Going into download mode didn't work with the flash tool.
[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.

Hi
I had unlocked my lg g6 bootloader, and installed custom rom.
After few months with custom rom, I want to get back to the stock lg rom, with dual camera and L1 widevine.
So I tried to install the stock rom and relock bootloader:
Using LG up , downloaded .kdz file, and upercut, I get each time dll problem. The LG up version does not match with the phone version. I tried to place or replace some dll files found online in LGUP/common/LGUP_Common.dll
Nothing happens, I still have this issue.
Then, I tried with LG bridge (update - repair update).
It worked, I installed the stock rom. I still had the bootloader unlocked.
I locked the bootloader with adb and fastboot, and did factory reset.
So why I am posting this message ?
Because now, with the stock rom installed by LG bridge, I have L3 widevine and not L1. And the camera application (and all apps using the camera) does not work.
I think, I need to rewrite properly the original rom with LG up, but I don't know how to make it work properly. I used one time LG up by the past when I soft bricked my phone, and I did not get any dll issues.
Now, I am trying to do it, and nothing works. I tried 2 computers (1 windows, 1 linux+Windows VM) nothing.
kdz problem, dll problem, computer problem ? I don't know...
I really wish someone could help me
Thanks, very much.
If you are coming from Custom ROM to Stock, you need to flash Nougat first. If you dont your camera wont work.
I think that like my old LG L9 the G6 has a PROM/fuse bit which remembers if the bootloader had been unlocked once. This could explain the Widevine issue. Samsung introduced Knox years ago, which also won't ever forget unlocking and prevent further use of certain Samsung applications.

Did you solve?
Cause I did almost same things as you: wanted to go back to stock after experiencing some random reboots with lots of custom roms (which worked till few months ago) and so flashed back the original Pie (H87030b_00_OPEN_EU_OP_1105.kdz) via LGUP but ended up with camera and flash not working at all.
While on custom rom everything works smooth, a part from random reboots
Right now I'm flashing H87011i_00_OPEN_EU_OP_0108.kdz (Nougat) but I'm not sure if it will solve the problem.
Thanks in advance
EDIT: camera is working on Nougat, butnow I have to deal with that damn "moisture" notification
EDIT2: after almost a full day of updates I can use my LG G6 with stock rom, stock camera and be very happy with it ;-) thanks @SkylineDiT for the tip of going back to Nougat, didn't know it.
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.
