You can downgrade to Nougat operation system with LG UP. Click on the link below for information about LG UP.
https://www.lgdestek.net/lg-up-ile-stock-rom-yukleme-21133/

stay away from h850 kdz for now, h850tr has source codes released. will be rolling out in a month or so

You need to identify the Qfuse (anti-rollback) version of your phone and the kdz firmware you want to flash.
if the nougat firmware has a lower Anti-rollback version, You will hard brick your phone when you try to downgrade it to nougat

You didn't say which G5 you've got, but all KDZ files for the H850 can be found here: https://lg-firmwares.com/lg-h850-firmwares/
If it's not the H850, click on the "LG G5" link in the LG Series column on the right hand side of the H850 page for more models.

If you've rooted your phone, that's probably why the OTA update failed. To get the OTA update you'll first have to flash one of the stock KDZ files posted for your phone, accept and install the OTA update to get the latest firmware, after which you can TWRP your phone with fastboot and flash SU.

my phone isn't and wasn't rooted.. so idk where the problem is.. i tried the IMEI kdz finder and they don't work as well so i can't find the kdz for my phone... D: maybe it's because i flashed a kdz with flashtool before (my phone is vodafone branded and i didn't know that i baught it from amazon from the original LG... and i got an branded device so i installed an open EU kdz..
@N0!Z3 ExPl0
this could be the reason because you didn’t find 20b on LG firmware sides. 20b seems to be a "vodafone only" update!
as i know, this problem appears because your phone is a vodafone brandet phone!
You have to debrand your phone if you want to use other firmware for it. Ask Google!

LG V30+ Korean Version in Dubai, no receiving the Update of Android Oreo 8
Hi,
I am using The Korean Version of LG V30+ in Dubai. I still couldn't find the update of Oreo 8 here. Kindly advise how to get it.
Thanks

Hi,
If I get oreo firmware of korean v30 v300k and I flash it in my european v30 h930, what would happen? It will works?
No it won't work. You might even brick your phone... if you manage to find a way to flash a firmware not intended for your variant.
You can't install install incompatible rom on this device. Installation process should check the model number to match your phone. That means it will show just an error, but modifying the rom file might allow you to install it. But it won't boot because the korean version has different modem.
Does anyone know if it is possible to install h930 rom on h930ds? I have heard that the modem inside is different, but I am not able to find official information.

Not only to have Oreo, but for bootloader unlock and root and to have freedom.
Ability to run custom ROMs like Boombox.
You can use CIS H930DS OREO KDZ or H930 Oreo KDZ. In both those threads, I have LGUP attached, which you can use to easily upgrade to Oreo. OR you can go one step further, and bootloader unlock and root before LG releases the update that will BLOCK that.
Lots of India users have done that.
See post #193 of the WTF thread.. Full instructions are there for bootloader unlock and root.

LG V10 H901 Unbrick Help Required

Hey could you please help me figure out something. I have an LG V10 H901 (purchased from China) its supposedly the T-Mobile version but was manufactured in Korea. Its WIFI and bluetooth weren't working so I tried to update its firmware using LGUP. However, after the update it was hardbricked. I have managed to get to the LG logo using H90021w Unbrick Qfil files. Afterwards I tried to flash stock firmware H90130d_00_0611 using lgup. However, I got a message about partition changes and hardbrick once again. I have also tried KDZ files related to F600L, h90021w and many others. Can you please suggest based on my details:
-Correct QFIL files
-Correct Firmware or KDZ
Phone Details:
IMEI:354017070602111
Model:LGH901BK
Suffix:ATMOOP
Buyer:TMO
Software Verison:H90130D_00
OS Version:N
File Name:H90130d_00_0611.kdz
KDZ File size:1975399272
I had a similar problem, in the case I wanted to update do Nougat. After that I unbrick the phone. Try to install the H900 AT&T 6.0 MM firmware and it will became a H900 and go back to life. My H901 became a H900 AT&T. If only install the firmware doesn't work, then will need the Octopus to install.

Try to flash the AT&T version firmware after You unbrick your Phone. If doesn't work, you'll have to use the Octopus Box to install the ROM in your V10.

LG V30 Demo unit bricked then fixed with a wrong bootloader version now no wifi

Hello
I have Lg v30 model H933 and this guy who repaired my phone after it got bricked, flashed boot loader version of US998, now my question is if a flash firmware US99810c_03_1216.kdz will it brick my phone? It did brick my phone when I flashed US99810d_01_0411.kdz which is an Android oreo firmware.
SO my phone is booting up and working right now with firmware H93320h_00_OPEN_CA_OP_1123.kdz which is an oreo android version, this phone came with a nougat version and wifi was working on nougat so now i am trying and testing all the different available nougat firmwares available for V30 phones and even for different models just to see if any one of them would work so far none of the nougat firmwares have ever made further than lg logo screen at the startup of boot, and this is with any nougat version firmware i try regardless of their models of course still all for LG v30 .
Flashing Android oreo firmwares always started and booted nicely with any suitable model so far that I have tried but no wifi still and nougat no matter whichever model LG v30's firmware i try never made it past lg logo screen.
Please let me know any possible solution or idea anyone may have.
Thanks

For all V30...
10d is still Nougat.
Oreo starts with 20a, and goes up higher.
First Pie will be 30a.

Sorry my bad You are right, I flashed US99820d_01_0710.kdz and it got bricked and thats when I had the guy flash the boot loader again to get it to download mode again and then I flashed H93320h_00_OPEN_CA_OP_1123 the oreo version and phone is booting fine but no wifi so i am trying to get the nougat version flashed in this phone and get it to boot properly to see if wifi will work on nougat or not.

The wild card is whatever the guy did to unbrick your phone. You may no longer have a "normal" phone. You SHOULD be able to flash US998 Nougat, master reset, then flash any version of US998 Oreo. With H933 you would have to DL Partition to US998 both times or even use Refurbish. It's in the Frankenstein instructions and countless people have done it. But the repair guy may have done something to interfere with that happening.
