[Q] Unable to upgrade software to v20H

I have LG G3 32gb D855, my current Android version is 4.4.2 and when I check for updates via the LG PC Suite it says I can upgrade my software to 20H.
I proceed with the upgrade but when it says "Analyzing Upgrade Environment" it skips to the end and gives me an error:

Everything is connected, I've installed the drivers (Windows 8.1).. What can I do?

Anyone please?

Exactly the same problem here I'm afraid and no clue how to fix.
I've got the 32GB model and currently running 5.0.....
Any help greatly appreciated.
EDIT - sometime I get this message instead - I've only used 6GB internal memory and none of my SD card.....

Hi , go here : http://lg-firmware-rom.com/ and enter your imei number and download the latest firmware for your phone.
then, follow this tutorial :http://forum.xda-developers.com/showthread.php?t=2785089 how to flash a KDZ using LGFlashTool2014. Good luck!!!

Thanks twisted_twice, I'll give it a go and report back!
EDIT - after several crashes of the update tool - it worked! I seem to have gone from the European software version (V20a-EUR-XX) to the Taiwan version (V20h-TWN-XX) but I don't suppose that's an issue.
Now, if only I could get the handset to show 4G (only get GSM/WCDMA auto) options.....

LG G4 Problem with driver

Hello guys!
I am trying to update my LG G4 to Android Marshmallow but no success.
I am doing everything as is wrote in guide, I tried to search internet for help and nothing works
When I reboot into download mode, pc does not install drivers.
I have latest LG Drivers, LG Flash Tool 2014, KDZ file, Windows 7 64-bit
I am using original USB cable, different cable, different ports, latest drivers (tried also older ones)
I tried to restart PC couple of times as well as my phone
I have got this error:

}
This is how Device Manager shows my device in download mode:
Tried also manual installation of drivers:

i have exactly the same problem..... but i think that something happend when i trait to use the LG Flash tool..... before i try to update... my drivers have been working fine

@nothingfacey yes me too and its normal he recognize on bridge for example .and when you try to flash for roolback you cant . first bcz there are anti rollback on the motherboard and second because for the moment the flashtool need to be update because the dll on the kdz is not the same

I am having the exact same problem and I have yet to find a fix.
I noticed that I could get ADB to temporarily work after switching to/from MTP/PTP mode multiple times randomly with unplugging/replugging. It would be interesting to see if anyone has found anything reliable.

Have you tried LGUP? That does everything automatically.

HTC Sync manager upgrade phone message

I get this message, with the same version number, every time I open HTC sync manager (all 4 times, I just installed it for the first time a couple of hours ago)
The first time, I ran the update and it definitely flashed something to my phone. (was in recovery mode flashing for a few minutes).
After it booted back up, the phone behaved sluggish as typical with a software update, but when I went to settings, there were no version changes of Android or of the firmware version. So far I can't find anything different, but there was a lengthy download and flashing process.
Also, I checked for updates via the phone settings yesterday and also today as soon as I saw the upgrade notification, and it reported no updates available.
(unfortunately, I didn't think to check appdata\local\temp until it was done, and there was nothing in there that would have been the size to match the lengthy download time at 5MB/s)
Anyone else seen this or have any thoughts?
My initial thinking is that the HTC Sync manager software is a p.o.s., but it's the only way I've been able to transfer files to/from the phone on either Windows 10 or Linux Mint 17. (Thanks HTC )

I have this same update. I tried once and got stuck on a HTC flash screen. Havent tried since as im trying to root the device. not download anymore of verizons security scams.

It's never worked for me. The problem might be due to their DNS not working, so the update can't be requested. One other way would be to connect your phone to a power source and boot into recovery mode, there's an option for "download latest and recovery", which should install 9.0.1.169 on your device. Although this feature won't erase your device, it's wise to make a backup beforehand anyway.

Having the same problem here. Wrote an Email to the LG Support with my IMEI. Turned out that i got a Demodevice that can´t be updated.

Your phone has a cross Firmware. For sure a Sprint version (G710PM) with a 710ULM firmware flashed. LG bridge DO NOT GOING TO check your phone.
If you want to update to latest pie firmware you can do what I (and others) did, to flash manually the firmware by youself. I did it twice, my wife's phone and my own phone. 5 minute and you gonna have Pie 9.0 with 1 Oct. 2019 security patch.
Link with instructions <<Here>>
Good luck!

Have same issue, there is no cross firmware that I am aware of blocking me here...

its 2021. I bought 2 unlocked lg 8 thinq from amazon for me and my wife from a different seller. hers was one that came with alexa. Hers is through verizon/total wireless, mine is from att or tmobile with metropcs service. Hers updates perfectly and gets all the updates while my phone is stuck on the very first system update without a way to update. I'm on G820UM10i I tried lg bridge. It finds my phone but gives me a error and wont check phone for update. Will this work for my phone and how could i do this if i have a newer version needing android 10?
