KDZ ERROR "File Extract Error." "Finished"

hey, i have an LG optimus G 97310H i have rooted my phone but now i must send it away as it is having hardware issues.
i used superSU to permanent unroot. but for some reason SUPERSU PRO is still in my applications list.
and it dose not give me an option to remove just Enable OR DISABLE. so what im trying to do is remove it. so i thought if used KDZ and installed the official ROM. i downloaded the ROM from 2 sources. and when ever i put my phone in download mode. KDZ gives me this error.
"File Extract Error."
"Finished"
any help on how to fix the KDZ error. or if i can remove the superSU another way?
**** its also not a custom ROM installed ***

Corrupted kdz? low free space available? virus?

Reboot pc and try different usb port.
LG Optimus G E971

I see no any reference between "File Extract Error" and "different usb port"
.KDZ is an archive, which will be privately unpacked by update tool and if the checksum of .dz (or .tot) is ok, flashed to the device.
"File Extract Error" means .kdz unpacking went wrong.

hmm mayve it is a bad kdz. do you know where i can find another one?
i tried one from the LG tool i found on here and one mirror

Any updates for this issue? I got a LG Optimus G Pro F240L from south korea and it is stuck in download mode. Everytime I use KDZ updater I got the same error: Extract File Error
Since it's a model less common I managed to get the KDZ from only one place (lg servers).
Need help lol!

KDZ unpack error
Have the same problem. Mine is Optimus G E977. I download 4, Official KDZ stock from LG Firmware list and very one gives the same error. I try to donwload again, and still the same error.
I also have a Optimus L7 and KDZ update function flawless. Maybe it's because the size (more than 1 gb).
Would appreciate any help

I think it's a corrupt download.try to download the kdz from browser,not with kdz updater.

KDZ unpack error
I already did. I download several KDZ files from different sites an for different countries. Nothing works when size is more than 1.0 gb. Smaller size files works well. The problem is that almost all KDZ files for Optimus G are more than 1.0 GB in size.

KDZ Unpack error
Could unpack several files (all of them less than 1.0 gb).
But large KDZ files (more than 1.0 gb) couldn't
Anyone knows where to get the latest version of KDZ_FW_UPD

You can't use lg mobile tool when you are on custom rom. The phone will be detected,but when you will choose to flash stock it will give you an error.
The only way is kdz updater.

If that .kdz file is bigger than 1gb, kdz updater will not work. Simply as that.
After searching around,i found there is a way to bypass official LG mobile support tool checks.
It's a litle more complicated,as you need to install small server and you have to edit hosts file in windows, but it will do the trick. You need to do this in order to make the app thinking it's downloading the rom from lg server.
here is the tutorial

It's for the L9,but i think it will work F180 too....

it's not working. Even if it's file downloaded earlier with LG Mobile Support tool - it crashes during file extraction. Tried this with previous version of LG MST (this from thread You mentioned). Don't know why - tried only with one *.kdz.
BartxGamer - You can try this, but LG Mobile Support tool will update to new version, and it's hard to say - will it work?

You're wrong. I always go back to stock rom with this. If Phone is recognized with newest firmware, then You have to choose from options "Emergency firmware" and find ROM using IMEI.

there is an "IF" there.You got lucky, not working for everyone .What do you do if the phone is not recognized?

OR we will wait till official android 4.3 for F180k will be released. Than we should be able to update, i guess.
Yep, IF phone is recognized. But what if not? I tried it twice. And it stopped after checkint battery stats. You could only restart update or exit. And it writes, phone is nit connected.

[Q] Software Update for Rooted LG G3

I have the D855 international, with v10f. It's rooted with PurpleDrake Lite. The phone has just downloaded a software update, which I have NOT installed. Can I install it? If I do install it:
- will I need to root again?
- will anything else be affected?

If you run the software update it will either work (and root will be maintained) or it will fail with a message that your phone is suspected of being rooted and boot back up unchanged. If it fails then you need to unroot first by flashing a KDZ of the version you are using in Normal Flash mode to retain your data/apps

You can try this method first to lose root and update your device:
http://forum.xda-developers.com/showthread.php?t=2797190
If not, you can also follow this guide to flash your current .kdz file again and lose root like that.
http://forum.xda-developers.com/showthread.php?t=2802286
If you want to find your current .kdz file, you can use this link:
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI HERE
You have to put in your IMEI after the "=". That will take you to a page with some info. Use the link next to "<sw_url>", copy it and that will start the download of your latest rom (in form of a .kdz file).
(Not sure if I pasted the links in the correct order, but the first one should be regarding the use of LG PC Suite and the second one about flashing .kdz files)

I can confirm this KDZ works fine. I can also confirm that flashing this KDZ using the LGUP tool works perfect. I actually kind of like it better than the other flash tool. I like how it throws it into download mode automatically.

LG UP is better because it is an official tool made be LGE, and also it puts the phone automatically into download mode (and also it is newer than LG Flash Tool )

Unfortunately, it seems that the LG KDZ link isn't working any longer. Does anyone have a mirror for the file, please?
