Alright, now i'm going to show you how to flash LG G pro lite using LG flash tool, this method does not required internet connection (offline).
So basically you need to download the kdz firmware for LG G pro lite and LG flash tool, this way you can flash your phone offline.
You maybe asking, why do i need to flash my phone? well here's some reasons why you want to flash your LG G pro lite:
your phone stuck in bootloop
you want to completely unroot the phone
you want to upgrade from jelly bean to kitkat
you want to downgrade from kitkat to jelly bean
your phone runs very slow and you want fresh install
you want to sell your phone
Remember that this is a DWYOR tutorial, means do with your own risk, this flashing method is tested successfully by me, but i'm not responsible if you damaged your phone.
Here's all the ingredients for this tutorial (stuff that you need)
LG united mobile driver,
LG G pro lite kdz firmware
LG flash tool 2014,
Visual C++ runtime
Computer running windows ( i use windows 7)
The LG G pro lite itself
Micro USB cable
Donuts and coffee with less sugar
Courage and confidence
Okay, after you get all the ingredients, we can begin to flash the phone, and don't forget to backup your data first, because all data inside internal memory will be gone after flashing.
Step by step how to flash LG G pro lite
install LG united mobile driver
install Visual C++ runtime
run LGFlashTool2014.exe
select type "CDMA" and phone mode as "DIAG"
select the kdz file (the firmware that you're going to use to flash the phone)
put the phone into download mode, read my previous article if you don't understand
click on "Normal Flash"
click ok on "select country & language" window
wait until the whole process finish
It's actually very easy to flash LG G pro lite offline using LG flash tool, now you can go from jelly bean to kitkat back and forth.
This flashing method could also be applied to other LG smartphones that runs android, such as LG G3, G2, G2 mini, etc.
NOTE
when i was flashing my G pro lite dual from kitkat 4.4.2 to jelly bean 4.1.2, after finish flashing i got stuck on boot logo, i solve this by doing factory hard reset and the phone boot normally.
make sure when you plug the phone to computer (download mode) there is no error message, install the latest LG united mobile driver.
it is recommended that you do factory reset before flashing your phone.

I will try to make my question as simple as i can.
I bought a used LG Optimus G F-180 yesterday. Its rooted with a custom ROM installed (i checked through many apps from play store, they all showed that it has root access). So my question is "How do i unroot it and revert back to the original software/firmware/ROM? And after reverting how do i update it to stock 4.4.2 KitKat?"
Please provide step by step instructions and links as im new to this rooting/unrooting.
Cheers!

There are a lot of threads about flashing new ROM. Dont make in future more similar threads.
USE SEARCH BEFORE POSTING.
Hi,
IM NOT RESPONSIBLE FOR ANY DAMAGE OR UNSUCCESFULL FLASH. EVERY PHONE IS DIFFERENT. EVEN EVERY LG OPTIMUS G IS DIFFERENT, in its way.. YOU BRICK=YOU FIX.
YOU CAN FOLLOW THIS GUIDE TOO. http://forum.xda-developers.com/showthread.php?t=2498102
But LG flash tool 2014 is simplier.
First make sure you have:
Fully charged phone,
Know how to enter download mode (turn off phone > hold volume buttons > connect to pc)
Turned off debugging mode
IF SOMETHING GO WRONG AND YOU WANT GO BACK FROM DOWNLOAD MODE, HOLD POWER BUTTON FOR ABOUT 10 Seconds, than release it and phone will restart. But disconnect from pc first...
DOWNLOADED:
LG flash tool - http://forum.xda-developers.com/showthread.php?t=2797190
Drivers.
KDZ FOR YOUR LG VARIANT.
Download LATEST LG Mobile Support Tool
All your data will be removed.
0. Unpack zip with flash tool somewhere to NEW folder. Name it what you like.
1. Enter download mode
2. In the LG Flash tool choose 3GQCT or CDMA it depends on what u have.. I guess 3GQCT
And choose CS_EMERGENCY (always when coming back from custom ROM)
And choose KDZ with your Original system, which HAS TO be placed in LG FLASH TOOL folder.
3. Click Normal Flash > Start > choose region (korea) and language (what u want)
4. Now the process will begin.
5. After finish flash, your phone can bootloop. Than you have to make reset to clean it up.
6. Done, you have clean system and everything.
Tip for future.
!!Dont change radio in LG, you can mess it up...!!

Phone is LG G Pro F240L. I had the latest update (Lollipop) installed and let's just say I wasn't satisfied with it.
I flashed Kitkat KDZ like normally but it got stuck on bootloop, then I CSE flashed using the Kitkat KDZ and now it won't do anything other than go to download mode.
I would really appreciate any help to get my phone back to normal and fast. Thanks!
EDIT: I should also add that I've tried the PC suite recovery method but it says my phone's battery is too low when it's not.
UPDATE: I think I've hard bricked my phone. Damn...

Reflash the kdz again.before that check whether you are flashing the correct firmware of the correct model.
Now flash your kdz through lg offline flash tool.you can get that by searching in this xda forums.so even if your battery is below 60% it continues to the next step.But it is recommended to have minimum 60% of battery level.after opening lg offline flash tool you choose the kdz,then after choose cse flash.thats it.because it worked for me.or if your phone goes intlo reccovery mode,simply you can factory reset the data,perform 3 wipes(factory reset,cache and dalvik cache) and reboot.It may work sometimes.update me after u did these steps.if worked hit thanks. (i want to help you.thats why,i said what i know.)

I'm a newbie and don't know much about phones. I rooted my phone for the very first time and was about to install CWM.
I've an LG Optimus G Pro F 240K.
I downloaded an app namely Flash Optimus G in .apk form and installed it on my phone. I tapped on Flash and the screen read "SUCCESS! Now re-boot you phone into recovery." I tapped Reboot into recovery. That time and now, i'm numbed. The phone isn't responding at all. I'm using Windows 10 Pro. In device manager, an exclaimed mark icon gets visible when i connect my phone.
The device name is QHSUSB_DLOAD.
I've downloaded official stock firmware 4.4.2 kitkat. When i use LG Flash Tool, it says your device isn't connected to your computer.
What should i do???

Or downgrade to Windows 8.1 and then restore by KDZ
qhsusb_dload means you´re in qualcomm mode, and also means that you´ve killed phone boot. from what I know, only medusa and riff boxes can fix it.

Hello,
I have a lg g pad 8.3. Today I've tried to do the downgrade Lollipop -> Kitkat, but something wrong and I have the boot logo restart. But I've put my G PAD in download mode and now I'm trying to install various version of stock version through LG Flash Tool. But on my Windows 10, I receive the error "LGUserCSTool LG Mobile has stopped working........", while on my Windows XP pc, the .kdz of the version 30a.kdz stop the installation at the 95% and the LGMobile Support Tool tell me to retry the installation, while with the version 10b.kdz, finish at the 45%.
What I have to do now?
I see only DOWNLOAD MODE on my tablet, If I shutdown the tablet, reappears the Download Mode, no LG Logo.
Sorry for my bad english.
I followed this guide but used the 10b.kdz instead of 30a
http://forum.xda-developers.com/lg-g-pad-83/general/tutorial-korea-v30a-how-to-flash-t3076576
I noted that using 3GQCT worked fine (but required a hard reset)
CDMA caused "LGUserCSTool LG Mobile has stopped working"
Like a lot of people I have the eu version of the h815 and managed to bootloop it after following the garbage methods online for rooting .. I came here for help and found all the methods listed... lg up, lg flashtool 2014 etc.. the problem was that my phone just wasn't recognized by the computer, it charged well but that was it, lg bridge, lg up, lg flashtool.. none could find my phone.. I thought I was doomed to a soft bricked paperweight and even began contemplating the hundreds of pounds needed to purchase a new phone.. however after hours and hours of tinkering I cracked it and now have a working lg g4 again.
first off download and install lg up dll file
then install lg up but don't open yet
find and make sure u download the correct kdz firmware file ( I needed the h81520d file which I downloaded from storage cow as devtesters didn't work for me)
now head to your computer control panel and delete(uninstall) any lg mobile drivers that you see.
connect your phone through usb into download mode and leave connected
once that's done download the old drivers (4.0.4 I believe) and not the newest 4.1.1 or whatever it is now.
then open lg up and hopefully like me you see your recognized phone.
click upgrade (not refurbish) and click bin.. right of bin is the ... symbol.
hit that, choose your kdz file and voila.. let it work its magic..
DAMN IM HAPPY. HOPE THIS CAN HELP SOME OF YOU LIKE IT DID ME.
