HI , first post , so here goes....have an old optimus g which i tried putting recovery on it....when phone rebooted , it had the secure booting error on it ....i went to the xda unbricking guide and have been stopped by the fact that the lg mobile support tool does not see my phone , and after i have downloaded and installed the drivers for my phone the lg optimus e973 .....
Verify that your phone is recognized and connected by checking the LG Mobile Support Tool. The text "Waiting for connection...." should be replaced by your model version LGE975 LGE970 or similar
..........i think i put the right drivers because i looked for them under the driver options for my phone ...but it still will not recognize my phone ...thanks for the help ...if any....have a great day.:cyclops:

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'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.
