Here is the current KDZ files for flashing / unbricking Your LG L90 Back to Stock! It will be the same method as the G3, G2 and G Pro, G Flex, Etc.

DISCLAIMER: This procedure is NOT for the faint hearted! If something goes wrong and you fry your device, I cannot be held responsible.

All things you need to download:

  1. USB Driver for your windows
  2. LG Flash Tool 2014
  3. LG L90 Stock Firmware
  4. Visual C++ Runtime Library (If you cannot run LGFlashTool2014.exe): Download

How to Flash / Unbrick LG L90 back to stock:

  1. Download all requirements, install LG USB Drivers, extract the LG flash tool zip file. And to make things a little easier, put the firmware in the same directory as where you extracted the flash tool files.
  2. Make sure your phone into download mode. Shut your device down > press volume up and plug the usb cable immediately.
  3. Then open the LGFlashTool2014.exe up. For ‘Select Type’ choose 3GQCT. For ‘PhoneMode’ select EMERGENCY. Then go down to Select KDZ file. In the "Select KDZ file" enter the firmware of your LG L90
  4. Now Click normal flash. A window should pop up, Click Start
  5. Now "Select country and language" small box will open. Here select "Different Country" and "English" and press "OK"
  6. After a few seconds a screen will appear saying "The phone is disconnected from PC.". Do not click on any button.
  7. Now again connect phone in Software Upgrade Mode: Switch OFF the phone and Press Volume UP button and insert USB cable into the phone, Now phone should show Firmware Upgrade Mode and click retry button.
  8. After the process completely done, your LG L90 will start rebooting.

Bootloops fix:

You can fix this by shutting down the phone, starting the phone with the power and volume down button pressed, releasing those buttons when the LG logo shows up and immediately pressing them again, then choose to perform a factory reset. After factory reset the phone booted like I expected it to.

Will this method work for LG G2 D802 32GB??

I followed the instructions but even after disconnecting and reconnecting phone does not enter firmware mode and stays in download mode.

What should I do??

hey man, for the lg g2 (in my experienci d805) y was have some problems like you Kunal

1. check the usb cord, extremely recommended to replace with one original for a brand (LG, Samsung or Motorola), try to not consider the other brands.

2. Check the usb port, try to change to another,
3. check the USB drivers according to the phone and OS Version.
4. try to run the program in administrative mode (windows), this may help you in many cases.

good luck 🙂

It wil not connect.
