Hello boys and girls! As many LG Optimus L7 owners have this problem, and some others of you may have this too. I’m writing this tutorial to unbrick / return your phone back to the stock rom.

Warning: I won’t be responsible for any damage to your device, this has been tested and working on my device, good luck!


How to Unbrick / Return LG Optimus L7 Back to Stock Steps:

  1. Download and install USB Drivers on your PC
  2. Download the official stock firmware
  3. Download KDZ_FW_UPDATE.zip and extract it,then open the folder where you extracted it and Start KDZ_FW_UPDATE_EN with Administrator Rights (Right Click on file and select Run As Administrator)
  4. Once the program started, in Type select 3GQCT and in Phone Mode select EMERGENCY, then in KDZ File select the downloaded firmware and press open.
  5. Make Sure your Phone is connected to the computer in EMERGENCY MODE( Remove the battery from the phone,then while pressing Vol+ Connect the usb to the computer,a yellow screen must come up showing EMERGENCY)
  6. Once you’ve done this,press Launch Software Update and let it work,the procedure takes about 5-10 Minutes,so don’t worry.
  7. At the end of the procedure the phone will reboot and an LG Animated Logo will come up,and after some minutes KDZ_FW_UPDATE Will say you that there has been an error, don’t panic.
  8. Congratulations.

Caution: Don’t unplug the USB cable until the setup has finished.

Thank you. I’m so happy right now.

The error message on Step 7 is “MOD UPTestEX MFC Application has stopped working”.

Step 8 should be to insert your battery back in your phone.
