Possible problems

3. Does not load completely or Bootlap - turn off the smartphone, hold down the Volume down and Menu buttons, in the Recovery menu select wipe data/factory reset.

If your smartphone does not want to boot normally, works poorly or does not work at all, you should try flashing it. Fortunately, almost all LG Android devices are flashed the same way. You can do this either using the KDZ utility or through the official LG Mobile Support Tool. We will now describe the sequence of actions.

This instruction applies only to GSM devices. The CDMA firmware has not been tested against it. The method has some dangers. If a failure occurs during KDZ operation at the time of bootloader recording, only a service center can restore the device. We recommend choosing a good cable in advance, charging the battery in the laptop, disabling antivirus software and turning off other programs. It is better to use the cable that came with the device and place it in the rear socket of the computer. There may be a lack of power through the hub.

Warning

The administration is not responsible for the actions you perform with the device. This material is provided for recommendation purposes and not as a guide to action.

Preparation

To get ready for work, you need to download several files

The official firmware itself in .KDZ format

Install all the drivers one by one and just in case, LG Mobile Support Tool. You will need it if the drivers are not installed (read in the last part of the article), for the usual update of the official firmware and restoration of the brick. Unzip the KDZ folder to the root of the system disk. Place the firmware next to it.

In KDZ you need to find and install the msxml.msi package using the standard method.

Now we put the phone into firmware mode. To do this, completely turn off the device or disconnect the battery. If it is not removable, press and hold the power button until the screen goes dark and the device vibrates twice.

Hold down BOTH volume buttons and power button. After a few seconds, a yellow image with a caption will appear. Emergency Mode.

Now we connect the device to the PC and check if the drivers are installed.

If everything is fine, let's move on to the firmware. No - we restart the computer, try another port, cable. Without drivers, the firmware will not start! You can also try downloading them using the LG Mobile Support Tool. Read about it below.

Firmware

The drivers are installed. The phone is visible. It's time to launch KDZ. Go to the folder with the installed flasher and open KDZ_FW_UPD.exe as an administrator. If it doesn't work, right-click on the file and set it to compatibility with Windows XP SP3. Flashing on Windows 8, 10 is not recommended. For your own safety, find a computer with Windows 7.

The KDZ start screen looks like this. Set the values circled correctly.

Now you need to select the firmware itself using this button.

Click Launch Software Update and wait. The utility may hang; the process sometimes lasts more than half an hour. It's better not to touch anything. Then progress bars will run across the screen, and you will see the treasured message about the end of the firmware FINISHED. KDZ sometimes behaves erratically. In our case, she flew out immediately after the procedure was completed. Because of this, the image is different.

The phone will reboot itself and begin charging. Disconnect it from the cable, disconnect the battery and turn it on by holding the “power” button. If the device does not work, try entering Emergency Mode again and flashing it 2-3 more times. Sometimes the LG Mobile Support Tool utility also helps restore operation.

Updating the official software and restoring the “brick”

Nobody forbids you to try the official software update utility. It happens that it helps to cope with particularly obstinate devices. Open LG Mobile Support Tool

Click “install USB driver”, mark your model and wait until everything is downloaded and installed.

Connect the device. If it is in working order, but there are no official firmware updates, the program will write about it.

When the “start updating” column is active, try selecting it and following the program instructions. Everything is simple and clear there. There is only one drawback - the LG Mobile Support Tool takes a very long time to download the firmware. Don't expect a quick solution to the problem.

We hope everything worked out for you. Good luck with the firmware!

How to flash LG?

LG produces many popular smartphones running on the Android operating system. It offers the user a wide range of devices, among which everyone can choose an excellent option, both technologically and financially. But it’s worth considering that smart phones are much more likely to suffer from various “glitches” and software errors compared to simpler models.

In order to restore the functionality of a smartphone that has begun to work incorrectly or slow down, a flashing is necessary. This procedure allows you to download and install a working version of the software on your smartphone. In addition, this operation is necessary before going to the service center if, while using the device, you made any modifications to the system files or gained root access.

It is worth noting that there are a lot of unofficial firmware for LG smartphones. They can significantly expand the functionality of the device, as well as increase its performance. But their use can also lead to unpredictable behavior of the smartphone: sudden application crashes, reboots, overheating, etc.
