Installing official firmware on LG G2. Official LG firmware via KDZ Official software update and brick restoration
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 with KDZ utilities, or through the official LG Mobile Support Tool program. 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 the operation of KDZ at the time of recording the bootloader, only service center. 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 a regular update official firmware and brick restoration. Unzip the KDZ folder to the root 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
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, click on the file right click and set compatibility to 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 and official updates there is no firmware, 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!
