Installing official firmware on LG G2. Installing official firmware on LG G3

There are a sufficient number of ways to flash mobile devices. However, it is important to remember that for each device it is necessary to choose its own flashing method, despite the similarity of the basic principle.

Let's take a closer look at the method of flashing official ROMs. This method helps not only to update your device, but also to change the region.

This method cannot roll back firmware from V20 to V10. This is provided for in other instructions. If in the future there is a need to return the native firmware, you will need to:

1) go to the service menu by dialing 3845#*880#;

2) find the “Version Info” item, in which select the bottom line “Factory Version”. Here you can find a detailed description of the firmware indicating the region. All information from here must be rewritten and remembered, because returning the firmware for the native region is of great importance for IMEI compatibility with the firmware region.

Where to find and how to download.

Official firmware versions in .kdz format for all countries are available. In this case, we need CIS firmware intended for the CIS countries.

Firmware of the device.

It is important to remember that you will perform all further actions at your own peril and risk!

First, you need to close all LG-related programs on your computer and make backups of all important data: contacts, messages, call logs and others.

1. Download three archives from here: download 3pak.zip

Option 1. Install B2CTools LG (B2CAppSetup.zip).

Unpack KDZ_FW_UPD_EN.zip (for example in C:\KDZ\).

Install msxml.msi (located in the KDZ_FW_UPD_EN.zip archive).

Unpack WindowsEnabler.zip into the KDZ folder (for example, in C:\KDZ\WindowsEnabler).

Option 2. Simpler. You can use a modified KDZ program that does not require WindowsEnabler: download KDZ_FW_UPD_EN.rar

3. Launch LG Mobile Support Tool from the desktop (or from the archive of the same name B2CAppSetup.exe). In the window that opens, select “Install USB driver”, find LGP880 in the list and double-click to start its installation.

After installation, check the tray again and, so that the updater can see the device, close everything related to LG.

4. Turn off the mobile device (it’s better to remove the battery, although for many it works with the battery). Insert the USB cable without pressing the Power button, just hold down the Volume Down button). “S/W Upgrade” should appear on the screen.

The best solution is to remove the battery, then insert the cable while holding “vol-”. When “S/W Upgrade” appears, return the battery to its place.

5. Open Control Panel on your computer, select Device Manager, then Modems. In order for the updater to see the device, you need to disable “LGE Mobile USB Modem” in the list of modems.

If the modem is not detected, then you need to repeat step 4 until it appears.

6. As an administrator, you need to run KDZ_FW_UPD.exe in option 1 or the program downloaded from the link in option 2.

7. If you use option 1, you must run Windows Enabler.exe as an administrator

When you left-click on the icon that appears in the tray, the word “on” should appear.

8. For option 2, by analogy with the instructions for option 1, return to KDZ, click on the yellow folder icon and select the pre-downloaded file with the firmware we need.

Select “3GQCT” in the “type” field, and “DIAG” in the “phonemode” field

9. Without changing anything else, click on “Launch Software Update”. The phone should automatically reboot. There will be no reaction on the device screen for about 5-7 minutes. Next, in the program window in the “Update process” section, incomprehensible hieroglyphs will begin to appear - all this is normal.

“Incomprehensible hieroglyphs” will appear constantly. if after more than 5 minutes nothing “moves”, then something went wrong and the process needs to be restarted (return to point 2).

If the process stopped in the log with “unpacking KDZ”, then, most likely, unpacking the firmware is impossible due to damage or inconsistency of the KDZ file. Here you can try changing the USB port.

If it hangs on “...param=...”, it means that the process has stopped for a number of reasons. Here you will also have to restart the process (return to point 2).

If you end up in “Bootlap” after flashing (the mobile phone is constantly rebooted), you need to turn off the device, remove and put the battery back in place, and you need to hold down the power button until recovery appears on the display. Here we click on “wipe data/factory reset”.

It is very important to remember that “wipe data/factory reset” erases all personal data. Although they will already be deleted after flashing KDZ.

Sooner or later, TV software ceases to be modern and relevant. Since the release of a certain model into wide production, the manufacturer continues to upgrade the software of an already used brand, creating firmware versions that correct failures and stabilize the functioning of the TV. Therefore, for owners of LG TVs, the question of how to properly flash an LG TV, the procedure required for this, and where to get the updated version of the software never loses its relevance.

We warn you in advance that updating the TV software yourself if done with errors will result in the TV losing its functionality. All manipulations carried out with the blue screen operating system by you yourself are risky. To ensure that the firmware of your LG TV is successful, strictly follow the rules and recommendations below.

The information in this article with detailed step-by-step instructions and illustrations will allow you to install the software on your TV quickly, conveniently and reliably.

Step one - determining the exact modification of the TV

First, determine the modification of your blue screen. This is necessary to search and select the desired software product. Software for a different TV model may not be compatible with your TV. To find out what modification your LG TV is, you need to:

On the remote control press " Menu", then - " Customer support"(red button with a white dot in the middle). Next, select the item " Product/service information" In the line " Model/Type» read the full brand name. In the line " Software version» look at the current software version.

On the remote control press " HOME", select the column " Settings", chapter " Support", line " Product/service information" In the line " Model/type» you will read the exact brand name of your TV.

Step two - finding suitable software

Knowing the exact brand of the TV, start searching for the software suitable for its firmware. There are several ways to accomplish this task. Today there are a huge number of sites on the Internet that provide software products for flashing LG TV firmware. But, most likely, the result of using such a dubious software product will be disastrous - partial or complete breakdown of the TV. It's better to look for software for your TV on the official LG page. To do this:

Step three - update the software on your LG TV

To update the LG TV software, prepare a USB flash drive. So, you need:

Remember, you cannot:

Remove the USB flash drive from the TV until the update operation is completed

Turn off the TV until the software update is completed

Turn off the power until the software update operation is completed

Do not install software updates on the TV “incrementally”; if there are two or more updated files, update from the “younger” version to the “older” one.

Conclusion

We hope that this instruction for LG TV firmware will allow you to quickly and easily update the software of your TV. Remember that only using software from trusted sources is guaranteed to protect your device from problems.

Just like with all multifunctional devices, the firmware of an LG TV must be updated periodically. Smart TV technology turns an ordinary television receiver into a kind of analogue of a computer or smartphone through which the user can access the Internet. Since technological progress never stands still, manufacturers are constantly working to eliminate identified errors in older versions of software, improve the interface, and expand functionality. Over time, the firmware becomes more and more outdated, and the TV may not work correctly.

In addition to the release of updates, you may need to flash your LG TV due to any operational failures, for example, if the channel settings are lost after each shutdown of the device. This may indicate that the firmware has failed.

You can reflash the tuner yourself in automatic mode or from a flash drive (a little longer, but, in general, not as difficult as it might seem). If you are unsure of your capabilities, it is better to immediately call a specialist. Here it should be understood that haste and failure to follow the sequence of the entire procedure can lead to damage to the device, and repair will cost much more and take more time.

Where to get the necessary files

Before updating the firmware of LG TVs, you need to accurately determine the model of your device. You can view this information on the back panel of the TV, in its technical data sheet, or search in the menu via the remote control. Next in the same menu you should find out which firmware version is currently installed. You can find out if there is a newer one on the official website of L-G.

Update files host many network resources. However, it is not recommended to download them from unverified resources, as there is a high risk of damaging the system with viruses or errors.

Before flashing the TV, not in automatic mode, but via USB, manually, you need to do the following:

We go from a laptop or computer to the official website of LG;

Find the search bar at the top of the monitor and use the keyboard to enter the name of your TV model into it, press the Enter button;

We look through the search results, go to the support tab and select the section with programs;

Select the file of the required update, which will be called Software File Version (version number in the format xx.xx.xx);

Further steps are even simpler, and require only a little time and concentration on the process. If everything is done in strict sequence, there will be no problems.

Installing a new version using your hands

To flash an LG Smart TV firmware from a flash drive, the sequence of actions requires:

Download the update file in archive format to your computer and unpack it (the result is an .epk file that cannot be renamed;

If, when unzipping, there is not one file, but several, this means that the user previously missed some updates and now must install them strictly in sequence from the lowest version to the highest (if you break the sequence, the tuner will not work correctly);

Format the USB drive, open it, create a folder called LG_DTV and copy the previously downloaded and unpacked .epk file for Smart TV into it (nothing else should be written to this flash drive);

Disconnect the drive from your computer and insert it into the TV tuner (if there is a USB port directly on the TV, then we connect the drive there);

Further actions are no longer carried out manually, but automatically; the necessary information for updating is read directly from the flash drive.

The LG TV update and its process will be displayed on the TV screen regardless of whether there is a connected tuner or a drive inserted directly into the TV port. When the process is completed, a corresponding notification will appear. You can check the status of the new firmware in the menu through the same remote control.

Automation and important rules

As you can see from everything that was said earlier, you don’t need to do anything super complicated to reflash your LG Smart TV - download, copy, insert a USB flash drive into the tuner and wait. However, there is an easier way to change the current version if the TV has stable support for Internet access - automatic.

To do this, you don’t need to have a TV or laptop at hand, you don’t need removable storage devices, you just need to have an Internet cable with good data transfer speed or Wi-Fi to which the TV is connected, and a remote control. It is important to remember some rules that should not be broken:

After starting the update until it is completely completed, it is strictly forbidden to turn off the TV and remove the flash drive if it is in use;

You cannot disconnect the TV from the power supply until a window appears on the screen indicating the completion of the firmware process;

It is necessary to update the current version only from smaller to larger in order to avoid technical malfunctions.

Automatic firmware update is carried out by a special firmware. From the remote control you need to enter the menu, select the SETTINGS section, then the Support tab. In the window that opens, you need to click on software update, where the current version will immediately be displayed. Click check for updates, if available, click Update.

As with most modern TVs, there are two ways to update the firmware on LG TVs:

1 Updating LG TV software from the Internet;

2 Firmware update from USB flash drive.

I propose to consider each option step by step.

Updating LG TV software from the Internet.

This method, in my opinion, is the simplest and most convenient. All you need is an LG TV with Internet access, and it doesn’t matter how the Internet is connected using LAN network cable or WiFi. Next, you need to go to the TV settings; to do this, click the “Settings” button if you have a regular remote control.

Or the "Input" button

and select the gear icon if you have a Remote magic remote.

Click on the "Check for updates" button.

If updates are available, the TV will prompt you to download and install them. If you want to automate the TV update process, you can check the "Allow automatic updates" checkbox.

If your TV has the latest software installed, you will see the message “No updates found.”

Thus, by pressing several times on the remote control, you can easily update the LG firmware.

Updating LG TV from a USB flash drive.

This method is suitable if your TV does not have Internet access. Its whole essence is that you download the firmware to a USB flash drive from the official LG website, then connect this flash drive to the TV and install updates.

Before you start updating your LG TV, you need to find out the exact model of your TV and the installed software version. To find out the TV model, look at its back panel, there will be a sticker indicating the model. If you can’t get close to the TV from behind (hanging on a bracket), then you can go to the TV settings in the “General” - “TV Information” menu and look at the model of your TV, and there you can also see the version of the installed software.

Once you have found out your TV model, go to LG official website and enter it in the search bar.

Open the "Software Update" tab and if there is a newer firmware version, download and unzip the downloaded archive.

To update, you will need a USB flash drive with a capacity of at least 1 GB. Transfer all information from the USB drive and format it . After this, create a folder on the media called LG_DTV and transfer the firmware (file with EPK extension) to the created folder.

Turn off the TV and connect the USB flash drive to any USB port (if there is a “USB in service only” port, then you need to connect the flash drive to it). After turning on the TV, you will be asked to update it, select "Install".

The Android operating system today is very popular among owners of various gadgets - phones, tablets and others. That is why manufacturers are trying to monitor the process of updating the Android version and implement their support in their models, at least flagships. Therefore, you need to know how to update Android on your phone yourself.

Developers of any system strive to improve their product. Android is no exception to this. Updating the system improves the performance of the gadget and eliminates errors and shortcomings of previous versions. All this leads to improved performance of the smartphone in general. Android updates are often noticeable even visually when the interface changes and some new configurations appear.

There are micro and macro updates. Small ones often weigh no more than 70-100 MB, but macro ones can weigh on average 500 MB. To update the Android version, it is advisable to have a Wi-Fi connection or unlimited Internet. Although the latter can significantly delay the entire process.
If the auto-update feature is enabled in the phone settings, the user will simply be notified at the end that the operating system has been updated. Self-installation is relevant in the following cases:

there is no auto-update, information about a new version has appeared;
The current version does not support existing or new applications on the phone;
There was a need to roll back the system.

For example, my LG L90 smartphone has Android 4.4 as its native version. But after the first turn on, it was updated immediately to the latest version, or rather to 5.0.2.
We will consider those cases when you need to update the software manually.

Update methods

Via phone

How to update the Android version with only a phone?

This method, in my opinion, is the simplest. To update using it, you need:

In the phone settings, select the “General” tab;
tap “About phone”;
select “General” again (I have duos, so it may differ);
you can view all information about the software version or immediately go to the “Update Center”;
here you can update applications that require it, or immediately the system;
by selecting the second item, we will see that you can check Android for updates, as well as enable/disable the ability to auto-update;
after selecting the check item, the phone warns that to carry out this operation the device must have access to any network except 2G (I had everything turned off);
After connecting to the network, it searches for updates, after which either a message appears about the relevance of the version, or the update begins.

The main condition for this method is a high level of battery charge so that the update process does not end in a force majeure event. You can even update Android 2.3 to 4.0 in this way.

Manual flashing

Micro and macro Android updates appear almost every day. Manufacturers do not always have time, and perhaps do not strive, to develop them for all models. Sometimes this takes a very long time, and the update may not arrive at all. How to make sure you don't miss out on improvements for your phone?

In such a situation, you can independently change the firmware of your smartphone via Recovery. To do this you need:

From the official website of the manufacturer of your device, download a zip archive with the firmware we need (check the version number and build date before doing this) and place it on the phone’s memory card.
Turn off your smartphone and go to Recovery. The login combination may be different for all phones. For example, on LG L90 it is “Power + Vol (up or down)”, on Motorola and Lenovo phones it is “Power + Vol up + Vol down”.
Select the “Apply update” item.
Now the item “Choose from sdcard” (“Choose from internal storage” if the archive was saved in internal memory).
Go to the desired folder, find the installed firmware file and run it.
After the installation process has been completed, you need to return to the main menu and from there reboot the device “Reboot system now”

Using a computer

How to update the operating system if there is no access to Recovery?

In this case, you need to have a cord to connect your smartphone to your PC, as well as a disk with drivers for the official service program for a certain brand of phone. The latter may be missing, but this program can be downloaded.

Let's look at this method using LG phones as an example. For them you can download the KDZ Updater application. The necessary conditions are:

download the Android system update (archive KDZ_Update.zip);
mobile phone charging level is 50% or higher;
LG drivers installed;
availability of a firmware file for a specific model in KDZ format;
absence of any other program for LG (not counting the driver).

The procedure for updating software for Android through this program is as follows:

Unzip KDZ_Update.zip and transfer it to your computer’s system drive. Move the firmware file there too. Run the msxml.msi file from the archive.
Through the phone settings, enable USB debugging on LG. In my case, the fifth Android did not immediately provide such an opportunity. This does not mean that it is not possible to enable it. First, you need to find the build number in the phone information and click on it 5 to 10 times in a row. The notification “You are now a developer” will pop up. Now the “Developer Options” item will appear in the general settings. There you will find the “USB Debugging” item.
Then turn off the device and remove the battery (for some LG phone models this is necessary for flashing).
Press and hold the “Vol down” button and connect your smartphone to the computer. The message S/W Upgrade should appear. If it is not there, you should repeat everything, but with the battery inserted. Next, the battery must be in the phone in any of the cases.
Go to Device Manager on your computer. Disable LGE Mobile USB Modem.
In KDZ Updater, in the type field, you need to select 3GQCT from the drop-down list, and in phonemode - DIAG.
In the KDZ file field we enter the path to the firmware file or simply select it through the open files button.
If everything was done correctly, the user will see that the system is updated.

You should use the same method and, if necessary, roll back the Android version to any of the previous ones. Do not forget that the software update will lead to the fact that all files, contacts and SMS stored in the internal memory of the phone may be lost.
