Possible problems

1. The firmware process hangs... param=... - the process is frozen, repeat everything again (turn on, turn off, remove the battery ...)

2. Error unpacking KDZ- it is not possible to flash the firmware due to the inability to unpack the file. You can try connecting to a different USB port

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.

There are three constant stages in the firmware of any smartphone. The first is to look for an opportunity to get administrator rights on the phone. The second is installing CWM, an alternative recovery, from where everything else will be inserted. And the third is actually the firmware. This scheme is valid for everything except HTC - these devices also have to be unlocked first in order for the bootloader to give a chance to install something else. LG has very rarely mocked geeky customers trying to reflash their phone. The bootloader is open, even if the source code is inaccessible, but the official firmware has always been uploaded to the official servers with commendable efficiency. The fly in the ointment in mutual understanding between connoisseurs of the brand and companies has always been firmware updates - like other Android smartphone makers, there was no habit of supporting the phone with updates for three years, and the gap between the official update date and the promptly posted custom is too large to patiently wait for the weather from the sea.

Today we will flash the LG L5, a wonderful and slightly underrated device, with the latest firmware version, Android 4.4. The hardware component allows it, so why not? The first stage, as you remember, is rooting the LG L5. In an interesting way, it deprives the manufacturer of the need to fulfill its warranty obligations, and therefore, before carrying out all the procedures outlined below, make sure of two things - the warranty has already expired. You definitely need this. So, if the answer to both questions is positive, let’s proceed with the operation, dear colleagues. In the operating room, the first file to appear is root.bat and its assistants ( http://forum.xda-developers.com/attachment.php?attachmentid=1271318&d=1345457528). Download and extract it. The second assistant is a file with an absolutely meaningless name IS11LG_SystemBackupTest.signed.apk (http://forum.xda-developers.com/attachment.php?attachmentid=1272418&d=1345501542). Here you can transfer it to your phone and install it, after checking the boxes in the settings (unknown sources and USB debugging). Reboot your device after installing the program. Connect it to your computer, selecting the “charge only” mode, click root.bat that you downloaded just above. After the next reboot, install/update the Supersu application from the market. Reinstall Busybox. This completes the rooting stage. Look in the settings - information about the phone, what baseband you have (v20 should be there). If your communication module is v10, then you also need to flash the v20 version of the module for your phone version, otherwise the firmware will not fit into place correctly. You can download your version of the communication module in this topic (http://forum.xda-developers.com/showthread.php?t=2275969), no registration required. Move the archive to the memory card, we don’t need it yet, first install CWM.

Now it's time for recovery. Install from Google Play any terminal emulator that has the most positive reviews (for example, Android Terminal Emulator is recommended). Download the archive emmcapboot.rar ( https://mega.co.nz/#!dllRxbqa!LFVF4WBSNnqgJxTU_l2uHTwBFh9DO7zt7OZbnNkL2x8), unpack it anywhere, transfer the file from there to the internal memory of the phone, /sdcard. The path to the file should look like this: /sdcard/emmc_appsboot.bin. Now open a terminal emulator and type the following commands very carefully, without errors. We repeat, double-check at least three times that you have not made a mistake in any letter. Now we are changing the bootloader area and one wrong move will lead to irreparable consequences at home in the form of a worn out bootloader.

dd if=/dev/block/mmcblk0p5 of=/sdcard/emmc_appsboot.bin.bak (then enter, so we copy the original bootloader)

dd if=/sdcard/emmc_appsboot.bin of=/dev/block/mmcblk0p5 (input, this is how we remove the bootloader block)

Everything turned out great.

The third step is flashing the recovery firmware. Download CWM ( http://forum.xda-developers.com/attachment.php?attachmentid=1756759&d=1361709708), move it to the phone's sdcard (memory card, no folders) and write the following in the terminal:

Su (confirm administrator rights in the program window that will pop up on the screen)

dd if=/dev/block/mmcblk0p17 of=/sdcard/recovery.img.bak (copy the original recovery to the card, just in case)

dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p17 (install recovery on the phone).

After all this is over and your typing skills on the touch screen have improved, turn off your smartphone and press power on it, volume down and the Home button - after a couple of seconds with the phone turned off, you will be in recovery. There is a mount and storage item - switch to it, select mount sd, connecting your smartphone with a cable to the computer. Now download Android 4.4 firmware on LG L5 ( http://www.mediafire.com/download/xwmszevke13mrqe/cm-11-20131215-UNOFFICIAL-e610.zip), Google services Full or Mini to choose from (http://forum.xda-developers.com/showthread.php?t=2397942), as well as a custom kernel if your L5 is labeled as E612 (http://www.mediafire.com/download/w2wuoq5qo3e4qd4/lge-e610-v3.4.0-16-12-2013_08-13.zip). All this, without unpacking, needs to be transferred to a memory card. We go to the Backup item and make a backup of the official firmware - in order to avoid an adventure on the fifth point of the body. If trouble happens and the phone doesn’t want to work correctly after all the manipulations or you don’t like the firmware, return everything via restore to recovery. Everything is collected for the final operation. Click unmount sd in recovery. First of all, go through the items wipe (dalvik, cashe, data). Switch to Install and alternately install the communication module as zero (if you initially have v10), the first - the firmware file, the second - Google services. The third option is to install an alternative core if your phone is l5 E612. After which you can reboot via system reboot. The last surprise, if the phone does not boot even after 15 minutes, is corrected by re-entering the recovery and going through all the wipes a second time. Congratulations, Android 4.4 firmware on LG L5 is completely done.

Hello! Today we will talk about the LG E 612 smartphone. This is no longer a new device and is unlikely to be able to surprise the modern user with anything, a weak processor, a small amount of memory and a screen with a resolution of 320x480. But if you own this device, I recommend updating the software on it. The new firmware for the LG E612 Optimus L5 will allow you to correct shortcomings in operation, speed up the operation of this device and simply “refresh” it.

To avoid unpleasant consequences from this procedure, you need to carefully study the instructions below. And also be sure to save all your data and contacts on your computer.

Instructions for firmware LG E612

• Fully charge your smartphone battery.
• Download the firmware for the LG E612, as well as the program for uploading it to
  device. Unzip the archive with the program to any folder on your local
  disk.
• Download and install the drivers (you need to run the file as Administrator LGUnitedMobileDriver_S4981MAN38AP22_ML_WHQL_Ver_3.8.1.exe).
• After successful installation of drivers, you need to disable it in Device Manager LGE Virtual Modem.
• Turn off your smartphone.
• The following steps depend on the version of the Android operating system you already have installed. If this is version 4.0.3, then with the device turned off, hold down both volume keys and connect the phone to the computer via a USB cable. If the Android version is 4.1.2, then you only need to hold down the volume down key and connect it to the computer.
• Run the program as Administrator KDZ_FW_UPD.exe.
• In the program window, set the following settings: in the field Type choose 3GQCT, and in the field PhoneMode install EMERGENCY.
• Next, click on the open folder icon and in the window that opens, select our firmware file (V20G_00.kdz).
• Press the button Launch software update and wait for the firmware update process to complete.

Note

If your PC has the Windows 7/8/8.1 operating system installed, you may receive error messages at the end of the update process. Ignore them; the phone should update normally as a result.

But if suddenly, after uploading the new firmware, your device does not start, then install the msxml.msi file, which is located in the archive with the KDZ_FW_UPD.exe program and repeat the Android system installation process.

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 antiviruses 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 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 - reboot 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 to 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 condition, 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!
