Firmware

For Lenovo A3000-H, there are not a lot of firmwares that allow to use the device as a springboard for experiments with different versions of Android. There are only two systems that really work flawlessly, stable and therefore suitable for everyday use: an operating system from the manufacturer and a modified solution built on the basis of a more modern version of Android than that officially offered by Lenovo.

Method 1: official firmware

As a solution to the problem of restoring the software part of A3000-H, completely reinstalling Android on the device, as well as updating the system version, the firmware version A3000_A422_011_022_140127_WW_CALL_FUSE .

The proposed solution has a Russian interface language, there are no Chinese applications, Google services are available, and all necessary software components are available to make calls over mobile networks and send / receive SMS.

You can a file containing images to write to memory sections and other necessary files at the link:

Official Firmware for Lenovo IdeaTab A3000-H Tablet

    1. We unpack the archive with the official software in a separate directory, the name of which should not contain Russian letters.
    2. Launch FlashTool.
    1. Add a file to the program that contains information about the addressing of the starting and ending blocks of the sections in device memory. This is done by pressing the button "Scatter-Loading" and then selecting the file "MT6589_Android_scatter_emmc.txt" located in the firmware images directory.
    1. Check the box "DA DL All With Check Sum" and click "" .
    2. In the prompt window that contains information that not all sections of the tablet will be written, click "Yes" .

    4. We connect the USB cable to the completely turned off tablet, which is connected to the PC port, which should lead to the definition of the device in the system and the automatic start of the process of overwriting the memory of the device. The procedure is accompanied by filling in the yellow color of the progress bar located at the bottom of the FlashTool window.

      If the procedure does not start, without disconnecting the cable, press the reset button ( "Restart" ). It is located to the left of the SIM card slots and becomes accessible after removing the back cover of the tablet.

    5. After the firmware procedure is finished, the Flash tool will display a confirmation box « OK» with a green circle. After its appearance, you can disconnect the cable from the tablet and start the device by holding down the key "Switched on" a little more than usual.
  1. The firmware can be considered complete. The first launch of the reinstalled Android takes several minutes, and after the welcome screen appears, all that remains is to select the interface language, time zone, and determine other basic system parameters,

    after which you can restore the data

    and use a tablet with the official version of the system software on board.


Further. Custom recovery

Many s of the model in question, who do not want to switch from the official version of the system to third-party solutions, use the modified TeamWin Recovery (TWRP) recovery environment for various manipulations with the system software. Custom recovery is actually a very convenient tool to perform many operations, for example, backing up partitions and formatting individual memory areas.

The TWRP image and the Android application for installation on the device are in the file, which can be ed from the link:

TeamWin Recovery (TWRP) and MobileUncle Tools for Lenovo IdeaTab A3000-H

The effective application of the installation method requires the super rights obtained on the device.

    1. We unpack the resulting file and copy the TWRP image "Recovery.img" as well as the apk file, which is used to install the MobileUncle Tools application, to the root of the memory card installed in the tablet.
    1. Install MobileUncle Tools by launching the apk file from the file manager, and then confirming requests from the system.
    2. We launched MobileUncle Tools, we provide the tool with root rights.
    3. We select the element "Recovery update" in the app. When scanning the memory, MobileUncle Tools will automatically find the environment image "Recovery.img" on the microSD card. It remains to touch the field containing the file name.
    4. When asked about the need to install a custom recovery environment, we respond by clicking "To accept" .
    5. After transferring the TWRP image to the corresponding section, you will be prompted to reboot into custom recovery; We confirm the action by clicking on "To accept" .
  1. This will that the recovery environment is installed and starts correctly.

Subsequently, the loading in the modified recovery is carried out in exactly the same way as when starting the "native" recovery environment, that is, using the hardware keys "Volume-" + "Switched on" , pressed simultaneously on the powered off tablet, and selecting the appropriate item in the device's boot modes menu ...

Method 2: modified firmware

For many outdated Android devices whose technical and system software updates have already been discontinued by the manufacturer, the only way to get updated versions of Android is to install custom firmware from third-party developers. As for Lenovo's A3000-H model, we have to it that unfortunately many unofficial versions of the systems were not released for the tablet, as for other technically similar models. But at the same time, there is a stable custom operating system, built on the basis of Android KitKat and with all the functions that most s need.

You can the file containing the files for this solution for installation on a tablet by following the link:

Android 4.4 KitKat based custom firmware for Lenovo IdeaTab A3000-H

Installing custom Android 4.4 on Lenovo IdeaTab A3000-H is done in almost the same way as flashing the official software package i.e via the SP Flash tool, but there are some differences during the process, so we continue! instructions carefully!

    1. Unzip the KitKat file ed from the link above into a separate directory.
    2. We launch the flasher and add images to the program by opening the scatter file.
    3. Establish the brand "DA DL All With Check Sum" and press the button "Firmware-Upgrade" .

      It is important to install the modified firmware exactly in the mode "Firmware update" , and not "" , as is the case with official software.

    4. We connect the A3000-H off and wait for the processes to start, as a result of which the installation of a relatively new version of Android will take place.
    5. The procedure carried out in the mode "Firmware update" involves preliminary reading of data and creating a backup of individual partitions, then - formatting memory.
    1. In addition, the archive images are copied to the appropriate sections and the information is restored to the formatted areas of memory.
    2. The above operations take longer than the usual transfer of data to memory, as is the case with official firmware, and are completed with the appearance of a confirmation window "Firmware update OK" .
    3. After the successful firmware confirmation appears, disconnect the device from the USB port and start the tablet by long pressing the key "Switched on" .
    1. The updated Android initializes fast enough, the first launch after installation will take approximately 5 minutes and will end with an on-screen demo with the choice of the interface language.
  1. After defining the basic settings, you can proceed to retrieve information and use the tablet by running the highest possible version of Android for the model in question: 4.4 KitKat.
