      Drivers and programs

      Files

    Attention!

    This method requires an unlocked bootloader, because it includes custom recovery firmware.

    Installation instructions

      Create a folder in the root of the C:\ drive named " Android».

      Install drivers on your device.
      To do this you need to go to the folder Flashtool installations(by default in the root of drive C), go to the “drivers” directory and run “Flashtool-drivers.exe”, first (for Windows users Vista/7) making it compatible with Windows XP. During installation, select " Xperia M2 Device Driver », « Flashmode Drivers" And " Flashboot Drivers" After installation, restart your computer.

      Enable installation of applications from unknown sources.
      To do this, go to the menu “ Safety"from the system settings and activate the item " Unknown sources».

      Launch Flashtool.

      Switch the phone to firmware mode.
      To do this, you need to turn off the device, while it is off, hold down the Volume Down button and connect the phone to the computer via a USB cable. Launched Flashtool should identify the connected device.

      In the program (Flashtool), click on the start firmware button (with the lightning icon). In the window that appears, select the mode Flashmode, then the bootloader file. The program will prepare the file and the installation process will begin.

      If the operation completes successfully, the program log will contain the lines “ Flashing finished" And " Please unplug and start your phone" This means that the firmware is complete and the phone can be disconnected and turned on.

      Now you need to turn off the phone and connect it to the computer via a USB cable while holding down the volume up key. The smartphone will reboot into fastboot mode, and the LED will light blue.

      Open a command prompt and go to the created folder Android team « cd c:\Android\"(commands are written without quotes).

      Check the availability of the device in bootloader mode.
      To do this, enter “ fastboot -i 0x0fce getvar version" The response will display, for example, “version: 0.5” - this means that the phone is connected correctly. If the response is “waiting for device”, you need to check the status of the USB connection and reinstall the drivers if necessary. If “getvar: version FAILED...” is displayed, you need to disconnect the USB cable, hold down the volume up button, reconnect the cable and enter the command again.

      Provided that the device is detected in bootloader mode, enter “ fastboot flash recovery recovery.img" Once installation is complete, the USB cable must be disconnected.

      Enter recovery mode.
      To do this, you need to hold down the Volume Down button, then press and hold the Power key until it vibrates. After the SONY logo appears on the screen, release the Volume Down button.

      After entering the recovery menu, a request to modify the /system section will appear on the screen, which you must agree to by swiping from left to right.

      If a request appears to obtain superuser rights, you must also agree to it. The device will reboot into the system.

      After downloading, find and launch the application SuperSU Installer, in which you need to press a button Play. An app store will be opened Google Play, where you need to install/update SuperSU app. After the update, the SuperSU application cannot be opened.

      Then connect your phone to your computer using a USB cable.

      Make sure that the computer finds the device via ADB.
      To do this you need to enter " adb devices" to the command line. When a request appears on the phone for permission to debug via ADB on this computer you must press " Ok", while selecting the item " Always allow from this computer" If the device is visible, the text “ List of devices attached" and a list of all devices (for example, xxxxxxx device). If instead of “device” it says “offline” or the list is empty, then you need to update ADB, check the drivers/cord, change the USB port/computer.

      At the command line enter " install.bat».

      When prompted for superuser rights on your phone, press Allow.

      After the operation is completed, the command line will read “ Press any key to continue" The smartphone can be disconnected from the computer

    How to install and enter recovery on Sony Xperia - recovery Philz CWM and TWRP
    For even greater comfort in interacting with your smartphone and expanding its capabilities, the user may need root user rights, as well as recovery mode. Today's instructions will be devoted to how to install recovery on Sony Xperia and how to log into it. Nice bonuses:
    There is no need to unlock the bootloader.
    Several custom recoveries will be installed at once - Philz CWM and TWRP on Sony Xperia.
    The recovery itself (aka recovery mode) is a kind of environment that can be launched before the smartphone system boots and inside it perform various useful actions: install updates, various modifications, clear the smartphone data, reset it to factory settings, reboot the smartphone, reset the cache, do system backup and perform recovery, mount partitions.

    As you can see, some functions are really useful. In addition, if your smartphone freezes and does not turn on, what exactly can you try to do through the recovery mode? fast recovery systems, for example, reset to factory settings with a complete system clean if it is not possible to use PC Companion. Personally, I needed this mode for installation different modifications on your own Xperia smartphone Z2: sound mod to improve the sound in headphones, camera with a new interface, boot animation from Z5 models and others. Despite the fact that installing recovery is not at all difficult, we still want to warn you and remind you that we do not bear any responsibility for the actions you take.
    This method is good because it works on smartphones with a closed bootloader, but prerequisite is the presence of root rights (instructions for easily obtaining them).
    Don't forget that your smartphone must have USB debugging enabled. First you need to download necessary files XZDualRecovery. Follow the links below and find the desired archive for your model: download the archive with the ending “RELEASE.installer.zip” for version XZDualRecovery 2.8.21 – Link or “RELEASE.combined.zip” for version 2.8.25 – Link. If you don’t see the archive for your model, then look for it in the profile topic for your smartphone on the 4pda forum.
    We unpack the downloaded archive and in the folder we see the following files:

    We connect the smartphone to the computer and run the “install.bat” file from the folder, after which a system window will open on the PC prompting installation. Enter the number “1” in it and press “Enter”:

    The connection with the smartphone will begin (perhaps at this moment a notification about debugging permission will appear on the smartphone, where you need to click “OK”), after which the download of recovery files will begin:

    In the next step, described in the window as “Step 3”, the Dual installation Recovery, check root rights and a message will appear that to continue the installation you need to press any button on the keyboard, which is what you do:

    Again we observe how files are copied and installed. After successfully completing this procedure, you will again see a message about the need to press any key to continue, and at this time the smartphone has already started to reboot:

    The smartphone will reboot in one of the custom recovery modes: Philz CWM (first screenshot) or TWRP (second screenshot):

    To reboot your smartphone in the first case you need to select Power Options – Reboot or Power off, and in the second case Reboot – System or Power off. You can read more about all the menu items and the capabilities of each mode on the Internet by simply entering their names in the search engine.
    How to enter recovery on Sony Xperia
    If the smartphone is turned off and you want to get into recovery mode, you need to press the power button to turn on the device and as soon as the Sony logo appears, press up to two vibration signals:
    volume up button to enter Philz CWM.
    volume down button to enter TWRP.
    Another nice thing is that on our smartphone we will have the NDR Utils application for managing interaction with modes, which has an icon with a devil. In it you can choose which of the custom recovery will be preferable for logging in (for me it’s TWRP), and also quickly turn off the smartphone, reboot the system, reboot into recovery, fastboot or flashmod mode. Thus, if you are working with a smartphone and want to immediately reboot your Sony Xperia into recovery mode, just go to this application, choose the required version and click “Reboot to Primary Recovery”.

    After this, the smartphone will immediately reboot and log into it. I tried to describe the entire process in as much detail as possible and I hope the instructions will be clear and useful.

    As with any operating system, Android has a special boot mode where the device turns on, but the system itself does not boot. This mode is called Recovery Mode, or in Russian recovery mode. This mode is available in any Android device and allows you to reset parameters, change firmware, restore firmware from backup copy or simply in case of freezing. It is noteworthy that, unlike root rights, using Recovery Mode is not dangerous, and therefore is not blocked by the developer in any way. This function can be used by absolutely everyone and completely officially. Let's take a closer look at how to enter recovery on any device running Android, and what each menu item is responsible for.

    Recovery Mode provides access to the system functions of the device

    Ways to enter Recovery mode

    On the device itself

    Standard method. The principle of entering Recovery Mode is the same for all devices - when you turn it on, you need to hold down several buttons. Most often this is volume up, but the following options may also occur:

    • Samsung - power on + volume up + Home.
    • LG - power on + volume down.
    • Google Nexus, HTC - power on + volume down, then tap Recovery.
    • Certain Lenovo, Motorola models - power on + volume up + “Home”.
    • Sony - power button, after double vibration, hold down the volume up.

    If for some reason you enter Recovery Mode standard means If it doesn't work, try checking the instructions. The listed combinations are valid in almost all cases and will work both to enter the standard recovery menu and the custom one. In addition, you can run it even when the tablet does not boot or the system freezes.

    If you have root rights you will need installed application Terminal Emulator(https://play.google.com/store/apps/details?id=jackpal.androidterm). After installation, you will need to enable superuser rights and enter two commands: first su and then reboot recovery. The device will reboot.

    Via computer

    A prerequisite is that USB debugging mode is enabled (Settings - For developers - USB debugging, or select the appropriate item when connecting to a PC). Therefore, if this mode was previously disabled, the tablet will not start and you will not be able to use it.

    You will need a program ADB Run(http://cloud-androidp1.in/Android/PC/Project_Site/AdbProgramm/), cable and working device.

    1. Connect your device to your computer.
    2. Run ADB program Run.
    3. In the program menu, press 4 and then 3 in sequence.

    The device will reboot into Recovery Mode. You can perform the procedures you need.

    How to use Recovery Mode

    As we have already said, there is both a standard recovery and a custom or custom one. Many experienced users claim that the capabilities of the first one are quite scarce, so it is better to install the unofficial one. We'll talk about them a little later, but now we'll look at what Recovery Mode menu items you can find on your device.

    Install zip from sdcard- installation of an archive with updates saved to a memory card. Through this menu, root rights are obtained and the firmware is installed.

    Wipe data/factory reset - wipe data/reset settings to factory settings - complete cleaning system partition, reset all settings to their original state. All apps and settings will be removed, but your media files will remain intact. Used for critical errors system failures or when new firmware is being updated. Especially effective remedy in cases where the device does not turn on.

    Wipe cache partition- cleaning system cache- a system section in which temporary files and all program settings are stored. It is recommended to do this when the firmware is changed.

    Backup and restore - backup systems and restoration from previously created backups.

    Mounts and storage - for correct operation all sections of the system must be correctly mounted and connected. Often, this procedure is performed automatically, but sometimes something has to be corrected manually. You can also clear one of the partitions. We advise you to use this method only in case of specific need, otherwise file system will not boot and the tablet will not work.

    Advanced - additional settings, among which - reboot Recovery Mode, clear dalvik cache, reset permissions system applications. Most often used by professional programmers.

    Management, unless otherwise indicated, is carried out through (moving through the list) and power (selecting a menu item). In some cases, selecting is done with the volume up, and scrolling is done with the volume down. In any case, the system must indicate exactly how to manage menu sections. There are developments with touch control.

    Unofficial Recovery

    As mentioned above, standard Recovery Mode very often has several limited opportunities, therefore it is best to use third-party, unofficial developments. The most popular are two of them - ClockworkMod recovery(abbreviated CWM) and TeamWin Recovery Project(abbreviated as TWRP). Both developments have excellent functionality and allow you to very quickly and conveniently modify or change the firmware, obtain root rights, reset settings to factory settings, or restore a backup copy.

    CWM looks very similar to the standard one, only with a slightly different arrangement of menu items. Navigation through the menu is carried out using the volume buttons, and selection is made through the power button. There is a version with touch controls. Well, TWRP has an unusual tiled interface and is controlled via touch screen. You can navigate through the menu by pressing the display, and you need to confirm the action by swiping. Some Android devices have one of these recovery installed either by default or with the standard one. Installing and downloading custom recovery may differ depending on the model, so look for information in the sections about your tablet model on specialized forums.

    Conclusion
