Sometimes the users want to flash a new firmware in case of getting their device soft brick, or sometimes just to improve the performance. While the OTA updates take a long time to reach different regions, some of the users also look for a way to flash latest firmware on their devices before it makes a way to their devices through OTA updates. Rooting the phone is another option that allows the tinkering on device, flashing custom roms, kernels and a lot more things are there that can be flashed in an Xperia device, but wondering how? Well, Sony has a Flashtool for its Xperia line up.

Sony Flash Tool

Flashtool is a light software, that allows the flashing through ftf (flashtoolfirmwarefiles). It becomes handy if you are struck somewhere. In today’s tutorial we will be having a look on the detailed guide to use Flashtool.

As this is the main tutorial for Flashtool, we will be having a look on the method to flash firmware in an Xperia device.

Before we begin you need to download and install the following.

      • Go ahead and download the Flashtool and install it – Download it Here: Link 1
      • You need to install Sony drivers, get the Sony PC Companion: Download it Here.
      • Mac users may download Sony Bridge: Get it Here.

Understanding & Using the Flashtool:

      1. After you’ve downloaded and installed the Flashtool, you’ll get a folder named ”Flashtool” in your C: drive, or the drive which you selected while installation.
      2. Here you can see the folders like Custom, Devices, Firmwares, Drivers.
      3. The devices folder contains the supported devices, firmwares is the folder where you will place the .ftf file to be flashed in your phone, while the drivers folders has the Flashtool-drivers for all Xperia devices, you may install drivers through Flashtool in case you face any difficulty at the time of flashing.
      4. Access the Flashtool-drivers and install Fastboot & Flashmode drivers as well first.Screenshot_2 
      5. After the drivers have been installed, you’re good to go with Flashtool now. The first thing you need to do is, you need to download your desired file, that you are going to flash. It may be a firmware, a kernel or a root file, but it should be in .ftf format. Download the file and place it in ‘‘Firmwares” folder that is is in Flashtool folder.Screenshot_6
      6. Run the Flashtool.exe now, access it from the installed programs or from the same folder under drive C:.
      7. In Flashtool, hit the lightening button on the top left, select whether you want to run Flashmode or Fastboot mode. Flashmode is the one you’ll need most probably while you’re trying to install an ftf file, select it and press Ok.Screenshot_1
      8. Select the firmware or the file that you want to flash here, and make the other selections accordingly, below is an image showing the procedure for a firmware’s ftf file. After you’ve settled it up, hit the Flash button at the bottom now, it will start loading the ftf file and show you logs. Screenshot_3
        Screenshot_4
      9. As soon as the file is loaded, you should see a pop up, prompting you to connect your device to the PC in Flashmode.
        Screenshot_5
      10. Now, turn off your device, and connect to your PC using the original data cable while keeping the Volume down key pressed. You should see the Green LED on your device. This is for flashmode, in case you want to connect your device in fastboot mode, you need to connect it while keeping the Volume Up key pressed and you should see the Blue LED now. For older Xperia devices, the back key will work for Flashmode while the menu key will work for fastboot mode.

      11. After you’ve connected your device successfully, the Flashing will start, wait and sit back while the flashing gets completed. You should see the logs now, as soon as it is done the ”flashing done” will appear at the bottom.

That’s All! We hope that the tutorial was easy for you to understand. Any difficulties or queries you got? Feel free to leave us a comment, We will try our best to help you out.

    • Usama Mujtaba

      @quesitoquesitoq:disqus you got to keep the volume down key pressed when you flash the firmware. Do not leave the key :) this is happening because you leave the key after it picks up your phone.

      • Quesito Quesito Q

        Thank you very much.works perfectly. :-) :-)

    • Usama Mujtaba

      @sheikhalamin:disqus You need to install Flashmode drivers first. Please read the flashtool guide carefully.

      • Atul Tiwari

        There is error in installing drivers from the file……
        suggest someway

        • Usama Mujtaba

          @atul_tiwari:disqus you’re using windows 8? If so then you will have to disable Signature Verification first.

  • bitter

    works perfectly thanks again but i forget to backup all my data hahaha :d

    • Tomoms

      how funny.

  • Bradley Hadwick

    Flashtool on Mac won’t recognise that my phone is connected in flashmode or fastboot mode. I have the relevant light on my LED, and Sony Software recognises flashmode fine when doing a “repair”. I used to use flashtool and when connecting in flashmode, even though no options to flash had been selected, it used to still register the device as “connected in flash mode”. I did try to root the handset via vRoot and Root360, but these both failed due to being on 4.3 version .290
    Has this somehow broken my flash mode?
    I have “repaired” through Sony Mac software, and still the issue persists.
    Any help would be appreciated!

    • Usama Mujtaba

      @bradleyhadwick:disqus this flashtool will not work on MAC. please try using windows.

  • Varadha Raju

    Hi Bro, I have Xperia SP with 4.3 android version, could you help me to downgrade to 4.2?
    Basic outline steps should be fine :)

    • Tomoms

      You can’t. Android 4.2 was never released for Sony Xperia SP. You can downgrade to android 4.1

  • Peter

    I can’t install the drivers… Fastboot and Flashmode it shows me an error!

    • Usama Mujtaba

      @disqus_ON7vIXGgEP:disqus you’re probably running Windows 8. please disable driver signature verification and then install Fastboot and Flashmode drivers.

    Hello,
    please help
    i flashed my device Xperia U + rooted + BLU but its stuck; when i turn it on i can only go to CM .. how can i restore my device ??

    • Usama Mujtaba

      @disqus_aQgoTp7Lvi:disqus flash stock ftf in your Xperia U and the problem will be solved. You need to find stock ftf and flash using Sony Flashtool. And it’s not CM it should be CWM recovery. or You’ve flashed an invalid custom ROM based on CyanogenMod (CM)

      • Karim

        I Downloaded ST25i_6.1.1.B.1.100_Sony.ftf when i try to flash it i get error:

        09/057/2014 19:57:54 – ERROR – (X10flash.java:523) – Error in processHeader : 22 : The device does not recognize the command.

        09/057/2014 19:57:54 – ERROR – (X10flash.java:524) – Error flashing. Aborted

        I excluded the (system) flash .. it flashed correctly but my phone didnt boot ..how can i flash the system ? or maybe u can give me a link ..

        regards

        • Usama Mujtaba

          @disqus_aQgoTp7Lvi:disqus make sure that your device is properly connected and you’ve installed flashmode drivers properly and drivers for your device as well. Do not leave the volume down key until the flashing is done. You may find another stock firmware and give it a try.

    • http://UsamaMujtaba.com Usama Mujtaba

      @disqus_0zVjKBt5Ey:disqus those are multiple and different files. You will flash your desired one FTF file or others depending on your choice. I’ve used those in images to help the people better understand this tutorial. I guess you’re mixing it up.

    @carlodioquino:disqus what are you trying to do? I don’t find anything wrong with this log..

  • Prashant Chouhan

    Thanks bro!! You are the life saver. after installing the kitkat update my xperia sola’s navigation keys(home,menu,back) are not responding. All i want to return to my original GB version until i find a stable kitkat custom rom so that i can use my device then.

    Do you know the stable kitkat rom.

    i installed http://forum.xda-developers.com/xperia-u/sola-development/rom-cyanogenmod-11-t2743059 but my nevigation keys din’t work. do you know any stable kitkat rom out there??

    • http://UsamaMujtaba.com Usama Mujtaba

      @prashantchouhan:disqus you can return to GB using the guide above. About a stable kitkat custom ROM, I won’t be able to give you any, as custom ROMs are always like this.. you have to compromise something in order to make them work on your device. My suggestion is to stick to stock ROM as long as there’s no good custom ROM around.
