Install TWRP and Root Sony Xperia Z3 on Marshmallow Firmware


Sony Xperia Z3 was Sony’s second flagship for 2014. All in all a great device for the time but it is no slouch today either even as it is reaching towards its 3rd year since launch. The device has also been showered love by Sony with two full version Android updates. The Xperia Z3 was also all set to receive its third full version Android upgrade to Nougat, however, thanks to some Google mess, not only the Z3 but also the Nexus 5 couldn’t officially get updated. If you’re a Z3 user, now is not very late to root your device and travel the dark side. Here we will show you how to root Sony Xperia Z3 running on the official Marshmallow firmware from Sony and install a custom recovery on the device.


  • Xperia Z3 running the official Android 6.0.x from Sony. (.575 or .291 firmware)
  • Enabled USB debugging
  • A PC
  • Unofficial Sony flashtool by Androxyde. If you don’t have it, you can download it from here. In case you have no clue about how to set up the flashtool, follow our guide here after you have downloaded it.
  • ADB installed. In case you don’t have ADB installed, take a look at our guide here.

Root Sony Xperia Z3

  1. The process described here is valid for Xperia Z3 variants – D6603, D6653, D6633, D6646 and D6643.
  2. In case you are running the latest Marshmallow firmware, that is the .291 firmware, you will need to flash the kernel from .575 kernel.
  3. Download the correct .575 kernel for your device.
  4. Rename the .zip to .ftf and transfer the file to C:\Users\yourusername\.flashTool\firmwares\
  5. Click the flash icon and select flashmode.
  6. Select the kernel from the list of flashable firmwares. Once the kernel is flashed, click on the flash icon  and select flashmode.
  7. Select the kernel file from the displayed list and click Flash. Once the kernel is flashed, close flashtool. If you get a “loader.sin” error when flashing a kernel FTF, unplug the phone and try again. It should work after that.
  8. Power On your phone.
  9. We’d suggest that at this point, you restart your PC just to make sure all instances of flashtool and the ADB interface are closed.
  10. When your PC starts again, connect your Xperia Z3 to it again normally.
  11. Extract the recovery tool ( into a separate folder.
  12. Open the folder and double-click on install.bat
  13. If everything goes well, your phone should soon boot into the TWRP custom recovery.
  14. When in the recovery, flash the SuperSU zip like any other flashable zip.
  15. Once you’re done flashing SuperSu, don’t select Reboot System yet.
  16. Go back to the main TWRP menu and select Reboot>Bootloader.
  17. Now open flashtool again.
  18. This time flash the .291 kernel for your device also available for download above. Make sure you rename the .zip at the end to .ftf
  19. Disconnect and reboot your device now.

Your Xperia Z3 should now boot up and you should find the SuperSU app in your app drawer. When you want to reboot into recovery again, just reboot your device and press the Volume down button when the LED turns green.

  • Jan de Boer

    Hi yes everything worked well and also unrooting went fine!! Had to unroot because i had to send it back to Sony so that it could be repaired under their warranty service lol They didnt detect any root or warranty void!

  • Geovanny

    Hi Jan, is working well your cellphone after you have done the rooting process?…

  • Geovanny

    hello someone has worked well in the version Z3 6653 ?, I would like to know if it is true that the fidelity of the image of the camera is lost..

  • Open windows file explorer and enable “View extensions” option. You should then be able to edit file extensions.

    See the screenshot.

  • Elmo Riscanny

    whu i cant rename .zip to .tft?

  • Afina Saputra

    is the kernel for d6653 and d6603 same ? cause the flash tool only detect kernel for d6603

  • Maria S

    Hi,will i loose the drm keys with your method??

  • Jan de Boer

    Hi, everything worked fine, thanks for your guide!!

    Now that I recovered some deleted files I would like to unroot my device (remove recovery room, SU etc) Is reseting it back to factory settings enough or would I also need to flash a stock rom? (stock rom is the kernels you listed here?)


  • Vivek Tiwari

    The D6603-D6653 kernel works fine for D6646 and D6643 as well. The only difference between the devices is the baseband.

  • What’s your phone’s firmware version?

  • Javier Sánchez G

    “The process is valid for D6646, D6643″… Where are the files?? The kernel version for those models?? I’ve searched all web for rooting and installing twrp for D6646 and none can explain how-to-guide neither has the files!!

  • Kashif Mehmood

    Thanks, but what’s the difference b.w Sony Xperia Z3 Leo and Aries.

    What ROM should i download for flashing on my device D6603?

  • Kashif Mehmood

    Hi Vivek once more I need your support. Can u pls write a detailed step wise guide to install any good Nougat ROM. I almost messed up during last flashing of ROM lineage and got my device bricked. However, got rescued by re flashing stock ROM through flashtool and hence got unrooted.

  • Kashif Mehmood

    Thanks vivek, i think i am done with rooting process as #supersu icon has become visible in app drawer or tell me how can be sure about that my phone has become rooted. Further please also guide me to flash nougat rom in detail.

  • Vivek Tiwari

    It’s fine. The build number and other information displayed in the About phone section is actually associated with the build.prop file in the system. Flashing the kernel this way wouldn’t produce any change in the displayed information. But if flashing was successful, which is what I can see from the logs, you can proceed with the rest of the steps.

  • Kashif Mehmood

    Thank Vivek

    i did exactly the same you mentioned in step 4 – 6. kernel seems to be flashed now but when i see build number beneath kernel version in about phone it the same as previous 23.5.A.1.291.

  • Vivek Tiwari

    Hi Kashif, Sorry for the inconvenience. It seems there was some confusion in Steps 4 to 6. Follow these instead.
    4. Rename .zip to .ftf and transfer the file to C:Usersyourusername.flashToolfirmwares
    5. Click the flash icon and select flashmode.
    6. Select the kernel from the list of flashable firmwares.

  • Kashif Mehmood

    Sorry I am stuck at step 7 of rooting
    When clicking fastboot mode of flash tool there are multiple options to Flash kernel. Which one to select above tutorial is silent about that.

    Guidance would be much appreciated.
