How to Root the Sony Xperia Acro S running 6.2.B.1.96

The Sony Xperia Acro S saw itself update recently to solve some issues it had and the version number currently stands at  6.2.B.1.96.  Of those who used our guide to root their Acro S, some of you might have noticed that the update broke root access.  But now there is a solution to this and the guide below should help you get back your root privileges in no time.

I.  Before You Begin

1.  This procedure only works on the Sony Xperia Acro S running the 6.2.B.1.96 firmware only; do not try this if you have anything older on your device.

2.  As always, back up everything you care about and charge your device to 75% or more before you start.

II.  Necessary Downloads

1.  flashtool-0.9.11.0-windows.exe

2.  Xperia_Acro_S_LT26w_6.2.B.1.96_KernelOnly.ftf (Link available in this post)

3.  Xperia_Acro_S_LT26w_6.2.B.0.211_KernelOnly.ftf (Link available in this post)

3. DooMLoRD_Easy-Rooting-Toolkit_v18_perf-event-exploit.zip (or latest version, link available in this post)

III.  Flashing the Rootable Older Kernel

1.  Double-click on flashtool-0.9.11.0-windows.exe you downloaded above and follow the on-screen instructions to install it.

2.  Copy the Xperia_Acro_S_LT26w_6.2.B.0.211_KernelOnly.ftf file you downloaded above to C:\Flashtool\firmwares on your harddrive.

3.  Open the Flashtool application after installation and click on the Flash icon (the one with the thunder symbol).

4.  You should be presented with two options:  Flashmode and Fastboot Mode.  Select Flashmode.

5.  Choose Xperia_Acro_S_LT26w_6.2.B.0.211_KernelOnly.ftf and click on OK.  Follow the on-screen instructions on how to boot your device into fastboot mode and connect your device.  Also, make sure “No Final Verification” is marked.

6.  Reboot device.

IV.  Rooting the Xperia Acro S

1.  Enable USB Debugging on your device.  You can do this by heading to Settings > Development Options > USB Debugging and checking the tickbox next to it.

2.  Enable installation of non-Market applications.  To do this, go to Settings > Security and check the Unknown Sources tickbox.

3.  Connect your device to your Windows PC.  At this point, ensure that the Flashtool is not running; if it is running, exit it and check the task manager for any other instances of it running and end them.

4.  Extract the DooMLoRD_Easy-Rooting-Toolkit_v18_perf-event-exploit.zip that you downloaded above to a folder on your desktop.

5.  From the extracted folder, double-click on runme_win.bat to run the DooMLoRD tool.

6.  Follow the on-screen instructions and wait for the process to be complete.

Reboot your device and check that the SuperSU app is installed on your device.  If it is, you are now rooted!

V.  Flashing the Original Kernel

Follow the same steps listed in section III of this guide but choose Xperia_Acro_S_LT26w_6.2.B.1.96_KernelOnly.ftf this time.

    Having a bit of an issue even though I followed the steps to the letter.

    Q: Does flashing the kernel to .211 change the build number?

    DoomLord’s easy rooting toolkit had this to say even after downgrading the kernel to .211:
    “LT26w (6.2.B.1.96) is not supported.
    You need to manage to get remap_pfn_range addresses.”

    Any advice?

    Hallo. Does not work for my device, tried it several times – no success. (Austria)

  • Frederick Yang

    For some reason, I can’t put the device in to “flash mode” (what ever that means) when Flash tool prompts me to do so. I’ve turned the device off, Then held down the back button while plugging in the USB Cable… Nothing… Device simply goes in to charging mode. Can someone please advise? Thanks.

    • Stray Ancient

      For Acro S its different.

      Turn off your phone.
      Hold the volume down button while plugging in the usb cable and voila!

      • Frederick Yang

        Thanks for that, was able to successfully get in to Flash mode. However, after complete step III, restarted my phone and the version / build number is still saying 6.2.B.1.96? Is it suppose to change back to .211 when I view “About phone”? Thanks.
