How to Root the Sony Ericsson Xperia Neo V (MT11i) running Android 4.0.4 with a locked bootloader

The Sony Ericsson Xperia Neo recently got updated to Android 4.0 and while that is great news, it broke root access for many users.  This guide will show you how to fix that and regain root – read on to know how.

I.  Before You Begin

1.  This procedure works on the Xperia Neo V with a locked bootloader running Android 4.0.4.  If you have an unlocked bootloader, look to our post on the same to know how to root it.

2.  Remember to back up your data before you proceed any further!

3.  Make sure you have set up ADB before you proceed with this guide.  If you haven’t, read up on our post on how to do this.

II.  Necessary Downloads

1.  .431 Firmware (download the .431 ftf firmware for your device and save it to your computer)

2.  Flashtool v0.8.6.0.

3. .562 Kernel tft (download the .562 ftf firmware for your device and save it to your computer)

3. Root zip (download the .zip file under downloads)

III.  Flashing the .431 Firmware

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

2.  Copy  both .ftf files 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 the kernel with the version number .431 in it and click on OK.  Follow the on-screen instructions on how to boot your device into fasboot mode and connect your device. Also, make sure”No Final Verification” is marked

6.  Reboot device.

This will have flashed your kernel back to .431 which is rootable.

IV.  Flashing the MT11i_4.1.A.0.562 Kernel

1.  Follow the same steps as described in Section III above until Step 5.

2.  On Step 5, select MT11i_4.1.A.0.562 instead of MT11i_4.1.B.0.431.

3.  Continue with the rest of the steps as in Section III.

You should now have an Xperia Neo running the .431 firmware but running a .562 kernel.

V.  Rooting the Xperia Neo V

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

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

3.  Connect your device to your Windows PC.

4.  Extract the DooMLoRD_v1_Xperia-2011-ICS-ROOT-emu-busybox-su.zip that you downloaded above to a folder on your desktop.

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

6.  Follow the on-screen instructions and wait for the process to be complete (your device will reboot several times during the procedure).

      Can anyone answer the above post? That happened also to me after following the steps. I’ve downloaded Root Checker Pro and confirmed that SuperUser and busy box was installed but the problems is that SU binary not found or not operating properly. Please do answer. Thanks a lot if someone responded.

    • Dax Krishna

      are you saying all this happened after you followed the procedure above or is this an entirely different problem? as far as I know, rooting your device should not cause the problems you are facing.

  • Juzer

    Hello i followed the procedure several times the problem is my kernel is flashed but in the flashtool it says phone will reboot and it doesn then it again says for flashtool unknown sources and debugging must be checked in and phone connected in flash mode ive checked both the setting of debuggin and unknown sources still cannot flash the kernel ive officially updated to 4.0.4 .431 firmware plz help

    • Mahesh Makvana

      Do you have locked bootloaders? The process works for the device having locked bootloaders.

  • SACHIN

    I FLASHED THE FIRMWARE AS WELL AS THE KERNEL BUT WHEN I USED THE ROOTING TOOLKIT ITS SHOWING

    I followed the instructions to a tee but now my xperia neo only shows the Sony and Xperia logos with a black background and it wont turn on…..HELP!!!

    • Dax Krishna

      did this happen after you completed everything or somewhere during the procedure? at exactly what step did this happen Rachel?

      • Rachelki

        After flashing the .431 firmwear the phone didnt reboot just went between Sony and Xperia logos and continues to do so.

        • Dax Krishna

          put your device into flashboot mode and try flashing .431 again, make sure that No Final Verifciation is unchecked!

          • Rachelki

            Once it is flashed, do I turn the phone on or should it re boot itself?

      • Rachelki

        Do you think I can fix it???

    Can we root the fone after we’ve officially upgraded it to ICS 4.0.4

  • Aniket Tamboli

    Hey! I can’t thank you enough for this How-To. Finally found a clear rooting guide for the Neo V. I’m gonna root my phone in just a bit, but I just wanna know if during the process of rooting, the bootloader gets unlocked too? Because from whatever I’ve read, the bootloader needs to be unlocked if I want to flash custom recoveries and ROMs.

    • Mahesh Makvana

      The root procedure doesn’t unlock the bootloader and you don’t require unlocked bootloader to root the device.

      But if you’re planning to get a custom recovery, you’ll require the bootloader to be unlocked.

      Hope it helps!
