Sony Xperia acro HD root GUIDE / TUTORIAL​

This is a rough translation from ふーか (HUHKA)'s Blogger posted on June 27, 2012

rooting toolkit for XPERIA acro HD (ver1.0.1)

In this version:

・ KDDI’s IS12S

・ docomo’s SO-03D

Both versions are supported.

Batch bugs are fixed.

Installation process revised.

Important Points

-This process goes outside of what the manufacturer and carrier’s warranty covers.

Whatever may happen to your device, do not rush into a shop with your problems.

You are responsible for you own actions.

-Installation wipes data.

Please back up your data and necessary applications before beginning the installation.

-During the installation process you will be flashing the global XPERIA S LT26i ROM

The device’s battery charge will continue to deplete while flashing.

While installing the LT26i ROM your battery’s charge will fall and you might not be able to recharge even when the device is powered off.

-If you are not able to restore your phone with SEUS or ftf flashing with Flashtool then you might end up with a bricked phone.

-Please make sure you phone is charged to 100% before installation!

-The installation process is a pain in the butt and complicated. It’s also full with traps that might end up bricking your device.

If you are thinking of just giving it a shot and are careless then the chances of a bricked phone will be very high.

If you have trouble with understanding batch operations and the command prompt then you shouldn’t try to root your phone using this installation guide.

-You will need an empty folder labeled ‘files’ for the installation files.

Please keep this folder inside of the acroHDrootingKit folder.

-The ‘files’ folder should be empty.

Please move the required files into the ‘files’ folder after you have acquired them.

*The binary files are not distributed.

Please use your own means to attain them.

*During this step your device will not charge even if connected via the USB cable.

*Please be aware that if your device powers off due to low battery there is a chance of the phone bricking.

You have very little time before the boot up finishes so work fast!!

After your boot set up is complete you will see ‘acore process closed (stopped working) unexpectedly’, just close the dialog box and wait for the phone to settle.

Set your language as Japanese and skip the KDDI security.

Repeat [Steps] (2) - (6)

Connect the device to the PC via USB and execute step3.bat.

If the process doesn’t execute or connect correctly, stop the batch process and execute again.

Wait for the batch process to complete. （You are waiting for the ADBD to finish）
