Firstly, head over to (here) and hit thanks to puppet's thread. Also hit thanks to any of his other post. Two thanks for him per every thank to me. :)

I. Downgrade:

Since rooting directly in 4.0.4 is not possible, one needs to downgrade to a rootable GB ROM to root. (Skip this step if you are already in GB).

To Downgrade, you need to flash an old GB ROM ftf to your device.

Download ftfs from here:

Thanks to someguyfromhell
Then use flashtool to flash the ROM, as described in the images below.






II. Root the GB ROM:

(Skip this step if you are already in Rooted GB)

Download the DoomLord's Easy Root Toolkit for Xperia Gingerbreade >= .58 from here.
Extract the files somewhere.
Connect the device to the computer, and run the file "runme".


Follow onscreen instructions.
When done, device will reboot, and you should see application called SuperUser in your app drawer.

III. Preparations to root 4.0.4 ROM:

Download the XperiaRoot.rev3 from here.
Extract the files somewhere.
Connect the device to the computer, and run the file "01-local-prop".


Follow on screen instructions.
When done, /data/local.prop should be edited as desired.

Here, do not do anything on cell and directly proceed to Flashing the 4.0.4 ftf.

IV. Flash 4.0.4 ROM:
***See Note below
Download the ftf from the following links:

SK17i: Here or Here
SK17a: Here or Here

Xperia Live with Walkman:

Thanks to davidcmc

Thanks to shufuking, Thanks to expeacer

Xperia Ray:

Xperia Arc S:
LT18:Here OR Here OR Here

Xperia Neo V:
MT11:Here OR Here

Xperia Neo:

Xperia Arc:
LT15: Here OR Here

Xperia Pro:

In case some links are dead try out this ftp site (open preferably in Internet Explorer):
Go to Incoming and then Sony Updates, and you can find the ftfs there. [Thanks to MSTHETERROR]

Proceed as you did in downgrading, placing the 4.0.4 firmware in /firmware folder this time; and selecting it in step 4.
In step 4, make the check boxes look like this.


Proceed with the flashing Process.

Here, you can also use PC Companion or Sony Update Center if you want for updating. While updating with SUS, make you sure you perform the recommended install and do not wipe data.

Once the flashing is done, turn ON the device (If using PCC or SUS you will be prompted to turn ON). During the first boot, the device might reboot. In that case, after second boot it will turn on normally.
In case it gets into bootloop, proceed to next step right away.
Else proceed to next step with your phone turned ON.

V. Root 4.0.4 ROM:

From the Xperia-ROOT.rev3.zip file you downloaded earlier in step 3, open the file 02-push-root-files.cmd.


Follow the on-screen instructions.
Device will reboot.
Once re-boot is done, you will have SuperUser installed in the 4.0.4 ROM.

Note: Using this method, you can also root .62 GB firmware. For this, just flash the .62 ROM in place of 4.0.4 ROM, in step IV.


Hit Thanks if this post helped you in anyway.

Just one question, since I still haven't got it clear: when you say "remove local.prop" you mean i have to remove the whole file or just edit it and delete "ro.kernel.qemu=1" line?

After puppet updated his script to v3, the file is removed automatically.
In case you had rooted using the earlier versions, then you need to remove the file from \data.
Else, if you used v3, you need not.
(Android OS builds this file automatically if it is not available)

I have a Xperia Mini Pro, but there is not an update for ICS in my country available yet. Do I have to wait for it?
No. You need not. If you follow according to this thread, you will get the ROM along with root, without waiting for Sony to release it.

Note: Your warranty might get void in carrying out these steps.

Who said you will void your warranty? :O
Anyway, I suppose that if you take the phone to SE Centre and they find out you have installed, for example, a generic firmware, they could tell you that you voided your warranty. Maybe. Dunno :D

I have a little problem even tho everything went as described in the tutorial, and I apparently have root access (superuser is installed and prompts when I try to give apps like ES Explorer root access and other stuff). BUT, titanium backup doesn't seem to work, it doesn't acknowledge that I got rooted and thus it doesn't work. Tried installing busybox, that went ok, but still titanium backup doesn't work... any help would be appreciated!

sorry nvm.... either the reinstall of titanium backup or another reboot solved it all
