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 (taken from ):

!4.0.2.A.0.62 -
Xperia Mini Pro (SK17i)

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:

Xperia Mini Pro:

SK17i: Here
SK17a: Here
Thanks to Jozinek

Xperia Live with Walkman:
WT19a: Here
Thanks to davidcmc

Xperia Mini:
ST15: Here
Thanks to expeacer
[I]Thanks to shufuking[I]

Xperia Active:

Xperia Ray:

Xperia Arc S:
LT18:Here or Here

Xperia Neo V:

Xperia Neo:

Xperia Arc:
LT15: Here

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, during the first boot, the device will reboot. 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 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.
You can also use Sony Update Service, for updating to 4.0.4 (or .62 firmware) in step IV. Rest of the procedure remains the same.


Hit Thanks if this post helped you in anyway.

There's already a thread about rooting 4.0.4. Downgrading to GB is not needed, you just need to flash a rootable 4.0.3 kernel, as explained thoroughly there.
Please contact OverLo4d to add the files for Mini/Mini Pro in the OP and credit you accordingly.

@everyone: Please no more rooting threads, I am at the end of my rope here.

Thank you for your cooperation!
