For now i dont know kung working pa ito kasi halos lahat ng firmware ngayon eh via SUS at PC companion. There's a new method for rooting.
How to Downgrade and Root .62 firmware without Unlocking Bootloader (Xperia 2011 devices)
Based on my experience, karamihan sa xperia 2011 devices walang FOTA ( Firmware On The Air) update or kaya hindi pwede mag upgrade ng firmware via WIFI or Packet Data (3G)
Marahil para maiwasan na rin ung Hard Brick ng mga phone if ever na nag-unlock ng bootloader.
Ginawa ko itong tutorial na ito para sa mga ayaw mag-unlock ng Bootloader para ma- maintain ang warranty.
Note: Hindi kasi naro-Root ang .62 Firmware kaya ito na ang Solution.
Steps:
I. Downgrade to .42 firmware procedures:
1. Download muna natin itong Flash tool here:

saka ung firmware na based sa model ng phone ninyo: forum.xda-developers.com/showthread.php?t=1477440
2. Install Flashtool
3. Copy paste mo ung FTF file or firmware na nadownload mo sa C:\Flashtool\firmwares
4. Run the Flashtool application
5. install PC companion para mabasa ung phone ninyo tru PC.
and Download then install this

6. Go to flashtool, click mo ung thunder icon then flash mode > ok > ok
7. Turn off your phone then press and hold ninyo ung volume down button
Make sure na more than 50% ung battery level ninyo.
8. While holding the volume down button, plug na ninyo ung usb cable from pc to phone.
9. Magkape muna and wait until finished.
II. Rooting Procedures:
1.) From your Phone:
Go to Settings > Applications > Check Unknown sources
2.) Go to Settings > Applications > Development > Check USB debugging
3.) Plug your phone by USB cable to your pc.
4.) From your PC:
Download this

5.) Extract the downloaded file then Run the Runme.bat
6.) Wait until the process was finished.
7.) Then your phone will be automatically reboot.
8.) after reboot, check your menu if there's a Superuser ICON. kung nandun nga ung ICON
ROOTED na PHONE mo.
III. Upgrade your Phone to .62 firmware via wifi or packet data:
1. Make sure na more than 50% ung batt ninyo, nakasalpak ung sim ninyo at tama ang "Date and Time" ninyo.
Open your wifi. connect your phone to wifi hotspot with stable internet connection or load muna kayo then use packet data.
2. From your phone, go to menu then update center
3. Wait then tap Download then ok. then wait mo matapos madownload.
4. then Install na ninyo and after that magrereboot kusa iyan. Maraming beses yan magrereboot.
5. Ingatan na wag magalaw ung phone while installing the firmware.
6. Magrereboot ulit yan. un ok na. Hindi mawawala ung Superuser ninyo.
Oh ayan gumawa na ako ng Tutorials para sa inyo. wahahaha ang haba niyan. Feedback nalang kayo. Tried and tested ko na yan sa Xperia mini ko at Xperia Mini pro ng friend ko.
