Here it is the solution for rooting without dowgrading
Requirement:

2. ST15i Latest ICS Firmware: (You can use your own FTF file of 4.1.B.0.587 of ST15i, the one below is PH Firmware)
ST15i 4.1.B.0.587 PH Firmware
3. ST15i Kernel for the latest Firmware:

6. Rooting toolkit:

Instruction:
1. Install flashtool
2. Extract the 3 zip files containing the latest PH firmware for ST15i on C:\Flashtool\Firmwares\
3. Copy ST18i kernel at ST15i kernel on C:\Flashtool\Firmwares
4. Flash the firmware using flashtool
5. Go through the initial setup process and turn on Debugging mode and Installation from Unknown resources. This is important.

Go to settings > Security > Mark "Unknown sources"
Settings > Developer options > Mark USB debugging
Settings > Xperia > connectivity > USB connection mode > select MSC mode

6. Now turn off the phone and this time flash ST18i kernel. Yes ST18i and not ST15i.
7. Now turn on the phone and wait for about 1-2minutes. Yes it will stay on black screen. That's normal.
8. Now connect your phone on PC. Turn off your antivirus temporarily and extract the rooting toolkit and run "runme.bat"(The phone is still black screen and that's normal )
9. Follow the onscreen instruction Allow the phone to reboot and when it is done, wait for 1 minute to be sure.
10. Disconnect the phone and remove the battery and reinsert it again.
11. Run flashtool and this tim flash the ST15i firmware.
12. Turn on the phone and enjoy your rooted ST15i.

Yes there is a way, but you would have to unlock your bootloader and flash a custom kernel. After that install it in cwm

For the firmware links maybe this could help you :good:

Dear, I am new here. I hv updated my device's android version using sony pc companion. I am upgraded to 4.0.4.
But I have no idea on how to root. I am unable to install many apps as I do not hv root access. I want my device to be jellybean 4.2
I would be highly obliged if you kindly impart me on how to do this.

You will loose all data on phone!

Okay here you go:
1. Unlock your bootloader. How yo do this is in my guide, but remember it will void your warranty
2. Install Flashtool and all the drivers from the flashtool installation folder for all devices and modes.
3. Download FXP cm10 (Android 4.1.2 - mostly working) or cm10.1 Alpha (4.2.1 - many things not working, for more details see the thread by shufuking) and copy the rom zip to the sdcard of your phone.
Download the Google apps (gapps) for jelly bean 4.1 or 4.2 (depending on which rom you choose) and copy it to sdcard too.
4. Extract the zip on your PC, copy the boot.img to a folder named "kernels" (that you have to create in the Flashtool folder).
Launch Flashtool, click on the flash -> fastboot mode.
5. Click "reboot into fastboot mode" or shut down the phone, wait 10 seconds, hold volume up and while holding volume up connect the usb to pc. Now the blue led lights up
6. "Select kernel to flash" and select the boot.img in kernels folder.
7. Wait until the image is flashed, now unplug you phone.
8. Power on phone and while it's powering on press volume down again and again to get in clockworkmod recovery (cwm)
9. Select wipe data/factory reset (you navigate with the volume keys and select with the home button) and wipe cache.
10. Go to advanced -> wipe dalvik cache
11. Install zip from sdcard -> choose zip -> choose the rom zip and install it
12. Install zip from sdcard -> choose the gapps
13. Now reboot the phone and enjoy

That's it, for any other questions just ask :good:
