As some ones of you including me still have not unlocked the bootloader at unlockbootloader.sonyericsson.com simply because not willing to lose the functionality of DRM and the TrackID, here comes another solution.

***WARNING***
The following operations may harm your device and your warranty may be void.
Neither I nor any other forum members mentioned below will be responsible for any of your loss.
Continue reading at your own risk!

***WARNING***


[requirements]
  • A 2011 Sony Ericsson XPERIA device with a still looked bootloader (this should work on all the 2011 XPERIA models but I have only tested on an XPERIA ray)

[referencing links]
  • Reading all the links below before conducting any operation is strongly recommended.

[unlocking your bootloader]
  • Find the test point of your device (see the referencing links, you may have to register an ID at support.setool.net to view some of the attachments)
  • Download s1tool from this thread and extract the 7z file
  • Turn off your phone
  • Connect the USB cable shield and the test point with a paperclip or some other wire
  • Attach the USB cable to your PC, when Windows finds a new device, disconnect the test point and manually install the driver contained in the s1tool.7z archive
  • Run s1tool.exe, click “Patch SEMCBoot” then follow the instructions on the screen and your bootloader will be unlocked

After the bootloader is unlocked, you can flash custom kernels or do something else like rooting your phone etc.

I am using an XPERIA ray* and I have unlocked my bootloader then rooted it. The TrackID works and no side effects found yet. Currently I have no idea about how to relock the bootloader so do this at your own risk.

Below is my s1tool log:
Code:

on a rooted device you are always able to flash what firmware you like.
I personally try to compile cm7.1 for my mango so I am switching almost daily between stock & CM firmware
