Unlocking Bootloader. Xperia 2011. Test Point Method

Update: It seems that the MDPI devices which were manufactured at later times have been implemented with Sony protection, which does not allow you to unlock the boot-loader with the current version of s1Tool. You will need to use the Official Sony method and loose the DRM keys in the process.

Follow the following steps to unlock the bootloader of your Xperia 2011 device.
Unlcoking bootloader lets you flash custom kernels and ROMs to your device.
If you end up doing something wrong, flash firmware using flashtool.
I do not care if you spill coffee on your phone while doing all this. I will try to help you as much as I can, in such a case, but I can never guarantee

If you unlock your bootloader by this method, you will not loose the DRM keys of your phone. This means that apps like Track ID will work even on unlocked bootloader.
You can lock your bootloader again, and flash the stock Sony Firmware, and your phone will be as it was when it came from factory.

2. Short Piece of Wire
