Official unlocking needs IMEI to create the code, who knows if it is logged or not.

Test point method loses warranty also, because bootloader is patched.
You do keep DRM, but once it is lost, it is lost forever.

If u unlock bootloader using sony method u can flash .ftf file to relock it and sometimes sony's employee can think that was never unlocked.

But after this method it is IMPOSSIBLE to relock bootloader.

Because it was never unlocked.
Bootloader can be restored in the same application.

The warranty is not void also, the bootloader in service test menu it still "unlock allowed: Yes"

Sony dont look inside Service Menu. They have other method to find out that phone is/was unlocked i think. No difference their method/test point.
They can connect to pc and start fastboot for example. Sony's method is possible to relock this not. But i dont know how they do this if phone completely dont start?

They aint gonna use fastboot just because of you and your bootloader. They use EMMA to flash, debrick, repair ta, etc. If the phone is completely bricked is gonna cost money, thats it.

Tried, and tried, and tried... my PC simply doesn't asks for drivers when I connect my st15 test point and plug the USB cable... I suppose I'll give up.

For me worked.

I took a wire of an old battery charger then I soldered a segment of clip of paper in the extremity. I sanded the clip to clean the metal and to give better surface for contact. I isolated half of the clip to hold, just to prevent some issue. The other extremity without the clip, I made contact with the battery minus, see the image attached.

Then I plugged the USB cable and the windows 7 try to install the drivers.
